AS-SSD Benchmark Test Results

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.

This purpose of this section is to illustrate sequential file transfer speeds and demonstrate operational IOPS performance using AS-SSD Benchmark. For reference, we first tested the OCZ Rally-2 Turbo USB-2.0 flash drive which produced 27.9 MB/s read and 24.8 MB/s write speeds. With the Super Talent RAIDDrive ST3U64SRK attached to the Intel ICH10 USB-2.0 controller, this flash drive produced 33.2 MB/s read and 26.8 MB/s write speeds.

Stepping up to SuperSpeed USB-3.0 using the NEC-D720200F1 controller, the Super Talent RAIDDrive produced an impressive 156.3 MB/s read and 72.7 MB/s write speeds. These results are getting closer to the manufacturers suggested maximum speeds of 320/180 MB/s, but we haven't applied Super Talent's RAIDDrive RAID-0 software yet.

Once the 'STT USB Composite Device' and 'STT USB 3.0 Miniport' software has been installed, the Super Talent USB-3.0 RAIDDrive operates in a RAID-0 twin SSD array. AS-SSD produced 225.6 MB/s read and 103 MB/s write, both of which are impressive, but not quite reaching the advertised 320/180 MB/s read and write speeds.

AS-SSD Benchmark is great for comparing 4K IOPS results tested with 64 concurrent threads, but it's good to have a second opinion for basic speed measurements. To approach this from a different angle, we've included ATTO Disk Benchmark results in the next section.

You took the wrong motherboard for testing - it would not support more than 240MB/s, as NEC chip is using only 250GB/s PCIe x1 link.

Try it with ASUS add-on combo on the board that has southbridge PCIe x4 slot - only then you can compare real and declared productivity.

I'm not entirely certain this is the case. The NEC controller ties into the PCIe 2.0 lanes from my research, which means that there is at least 5Gb/s bandwidth. Regardless, the 320/180 MB/s that Super Talent suggests was nowhere close to the 239/106 MB/s we received. AS-SSD and ATTO both had low write-to performance, which was a far cry from the bandwidth restriction you suggest.

NEC USB3.0 chip on this mobo connected directly to X58 chip, so it gets one PCI-E 2.0 lane. You may check it by yourself, just view user's guide to this mobo.

A bit earlier version of the article stated that the testbench was GA-P55A-UD7. And that make a big difference.

You need to get more sleep. :p This article hasn't been modified or edited. The original test motherboard was the GA-X58A-UD7. As far as I know, Benchmark Reviews has never received/tested the GA-P55A-UD7.

At any rate, I'm glad we got that sorted out.

Sorry,then

Then there is still much to improove to get full USB 3.0 speed.

I think this is a good start, but it seems that the new SuperSpeed USB-3.0 standard is too new for the industry. We probably have a few more years before USB 3 flash drives become widely available and used.

Just wondering if you used the ST USB 3 RAIDDrive drivers ???
