Pros: 16TB, 7200rpm

Cons: It's kind of loud, warranty confusion

Overall Review: This drive is on the cutting edge with all the bells and whistles - EAMR, helium-filled, triple stage actuator, and a whopping nine platters. When it spins up, you can feel it and hear it running. I use it as a backup drive in an external enclosure, so I spin it down when it's not in use. I'm a bit unclear on the warranty policy. I got it cause I thought it was 5 years (as it is on WDC's site), but Newegg is listing it as a 2 year warranty, so if it's actually 2 years (which seems wrong), that would be a big negative.

Pros: - No errors with full badblocks pass - Lot's of space

Cons: - More expensive now than when I bought.

Overall Review: I previously owned WD Red Pro 18 TB drives. These are absolutely identical in terms of hardware (as far as I can tell). May have firmware differences, but I doubt it. So between this and the Red Pro, I'd buy whichever was cheaper. They both look identical and have same performance.

Pros: -It plugs and play

Cons: -None so far - It does make an odd noise when doing file transfers if its been idle for and extended period of time.

Overall Review: This is a solid HDD so far. I plugged it in and was recognized. Keep in mind you will about 10% of stated capacity when formatted (mine showed 16.3TB after formatting) though that is not unexpected. Drive does have a 5 Year Warranty. Was able to confirm through WD Online chat, they also advised that Data Center drives like this it is NOT necessary to register the product. WD chat was very helpful. I would buy again

Pros: Large capacity Fast especially given the size

Cons: Registration and RMA process is a pain due to a poor WD site. Once you get through, however, the replacement process is smooth.

Overall Review: I run eight of these in a Synology 1821+ NAS and have been pleased with their performance.

Pros: - Largest HDD on the market right now - Power efficient - Run quiet and cool - Reasonably priced

Cons: NONE

Overall Review: I have 6 of these, running along with some 18TB WD Gold which are essentially the same product. They are great for building NAS, DAS and surveillance use cases. Excellent enterprise grade drives. Highly recommended.

Pros: Huge storage and relatively fast for platter drive

Cons: Stopped working after a few months

Overall Review: Maybe I got a dud - but expensive if they dont last.

Pros: Lower cost compared to what available at the moment

Cons: None so far

Overall Review: I bought 3 of them here and there. It is totally fine. While not disclosed officially by Qnap, I took the initiative to install 3 of these and no hickups at the moment. Total compliance. Similar noise and heat level compared to wd reds @5000ish rpm and may be a slightly better performance.

Overall Review: Very fast, and high quality drive. Easy install.
