Not far off what i paid for my Corsair MP600 2tb when i bought it new a few weeks ago, also normal ssd are below £200 now so they need to rethink there pricing, https://www.ebay.co.uk/itm/Innodisk-2TB-2-5-3TG6-P-Series-Rugged-Standard-Grade-SSD-0C-to-70C-3-Year/333482895119?epid=0&hash=item4da521270f:g:LGwAAOSwf1leFmIw I know which one i would choose.

The price isn't so high, this one is self encryptating compatible, the normal 2 to is one of the "premium brand" with the lowest price with Sandisk.
