Seagate Exos X18 12TB Internal Hard Drive Enterprise HDD - CMR 3.5 Inch Hyperscale SATA 6Gb/s, 7200RPM, 512e/4Kn, 256MB Cache (ST12000NM000J)

Update: I forgot to add that I purchased this as Amazon as the Seller, not a 3rd party, and when I checked the warranty on the Seagate site it was for 5 years.I have two Hitachi 2TB hard drives that have been working without problem for about 7 years (7200RPM). One drive has Win 7, Vista and XP on it, and the other drive is for Data (my main Win 10 boot drive is on SSD). But since I sometimes have to use Win 7, and these drives are a bit old, I was looking to replace them with new faster hard drives.I decided to try the Seagate Barracuda 2TB first since it was a low price. I was impressed that it is a single platter with two heads inside and is quiet. Also, when I first did some benchmarking with Crystal it showed over 200MB/s Read and Write. But if I ran it again, the numbers were not consistent and would be as low as 35MB/s. Using HD Tune showed that this drive has major drops in speed across the platter. I cloned my Win 7 over to it, ana it took about 4 minutes to fully boot, no faster than the old Hitachi. The 2 year warranty is also a concern. So I can't really recommend this drive as a OS drive, but would be OK as a backup drive or just a data drive if you don't need fast performance.I have also since then tried this WD Gold 2TB (good performance, but loud disk spinning sound and loud read/write clicks), the Seagate Exos 7E2 and newer Exos 7E8). The WD Gold was the Loudest drive out of the bunch, as I could hear the disk spinning (motor) and loud clicks when read/write. The Exos 7E2 wasn't as loud as the WD Gold. The best drive was this Exos 7E8 at $150. It was actually the quietest drive out of all, and also the fastest with speeds up to 240-250MBs, also has 5 year warranty that I verified on the Seagate site. When I cloned my Win 7 over to it, the boot time was 1min 45 sec, and remember the Barracuda was 4 minutes. So that right there shows the Exos 7E8 is faster for an OS drive.So out of the 2TB Drives that I tired, Seagate Barracuda, WD Gold, Seagate Exos 7E2 and Exos 7E8, the beat for an OS drive was the Exos 7E8 due to the fastest speed and it also being quieter than the rest.

Good deal and fast speed!!

Item listed under listed under New Category should be New.

Used in a Synology DS923+ NAS. Not on the Synology Supported list, but works perfectly. This model uses inert gas to extend the mean time between failures, which for a long term storage platform, is supremely important.I have 10G ethernet between my PC, a Microtik 10G switch, and the synology NAS. I get 1GB per send transfer speeds on large files. Multiple small files, it normally goes between 500MB and 1G.

Bought the drive thinking that the features and warranty would be great but the use of the drive for a personal computer I would not recommend! This drive should only be used on servers which reside in a different room than people. Very noisy!!!!The drive I removed was a Seagate which came installed on my Dell at time of purchase. I never heard a peep out of it but after 5 years it started to develop problems. I bought this drive thinking brand name and quality type of the drive was a good idea. NOT

Got the order quicker than expected and arrived without an issue.I've been a big user of this brand of hard drive, so I'm not expecting any issues with it.Literally zero complaints overall.
