HGST Ultrastar HUH728080ALE600 (0F25739) He8, Helium Platform, Enterprise 8TB 7200 RPM 128MB Cache SATA 6.0Gb/s 7 pin Serial ATA 3.5" 512e ISE Internal Bare Hard disk drive; Advanced format technology

I was in a desperate situation with a server I manage and needed assistance ASAP, or we risked losing critical data. The company saved the day, shipping the disk immediately and providing excellent customer service. Our system is back up and running and we couldn't be happier with this purchase. Thanks!

Had to repair disk errors after a couple months of use when the drive suddenly became inaccessible on my network server for no obvious reason. Not too happy about that. But still working after a disk scan and repair (and being backed up just in case). I don't like feeling unconfident about large disks with lots of data. Update 6/1/18: Problem happened again. More bad sectors (growth errors) found. I'm trying to return it but Amazon says return expired a month after purchase. I tried to RMA via HGST but S/N came up not eligible. What the heck is happening here. I contacted the seller to see if the could help with a replacement or return. Really Amazon?!? Update 6/2/18: Got a hold of Amazon rep via online chat (buried but it exists) and they made an exception to their return policy and will refund the drive. Kudos to Amazon Customer Support! NewTronic Systems also sent me an email willing to fully refund. Great customer support again! Apart from having to restore the data with a backup, I'm happy but the drive still gets the lowest rating possible for failing.

Came same day and works exactly as described. SMART shows the drive as new and I was able to rebuild my 4 drive RAID 6 in about a day. No issues so far, quiet and cool.

Initial impressions are one thing, we'll see how longevity is. The write speed is crazy fast! I have all SSDs in my system aside from this (using it as an archival/backup disk 4TB) and it keeps up pretty well. The only thing I found weird was that the disk had a bunch of volumes/partitions on it when I put it in. Windows showed it as 3 drives. I had to do some work to kill / merge all the volumes and get it all set up properly. I worry that's a sign this was a refurbished drive being sold as new. Anyway, we'll see how it holds up, I'll drop another review in a few months.

hard disks need to be large, invisible after installed, and reliable. I can say that the first 2 are true with this disk. I guess I would have to update this review when the disk fails to answer the 3rd point.

Received two 4TB HGSTHUS726040AL4210. Both manufactured in 2015. My SAS controller (LSI 9211-8i) was not able to initialize the disks in Windows disk management with the 4kn block size. After formatting with a 512 byte block size, the drives initialize in windows with a 3.63 TB capacity. SMART data shows about 2.5 years of power-on time. Good cheap storage for the home lab if you know what you're doing.

Ordered the 8TB HUH728080ALE600 from NEWTRONIC SYSTEMS. Sure am glad that I promptly tested it. When I first put it into my Synology NAS, I thought I had a fan going out. Then, after plugging in the drive to an external SATA power/data connector, I quickly realized that the drive itself was making a grinding noise as it attempted to spin up several times. Yes, GRINDING. In all of my days as an IT Professional (25+ years), I've never come across a drive that was in such bad shape as to make this grinding noise. I'll try to upload a video so you can see/hear it for yourself.....

In the name of this drive it says that it is a sata drive but it isn’t. Theses are sas drives and they do not work like normal. I thought my first order was shipped wrong and that they sent me sas instead of sata but the second order was the same thing. If you are looking for a hard drive for your computer do not buy this, it is mislabeled. But if you are setting up a server these are a good price.
