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...

    Oh yeah, thanks for the max latency figures. They're very useful.

    The G2's max of 900ms is quite a long time. Nearly a second! What are the max latencies for say a velociraptor in similar tests? I know the theoretical figures would be based on seek time + RPM but often theory is different from practice.

    I find it interesting that the Crucial RealSSD C300 does worse than the Intel SSD 510 in the "Anand Storage Bench 2011- Heavy Workload" despite getting better numbers in the random and sequential tests. Any idea why this would be so? Poorer max latency?

    Poorer sequential performance I guess. The C300 (which I just got) is very fast, but the sequential perf of the 510 is simply better, which impacts a lot of the sequential portion of the workload test. Random performance in typical desktop models has reached somewhat of a plateau, particularly since most applications currently out there are optimized for the dog-slow random performance of consumer hard drives.

    About reliability/compatibility: have you tested this drive in the new Sandy Bridge Macbook Pro? Any issues?
  • davepermen - Monday, March 7, 2011 - link

    Interestingly, one of THE main performance cases is when you need to quickly write lots of stuff, like in video editing. And there, all data is at least partially compressed, so i guess there the intel will be in a better place.

    Intel is going to have to price this thing cheaper than the Vertex 3, or any other new Sandforce SSD for that matter. They can't use performance as a selling point. I'm sure the new SF controller will offer good stability. Unless you're an Intel fanboy I don't see any reason to get the 510 over the Vertex 3, unless they price it much lower.

    This is an Atom alright!

    I think the conclusion, although critical in places was overall mild. “It looks like we may have hit the upper limit of what we need from 4KB random write performance”… Yeah, in the consumer/budget space. But what consumer/budget computer user would buy a 250GB SSD. I’ve managed to convince a few of my clients to go with an “expensive upgrade” and in the end they’ve been extremely happy… In those cases I’ve only installed 64GB drives.

    At the moment SSDs are NOT mainstream and it’s mostly the enthusiast and pro crowd that will be buying consumer grade SSDs. I’ll be using my SSD for VMs for testing and studying and I do a lot of heavy random IO operations.

    For a drive as big and as expensive as the 250GB 510, I expect much better across-the-board performance.

    Hi, the article states "~900ms write operation, the 510 keeps the worst case latency to below 400ms. The Vertex 3 by comparison has a max write latency of anywhere from 60ms - 350ms"

    microseconds are usually abbreviated us, where the u has a funny tail on it. (the u is greek for something)
    ms usually means milliseconds. I usually type 'mics' when on the keyboard and reserve the funny u for when handwriting. example, a good SSD write takes less then 100 mics.

    saying something is around 900 ms means it takes about a second.
  • epicsnackus - Wednesday, March 2, 2011 - link

    The article is correct, the numbers are really in milliseconds. The microsecond numbers you're thinking of are 1) best case, and 2) usually reads
  • Chloiber - Wednesday, March 2, 2011 - link

    "Write speed with fully incompressible data is easily a victory for the SF-2200 based OCZ Vertex 3."

    I think you meant fully compressible?

    Fixed! Thank you :)

    Take care,
