I've got a family member's old laptop here I'm fixing and the HDD is busted so I was thinking about sticking a cheap SSD
in the thing for them. The user doesn't require much storage space and this cheap SSD has a better warranty than a new HDD for the same price. Then I realized that it's running XP, so no TRIM support, I'd have to use a TRIM tool - but it turns out the manufacturer (SanDisk) doesn't make a TRIM tool, though even if they did the Dell Latitude D620's BIOS doesn't give me the option to enable AHCI(even though the ICH-7M supports it).
The question is what's the worst that could happen if I go ahead and use an SSD anyway, I'm presuming it's just a speed issue? Would the drive just become slower and slower over time? Would it even be a noticeable decrease on first generation SATA controller speeds?
