Iometer database and workstation perf
We mentioned that the F100 drive straddles the consumer and enterprise spaces. The latter requires excellent responsiveness when under varying loads. Here's how Iometer pans out.
The first test runs the database pattern - 8KB transfers, 67 per cent read, 33 per cent write ratio, and 100 per cent random accesses - with a queue depth of two. A low QD intimates a very light load.
Scorching performance here, providing over 2x the performance of the next-best SSD.
Now the load is increased to 32 outstanding I/Os (queue depth), indicating moderate/heavy load. Drives that can efficiently queue requests see a huge leap in performance.
Still top-of-the-class scores here.
The workstation pattern - 8KB transfers, 80 per cent read, 20 per cent write, and 80 per cent random accesses - shows the same three drives battling it out for top spot with a queue depth of two.
Again, a super-fast IOPS rate here.
Scaling nicely to a queue depth of 32.
Interestingly, backing up CrystalDiskMark's findings, running Iometer with a 4K random write setting (QD32) leads to a 70MB/s throughput, which translates to 17,900 IOPS - way above what SandForce is claiming for the SF-1200's vital stats.
