Over the past year I've noticed that my 4 and a half year old Intel SSD has slowed down dramatically. Accessing files/accessing the recycling bin/deleting files etc. And occasionally my computer would crash and I'd be presented with: "Reboot and Select proper Boot device or Insert Boot Media in select Boot device and press a key" I'd have to power off/on to bypass this message - if I restart, it would present me with the same message. So I assumed my OS was either corrupted or the SSD was nearing the end of its life. So I ran CrystalDiskInfo which reported no problems. Ran GSmartControl and it reported 10 re-allocated sectors. Ran Intel SSD Toolbox, and there were no reported issues. Bought a new SSD and fresh installed Windows and I haven't noticed any issues in over 2 weeks. So, I'm not sure what to make of this situation. If Intel's software says the drive is good, I'd think It's more accurate than CrystalDisk/GSmartControl. But I can't really explain the poor performance of the drive other than the old Windows install being corrupt. Would you RMA this SSD?
