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: 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…

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: – 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…
