Awesome customer service

Using 4 of these for fast raid in a 16bay NAS, they work perfectly and are built for this purpose. Long warranty, enterprise class, huge space, and good speed all at an amazing price, great buy. Don’t expect SSD speeds as these aren’t meant for fast performance.

I purchased this 16TB Hard Drive for my Synology NAS. I needed to expand my storage so I purchased 1 of this and 2 WD Red Pro 16TB. I am comparing this against several other drives I have both regular consumer and Enterprise class drives. Heat and Noise: Compared to Regular 10TB Helium Drives this runs a bit louder and a little hotter, but not as much as Enterprise class equivalents. I would not call this loud but they do make more noise than my WD Red and Red Pro’s, especially during writes. Under read loads they are all about the same. After the hard drives arrived I plugged it into an external enclosure and ran a few check to make sure it was all good before trying to deploy them in my NAS. I ran crystalDiskInfo and ran my simple performance check which includes CrystalDiskMark and an 8Gig file copy to the HDD. Seagate IronWolf Pro 16TB: Seq Read: 278 MB/s, Seq Write 273 MB/s, Copy 80 MB/s WD Red Pro 16TB: Seq Read: 266 MB/s, Seq Write 264 MB/s, Copy 259 MB/s Seagate EXOS 18TB: Seq Read: 291 MB/s, Seq Write 282 MB/s, Copy 258 MB/s WD Ultrastar HC550 18TB: Seq Read 269 MB/s, Seq Write 268 MB/s, Copy 274 MB/s WD Red Pro 18TB: Seq Read 267 MB/s, Seq Write 266 MB/s, Copy 260 MB/s WD Red Helium 10TB WD101EFAX: Seq Read 218 MB/s, Seq Write 219 MB/s Speed comparison for reference. This is just a small selection of my hard drives that I have owned and have tested. This is where I see a performance oddity. The File transfer is only 80MB/s but crystaldiskmark indicates it should be much faster. I did not return or RMA. I have seen this one other time with the Newer Non-Helium WD Red Plus’s. I figure some error happened in the copy test so the writes were not happening every disk rotation. Just a guess I didn’t rerun my test. Yes I have quite a few HDD’s for primary and backup storage.

We use these in our QNAP NAS in our editing suite. We are running 3-5 editing machines a day, all accessing the data on these drives at the same time for 5-6 days a week. We ran about 2 years before one of the drives even got a slight health risk. Highlight reccomend

Works good and speed is about 200mb so I’m able to transfer about 10 gigs in about 3 minutes. It’s fast enough for every day use. If you have 16 TB of files like me, it’s about 150Mb transfer cause of photos. I’m still very happy with it, but you don’t get 20TB of storage, I only got 18TB. I guess 2TB is lost cause it needs it for who knows what. I’ll probably get 3 more 20TB to have backup to my backup and another spare to have at a different location.

Installed 2 of these in a new Synology DS420+ NAS. Working great so far (after only 2 weeks it’s hard to review longevity of the drives :-)). Compared to other retailers, B&H ships hard drives in packaging that seems to better protect them during the shipping process. I have had to return hard drives from other retailers (who shall remain nameless) because they arrived DOA.

This drive is amazing! Fast, quiet and gave me tons of extra storage!!!

These are great drives that are running well in my Synology DS1821+ NAS. The usual B&H customer service was outstanding and it’s good to know they’re standing behind me for any support I need.

I have been slowly adding to my Synology NAS. These hard drives have been rock solid for over a year so far with no issues. All 12 disks I have received have been good and have not produced any issues or loss of data. The speed is typically for an optical drive. Wish I could afford solid state, but they don’t make large enough drives in an affordable range yet to hold this much data.

Upgraded storage on my QNAP TS-251+ from 2 TM to 8 TB. Works great, but swap out took an overnight transfer to rebuild. I put the old 2 TB drive in my workstation without problems.
Jayden Daugherty (verified owner) –
I installed these in a Synology NAS at home. They are super fast and work well. I would like them to be a tad quieter since they are in my office and I can hear them clunking as the heads seek, but spinning noise is practically inaudible. The clunking isn’t so loud that it’s annoying, but I can hear it. However, they are quieter than my old Western Digital Red drives that these replaced.

Does what it is supposed to do!

Very nice.

I own several of these 20TB Seagate IronWolf HDD’s. They are totally awesome. They are very reliable and fast. I do film and video editing for clients and these Seagate drives never let me down. There is enough storage space to back up your largest files and many of them as well as handling large 4K -8K video files. This is a must buy!

IronWolf drives have been great for me and on the only issue I’ve had, Seagate replaced the drive despite it being out of warranty.

The drive is working fine but installing it into a drobo unit was a challenge. the dimensions of the drive case are slightly different and it makes the install not quite as easy as my older smaller WD drives.
Wayne Doyle (verified owner) –
What a great, huge value. Forty years ago a 40 meg hard drive cost approximately 40 thousand dollars, and much slower access. I know, I worked as a tech for a major computer manufacturer. Now, it’s crazy to see what the Chinese have taken to incredible levels of resolution. Also, really nice packing job by B & H. You will get a fast, nicely packed brand new item. Not somebody’s return.

It works, went on sale the next day.

We put two of these into a Synology NAS, configured them for RAID1, and filled them to 60% capacity. So far, they seem to be working fine.

This is the second of these I’ve bought to help expand my drobo 5D. I’ve been quite happy with them so far!
