Ran 4 of these in a storage array for a few years. They replaced a similar array built on smaller SATA drives. Needless to say, they're muuuuch faster than the SATA drives.

A good amount of storage for a reasonable price.

I bought it specifically for usage in a NAS, which is the intended usage of the IronWolf. It's cheaper than its counterparts from WD. It's a fast HDD.

Works as described. Excellent reviews for need to have long term storage solutions. Videos and RAW photos pile up quick. This solves my immediate issues.

Fast, Fast. Yes, twice as fast as SATA II.


I have few 4TB hard drive and all of mine are worked properly out of the box with very large 2500+ steam game library nothing unusual to report here and even plan up grade my Emby media server with seagate 3tb drive to the same 4tb really soon. As for the rotational speed is just fine 5900rpm I'm not sure why other are make a deal out of it as it is still pulling a 125+Mbps transfer rate sure it no speed demon like SSD unless you wish to spent 1.6k on 4tb SSD drive a reg mechanical drive dose get the job done.

These drives were on the compatibility list for my Synology DS218+ and they came recommended by a trusted IT professional, so I bought two of these drives to add space to my NAS (I was replacing a single 4TB drive). I added the first drive and it added seamlessly to the RAID array. It took a few hours for the NAS to populate the new drive. I was then able to hot swap the second drive. Extremely easy installation (which says as much for the DS218+). It may just be my perception, but these drives feel a little faster than my previous drive.

Mine came in retail boxes. Working for one week so far, so only time will tell how long they last. I am using them (8TB 5640rpm) in a Synology DS1010+ that is 10+ years old and they seem to be fine.
