Seagate 8TB IronWolf Pro 7200 rpm SATA III 3.5" Internal NAS HDD

We used these as internal backup drives in a Hyper-V server, after using Seagate Archive drives for several years. We are seeing backups taking less than 10% of the time of the Archive series.

Performs well, but runs hot--about 120-130F, even in a direct fan-cooled drive enclosure pushing a lot of air over it. I prefer their 5900 RPM NAS drives as they run around 95-103F under same conditions, but Seagate doesn't make it at that speed beyond 4TB.

Finally a drive that lasts a reasonable amount of time. I have replaced many of my hard drives the past few years and this drive is the most reliable I have used yet. It costs a little bit more but is completely worth the extra money.

Insane number of bytes on a single device. In 'my day' this amount of storage would have filled about 300 aircraft hangers and I suspect wouldn't have been quite as reliable.

No problems, just works.

Huge capacity & awesome speed. Power at my fingertips!

UPDATED: 9/27/17: I had (as below) a crash 31 days into operation. It has been one month, but I got my drive back with 99% recovery off the damaged HD. This may not seem "perfect" but in a NAS array it would allow a total rebuild to perform MUCH more quickly.

Two 8TB and two 10TB Ironwolf Pro drives running cool and well in 4-bay Synology NAS. No issues.

So far, so good. Fast drive. Great capacity.

As a long time builder of my own PCs and having a fairly large "data" collection, the majority of my HDDs have been Seagate brand. I have never had a drive fail, or experience any issues with them whatsoever.
