The Intel SSD 510 Review

Final Words

The first time Intel told me it would be using a 3rd party controller in one of its upcoming SSDs I bit my tongue. Intel tried to justify the decision but all I heard in my head was that Intel was bowing out of the high end race, that Elmcrest was a copout. I have to admit I was wrong. I assumed that Elmcrest wouldn't be even remotely competitive. In reality, the Intel SSD 510 may not be the fastest SATA SSD we've ever tested, but it comes very close. Overall performance is within striking distance of the Vertex 3 and depending on the test, performance can actually be a little higher than the clever competitor. Note that I've only tested the 250GB drive. Intel's 120GB SSD 510 should be measurably slower.

The 510 is most interesting over a 6Gbps interface. Connected to a 3Gbps interface the drive is quick, but fails to distance itself from the high end drives of last year. This is the same conclusion I came to when I previewed the Vertex 3. These next-generation SSDs not only use 6Gbps SATA, they really need it.

My biggest complaints about the 510 actually aren't about Intel's use of a 3rd party controller, instead they are about the drive's lackluster random read performance. In a horrible bout of irony Intel fixed its sequential performance and moved backwards in the random department. Random read performance, as it turns out, has a pretty major impact in the real world.

Random write performance is also pretty low by today's standards, however the impact on most of our real world performance tests is minimal. It looks like we may have hit the upper limit of what we need from 4KB random write performance (at least given current workloads).

Sequential performance is easily competitive with the Vertex 3, and when presented with incompressible data the Intel SSD 510 is easily faster.

Overall OCZ's Vertex 3 is faster, however the margin of victory isn't always significant. Intel would argue that its drive is better tested and less likely to fail. Whether this is true remains to be seen, but history does count for something.

As always, it'll be months before we have a good idea of compatibility, reliability and any long term issues. In typical AnandTech fashion I've already deployed the Intel SSD 510 in a primary use system. The big advantage Intel has today is that its drive is currently available and it seems to work. The performance is good and close enough to the Vertex 3 that if the drive does end up being more reliable Intel could have a winner on its hands.

At the same time, OCZ has been investing tremendously in improving manufacturing quality and validation testing. If the Vertex 3 can launch without any major firmware bugs, reliability or manufacturing issues, Intel's SSD 510 may not have a leg to stand on.

Then we have the other Marvell based designs from Corsair and Crucial/Micron. The 2011 SSD market is just starting to heat up...
