I believe this is a SMR drive which some do not like.

I have the same drive and have been using it for over a year for backup. No problems encountered.

Of the 2, I would recommend the Costco WD drive instead. The reason is that that one is traditional PMR, whereas this Seagate one is SMR.

What does that mean in layman terms?

SMR - which stands for shingled magnetic recording has the same read performance, but has significantly worse write performance. So if you copy a 10GB file, the first ~2GB might be written at regular speeds, but after that it'll drop to about 20MB/s - often worse than USB 2.0 speeds.

Eventually the disk essentially defragments, and performance returns to normal until the next large file copy.

SMR is usually intended for write once (at painfully slow speeds IMO), read many - abbreviated as WORM.

Many buy external drives for use in a NAS and smr drives are not suited for use in a server.

I have this same drive and have never had it drop to usb 2.0 speeds when copying files to and from the drive that range from 15 to 80 GB.

mmm in fairness, it might not be quite as low as that, since I'm speaking from my experience relatively early on when Seagate first started using SMR drives in their portable HDDs. These ones now have a much higher cache (256 MB), iirc - which helps mask performance hits.

I have been using the seagate 6TBs (SMR) from shoppers for a while now. I get around 120MB/s, but I use it for backup, so have not had to move files around. That was a good deal for $100 + 20x pts, and with super redemption, essentially brings it down to $50

Copying to the drive averages around 80 to 90 MBps. I don't have a fastdesktop (i5-2500k) and the usb 3.0 controller is an Etron which isn't the best usb chip.

for a 8tb drive - 40mbs is painfully slow..
