Why Solid State Drives should be considered for your Business IT

Solid State Drives

I'm sure everyone has heard of Solid State Drives or "SSDs" as they are now referred to, but do you really know the marked differences between SSDs and a standard mechanical disk drive. What if disks didn't spin? What if there were a way to create rewriteable storage in such a way that there were no platters, no spindles and no heads? You'd have a solid state disk with no moving parts. Solid state disks (SSDs) are all the rage for server vendors, SAN vendors, and appliance manufacturers. Why? Not because they're cheap -- they're not. SSDs have several advantages over traditional mechanical (spinning) disks. Here are some of the most frequently quoted advantages of SSDs over mechanical disks

1. Life Expectancy

SSDs may be expensive, but they're well worth the price when you consider their advantages. Mechanical drives have an average life expectancy of three to five years. Many fail long before the lower end of the average, and few last beyond the upper end of the average. At three years, you should seriously consider a refresh. At five years, you're pushing it. Alternatively, SSDs have life expectancies reaching into decades. Expect your SSDs to last two significantly longer than mechanical drives

2. Performance

Since SSDs have no moving parts, their access and seek times are many times faster than those of their mechanical counterparts. Mechanical drives have high-burst speeds, but their sustained speeds are unimpressive by SSD standards. However, write performance is not significantly different between the two technologies. Therefore, read and access performance-heavy workloads will benefit from SSDs, while workloads that are write-intensive would do as well with the less-expensive standard disks

3. Shock Resistance

SSDs are a good choice for mobile systems due to their resistance to drops, bumps and g-forces. Movement can have devastating effects on mechanical drives, especially during write events. SSDs, again having no moving parts, aren't affected by mobility and are well-suited to such physical abuse. SSDs can withstand up to 1,500 g during operation or 25 times that of a standard drive. It is for this reason That Connect-IT has moved to SSDs in the majority of the business grade laptops we provide to our customers.

4. Power Loss Protection

Enterprise-class SSDs rely on power failure circuitry to monitor voltage changes. If the voltage drops below the threshold, a secondary voltage hold-up circuit ensures that the drive has sufficient power to save any pending writes to disk. A supercapacitor, a discrete bank of capacitors or a battery acts as this secondary voltage hold-up circuit.

5. Noise

If you've ever stood in a data center, you probably noticed the very high noise level. Imagine a data center filled with SSDs instead of standard drives. Other than the sound of system fans, cabinet fans and the central air conditioning system, the data center becomes significantly quieter. I don't I'm alone in wanting a "Quieter" computer or laptop. More and more of us are using laptops with a docking station right on our desk. Who wants to listen to that all day?
