My boot drive a Seagate 1tb failed. I replaced it with a smaller Seagate but seems slow so considering replacing it with a SSD for the boot drive. SSD are published as SATA 3 but THE HP site describes my SATA as just a SATA no numbers "Original driver for the Intel SATA AHCI and RAID Controller solutions." They tell me a SSD needs a SATA 3 but I suspect mine is a SATA 2 which is slower. Anyone know for sure? The biggest my OS has been is about 75gb so will fit well on a SSD. Can I assume a SSD will look like a HD in plugging it in, etc? Anyone replace a Pavilion drive with a SSD? Advise? tips and traps? Anyone to recommend a SSD for medium to low usage? Say, about $100?
