SSD TRIM Command on RAID 0 Possible - With A Few Riders
Intel made it possible for SSDs to utilize the TRIM command feature when striped in RAID 0, provided a few meaty requirements are met. The TRIM command feature works to minimize write performance degradation on SSDs, but thus far it has been impossible to enable the feature on any other host controller mode than standalone AHCI, due to the manner in which the feature works at a physical level.
According to a report, TRIM over RAID 0 will be made possible with Windows 8 operating system, provided the system is running an Intel 7-series chipset (such as Z77 Express), has RAID BIOS (Option ROM) version 11.5 or higher, and Rapid Storage Technology (RST) device driver version 11.5 or higher. While obtaining the required Windows and driver versions is relatively easy, the RAID Option ROM version is in the hands of motherboard manufacturers, who have to release motherboard BIOS updates that include the required RAID Option ROM updates.

The degradation of HDDs really only make them last 5 to 8 years if you are lucky. SSDs in perfect shape will always outlast HDDs in perfect shape.
Stuttering
BSODs
Random Chkdisks
Drive gets detected but doesn't load something
You try to read you get a glitch
The sudden deaths imply that the controller got overheated this is a problem with the manufacturer not the NAND or Controller. <-- this usually always happens within RMA time.
Another case of sudden death is a bad power supply or bad cables connecting to the power supply. <--- Again, always within RMA time.
Despite all that it is the future.
SSD's are perfectly safe if you take the right precautions. Precautions you should take with ANY DRIVE. Mechanical or not.
The replacement drive has been working without issues since, but I am prepared for it to fail at any time. We are too poor for RAID 1 (50$ per month for a 2nd drive), got a real-time backup working though
Sell some of us schmucks some of your goodies.
