A few months ago, I wrote a quick note about the Fusion-IO ioDrive. I said at the time:
80GB. $2400. 9 watts. 120,000 IOPS. 600MB/second random writes.Now I've got one for testing at my day job.
If this thing really delivers, it's a silver bullet for mid-scale databases. I want a silver bullet for mid-scale databases.
But can it really do 120,000 IOPS? Well, let's start with a 40GB random-write test. Single threaded, with no optimisations. And the envelope please...
random-write: (groupid=0, jobs=1): err= 0: pid=4626Whoa.
write: io=40,000MiB, bw=271MiB/s, iops=67,869, runt=150877msec
clat (usec): min=4, max=37,767, avg=12.32, stdev=44.36
bw (KiB/s) : min= 0, max=335749, per=99.90%, avg=277725.87, stdev=25273.96
cpu : usr=15.47%, sys=83.93%, ctx=5153, majf=1, minf=2152631
Okay, that's not 120,000. But 67,000 without any tweaking at all is amazing. I have the same test running on a standard SATA drive; it's sustaining a little over 300 IOPS, making the ioDrive easily 200 times faster.
I've got a lot more testing to do, but so far it looks like the ioDrive really delivers the goods.
Unfortunately, since June the Aussie dollar has drifted south by about 30% and I can no longer afford the card, at least not short of working every Sunday for two months. But there are some cheaper, lower-end drives showing up, and I'd be very happy with a quarter of the ioDrive's performance for a quarter of the price.
That would be something. And using 9 watts !

That alone is a plus.
