Seagate 3.5" 14TB Enterprise Capacity (Exos) SATA 6Gb/s, 7.2K Rpm, 256M, 512E/4KN, Helium

The 0008 is a little chepaer than the other ST1200NM drive. Best I could tell it is because the 0008 drive does 512E but doesn't support Fast Format to allow direct 4k blocks. I could be wrong but anyway I had 4 of these and one failed so I needed to buy another one.

Giving it a 5 star. I wanted to build a personal NAS with RAID 6. Drives seemed to perform well, not getting hot and virtually silent. I'll provide some updates later after having them tested in more comprehensive way.

Cool, performs, good value; firmware and 4K setup tricky

These Exos 14TB X14 drives are working great in a new Synology DS1621+ after a week under load. I purchased directly from Newegg (seller), for the 5 year warranty and at a price better than other 12-14TB 5400 and 7200 NAS drives with shorter warranties. Purchased and tested 7 drives, installed 6 as RAID-6, keeping 1 for spare. With 10GbE, I measured 650-700 MB/s combined sustained reads and writes (tested with AFS, SMB3; Btrfs, w/o folder integrity protection). Drive temps reporting 30-32C idle in a 68F/20C office. The NAS is quiet enough at idle to sit here in the office but the seek chatter if six drives is too loud so this is going into the server closet where it belongs. These 4Kn drives ship formatted with 512 byte sectors, which appears to be the rule for the ... MoreThese Exos 14TB X14 drives are working great in a new Synology DS1621+ after a week under load.

The NAS is quiet enough at idle to sit here in the office but the seek chatter if six drives is too loud so this is going into the server closet where it belongs. These 4Kn drives ship formatted with 512 byte sectors, which appears to be the rule for the industry. I had to use a command line tool to set the drive to 4096 byte sectors--the fast "format" command to set 512 bytes only takes a minute! Downsides: It was tricky to update firmware from SN02 to SN04 and change sector size from 512 (emulated) to 4K (native). I tried to make USB bootable SeaTools drive but failed to format the memory card. Tried to run Windows 10 SeaChest and SeaTools with a drive mounted in a PC but it wouldn't write the firmware or make the 4K block size stick. I'm guessing this was an admin privilege issue, but also wanted to save the drive swapping on a single PC. Luckily I was able to run the binaries on the Synology NAS. I used ssh/scp to copy the Linux SeaChest_Lite binaries into /tmp on the new NAS, then ran "sudo ./SeaChestLite_101_1183_64", upgraded firmware and set the sector size. I saved Drive 1 for last since it writes over the DSM image. Seagate's firmware release notes didn't say what was different between the two versions. I tested the drives before and after and didn't notice any differences.

Does what it is supposed to do

I wanted to add a large amount of reliable storage to my home network on a budget. This seemed to be the best deal available for large capacity drives at the time. I paired two with a Synology DS220j. These booted and formatted with Synology Hybrid Raid (SHR) in a few minutes with approximately 12.6 TiB total capacity. All in all, a great solution with no drama. For those of you in the previous reviews who are bad at math, and are complaining about the storage capacity, google "14 TB in GiB" for a helpful conversion. All hard drive manufacturers have been calculating advertised capacity in powers of 1000 since time immemorial. These drives are showing the exact capacity that I would expect on my NAS in powers of 1024 (13039 GiB or 12.7 TiB)

HIgh capacity at a good price

Upgraded my Synology DS21+ with a pair of these - so far, so good. A bit noisier than the 4TB WDs they replaced. THese are reconditioned, manufactured in 2019 - hope they will last another 5 years of light use!

Honest as it gets

This hard drive is loud. Do not forget, that it is designed for Server environments. Where the noise does not matter. I use it as my STEAM drive in my Desktop. It does sound like it is broken, but again...faster drives are louder and if you do mind it then you are in for a very good deal. Under Windows you will have about 10TB Under Linux its little closer to 11TB 256MB cache is very helpful. If you plan on doing similar setup like i have, where there are more READS then WRITES, then go it that BUY botton

Nice 14 TB drive, but only formats 12.7 TB

* The drive worked well for TV media storage, once formatted. * I need win 7 for Media Center, but Seagate did not know how to format the drive. * I'm familiar with the decimal (1000) to binary (1024) conversion problem, but I expected this 14 TB drive to deliver at least 13TB but it only formats to 12.7 TB * Formating the drive on a Win 10 machine then installing it on the Win 7 machine solved the problem.

Seagate Exos drives may have issues...

YOU MAY WANT TO AVOID SEAGATE EXOS DRIVES. Four months in and one of four Exos X14 14Tb Sata drives in a R10 array has failed due too excessive SMART errors. Very disappointing given the inve$tment involved. The 12Tb EXOS12 version of this drive (ST12000NM0007) is now showing alarmingly high failure rates at backblaze which I view as a bell weather in these circumstances. Seagate has firmware update SN03 available for the 14Tb drives, but I can find no information on what this firmware update addresses which is disappointing. Running four drives in a qnap turbo rack mount in the basement. During my day job, I work with all aspects of enterprise storage solutions, si, this isn't my first rodeo.

So far, so Good

Works perfectly in SuperMicro 847 case. Formatted is 12.733. Before anyone starts complaining, all manufactures state their capacity in TB meaning 14 TB = 1,000,000,000,000 bytes. So a true TB is 2^40 power. 12.733*2^40 = 14 TB. Same is for WD, Hitachi, etc. So far, humming along just fine in Raid 10 Configuration. Used for Work System Backups off laptops so very fit for purpose.

The Seagate Exos X14 drive runs too hot to trust Help! do I need to return this hard drive?

It was a great price. It runs extremely hot and I don't trust its durability. It is slow compared to my 12 terabyte WD. I have the drive in a 5 bay enclosure non-raid. It runs 2 to 3 times hotter than the WD and my other 8 and 5 terabyte drives. I purchased an additional fan for cooling. I did not answer the question about reliability because I am not sure. If Seagate tells me it's okay to run hot with noise perhaps I would be okay. I had planned to make it my go-to drive for storing my pictures. But, I am not comfortable with the Seagate hard drive.
