I have a 2012 Mac mini (server version) with two 256GB SSDs installed. If you're uncomfortable with the lesser-known brands that populate this category, you can get a Samsung drive for about $40 more. There are many similar drives available from other lesser-known vendors. I picked mine up from Amazon for about $90. The drive I bought is the 256GB OTG (which stands for On The Go) from MyDigitalSSD. In this review, we take one such tiny drive for a spin, er, access.
External drives are starting to crop up using the mSATA interface, a smaller, card-sized interface that's similar in form factor to the Mini PCI Express interface. That's been changing and we're now all able to benefit. Because they were intended to fit in place of laptop-size spinning platter drives, solid state drives were initially built to have the same format and cable connections as hard drives. As SSDs have taken over the storage world, there has been a quiet little change in external storage as well.
