The reason that the SSD vs. HDD debate is so important for the enterprise is the massive size and volume of today’s data. Part of the challenge is that this hugely growing data is threatening traditional computing infrastructure based on HDD, or hard disk drive storage.

The problem isn’t simply growth. If that’s all there was to it, then data center admins could simply slap more spindles, install a tape library, and send secondary data to the cloud where it becomes the provider’s issue to contend with. But the problem isn’t only growth; it is also the speed at which applications operate in their environment. Processor and networking speeds have kept up with application velocity and growth but production storage has some way to go.

Granted that computing bottlenecks may exist in other areas than just the HDD. Switches will fail, bandwidth can overload, VM hosts sometimes go down: nothing in the computing path is 100% reliable (even 99.9% can be a heady stretch).

Although, common census suggests that HDD disk drives are a major slowdown culprit in high IO environments. The nature of the mechanical device is the offending attribute.

The Important Factors

Very fast SSD performance is the increasingly popular fix for the mechanical disadvantage of the HDD. However, SSDs are not the automatic choice over HDDs in the server environment. First, one-to-one, SSD pricing is a good deal more expensive than HDDs. There are certainly factors that narrow the purchasing gap between SSDs and HDDs, and theoreticall the cost for SSDs can be less.
A second factor is what to actually replace: SSD performance will be faster than disk, but this does not necessarily mean that IT needs this performance level for secondary disk tiers – and over redundancy can result.
A third factor that mitigates against universal replacement is reliability: are SSDs really reliable enough to replace HDDS in the data center? Let’s be more precise: SSD/HDD reliability depends on numerous factors: usage, physical environment, application IO, vendor, mean time before failure (MTBF), and others. This is well served discussion topic, so to keep this performance/reliability discussion to a useful focus, let’s set some base assumptions:

 

1. We’ll discuss SSDs in data centers, not in consumer products like desktops or laptops. SSDs have a big place there especially for devices carried into hostile environments. However, the enterprise has a distinct set of requirements for storage based on big application and data growth, and the to-use-or-not-to-use question is critical in these data centers.
2. We’ll limit our discussion exclusively to NAND flash memory-based SSDs with the occasional foray into DRAM. This limits the universe of flash technology as the discussion point: DRAM is not a flash technology at all. And in the case of NAND SSDs, remember that while NAND is always flash, flash is not always NAND.
3. We’re leaving out discussion of other storage flash technologies, which lets out all-flash arrays with ultra-performance flash module components, or server-side flash-based acceleration including hybrid variants. These are big large factors in and of themselves but do not represent the majority of the SSD market today, particularly in mid-sized business and SMB.

Performance: SSD Wins

Hands down, SSD performance is faster. HDDs have the inescapable overhead of physically scanning disk for reads/writes. Even the fastest 15 RPM HDDs may bottleneck a high-traffic environment. Parallel disk, caching, and lots of extra RAM will certainly help. But eventually the high rate of growth will pull well ahead of the finite ability of HDDs to go faster.

DRAM-based SSD is the faster of the two but NAND is faster than hard drives by a range of 80-87% — a very narrow range between low-end consumer SSDs and high-end enterprise SSDs. The root of the faster performance lies in how quickly SSDs and HDDs can access and move data: SSDs have no physical tracks or sectors and thus no physical seek limits. The SSD can reach memory addresses much faster than the HDD can move its heads.12

The distinction is unavoidable given the nature of IO. In a hard disk array, the storage operating system directs the IO read or write requests to physical disk locations. In response, the platter spins and disk drive heads seek the location to write or read the IO request. Non-contiguous writes multiply the problem and latency is the result.

In contrast, SSDs are the fix to HDDs in high IO environments, particularly in Tier 0, high IO Tier 1 databases, and caching technologies. Since SSDs have no mechanical movement they accelerate IO requests far faster than even the fastest HDD.

