AS-SSD Benchmark

Alex Schepeljanski of Alex Intelligent Software develops the free AS SSD Benchmark utility for testing storage devices. The AS SSD Benchmark tests sequential read and write speeds, input/output operational performance, and response times. Because this software receives frequent updates, Benchmark Reviews recommends that you compare results only within the same version family.

Beginning with sequential read and write performance, the 120GB OCZ Agility 2 Extended Solid State Drive produced 207.85 MB/s read speed, and 134.59 MB/s write performance. 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.

Single-threaded 4K IOPS performance delivers 21.28 MB/s read and 62.80 MB/s write, which is among the highest results we've recorded. Similarly, the 64-thread 4K reads recorded 125.47 MB/s while write performance was 94.45 MB/s... both earning the OCZ Agility 2 a spot among the top performance results in our charts.

Displayed in the chart below, the 64-thread 4KB IOPS performance results for several enthusiast-level storage products helps to illustrate which products offer the best operational input/output under load:

In the next section, Benchmark Reviews tests transfer rates using ATTO Disk Benchmark.

A really good thorough review of this product and a testimonial to the speed of the Sandforce processor

Nice!! Now we are just waiting for the Vertex LE performance test, that many websites claims as the best SSD on the market...but I only trust benchmarkreviews! :-)

# Vertex LE = Limited EditionOlin Coles 2010-08-01 11:19
Sorry, but there are no plans to review the Vertex LE. This is because the Vertex LE is essentially the Vertex 2, released at a time when the 50K IOPS firmware was licensed for premium. Now there are at least a dozen different companies with 50K SandForce SSDs.

I've just upgraded yet again from my first SSD a little over a year ago, to a larger, newer, more refined model, twice the 32Gb I started with, and have added Trim support as well (my first was a JMicron controlled, hair of stutter, 32Gb Patriot; now a Kingston 64Gb V-series). I caught both on "sale" as they were older models at the time of purchase, Sandforce no doubt forcing the liquidation of inventories. The Patriot purchase was for $99 for 32Gb, the Kingston at $99 for 64Gb, basically $1.34/Gb. Although this is just me staying a generation or two behind the bleeding edge, I find it a very adoptable price point and it affords me the upgrade path for multiple home systems simultaneously. All in all, I think your extrapolation of the future pricing of SSDs is coming sooner rather than later and any enthusiast can make the jump into SSDs before the next year is out. As you've stated several times in several ways, it is the single most satisfying upgrade one may do to a PC.

# Lagging Edge....BruceBruce 2010-07-30 16:56
I'm with you on your acquisition strategy... The $100-$150 price point has been very fertile ground if you are willing to wait for Newegg ShellShocker deals and tech that is ~ 6 months old. Once I had my first taste of SSD performance, I knew there was no way I was going back to mechanical drives.

"As you've stated several times in several ways, it is the single most satisfying upgrade one may do to a PC."

I'm so glad that people are finally coming to understand where speed comes from for most computer-related tasks.

I have one of these in the 60GB size and it was a real shot in the arm for the system's performance. I install everything else to the data drives, but run the 64 bit win-7 system on the SSD. I'm very satisfied with it's performance characteristics. As the prices do come down, I'll buy them for all of the other PC's in the house.

do you test these drives with them as the operating system drive? or are they separate data drives?

# RE: wondering somethingOlin Coles 2010-08-09 12:07
All storage devices are tested as a secondary drive. It would be impossible to test them with the O/S or any partition, because some tests erase data or require no partition.

# TRIM support... confused!Frammel 2010-08-23 21:22
I have been looking ALL over for a straight-forward answer to this question and I can't find one, can only find info hinting towards this. The OCZ Agi II drives with their 1.11 firmware say they support TRIM. I see people write that it's 'native' and it's 'included' and it's 'available', etc... but is it an automatic function or should I be scrambling for a tool that allows me to manually run TRIM? I'm currently running Win 7 Ultimate 64-bit. Absolutely worth-it drive, I don't want to miss out on an ounce of performance because of this!

# RE: TRIM support... confused!Olin Coles 2010-08-23 21:30
You haven't found an answer because it's a relatively common-sense question that people don't spend time writing about. All SandForce-driven SSDs include TRIM support, similar to the previous generation of Indilinx SSDs. This is like saying your car is capable of running on water... all you have to do is supply the water. The Windows 7 O/S is that water, and activates TRIM commands automatically in the background.

# Trim Built In to W7BruceBruce 2010-08-23 21:28
It's the default setup for Win 7. It works in the background. I know...I'd rather "see" it working, too. But it IS working.
