Solid State Drives:
Incredible speed + mind-blowing performance = WOW.
We love Solid State Drives, also known as SSDs. They are flash-based storage devices. Once you try one, or an entire RAID set of them, there’s just no going back to Hard Drive Disks! What SSDs lack in raw storage space they more than make up for in the following areas.
Speed, speed, speed.
These drives are off the charts when it comes to read and write times – especially reads (kickin’ database server, anyone?) They can manage 110 MB/s in effective reads and access time 0.1ms. With no “spin-up” time required, applications launch almost instantly, boot times are drastically reduced, and any sort of data-intensive application gains an immediate and noticeable performance boost.
Get your SSDs now – there is a significant risk that the FDA will soon classify them as “addiction-inducing” devices.
The graph below demonstrates the performance of a traditional Western Digital 160GB hard drive. The blue line is the transfer rate, where the higher the number, the better. The yellow dots are the access time, where the lower number is better. As you can see in the graph below, performance degrades over the 4 minute test. The transfer rate decreases while the access time increases. This is true of all Hard Disk Drives.

The next graph below is our new Intel X25 80GB Solid State Drive (SSD). Notice that the performance NEVER degrades, the Data Transfer Rate stays steady with an average of 218.5 MB/s vs 53.3 MB/s, and the seek time is so fast that you can’t even see the yellow dots at the bottom of the graph unless you squint and try to visualize them.
The WD 160GB HDD takes 13.0ms to access data, whereas the SSD takes virtually 0.0! That is an increase of over 13,000%! It is almost like adding 80GB of RAM to your server because a Solid State Drive is a “Flash Drive,” which is essentially RAM instead of a spinning disk.
A quick review of the comparison chart below will show you that the average read speed is 400% faster. Disk I/O no longer has to be your bottleneck.

Efficiency
Not only are SSDs completely silent, but they have far lower power requirements than standard hard drives. This makes data center operators very happy.
Reliability
These drives are absolutely ideal for mobile applications like laptops, but they work incredibly well in servers, too. Anyone who has experienced a hard drive crash will appreciate the security that accompanies a solid state drive that has no moving parts to break or wear out.
Less chance of mechanical failure = secure data = happy customer = happy CariNet.
Want SSD? We’ve got it. You’ll like it. We guarantee that!
