Pros: Super quiet, cheap, huge storage!

Cons: Breather hole in the wrong place for Macs!!!

Overall Review: I just installed this in my Macbook Pro (1,1) Core Duo. This is the model before the unibody. It's even more quiet than the factory installed Seagate it replaced. I didn't know Samsung made notebook drives but I guess so. They make everything else. DO YOUR HOMEWORK before buying this or any notebook drive. (I made the mistake of buying and IDE enclosure to my existing drive!) If you have the older (non-unibody) macbook pro then you're probably better off with the Seagates or WDs. I steered away from them because I read reviews indicating the WD drives are loud while the Seagate's are unreliable. I was going to buy the 500 GB 72000 RPM Hitachi but was afraid because many people complained about the breather hole issue. (The drive ribbon supposedly covers the breather hole which supposedly will cause the drive to fail fast.) Well this drive has the EXACT same issue. I got clever and used electric tape to hold the ribbon out of the way of the hole. It's not too difficult but be careful!!

Pros: Solid construction. Seems easy to assemble.

Cons: I can't use it so I really don't have any cons.

Overall Review: I mistakenly bought this after reading reviews of many enclosures. I didn't realize it was an IDE where I needed a SATA -> USB. I like the look of it and the feel of it but I can't use it. I'm going to RMA it.
