Fusion-io vs Intel X25-M SSD RAID, Grudge Match Review
As we noted in a previous SSD round-up article, though IOMeter is clearly thought of as a well respected industry standard drive benchmark, we're not completely comfortable with it for testing SSDs, as well as comparing their performance to standard hard drives. The fact of the matter is, though our actual results with IOMeter appear to be accurate, it is debatable whether or not certain access patterns, as they are presented to and measured on an SSD, actually provide a valid example of real world performance, at least for the average end user. That said, we do think Iometer is a solid gauge for relative available bandwidth with a given storage solution. Regardless, here's a sampling of our test runs with Iometer version 2006.07.27 on our SSD RAID pack versus the ioDrive.
For the Fusion-io ioDrive, as we tax it with a larger number of requests, its performance curve just shoots for the moon. Though we didn't plot it here, if we turned up the number of outstanding IOs to 2048, the drive actually exceeded its 100K IOPS theoretical top-end performance (103K IOPS to be exact) - which we will of course admit is just an insane amount of available bandwidth.
