outstanding service. After half a year my drive was disconnecting by itself frequently so I reached out to seller and they replaced it no questions asked.

Very good deal; 5 years warranty and very silent. Speeds are as expected (between 250MB/s and 150MB/s for sequential write). They have a weird feature that allows for power-disable the drive, but they ship with the adapter -- though if your NAS has the SATA power connectors embedded (eg. Jonsbo, Synology, etc.), hopefully it's compatible with it otherwise the drive won't spin. It's part of SATA 3.3 and later standards apparently. Despite my PSU being brand new I had to use the adapter.Edit: I ordered 3 of those and wrote the above after only testing one -- turns out the 2 others are dead: one doesn't even turn on (you can hear it starting spinning, stopping, trying to start again, etc. in an infinite loop), and the other one had growing unreadable sectors, before I even start using it (I gave up at more than 500). That makes me worried about the third one honestly.

I'm using this to help clear, consolidate, and warehouse data from several smaller external SSDs I have. Transfers have been fast and clean. I would recommend this to anyone needing a large amount of local drive storage space.

Seller was responsive and refunded me for a bad drive without qualms. Easy installation and not too noisy.

I recently purchased two 14TB NAS drives for my new Home Office set-up. I was on a (tightish) budget but wanted a good capacity which led me to the MDD units. I read the reviews from many of the Amazon "Experts" (naysayers) and flim-flammed between buying other units at a much greater price.I finally dived in and the drives arrived as new units (phew). After installation they ran like a dream - They are smooth (no undue noises or mechanical sounds), the upload / download speeds are as expected and, although it has only been a couple of months, they are performing as expected without any concerns.I am pleased I didn't believe some of the naysayers and went with my choices - You...well that's your choice !

Apres 2 semaines de formatage et rebuild toujours dans la même position. Donc ses disques sont en fin de vie. Maintenant comment retourner ? Le vendeur m'avise que je dépasse de une journée le retour ou remboursent possible donc 600$ dans les poubelles. Je crois que amazon perd de son service après-vente depuis 2023 car ça fait trois produits qui sont refusés pour le retour. Vive l'achat local.

Was sold by Amazon as new but is in fact renewed. The drive is noisy but that's to be expected given it's capacity and heavy duty construction. The five year warranty is very welcome and a SMART test shows the total runtime when supplied as only 319 hours.Overall I'd happily recommend this drive.

Item arrived a while back and I had not installed it until today. Had I looked closer I would have returned it. It is beat up, not a good sign for a brand new 14TB drive.Dropped it in my Plex box and formatted with XFS, it is loud..Runs cool, but audible across a room.Copied about 200GB of data to it. Read/write speeds are all over the place. Going to give it a day or so to see how it goes.Right now, I would not recommend.I've used Seagate, WD, Toshiba, Maxtor, HGST, and Samsung over the past 20 years.. None arrived looking well used, or made this kind of loud vibration noise (unless death was imminent).

I buy large, cheap hard drives like this for backing up my system. I have a 1Tb drive for boot up and operation with 3 5Tb drives spanned for 14Tb of data to back up. I bought a 16Tb drive refurbished, and it only lasted 2 years. I decided to buy one of these drives. The first of these hard drives came DOA. But the return and replacement could not be simpler or easier. Five stars for that. The working drive was very easy to install under Windows 10 home 64bit. The drive works perfectly with the standard W10 64bit drivers. Using Disk Manager, the time it took to set it up was trivial.The replacement drive came with a 5 year warrantee registration card in the box. The first one did not come with that card, but both drives came sealed in their anti-static bag. So I know both were new. Make sure yours comes with the registration card. Fill it out, and be sure to send it in. That 5 year warrantee is a big part of my decision to buy this drive.The read/write performance is typical of a SATA III drive. My backup software, (Macrium Reflect) achieved up to 1.2Gb/second backup speed, and reports 1.5Gb/second raw I/O speed while the cache provides a modest improvement at 1.7Gb/s. I assume the difference is compression time and overhead. Nothing fancy or special, just a solid performance. As of this review, the cost/GB is outstanding. It's an excellent value that will likely only get even better over time.

This product has gotten much hate, the drive I received was a rebranded Seagate Exos drive at a fraction of the cost. The 14TB MMD drive came with a 5-year warranty, the same as if I had purchased the Seagate Exos drive from an authorized seller. The drive has worked flawlessly and I have not experienced any weird behavior, fluctuating speeds, or a higher-than-normal sound. My array is located in another room adjacent to me (not soundproofed) and I cannot hear any drive noise. I would 100% purchase these again and plan to purchase more in the upcoming months as I expand my arrays and storage.EDIT: Its 2024 and I've know purchased 5 of these drives, all working flawlessly in my NAS, 2 report being Seagate Exo drives, the other 3 report themselves as MDD drives. I will continue to purchase this product for my NAS needs and hopefully ill never need to utilize their 5 year warranty.
