Both HDD worked like a charm on Synology Ds1621+. Just started using it, but only for backup, not for day-to-day transactions.

I took one star off because as soon as its on my synology nas instead of giving me 12 tb it gives something like 10.5. I don’t understand why the synology or the nas takes so much space but it has worked very good so far.

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.

I have never owned a hard drive this large before but all I can say is that it is way past awesome. I do video editing professionally and this thing is a little jewel. It is extremely fast with it’s 7200rpm speed and works perfect for video production projects. I can’t believe the very reasonable price for it too. B&H is doing it right. This is a must buy if you want a lot of storage space plus something that is lightning fast.

Upgraded my Synology DS214 from 2TB to 4TB. Dropped these drives in the bays one at a time and in a few hours had my array updated. Super easy.

I bought 2 – 10 gig IronWolf Pro hard Drives and they are fast & Powerful.

I’m using this in conjunction with an NVME drive (which would be scratch) and this is more bulk storage (1 drive for storage, 1 for backup of said storage). The warranty offers a lot of peace of mind, considering the drive isn’t super cheap.

Works as expected which makes life easier. Yes it is a bit pricy but worth it. Thank you for the Super fast shipping & corrected errors.

I have many Mac clients on Synology NAS devices [mostly DS1821+ series]. Synology has special tuning for IronWolf Drives that help early detection of problems. The ONLY drives I will ever put in a Synology NAS is IronWolf Pro drives. Only exception would be the Synology Branded drives that are also excellent but harder to get and a bit more expensive. I do recommend always using SHR2 for dual drive redundancy with these drives. They are great drives, but ALL hard drives [eventually] fail. –

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.

Seems the older model number (ST8000NE0004) I ordered with my Synology DS2019+ are failing on me inside the 5 year warrantee and Seagate is replacing with this model. Seagate is not offering the rapid replacement, just the standard 2 to 3 week replacement… I am not really happy with this pro NAS specific model!

I’ve had these installed in a new PC build for 4 months – they work perfectly. It’s great to have enough room to not be worried about running out of space.

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.

Packaging well done, easily recyclable. The drive joined its 16TB Ironwolf companion in the Synology NAS. Can’t report on the noise level because the NAS is downstairs, away from my desktop. All in all, well satisfied.

I previously ordered similar drives from Amazon, but they arrived in a paper envelope(!) with no padding (!!). As a result, they were completely destroyed. The next time I decided to order from B&H. Not only I got a nice discount when ordering 2 drives, they were shipped in a box with appropriate amount of padding (each drive was suspended in individual box, boxes were padded). I am pretty happy with the drives’ 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.

Its a disk drive. At this price for a ‘premium’ drive I expect good performance. Time will tell.
