Pros: Works as expected. Comes configured as SATA so if you want eSATA you have to set the jumpers prior to installing.

Cons: At least in my machine I have to remove the card to change the pins to set as eSATA or SATA.

Pros: It's fast

Cons: Clone software would not work, even attempted to put My HP Envy Touchsmart UEFI into compatibility mode and still wouldn't see the internal HDD. I've tried to find an update on the Kingston website, but found nothing.

Pros: Cost

Cons: Not compatible with ANY Swann HD DVR Security System. I did my best to avoid this issue, even went to Swann Site before purchasing. There is no list that I can find of compatibility. When I received Camera I attempted to connect to my system, had to call Swann Tech Support and they informed me there is only one compatible PTZ camera for my system.

Overall Review: I only hope AntOnline, the seller will accept the RMA.

Pros: I must admit after reading the other reviews that I was worried I'd never see the product; but I did arrive and was exactly as advertised and worked as expected. I even ordered one from another site just to be sure I'd get one. Took about a week to arrive, I was even able to track it all the way from Origin to destination through USPS, which is unusual from my previous experience.

Cons: None yet.

Pros: Good performance; had up to 300mb xfer rate using eSATA. Detected every time in several OSs. Easy assembly. No overheating issues even with WD Black H.D. installed and running for hours.

Cons: On rare occasion when using eSATA the computer will lose the drive and have to restart to get it back. This seems to be specific to a computer, meaning it has never happened on some computers. Not being eSATA powered is my biggest complaint. Not all computers have a USB on same side as eSATA and have had to use USB extension a few times.

Pros: It works as expected.

Cons: None
