MDD (MD14TSATA25672NAS) 14TB 7200 RPM 256MB Cache SATA 6.0Gb/s 3.5" Internal NAS Hard Drive - 5 Years Warranty (Renewed)

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.

Works perfect for my NAS drive at home. Easy to install like any other hard drive. Storage capacity fits my needs perfectly.

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 put four of these in an Asustor 5403T. They are working fabulously, but they are super loud. It encouraged me to get my cabling straightened out so I could put the NAS in a utility room. Trying to watch television with these in the same room was unbearable.

I bought two of these 14TB NAS drives to replace my old NON-NAS 2TB drives (2). After setting them up on my old NetGear Ready NAS 201 I have had Zero issues, I use my Ready NAS 201 as my Plex server to share movies, family pic, and fun videos with family and friends with no issues steaming. Great Buy for the prices!! Remember, This has a 5 year Warranty in addition to Amazon the 30 day return policy. After 30 day, if you have issues with the drive. Contact the manufactory for a RMA to replace them! :)

Worked as expected. Decent pricing.

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.

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.
