This hdd will format to about 18.4tb of total useable space. Filling may take some time but it can hold ALOT of information. keep in mind that the drive does get hot when writing to the disc. Just keep a dedicated fan on it when in use for long periods of time. During day to day use it performs as expected with an average transfer rate of 140-175mbps. Make sure to put it into a good hdd enclosure or ventilated PC tower.This is a great large drive %26 definitely worth buying.

I purchased four of these drives to upgrade an existing Synology NAS box. I was previously using 4 x 16Tb Seagate EXOS drives and decided to upgrade to the 20Tb versions. The new drives worked perfectly and the 918+ NAS unit rebuilt the entire array in about 2 days which, given the size, was very impressive. These drives, despite their greater capacity, seem to run cooler than the 16Tb units they replaced. In addition, the new drives spin-up faster from power-save and operate more quietly. An excellent upgrade. The drives supplied were official UK stock and their labels show Seagate UK's address, so these are not grey market units.

Brought this when it was on offer for just over £300 pushing it above all others for £/TB.I was dubious about spending that much on a single hard drive as there are a lot of refurbished and re-stickered drives in circulation however, once this came and i checked it over it was new.It came packaged in its anti static bag, surrounded by a foam sleeve, inside a carboard box so top notch packaging.Read / Write speeds are as advertised.Noise levels - This is installed in a Gen 10 Microserver under my desk and honestly i can hear it emitting a faint hum when idle but it doesn't bother me.

If it was like that all the time i would probably get annoyed.But remember, these drives are enterprise and meant to be tucked away in a server room. They are not marketed for us pro-consumers.

I'm on my 8th drive and *knock on wood* no issues or failures. I've purchased from X16, X18, and now X20 series. They've been flawless. I'm using mine in NAS setups and they see a consistent workload pretty much 24-7. These are designed for data centers so no concerns. They are noisy for hard drives. If noise is a concern the Iron Wolf series is quieter. But Seagate claims twice the mean time between failures for Exos so it's worth it in my opinion. The internet seems to hold the Exos line in high esteem so I felt the was the best option for me.Read write performance varies based on workload but in my setup doing file transfers I've seen single disk speeds of 265MB/s read and 170MB/s write. That's about the limit of my setup so I can't speak to what your results ... MoreI'm on my 8th drive and *knock on wood* no issues or failures. I've purchased from X16, X18, and now X20 series.

That's about the limit of my setup so I can't speak to what your results will be. The onboard cache seems to be plenty. I know other disks are moving to larger caches but I'm not sure if it's needed for a single actuator drive.I've got 150hrs+ on this drive so we're probably out of the risk zone of dead in a day or two problems with HDDs. I have thousands of hours on the X18s and X16s. And much of that is write cycles. I highly recommend Exos for any kind of storage use case. For instance this unit I placed in a 3.5in external enclosure for portable storage. And it still came in less than what some 20TB external drives sell for. Plug for the NOVUS usb enclosure. It's a great box for these or any other 3.5in HDD.
I purchased this as an open-box with a decent price from new. As a 20TB drive, in reality it only has about 18.5TB usable space per Windows 11. I was a little alarmed as it looked a bit strange with a stick-in sheet of sheet aluminum covering the back of the drive where the spindle mechanism was exposed. However, other than being a bit louder than the 16tb Western Digital paired with it, it's working great so far after a few weeks. Regarding how loud it is: if I had not known any better from other reviews mentioning how loud it sounds when accessed, I would have thought it was broken.
Woah these were super poorly packed with 2/4 drives I ordered DOA and Seagate refuses to extend the warranty to order date. Literally four drives in a small box with air packing around them with some already popped. Shame on newegg and Seagate for even letting this happen. Shame on me thinking that I would get a better experience than others.
I absolutely love these drives. however several were DOA because Walmart literally just threw all the drives in a box with little to no protection. They used a single air bubble to hold 7 drives in place and prevent shifting side to side. This popped in shipping. My guess is because they didn’t put anything on the top of the drives. So they could bounce around completely in the box. Idk why these drives weren’t kept in their original shipping containers. But I’m sure even the drives that survived, will have premature deaths
Looking to purchase 4 new ones. Unfortunately, when I saw this, I ordered two orders for NewEgg, both came in non-OEM packaging bubble wrap, in a sealed bag. Verified the Serial on the Seagate website and was short a year of the 5 years stated. not sure if they were new or used and I returned all 4 HDD. I am not saying NewEgg is the issue always had good experiences other than I no risking the unknown in my NASs
I decided to populate my newest 24-slot Synology NAS setup with a mix of these babies and their smaller kindred rather than pay exorbitant prices for the OEM drives... and I've been extremely happy with the result. A simple patch to the system supported drive database (search GitHub for Synology_HDD_db) stops DSM (currently 7.2.1.) from complaining about them and they've run flawlessly as fully supported drives for months. (Note: some DSM updates may require a repeat application of the regularly updated patch, so installing it as a scheduled repeating task may be desirable.)
We've used these in a SAN before with good results. Using now in a NAS. Building it out, we ordered 17 for a 16 drive box enclosure. Highly suggest having extras: three of the original 16 were DOA. B&H replaced rapidly, with no issues - now full NAS is running at speed. Seems normal, but odd to have so many fail immediately.
