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.

Our tests of the 60GB G.Skill Phoenix Pro SSD were each consistent, but only the maximum speeds were charted below. Sequential tests on the Phoenix Pro SSD produced a maximum read speed of 203.8 MB/s, while the write speed was a mere 58.34 MB/s (although 100.4 MB/s was reported in one test). The sequential file transfer speeds have traditionally been low with this benchmark tool, especially for SandForce controllers, which is why we will concentrate on the operational IOPS performance for this section.

CrystalDiskMark 3.0 reported 512K results of 194.9 MB/s read and only 55.52 MB/s write performance (99.55 MB/s was reported in one test). 4K tests produced 22.02 read and 55.65 write performance. 4KB queue depth 32 IOPS is one area where SandForce-based SSDs truly excel, and performance for the 60GB G.Skill Phoenix Pro trails the other SandForce SSDs.

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:

Hello, I have noticed that in the "Iometer IOPS Performance" you already have the performance of the Vertex 2 in the graphics, I guess this is a preview? ;-)

Also if it is not asking too much could you also test in parallel the Vertex LE (Limited Edition)?
This because there are many confusion around the web and although they seems to perform similar (Vertex 2 and Vertex LE), it would be nice for the customer to understand which one of these two is the fastest!
I trust Benchmarkreviews!!
thanks!

The Vertex-2 review is coming in the next few days; I just happened to be making charts and already had the results for this test. The Vertex LE will not be tested at this time because we do not have a sample. I assure you though, nobody could ever tell the difference in performance without a synthetic benchmark.
