USB drive Spark 32GB write / read speed benchmark

Spark 32GB USB 3.0 Flash Drive (PSF32GSPK3USB) is great size, nice design, but impractical chain and disappointing write speed


In Ubuntu 12.04 x64 Precise on HP EliteBook 8540w USB 3 enabled, bench-marking software from Disk Utility.


In Windows 7 x64 HP EliteBook 8560w USB 3 enabled, bench-marking software USBDeview from Nirsoft.

In reality on copying number of large media files on NTFS 64k block size it performs just over 9 MB/s, I am copying from a SSD drive with nothing just copying in active windows.


I am very disappointed, it is second-class performance, some 5 years old USB sticks do better than that, specification on manufacturers website is some theoretical read speed.

USB drive is supplied with a small chain, my advice is to replace it as soon as possible, it is soft and loose.