Reliability: HDD Scores Points, but SSD isn’t far off

Performance may be a slam dunk but reliability is not. Granted that SSD’s physical reliability in hostile environments is clearly better than HDDs given their lack of mechanical parts. SSDs will survive extreme cold and heat, drops, and multiple G’s. HDDs… not so much.
However, few data centers will experience rocket liftoffs or sub-freezing temperatures, and SSD High Speed Servers have their own unique stress points and failures. Solid state architecture avoids the same type of hardware failures as the hard drive: there are no heads to misalign or spindles to wear out. But SSDs still have physical components that fail such as transistors and capacitors. Firmware fails too, and wayward electrons can cause real problems. And in the case of a DRAM SSD, the capacitors will quickly fail in a power loss. Unless IT has taken steps to protect stored data, that data is gone.
Wear and tear over time also enters the picture. As an SSD ages its performance slows. The processor must read, modify, erase and write increasing amounts of data. Eventually memory cells wear out. Cheaper consumer TLC is generally relegated to consumer devices and may wear out more quickly because it stores more data on a reduced area. (Thus goes the theory; studies do not always bear it out.)
For example, since the MLC stores multiple bits (electronic charges) per cell instead of SLC’s one bit, you would expect MLC SSDs to have a higher failure rate. (MLC NAND is usually two bits per cell but Samsung has introduced a three-bit MLC.) However, as yet there is no clear result that one-bit-per-cell SLC is more reliable than MLC. Part of the reason may be that newer and denser SSDS, often termed enterprise MLC (eMLC), has more mature controllers and better error checking processes.

The Final Thoughts?

So are SSD High Speed Servers more or less reliable than HDDs? It’s hard to say with certainty since HDD and SSD manufacturers may overstate reliability. (There’s a newsflash.) Take HDD vendors and reported disk failure rates. Understandably, HDD vendors are sensitive to disk failure numbers. When they share failure rates at all, they report the lowest possible numbers as the AFR, annualized (verifiable) failure rates.

This number is based on the vendor’s verification of failures: i.e., attributable to the disk itself. Not environmental factors, not application interface problems, not controller errors: only the disk drive. Fair enough in a limited sort of way, although IT is only going to care that their drive isn’t working; verified or not. General AFR rates for disk-only failures run between .55% and .90%.

However, what the HDD manufacturers do not report is the number of under-warranty disk replacements each year, or ARR – annualized rates of return. If you substitute these numbers for reported drive failures, you get a different story. We don’t need to know why these warrantied drives failed, only that they did. These rates range much, much higher from about 0.5% to as high as 13.5%.

 

Do we, as Webmasters, ultimately want SSD High Speed Servers Storage Advantage? Absolutely Yes. Although…

 

We have also heard stories relating to SSDs Storage Devices losing data when they are put into cold storage for extended periods although this discussion is ongoing. Not something we have directly encountered either.

Check your SEO Stats for Free!

Benefits of using Check SEO Stats

If you want to check SEO stats for your website then go to www.checkseostats.com and get tested! Go on do it!

Just type in the URL of your website to the search engine box and a lot of statistics will come out. They will tell you the areas where you need to improve on and the areas where you are already doing better. They give you the domain age. You better be aware of how long you bought your domain because if it is only for one year and you see it is already near 300 days old then it is going to expire soon. You would not want someone to steal your domain especially if you have a website name that a lot of people want. It will also give you the Alexa ranking which is the website’s traffic ranking out of the millions of websites in the world. You have to realize there are a lot of websites in the world so you don’t have to feel bad if it is ranked low. This ranking is something you should always monitor. If it goes up then you must be doing something right but if goes down then you must be doing something wrong. It will also display your Google Page Rank which is a rank on Google when a lot of people search your website. If it goes up to 1 or 2 then a lot of people go to your website via Google each and single day.

It is ideal to go back to the website every now and then as it is awesome to check SEO stats here as it gives the status on numerous things like the Malware detection. It will tell you if the website is free from malware and any other harmful codes. It will also indicate if it is safe to use by users so this website can also be used by people who would want to check out your website. If they see your site is not safe then that raises a red flag for them. They also give the status of Meta Tags which are the keywords, description and title. If the title is original then the status will most likely be good. This is why you must spend a lot of time thinking of a good title. If there is no description then that is a bad sign as it won’t take a long time to put one in. It can be one phrase that describes what the website is all about. For example, if it is a food blog then the description could be “Reviewing local restaurants one by one”. If it is an amusement park then it could go like “where the fun starts..”. If it does not have a description then you can expect the status to read “Bad”.

