When SSD and USB 3.0 Come Together 158

    SSDs, whether they are internal or external will continue to be exorbitantly priced, so you're not getting larger storage densities for cheaper.

    This development is nothing new... I use a deconstructed external USD HDD container and just swap on SATA 2.5" drives as necessary; a SSD would just be another drive to toss on there. While SSDs are significantly faster than most thumb drives, the question at the end of the day is: "Do you have the disposable income for this storage strategy?"

    • The thing with putting a SSD in an ordinary external enclosure is that ordinary external enclosures are USB 2 at the moment and while probablly fast enough for a laptop drive (at least a laptop drive doing random access) they are going to seriously bottleneck a decent SSD.
