I’ve got a laptop that I’ve had a few years (Acer V3-772G) which came fitted with a Seagate ST1000LM014 1TB SSHD 2.5" SATA as well as a Western Digital Blue 1TB 2.5" Internal Hard Drive1TB WD WD10JPVX Blue 2.5", 9.5mm, SATA III-6Gb/s, 8MB, 5400rpm. The drive speeds are killing me so want to ditch one of them and replace it with a SSD. Any ideas which one I should take out? The plan is to put the outgoing one in an external USB3 caddy and install the OS fresh on the new SSD. Thanks.
