Performance in FC-Test 1.0

FC-Test will help us examine the flash drives under real-life conditions. The program writes and reads a few file-sets and measures the time it takes to perform each operation. This helps calculate the speed of the drive and see how it depends on the number and size of the processed files. We use three file-sets that differ in the size (1, 10 and 100MB) and number (1, 10, and 100) of files included. Practice suggests that a 100MB file is large enough to reveal the maximum performance of a USB flash drive and using a larger file doesn’t affect the results much.

There are three leaders at writing 1MB files: Super Talent 200x, OCZ Rally 2 Turbo and OCZ ATV Turbo. Alas, most of the drives could not reach a speed of 10MBps even. The RiData Yego EZdrive has a fantastically low speed.

The speeds vary less when the drives read 1MB files, yet the leader is 2.5 times as fast as the slowest drive. The top four includes the Super Talent 200x, Patriot Xporter, Lexar JumpDrive and A-Data C702. And there are five more drives that deliver a write speed higher than 30MBps.

About half of the drives are slower than 20MBps. On the other hand, none of them is slower than 10MBps.

Each drive has a higher write speed when the size of the files is increased to 10 megabytes, but there are no changes in the standings. The RiData Yego EZdrive is again the slowest of all, with an almost tenfold gap from the leaders.

The size of the files doesn’t affect the read speed much, but we see every drive speed up a little. We’ve got the same leaders and losers, though.

Every drive accelerates a little more when writing a single 100MB file, but the standings are overall the same. The Super Talent 200x is in the lead, followed by two Turbo series drives from OCZ. The SanDisk Ducati, Buffalo RUF2-S, Kingston DT Secure and Patriot Xporter are somewhat slower than the leaders. The RiData Yego EZdrive can’t leave its last place although it is very close to the A-Data C701.

There are but minor changes in the leading group and no changes at all among the three slowest devices.
