Great product at a great price
Fantastic customer service

Fantastic Customer experience

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!

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

It does what it's supposed to do and I highly recommend it! By the way, it happened to be on sale and bingo no brainer purchase. Thanks guys!

BINGO!

Works good, bit slow but expected

Affordable Space

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.

Perfectly acceptable

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!

Pretty fast external drive.

Love it

This drive works just great. It is super fast, quiet and reliable. Would purchase again.

Fast and Quiet

Solid and reliable

Works great - Now have a complete backup of all business files

Great harddrive

this External Hard Drive is my new replacement to my old 2Tb drive, works perfectly for my Mac mini to house all of my photos. Also, the price was right too

Upgraded

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 drive for educators!

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.

Great Performance for the Price - Great Value

worked right out of the box!  have not encountered any issues with backing up or manipulating my files once I have migrated them to this drive.  only wish they had a larger size one to purchase (smiles)

worked right out of the box!

Came exactly as advertised. 8TB of storage, works perfectly.

8TB of backup storage

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.

Loud but Solid

Seagate 6TB 3.5" Expansion Desktop External Hard Drive, USB 3.0

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...

Who knows...

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.

High-grade 7200rpm Bulk Storage

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.

Awesome Enterprise level HDD

Good product, came with exos x16 enterprise drives.

Good drive inside

Best worth

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.

great performance, but loud

Appears to be a solid product. Crystal Disk info reports inside is Seagate Ironwolf drive. Good communication from Adorama on shipping of original OOS purchase.

Seagate 14TB purchase

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.

Seagate External Hard Drivw

You actually only get 12.7tb and it is very loud when it is writing to disk.

Solid 5/7

Great desktop expansion drive. USB 3.0 is ok but I shucked mine into a net app array and they work great.

Great drive

good drives, way better than western digital drives
