Summary: Too soon to tell how reliable it is. However it sure does reduce the boot time to say the least. You also have to remember that, with this capacity drive the OS is the only thing you can put on it. That includes the default My Documents, Downloads, Music,..etc.
Summary: Yes, it's functional, but it's so pitifully slow that my spinning magnetic drive is literally orders of magnitude faster. Unless you are desperate for the power savings it may provide (which I didn't test, because it was unusable for me due to the speed problems), you should not buy this.
Summary: I replaced the HDD with this SSD in my very old IBM ThinkPad 600E. I then installed Debian Linux 7.1 (from the a DVD) and everything booted right up and is very quick. Very happy with this upgrade. Very fast shipping!
Summary: I bought this disk for a Gateway M520 and even though installing both Ubuntu and Windows was successful and I could see the data in the disk, the disk never managed to boot the computer at all.
Summary: I have an older PC that's used for a weekly automation task. It had an older 20G IDE drive, which was beginning to show errors on some diagnostics. Since this task must run--and run unattended, I decided to switch to an SSD drive and eliminate all moving parts in the disk subsystem.
