One of the best gaming SSDs now available at its best-ever price. Updated on 19 April 2021 If you're on the lookout for a cheap way to boost your PC or laptop's performance with a quality SSD, Amazon UK has reduced the price of its WD SN550 500GB NVMe SSDs to just £46.99, knocking a massive 38 per cent of its usual asking price, with free delivery for Prime members. The SN550 is a decent mid-range NVMe SSD and this is the cheapest we've ever seen it, even trumping its previous best-ever price of £50 on Amazon Prime Day. There's a reason people were rushing to get it at that price. The WD SN550 has incredibly fast speeds for both sequential and random reading/writing, and a data transfer rate of 8GB per second, which is a lot faster than other NVMe SSDs available for the same price (or more).
