WD GREEN SATA

Cheap, but the performance penalty of SATA rather than PCI Express means we can't recommend it

PRICE 240GB, £20 (£24 inc VAT) from pcpro.link/339labs14

At just £24 for a 240GB drive and £38 for a 480GB drive, the WD Green is certainly cheap A for an SSD. Similarly cheap 1TB and 2TB drives can be picked up. There's a reason for this: it doesn't use PCI-E at all but the older SATA interface.

(Note: this drive isn't to be confused with the WD Green SN350. Although both models share the "Green" name, the SN350 is an NVMe drive, rather than a SATA one.)
