I posted this MX300 525GB SSD deal a few weeks ago for 105 quid, now it's 20 quid cheaper at 98.60 euro (inc P&P to UK) working out at 84 quid
sterling if you get the real exchange rate (Revolut card!)
Didn't really need another SSD, but feck it, 525GB for 93 euro..!
One of the amazon.es Black Friday deals is this Crucial MX300 525GB SSD for 93.90 euro, which works out at around 80 quid + shipping.
For the money it's a decent enough SSD.
Cnet say "affordable, efficient and fast".https://www.cnet.com/products/crucial-mx300/review/
