I'm in the market for a replacement HDD; 4TB vs 2TB. I settled for Seagate Enterprise. The 3 models are the same price & same warranty $150 5yrs,

The types are
512e (emulated),
512n (native) and
4Kn 4096 native

I have many a few good articles on the differences sine this aspect never came up before, 20 years playing around with computers. I only looked at manufacture, capacity, interface, speed, & warranty.

I'm running Win7 Pro (still), I may go to W10, but that is a maybe. The drives I have currently are one SSD and two Hitachi 2TB with a 512 BPS spec. I looked up the specs and all that is provided is "512", not 512e or 512n. So I don't know what they are. The drives models numbers are identical except for the last digit; 0 vs 1;
Hitachi HUA723020ALA640

From what I have read, 521e is the way to go for current compatibility.But, that seems debatable according to the articles. This replacement will be a 'storage' drive and it seemed that a 4096 BPS would be the better choice.

The Seagate Enterprise choices are;
ST4000NM0115
ST4000NM0085
ST4000NM0035

Input please.

This explains it:https://www.partitionwizard.com/part...ard-drive.html

For storage, you won't be able to tell the difference, but a 4K drive will be closer to the actual advertised bit capacity then a 512 drive.
As with everything, it is too early to tell, and 4K drives will certainly come down in price in the next few years

Would someone edit the title and the 1st 'type' drive I listed; change 521e to 512e since I can't edit the post. Thanks.

Seagate has an excellent article on the three types, thou the more I have read it seems to get more confusing;
https://www.seagate.com/tech-insight...ves-master-ti/

Foe those wondering, those drives I listed are $20 less then WD's Black 4TB with the same 5 yr warranty. As to WD vs SG, I known one local IT guy who stopped selling WD for the problems he had with their drives and their service. Besides, I don't feel like dealing with a one drive manufacture world if Seagate folds up. (I don't consider Toshiba a serious player.)

Back in the day, Seagate and Western Digital were both top players in the HDD market. I am not sure about Seagate's 4K drives, but their standard 512 drives have a higher failure rate then WD IMHO. Seagate may be lowering their price to be competitive but the drives may not last as long as the WD Black.
All HDD's fail, it is not a matter of if, but when. WD Black seems to last longer.

If you look at the 2nd & 3rd charts in Backblaze, based on percentages, WD fared worse overall over Seagate. especially the last chart. SG had one model in '16 that was bad, BUT that had a very small count that figure was based on.

Seagate has left me, and many clients, hurting an untold number of times. Never again.


For spinners, it must be a 7200 RPM Western Digital, HGST ... anything that comes with a 5 year warranty.

I too have had the worst failure rates with Seagate drives, followed by Toshiba and then Samsung. WD and HGST have given me and my clients the least grief. This is as far as spinners go. In my experience, when a client's HDD is malfunctioning and causing all sorts of problems, it's almost always a Seagate drive! I couldn't count how many times I've replaced Seagate drives with WD or HGST.

I won't use Seagate drives either I have been hurt also way too many times to ever try one again. WD or hitachi are the only ones I will use and as much trouble as I have had with Seagate over the years, they pale Toshiba issues.

Seagate, strict No No... I'd rather go with some cheap fake chinese SSD instead of a Seagate... The fakes are more reliable.. Been burnt too many times with Seagate..
