Enterprise Workload Performance

Toshiba's $7000+ 400 GB SSD: SAS 6Gb/s, SLC Flash, And Big Endurance

Our last batch of synthetic tests subjects each SSD to the standard database, file server, and Web server profiles in Iometer.

Our Iometer database workload (also categorized as transaction processing) involves purely random I/O. Its profile consists of 67% reads and 33% writes using 8 KB transfers.

Despite the Toshiba drive's strong random performance, Intel's SSD 520 manages to jump into a compelling lead thanks to the compressibility of our data. Even if you hit it with incompressible information instead (the blue bar labeled Random), it still matches pace with Micron's P300, though. Interestingly, the MK4001GRZB falls behind, stymied by the mixed workload.

The file server test, which is also dominated by random I/O, is even more biased toward read operations. However, the gap separating Intel's SSD 520, Micron's P300, and Toshiba's MK4001GRZB is smaller.

The Web server profile consists completely of random reads. If you remember back to the first chart on page five, where Toshiba's drive absolutely dominated, we quickly come to understand why the MK4001GRZB jumps in front here as well. This is clearly an environment where Toshiba's enterprise SSD operates at its peak potential.
