I think this is a really good deal on the Seagate FireCuda 2 TB 3.5 inch Internal SSHD. Unfortunately it is the larger 3.5" version so not an option for consoles and laptops like the 2.5" version of the same drive but still a great way to upgrade a desktop giving much more capacity than a SSD but comparable performance with data it has cached.
A good middle ground between HDD and SSD.
Simply add the warehouse version to basket, at £82.60 and go to checkout and it should have the 20% off making it £66.08 (before any delivery charges).
