The benchmark scores for the SanDisk Extreme were stunning. Until now every flash drive we have tested has shown a serious weakness in the area of 4K random writes. The SanDisk Extreme achieved a 4K random write speed of 2.1 MB/s which was over three times faster than the best of the rest, unfortunately we were unable to get consistent measurements but 2.1 MB/s was towards at the lower end of the range (10.8 MB/s - 1.71 MB/s) we observed. We suspect the inconsistency relates to the way the controller batches page cleanup. The other benchmark observations were all consistent and to date this drive has the highest sequential read we have seen on a 16GB flash drive. The SanDisk Extreme has not been released in the UK. Our test unit had to be shipped from Hong Kong where we were able to purchase it at at an extremely reasonable price. We will update the price if/when the drive becomes officially available in the UK ... [Jul '12 USBFlashPro]

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]
