Seagate Exos X20 20TB Internal Hard Drive - 3.5 Inch Hyperscale SATA 6Gb/s HDD, 7200 RPM, 2.5M MTBF, 512e and 4Kn FastFormat, Low Latency with Enhanced Caching (ST20000NM007D)

Running for over a year with some pretty heavy use for a media server. No problems at all, installation was a breeze. It can get a little bit noisy when doing big transfers, but as long as it keeps working, I don't mind the noise.

I purchased one of these some time ago, and just now purchased another to install in a MSI 12TD-620US desktop. It works great.I see a lot of people have complained about the noise with this drive. The MSI desktop is whisper quiet. I don't think I have had a system this quiet before, so I was concerned about putting in a drive that was reported to be noisy. The previous drive I purchased is not noisy, and I am delighted to report that this one is also not noisy.One heads up - The Exos drive had great power management because it is essentially intended for servers. By default it parks the heads after 2 minutes idle, slows the rpm after 10 min idle, and spins down after 15 minutes idle. Saving power in a server farm is important.Windows 11 loves to ping the hard drives every 2 or 3 minutes, even if there is no pagefile on the disk. With Windows constantly waking up the drive this defeats the power management and gets annoying with constant windows notifications that it has woken up a device. I recommend tweaking the EXOS power management using the SeaChest_PowerControl to change or disable the advanced EXOS power management. This is a bit complex for novices, but search for "Exos power management Windows 11 SeaChest_PowerControl" and you will find articles explaining what needs to be done. I have not had to do this with my other Exos drive on Windows 10.

So far I have no complaints about this drive. Runs fast, massive storage, decent price and noise issues really aren't anything out of the ordinary.

seagate is highly reliable and the brand makes good quality products. drives still have defects and the one i had bought arrived faulty. it was packed in a small box dual layers of boxes and bubble wrap, it was well packed. since i did not need the drive just yet it sat on my desk unused untested for a few weeks, the return window is 30 days. i loaded into the hotswap nas cage and the drive immediately started to make a loud humming sound. i have used these drives for years and its not the typical sound it makes under normal operation. the drive reads/writes fine, smart data says the drive is 100% healthy but it has tons of sound and vibration just even powered on and not connected to the file system. when you have this much sound and vibration its always a prefail condition.the sellers return terms are just horrific. you are required to have the original box or you will be charged a 50% restocking fee. 50% of 378 for a 20 tb drive is 189 dollars to return a product if you don't have original packaging. if you look at the page again as of 12/5/24 the return terms are edited and omit having original packaging. if you contact amazon support its pretty hard since they dont understand the problem. so let me be extremely clear, the sellers terms are made so you only have 30 days to return a product and return requirements often will exclude/limit your ability to return a product leaving you with a very expensive paperweight.avoid buying from this seller, read the sellers terms on how and when items can be returned and if you are required to have the original box. if the return window is small and original packaging or % stocking fees are required avoid the seller and go elsewhere.

I bought two of these drives to backup data from a server, and I can say that they are fast, and not terribly noisy. They have great capacity for the money and I definitely recommend them. Although this has NOTHING to do with the manufacturer of this drive, I really wish that manufacturers would advertise the proper capacity of hard drives. The formatted capacity is based on 1000 instead of 1024 as is used in computers, so you will get 16.3TB out of this 18TB drive. Keep this in mind when planning capacity.Since your computers works on the binary system, there is an increment of 2 to the 10th power or 1,024 in each storage level. Therefore, in the computer system:Kilobyte (KB) = 1,024 BytesMegaByte (MB) = 1,024 Kilobytes or 1,048,576 BytesGigabyte (GB) = 1,024 Megabytes or 1,073,741,824 BytesTerabyte (TB) = 1,024 Gigabytes or 1,099,511,627,776 BytesThe only real issue I had with these drives is Amazon. Amazon shipped FOUR of these drives in plastic envelopes with NO padding of any kind... just bare drives. This is unacceptable. Be careful and do not accept drives that are not shipped properly, as there can be severe damage by mishandling.

This drive is louder than I expected.

I bought a total of 4 to date, and plan to buy another 2. I have a long history with Seagate drives and don't really trust any other brand. I have never had a Seagate drive fail on me, and THE ones that did over the decades were *all* from a particular other brand. That can't be a coincidence... Seagate drives are just more reliable.
