  • Seagate is the oldest brand hard drives and the quality lives on
Capacity: 16TB Style: HDD Pro(New)
Seagate has been around since the beginning of hard drives and has the experience to know how to make the best. When it comes to hard drives is simply makes sense to buy the best from the brand you can trust. Flawless performance for working drive or back ups. Highly recommended.

  • Storage
Capacity: 22TB Style: HDD Pro(New)
For a hdd it's pretty quick. Was averging about 325-400 Mps. Under heavy loads it runs in the 28-32 deg. C. 22tb formats out to exactly 20 tb. Pricy but worth it.

  • Needed a spare drive for a NAS and this fit the bill
Capacity: 22TB Style: HDD Pro(New)
So far so good. This was needed to replace a DOA drive I got from another vendor. It arrived quickly, and most importantly...it worked without any issues. Seller shipped quickly and it arrived when expected.

  • Bought 2 and one came falty
Capacity: 16TB Style: HDD Pro(New)
Purchased two brand-new IronWolf Pro 16GB HDDs. Unfortunately, one arrived faulty and was completely dead on arrival, not being detected by my NAS, PC, or server. The other drive is working fine without any issues so far despite being a bit noisy. Just noticed that other people had the same issue, so lowering the score since it is really a hassle to return the unit back to the states. ... show more

  • Works great but noisy
Capacity: 16TB Style: HDD Pro(New)
I bought two 16TB Iron Wolf for my Synology NAS DS220+. I had to replaced first 2 drive they arrived with dents and scratches. The seller replaced both, no issues. HDDs works great no issues so far BUT... The they are noisy when the NAS is idle. Doing my research thinking the Disks could has a problem I found the noise is something common on Seagate drives. Based on my searching it's a head parking noise and it's normal but I can hear the clicking sound around the house, looks like someone is walking on my attic lol. Rather than that everything's looks good. -1 star due noises. ... show more

  • 5.0 out of 5 stars Worked perfectly in a DS923+
Capacity: 16TB Style: HDD Pro(New)
Drives are AMAZING and worth it over consumer-grade drives. Time will tell........ Also Bought two A-Tech 16GB ECC ram sticks for my DS923+ NAS system. Have to say that I am pleasantly surprised by their performance. These ram sticks exceeded my expectations. I installed them in my DS923+ without any compatibility issues, making it a user-friendly and seamless experience. The absence of warning errors about unofficial ram further confirms their excellent compatibility with the DS923+ system. Also, these are a steal for more than half the price of Synology-branded ram. ... show more
