Intel SSD 910 PCI Express SSD Performance Review

23 thumbs up

As we've noted in our previous SSD coverage, though IOMeter is clearly a well-respected industry standard drive benchmark, we're not completely comfortable with it for testing SSDs. The fact of the matter is, though our actual results with IOMeter appear to scale properly, 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 for the average end user. That said, we do think IOMeter is a gauge for relative available bandwidth with a given storage solution.  In addition there are certain higher-end workloads you can invoke on a drive with IOMeter, that you really can't with any other benchmark tool available currently.

In the following tables, we're showing two sets of access patterns; our Workstation pattern, with an 8K transfer size, 80% reads (20% writes) and 80% random (20% sequential) access and our Database access pattern of 4K transfers, 67% reads (34% writes) and 100% random access.


As we saw in a few of the previous benchmarks, random read performance is not the SSD 910's strong suit.  It's only as the IO queue depth begins to scale that Intel's solution starts to join the hunt.

Our database access pattern showed much of the same performance grouping as we saw in the Workstation setup.  However, with a higher write workload and smaller 4K transfers, the Intel SSD 910 begins to show signs of strength.  Still Fusion-io's ioDrive and OCZ's Z-Drive far and away lead the pack in this test pattern.


The workload you see represented in this graph has become a bit "industry standard" as of late, though we'd offer that it still should be taken with a grain of salt.  Again, what we're looking at here is one set access pattern that is concurrently sprayed across the drive volume by IOMeter until the drive reaches its saturation point.  In this IOMeter run, we should note that drives were formatted, blank and were allowed to sit idle for several hours before invoking a test, so that each drive's maintenance algorithms had a chance to maximize performance.

This access condition is clearly where Intel's SSD 910 shines.  We didn't have access to the OCZ Z-Drive R4 here unfortunately but we'd offer it would likely be a close race.  With a full write-only workload, small transfer sizes and a high queue depth, the Intel SSD 910 actually takes the top spot here by a comfortable ~ 15% margin.

Wow all i can is wow. But yeah for that price i would see no reason even for a hardcore tech enthusiast to purchase one but if you had one man the things you could do(run a data center i guess).

Like the article ends with, can't wait for this to work down to the prosumer level. With the advances in CPU, GPU computing and SSD the future looks bright.

on tha refrence pcb these daughter boards are on could you put their i/o on tha reverse side as well dont see pics of other side ..if so couldnt you do a double sided one ..and for these $$ it would have to be a 3.0pci lane otherwise i just dont see tha point although a cachedrive off one of these would be great @14pt lifetime

You hit the nail on the head there, MSpitler. At some point you reach the limits of a PCIe X8 Gen 2 slot's bandwidth, though this cards doesn't quite hit that. Heck, go to a X16 card and you'd have plenty, though a bit cumbersome maybe.

Though I would never buy this because I personally have no use of it, I can see where these come in handy. It's also nice to see where our technology in storage space will end up.

Finally, Intel is jumping into the fray. This should create some much needed competition in this space. Will only benefit those of us prosumers.
