What it says on the tin, and with the Seagate warranty. (Many other vendors are selling gray market Exos drives)

offers an excellent value and size is jSeagate 8TB Exos just right. Haven’t had a single Exos fail yet.

The Exos drives have always been good for me. They’re at a good price, faster speeds than the Iron Wolf or some other brand drives, not loud but not quiet (enterprise drives). I have several in my NAS and all of them have been performing well for several years now. Plus, drives from B&H have the manufacturers 5 year warranty with them.

These are our go-to drives for archiving all of our video and audio assets, raw and edited. We have never had a problem with them even over years of use. We archive assets to the drives and only go back to them if we need some file from the past on a new project of to update and old one.

Does the job with room to spare.

Just received these 2 days ago and still running them through the SoftRAID 3-pass verification process but my one hesitation in buying was the comments about noise. I have two of these in an open enclosure on my desk and they are silent. The fan for the enclosure is louder. This is with sequential writes and reads (not random seeking). For anyone curious, it’s about 24 hours per full write/read verify pass on these via SoftRAID. I have two going at one before moving them to the OWC RAID and growing it from the current 4x4TB to a new 4x8TB. Just realized the 4TB drives are 5.5 years old…

I purchased this drive to replace a failing drive in my Synology Network Attached Storage device. I have used Seagate enterprise drives in all my NASs for some time, and had good experiences. This drive tested very well, and has a 5 year warranty. While there may be some other good choices today, my experience with Seagate enterprise drives has been very good.

One died on our file server, but we’re getting warranty on it. unfortunately, we had to purchase another one to use in the meantime.
