Can The Flash-Based ioDrive Redefine Storage Performance?

Fileserver, Workstation Performance

Look at this: the ioDrive reaches more than 10,000 I/O operations per second on file server load. If you switch to improved write performance, this will more than double the results at high command queue depths, where the controller can optimize operations and distribute writes across the two sections of the drive. Maximum write performance does not introduce much more performance, but compared to the single and RAID 0 flash SSDs, the increase is still significant.

We took the average throughput created by the ioDrive during the fileserver IOMeter benchmark run. The flash SSDs by Mtron and Samsung stay well below 10 MB/s, while Fusion-io reaches 125 MB/s at full capacity, and even better average performance when switched to improved write performance mode.

The results are similar in the workstation benchmark pattern. The maximum number of I/O operations per second increases even more at improved write performance mode. But standard mode (maximum capacity) still yields 12,000 to 16,500 IOps.

Again, we put the average throughput for the workstation IOMeter benchmark run into a chart. The results are even more impressive—in favor of the ioDrive.