You have to put everything you have in your website since it is a representation of whatever it is you decide. It also gives the status of the site if it is online or not since some sites could be down due to the regular maintenance. There is also a possibility the site is hacked by some genius hackers. The response time is also indicated there and it is usually less than one second. It also lists down your scores for Google Backlinks, Google Indexed Pages, Bing Backlinks and Dmoz. It really pays off to exchange backlinks with other websites because that will increase your ranking in Google. Remember, Google is the search engine everyone goes to when they search for something so better get a high ranking there. It will also say whether or not the server IP is blacklisted or not. If it is blacklisted then it is means it is involved in some kind of online behavior that is unusual. The website also provides social stats including how much Facebook shares it gets as well as Twitter. If you got a social media team working for you then you will know if they have been effective or not. Other social media sites they keep track of are Pinterest, Linkedin, StumbleUpon and Google Plus. Social media is the best way to make your presence felt on the Internet so a good number there would definitely help.

What is SSD HDD Website Hosting?

Ever wondered what the benefits of an SSD HDD would be to your website speed? We want to discuss the benefits of using an enterprise grade SSD HDD to host your website.

Like a memory stick, there are no moving parts to an SSD. Rather, information is stored in microchips. Conversely, a hard disk drive uses a mechanical arm with a read/write head to move around and read information from the right location on a storage platter. This difference is what makes SSD so much faster.

SSD Vs HDD Web Hosting? What is the difference?

The traditional spinning hard drive (HDD) is the basic nonvolatile storage on a computer. That is, it doesn’t “go away” like the data on the system memory when you turn the system off. Hard drives are essentially metal platters with a magnetic coating. That coating stores your data, whether that data consists of weather reports from the last century, a high-definition copy of the Star Wars trilogy, or your digital music collection. A read/write head on an arm accesses the data while the platters are spinning in a hard drive enclosure.

An SSD does roughly the same job functionally (saving your data while the system is off, booting your system, etc.) as an normal HDD, but instead of a magnetic coating on top of platters, the data is stored on interconnected flash memory chips that retain the data even when there’s no power present. The chips can either be permanently installed on the system’s motherboard (like on some small laptops and ultrabooks), on a PCI/PCIe card (in some high-end workstations), or in a box that’s sized, shaped, and wired to slot in for a laptop or desktop’s hard drive (common on everything else). These flash memory chips differ significantly from the flash memory in USB thumb drives in the type and speed of the memory. That’s the subject of a totally separate technical treatise, but suffice it to say that the flash memory in SSDs is faster and more reliable than the flash memory in USB thumb drives. SSDs are consequently more expensive than USB thumb drives for the same capacities.

Bringing ITC into the modern office

Whiteboards that offer a print function are so last decade. So what are the must have items to bring into the modern office environment?

We decided to ask our friends at Ironline Technology: What are the must have new items for the modern office this year?

Here’s what they said:

Thanks for the email, and we had a lot of fun preparing this short list of must have technology for the modern office environment. Obviously, the nature of the business normally dictates the technology requirements. So we are taking the approach of a ‘normal business office’ – whatever that may be.

Comms

Handsets and telephone systems have come a long way in the past few years. The normal technology now consists of VOIP and electronic routing for calls. Options such as call screening, recording, forwarding and voicemail are just the beginning. Our most popular business phone system is rapidly becoming the Cisco IP 7945 Gig Ethernet Color as it has a very handy organisation system and is jam packed with the latest technology.

Softphones and SIP

Another leading brand is 3CX and their range of softphone SIP options. This enables rapid expansion of services and being software driven, you only pay for the service level that is most appropriate.

Displays

The best way to capture attention is with a very good display. You can capture your local foot traffic, passing motorists, waiting room clients and even your staff in meetings will be more attentive when viewing your pitch on a good monitor. The cost of these monitors has fallen sharply and is at an all-time low. Take for example the Sony Pro Bravia LED 60″ 13KDL60W600BPSD for under $1,500 – cannot get much better than that!

SSD Hosting for Australian Webmasters


Exalt is your perfect choice as an SSD hosted Australian based server environment.

Tired of using poor quality low-cost options from the likes of CD or GD? We won’t blame you… we had the same dilemma. So we started Exalt.net.au to fix it.

Our servers are located in Australia and run the latest in SSD HDD and fast processing speeds, to get your WordPress, Joomla, Drupl or Magento sites moving at lightning speed and serving your Australian visitors at the highest possible service level.

