Works well enough
By Kyle Cronin
I bought four of these drives and put them into a Promise Pegasus2 R4 with RAID 5. With this setup I benchmark about 470 MB/s write and 360 MB/s read with Blackmagic Disk Speed Test. These speeds are well in excess of the speeds you will be able to achieve with a NAS, the marketed purpose for the drives. Only time will tell whether these drives will be reliable, but with none DOA they're off to a good start.

By Gadget Freak
Just what I was looking for, reliability. Obviously a 3-year warranty is a good indicator. The Deskstar NAS is a new product. It has the 1M MTBF vs. the regular Deskstar 7k4000 (HDS724040ALE640) which has a 0.8M MTBF. The NAS version also has a rotational stability sensor to help monitor the smart status better. I was looking for additional external storage for backups & videos. I installed 4 of these in an 4-bay external USB 3.0 enclosure (Dyconn Quartz 4). For around $1100 total installed cost, you can get nice 16Tb setup for all your "stuff". I've got mine connected to a MacMini. A good (non-SSD) 3.5" drive has about the same read/write speed as USB 3.0, thus in an external USB 3.0 setup, it will give you ~170-180 MB/s regardless of RAID setup.
Update #1
I was able to test drive speed vs various other drives. This drive performs as expected. I did not test in a RAID configuration. (sorry about the formatting, the last two nos. in each row are Read/Write in MB/s), all tests with BlackMagic

Update #2; I just tested four of these drives in RAID5 mode on the 4-bay USB 3.0 Dyconn.... way better than expected 250 Mb/s Read, 241 Write. Woo Hoo! So, double the single drive mode.

By Jeff Welch
Other than using an SSD, this is by far the fastest drive I have ever had, that said I purchased it for its size and reliability. Size is great, speed is awesome. The jury is out on reliability for me, maybe I'll revise this in two years!.
I like to retire my drives after a couple of years to head off reliability problems before they happen. I am in the process of using this drive to replace two 2TB drives from another manufacturer. I lost a drive on a laptop a few years ago and ever since I have become very paranoid about loosing my data (basically everything that I have made for close to 20 years, plus many movies, songs and pictures, I delete NOTHING).
If you have read a lot of Hard Drive reviews, you are probably more worried about which drive to pick now then when you started. After several weeks of research and reading, HGST seemed to me to be the best choice. Time will tell.
Assuming this drive works well over the next few months, I will purchase a second one and mirror them for data backup.
