Out of a multitude of different SSDs I have in use, the best one at the
moment for consistent good performance and price point that I can
recommend is:

128GB Toshiba HD5D, 2.5" SSD, SATA III Slim 7mm 6Gb/s, 19nm MLC-Flash,
Read 552MB/s, Write 502MB/s, 80,000 IOPS Max

256GB Toshiba HD5D, 2.5" SSD, SATA III Slim 7mm 6Gb/s, 19nm MLC-Flash,
Read 552MB/s, Write 512MB/s, 90,000 IOPS Max

For my systems at least, those give consistently lower latency than
certain others...

There's a Toshiba mSATA but I've never tried one of those formats:

256GB Toshiba THNSNH256GMCT4PAGA mSATA 19mn MLC 2.5" Int SSD 471mbps
read 450mbps write

(Guess the rather old 8GB in my netbook doesn't count! :-P )

mSATA can sometimes be slower due to the less physical space meaning
fewer flash chips can be placed to run in parallel.

Check the reviews and tests...

You'll have to at least persuade Windows to accept other than "Drive C"
for its home partition... Boot loader adjust?... Chain it from GRUB?

The big question is whether Windows will accept a USB interface rather
than IDE/SATA for booting...?

Good luck,