To have a website, you’ll probably also need a domain name and a web hosting environment. There are a lot of well-known and reliable providers out there that will offer both web hosting and the domain name registration functions. However, you may unaware of local web hosting providers in Australia. Do a quick search on Google, Yahoo! or bing to see if any exist in your area. Having a local web host is very beneficial.

Local Aussie Web Hosting

Usually when a domain name is purchased, website hosting is also offered and it’s really convenient to purchase it then too – as it means a simultaneous billing cycle for both costs. If you’re willing to work with a good provider, they can set everything up for you.

Benefits of Local Website Hosting

  • Relationships – Knowing someone locally will help establish a more solid business platform for the years ahead.
  • Face-to-Face – You can always meet in person or visit their facilities.
  • Support local jobs – Keeping Australians employed and on the cutting edge of technology
  • Customer Service – if you need help, you can pick up the phone and be able to talk with someone instead of an automated machine.
  • Faster Serving Speeds – Due to the shorter distance of the response, local Australian users typically experience improved speeds, saving your users valuable time in browsing your website, and improving your search engine results in the process.

Disadvantage of Using a Local Website Provider

  • Availability – You may not be able to contact your web host 24/7 and 365 days per year. Be sure to check with your local website host for their service hours. Exalt offer 24 hour chat support and uptime monitoring to ensure you are stable rain hail and shine.
  • Cost – normally local web hosting is a little bit more expensive. Sometimes people look at this as a disadvantage. However, I don’t believe paying a couple extra dollars per month is a genuine disadvantage. With local hosting, we believe in providing top quality customer service and we think you end up with a more quality service. And you are always able to call and speak with someone you trust that talks your language. In today’s day and age, we believe that there should be more value placed on customer service, and one of the best ways to get this is to buy local and use SSD Hosting for Australian Webmasters, exalt.net.au/

Web Hosting Australia

Again, even though the cost may be slightly higher that what you are currently paying for your Web Hosting in Australia – working with a local web host has more benefits than disadvantages. Although paying for the storage and bandwidth can be done overseas at a cheaper outright cost, using a local Australian web host will allow you to get more personal and friendly service.

Have you used a local web host in Australia before? How has it compared to your cheaper alternatives overseas? Let us know in the comments section below.

The best songs to code to

A frequent topic of discussion (read arguement) at our offices is “who chooses the music?”

We are a mixed group of ages and demographics… and our music tastes vary considerably. We got inspired by Mashable’s recent post about ‘The Best Songs To Code To” and wanted to pay tribute to some of ours.

Jimmy is a head WP developer:

Digitally Imported Chillout stream, I pretty much only code to that: http://www.di.fm/CHILLOUT 

Sublime chillout downloadable freely: http://www.kahvi.org/releases.php?release_number=203

Also, Carbon Based Lifeforms – “Silent Running” or “Or Plan B” are absolutely astounding to me.

Jonah is a manager:

Anyone else remember the horribl(y awesome?)e Starbucks commercials from a couple of years ago where a chorus would sing “Eye of the Tiger” with the beat replaced by someone’s name?

edit- Youtube is the collective consciousness of our time. http://youtube.com/watch?v=14qeu7JRwt0Apparently it’s not a chorus, but actually Survivor. Wow, my childhood memories could have done without this trauma.

Whatever puts you in the zone to work — just make sure you aren’t hindering others around you.

Most User Friendly: WordPress or Joomla?

Let the debate begin… Which is the most user friendly platform? WordPress or Joomla?

Firstly, yes we know there are so many other options to choose from that may have certain advantages over both platforms… but the most common question we receive from new webmasters is: Which is the most user friendly CMS platform for a novice developer out of WordPress or Joomla?

We can only assume one position on this question: it depends.

Sorry if this is a little vague for anyone wanting to know the exact answer – but it really does depend on the application needed. For some sites, you are going to have an easier time using a WordPress theme and other times Joomla is a no-brainer.

What you choose really depends on your application and needs to be an important consideration for any new build. Although this website is built on the WordPress platform, we have hosting established for a number of Joomla and Magento sites running custom eCommerce applications. They all work better on our SSD hosting environment.

What is your top pick? One of these two or a different alternative? Please submit your comments below to start the discussion. Also, check out our facebook page here.
