SSD Testing Disclaimer:

Because of the wear-leveling algorithms used in SSDs, performance is actually pretty hard to nail down.  It is for this reason also that drive performance can vary so much from one review to the next.  Some sites go to extreme measures to show the maximum performance possible after they use utilities to restore the drive to pristine performance levels, but that isn't accurate in the real world.  We've tried to get a balance of the pristine and the dirty drive here at BCCHardware and have used this drive extensively in our test systems both running Windows 7 x64 Ultimate.  We feel that our results are as reproducible as possible, and while no software can accurately measure SSD performance in a perfectly fair fashion, we've done our best to keep the results accurate as possible.  We've used synthetic benchmark tools such as HDTach, Everest, CrystalDisk Mark and others that are indicators of real-world performance.

Performance - AS SSD:

As we kick off our benchmarks, we're going to introduce a new benchmark to our SSD test suite.  As such, we don't have much in the way of comparison, but we do have a comparison with the RevoDrive X2 and the original Vertex 3 that we've looked at recently.  Overall, the performance of the drive is pretty impressive, but according to AS SSD, it does fall short of its rated speed.  This time around we are looking at IOPS with AS SSD and will cover actual MB/sec transfer rates with ATTO in a little bit.  You can see below, that the IOPS in our tests on the X58 test system that fully supports SATA 3 (6Gbps), shows poorer performance than the rated specs.

Performance - ATTO:

ATTO is not an indicator of real-world performance, but it shows how fast the drive can read and write data using different sized files.  We've included results from the 128GB Patriot Torqx, Crucial RealSSD C300 and OCZ RevoDrive X2 SSD.  A few different NAND, DRAM and controller options are represented below.  Of course, we expect the RevoDrive to take the cake - and it does - in terms of overall speed, but when it comes to smaller files, the new Vertex 3 takes the lead up to 16KB files.

You don't have to study the charts very long before you see that the OCZ Vertex 3 holds its own when it comes to read speeds.  Other than the RevoDrive, the Vertex 3 LP keeps up with the standard Vertex 3 and trades places back and forth when it comes to top performance.  Even though the drive features different NAND, and has a smaller stature, it still performs well.  Overall, ATTO shows off what this drive is capable of - even though it falls a bit short of the rated speeds.
