Pros: Long power cord in case you need it.

Cons: It doesn't work. At all. Period. I drive by a lot of speed limit signs that K you and report your speed. They all report my speed correctly. Spend the extra hundred bucks to get a better detector.

Overall Review: Why two places to connect power? The long power cord isn't a good thing (as listed above) if you do not need it to be that long.

Pros: SLC rather than MLC. Still a 7.7 user experience in Windows.

Cons: Does NOT support TRIM (which means it will degrade over time). Not that you can find that info easily on Intel.com. Also, only SATA II (3gb) not the new SATAIII (6 Gb). No cable or instructions or anything in the box. NOT RETURNABLE.

Overall Review: If you need to flash the firmware do so first, because it erases the drive (from what I read; but mine came with firmware actually newer than what was available on the Intel support website). Since I have an AMD board, the Intel tools do not work. And Intel's site's "determine what drivers I need" crashes my PC. Have to use AHCI in BIOS for the drive, so could not also use RAID on my board too. RAID also an issue for the card.
