This 4TB NAS internal HDD is a box, that I use with another box I own called a NAS.The 4TB NAS internal HDD does what it says on the label. It is goes inside a NAS and does HDD things.I'm not a technical person, but I know that if I buy things that use acronyms, it's usually more technical, and this product has two acronyms, so it must be good.This HDD will be ace, until the MTBF target is met, and then because of the way these things work, I'll have to buy another one. Or two. Because that's also the way it works.Great service, the person at PBTech who handed me the HDDs processed my eftpos transaction very smoothly. Would buy again.

I own several WD RED 4TB NAS drives and also couple of Seagate NAS drives. However, when receiving this 4TB IronWolf drive, it was a bit surprise to me as it is much thinner (only about two third of thickness) and lighter than the NAS drives which I bought several years ago. Besides, the antistatic bag is not as thick as before. This really make me a bit worry about the manufacture quality after the reduction on materials.Anyway, the drive is good so far and it fits my new bought QNAP TS-133 NAS Enclosure well. By the way, I have to say the thin disk does make air flow better inside the Qnap TS-133.Another advantage of this disk is that it runs quietly. I have been doing the bad sector scan for the disk and it is quiet.

Seagate as a brand I've always found reliable and fairly priced for what you get. This is the first of their NAS HDs I've used, but based on the reviews and the experience I've had with their general computer drives, I expect to have a good long life out of it. This was purchased to slot in a brand new 'basic' NAS, and it was picked up by the server with no issues. We'll have to see what it's like in the long term, so if there's any issues' I'll make another review.

Christopher's review of Ironwolf 4tb Nas 3.5in 6gb/s Sata 64mb

Pros: Bought to replace a failing HDD in MY Synology NAS. Wasn't on the Synology list of approved drives, but loaded without any problems at all.Cons: No

Excellent product and service

Excellent product and value. These NAS HDD were easy to install in my NAS drive replacing older drives. I should also highlight the great service from SCAN computers. Great prices, fast, fast delivery and excellent comms.

It’s a hard drive. Time will tell.

It’s a hard drive. Reasonable price. I have rated 3/5 as it is difficult to know if a hard drive is going to be a good’un until tens of thousands of hours in to its life.

Martin's review of Ironwolf 4tb Nas 3.5in 6gb/s Sata 64mb

Pros: Drives fitted to NAS easily and up and running with no faults. After 6 hours of automatic raid repair my Synology DS416 NAS capacity increased from 3 to 6 TB.

NAS drives

Needed more disc space. Popped a couple of these into a NAS. They work. If they're still working in two years time I'd give them five stars.
