Do you still have a laptop or desktop in your life running off a hard drive? Right now you can pick up a comfortably-sized 480GB SATA SSD for less than £30, thanks to a discount code available at Ebuyer’s Ebay store.
Use code BANK15 to drop the price of a cheap and cheerful Adata SU630 SSD from £35 to £29.78, and marvel at the speed and responsiveness improvement you’ll see on machines that were previously running on mechanical hard drives. I performed an upgrade using a similar drive on my brother’s old laptop, and it breathed new life into a machine almost ten years old.
