I purchased this drive elsewhere (needed a guaranteed next day delivery) so my review is based purely on the drive alone and not on Amazon's packaging of such delicate equipment, as questioned on reviews from other hard drives here.
Samsung may not be market leaders in hard drives right now, unlike Western Digital and Seagate, but they unquestionably know how to make good hard drives. This is my fourth Samsung hard drive, with my previous three still in use and working after years of service. The whole intention of these 'Green' drives is to consume less power, produce less heat, and be quiet. Samsung's hard drives are well known to run cool & quiet, but this drive takes it to a new level!
After 24 hours of being connected, with over 200GB of data transferred and several hours of constant becnhmarking and testing, the drive is a very cool 23 degrees. During a file transfer, the disk is virtually silent. The side of my PC case is off, with the hard drive sitting outside of the case itself... I cannot hear it over my fans even when set to their lowest settings. If there is any noise from the drive at all, then it will all but become extinct when actually inside a case.
To the uneducated computer owner, some hard drives are better suited to some tasks than others. For instance, this drive has 2 excellent uses. Home Theater PC's (HTPC) or storage/backup drive. Due to it's supremely quiet noise and very low temperature, it is perfectly matched for a HTPC which is likely to be in your living room or bedroom - two rooms where lower noise is more important than better performance. Personally though I am using it as a backup & storage drive. The drive is surprisingly fast... some 'results':
Single 6GB File: 35 second transfer from main drive to Samsung EcoDrive 1.5TB
30GB Folder of 3GB Files: 6 minutes flat
So far I am hugely impressed. It's quiet, it stays cool, and it's fast. Devilishly fast, considering what it is. If you are currently looking into buying a large hard drive, then hopefully this will help you make up your mind on what to get. I was between this Samsung and the "
Western Digital WD15EADS Caviar Green 1.5TB SATAII 32MB Cache 3.5 Inch Green Power Oem Internal Hard Drive", but I couldnt be happier with my decision to get the Samsung!
