Great storage at a great sale price (when it was on sale)

Great product at a great price, only wished I ordered a second. Can use as external or if I need to can shuck it to pull the drive. Ordering process was quick and easy, shipped even before they said it would. Will do so next time it goes on sale!

Perfectly acceptable

I plugged it in, and it worked. No issues no problems. I purchased it to backup 10TB of data from my Synology NAS, which I have done, and I cannot think of a single criticism. It does what I purchased it to do.

Pretty fast external drive.

Pretty fast external drive. A little noisy though. Had to place it on a towel due to it vibrating the desk. Otherwise a great value!

Great drive for educators!

A must for educators who need lots of room to store their videos. The massive size ensures plenty of raw footage and rendered products will have a safe place without having to delete their roll to make room for a new batch. It's reliable and works nicely with a Mac or PC. Be prepared to live with the idea of it falling over since the only rubber feet it has are on the side so vertical storage is your only option.

Great Performance for the Price - Great Value

This drive represents a great value as far as GB per Dollar. It performs well, especially considering that it's an external drive. I use it to store video projects, but many times I'm actually editing from this drive without noticing any disturbing performance issues, even though we all know this isn't a high performance editing drive. The only con that I can mention, is that it is noisy. The head movements are very loud if you have the drive on anything that can resonate or amplify the sound. I have it sitting on a block of foam and it quiets it down quite a bit.

Loud but Solid

Love the look, size, ease, and functionality of this drive. But I wish I knew how loud it can be before I set it up in my bedroom. Of course it only seems to make noise when I'm trying to sleep. Otherwise it's great.

Who knows...

Hard to do a short term review on a hard drive. It's basically like any other external hard drive. It will be use more as long term storage for stuff like like photos, music, videos. I hope it last a long time...

High-grade 7200rpm Bulk Storage

I was in serious need of extra space, and two of these drives fixed me right up. It's luck of the draw as to what grade of drive you actually get, but both drives I received were Exos enterprise drives, 7200rpm, and I couldn't be happier. Highly recommend.

Awesome Enterprise level HDD

My particular unit had an Exos drive which is Seagate's high end enterprise drive. Many people do shuck these to put inside NAS enclosures and say it is easy to do so. I personally have it hooked up to a RaspPi and use it as a basic SMB share. It has great performance and a ton of space. My only concern is that the enclosure is not good for airflow and I worry about it overheating under excessive utilization.

great performance, but loud

Great performance though somewhat loud when there's disk activity. I would not use this where a low-noise environment is needed. Benchmarks report that there's an Exos drive (ST14000NM001G) inside.

Seagate External Hard Drivw

This external drive always works well for me, and I like that you can place it horizontally on a desktop. I have about ten of these.
