The Store n Go had a quirky performance profile. For its price the drive shone in the CrystalDiskMark and ATTO tests but the AS-SSD real world speed test revealed that the drive was less able to both read and write at the same time. It might be best to avoid this drive if you plan to run applications or host an operating system. Our tests showed the drive outperforming Verbatim's claimed write speed by a factor of three, an unusual result. There are several versions of this drive going by the same name, some with an LED, some without and all with vastly varying speed profiles. Our test drive performed at the top end of the speed range we have seen. Overall, given the low price but inconsistent results, we consider this drive average at best and a somewhat risky purchase.  [Oct '13 USBFlashPro]

The Supersonic Xpress has a great physical form, the innovative retractable design features a spring loaded back which snaps into place very satisfyingly, it's tempting to pop it in and out for no particular reason. In terms of performance the Xpress is below average across the board with the exception of an outstandingly high 4K read score of 14.2 MB/s. From a value perspective this drive is near the bottom of the pack, it has below average performance and is currently retailing at an above average price. [Jun '12 USBFlashPro]
