That's the price you pay for large-scale storage right now, but prices are tumbling, with this Toshiba coming in at 72p per GB.

What People Are Saying Give it to me straight

Performance

That performance sits the Toshiba drive in between the two other 19nm NAND users we've tested.
by Tech Radar (Feb, 2013)
However, the 4K read performance isn't that strong, and the writes are disappointingly low, which is something we've seen before with larger capacity SSDs.
by Tech Radar (Feb, 2013)

Temperature

Releasing the PCB revealed individual thermal pads protecting the NAND and controller.
