Mushkin Enhanced Ventura 240GB USB 3.0 Solid State Drive
On paper, this is pretty much the fastest flash drive you can find with read/write speeds up to 450 MB/s and 445 MB/s which is hard to beat. In testing however, this model typically falls behind the SanDisk Extreme, though it comes quite close and still represents an excellent overall value. With that in mind, it has a USB 3.0 interface and offers more storage than a lot of other flash drives that deliver such excellent performance.
This is currently the largest model available with two smaller ones that have 120GB and 60GB of storage each, plus there’s another model coming soon that will have 480GB of storage if you need more space for your data. It lacks any real durability or security features, so keep that in mind as you consider your options, but it certainly delivers excellent speed and performance.
