CrystalDiskMark 3.0 Tests

CrystalDiskMark 3.0 is a file transfer and operational bandwidth benchmark tool from Crystal Dew World that offers performance transfer speed results using sequential, 512KB random, and 4KB random samples. For our test results chart below, the 4KB 32-Queue Depth read and write performance was measured using a 1000MB space. CrystalDiskMark requires that an active partition be set on the drive being tested, and all drives are formatted with NTFS on the Intel ICH10 controller set to AHCI-mode. Benchmark Reviews uses CrystalDiskMark to illustrate operational IOPS performance with multiple threads. In addition to our other tests, this benchmark allows us to determine operational bandwidth under heavy load.

Sequential tests on the OCZ RevoDrive X2 SSD produced a maximum read speed of 680.9 MB/s, while the write speed was 279.0 MB/s. The sequential file transfer speeds have traditionally been low with this benchmark tool because of uncompressed data, especially in regard to SandForce controllers, which is why we concentrate on the operational IOPS performance for this section.

CrystalDiskMark 3.0 reported 512K results of 580.3 MB/s read and 279.1 MB/s write performance. 4K tests produced 28.32 read and 77.56 write performance. 4KB queue depth 32 IOPS is one area where SandForce-driven SSDs truly excel, and performance for the 240GB OCZ RevoDrive X2 leads the other SandForce SSDs with 291.2 MBps read and 258.1 MBps write.

Displayed in the chart below, the maximum 4KB queue depth 32 IOPS performance results for several enthusiast-level storage products illustrate which products offer the best operation under load:

Compared with two separate SandForce SF-1200 SSDs in RAID-0 that produce 231/150 MBps maximum IOPS at 4KB queue depth 32, both the standard OCZ RevoDrive and RevoDrive X2 exceed read performance and heavily outperforms in write operations.

This thing really rocks. The 'real world' experience using a computer with one of these things inside of it must be sweet indeed. Can't afford one of them and may never be able to. But it's good to see that they're out there.

Any SSD will make you notice a super-boost in real world experience against HDDs. I'm sure you'll not notice a difference between controllers, but I'm not sure if the RevoDrive X2 could make THE difference.

Bloody hell that's fast, you sure as hell pay for it though...

I'm yet to upgrade to any SSD yet unfortunately, still waiting for the technology to move on a bit / become more affordable.

This by far is the best performers on the market.
I'm debating weather to get an extra c300 (256 gig) for raid 0,(total 500gigs >700 mb/sec read/500 rights) extra $525
Vs Revodrive x2 256gig one, extra $699.
(aren't the Sandforce 2500, 2600 controllers out soon as well?)

You can expect the next generation of SandForce products in Q1 2011, but not sooner. This particular product, while being extremely fast, lacks TRIM support because of the RAID controller. In my opinion, you shouldn't buy an SSD without TRIM support. In this case however, there recovery time wouldn't be an issue unless you did constant fills.

Although this is an old post, I felt the need to clarify.
TRIM is not needed for Revodrive X2 due to the garbage collecting algorithms built into SandForce. TRIM is a sloppy patch job on a problem that should of never existed and on any good drive will not be needed.

WOW! Those things are ridiculously expensive!
