I Know What I Want For Christmas

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.

If this thing really delivers, it's a silver bullet for mid-scale databases.  I want a silver bullet for mid-scale databases.

Now I've got one for testing at my day job.

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=4626
  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

Whoa.

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.
