USB 3.0 RAIDDrive Features

Our USB 3.0 RAIDDrive is unquestionably one of the fastest drives on the market today; even faster than the fastest internal SSD. Available in 32, 64 and 128GB capacities, our USB 3.0 RAIDDrive is actually two SSDs combined together in RAID 0 array. This means that we are able to pull data from two drives simultaneously. Supported by a caching system, each SSD controller is able to support true performance across the entire performance curve.

Far more than a flash drive, the USB 3.0 RAIDDrive is two multi-channel SSD drives cleverly combined into a RAID array. Packaged in an ultra-small form factor, this SSD RAID array is slightly larger than a standard flash drive yet able to achieve data transfers of over 300MBps; that's incredible performance for a drive of any size. The USB 3.0 RAIDDrive is not only fast, it is also the only RAID array that you can fit in your pocket.

- USB 3.0 Interface for unprecedented speed
- Compatible with USB 3.0 & USB 2.0 standards*
- Highly Reliable MLC NAND Flash

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.

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 ???
