I purchased 5 of these for use in in a Synology 1522. As others have warned, you get a warning message but after accepting, the Synology shows these as healthy and has no issues using them. Write performance in a RAID 6 has no trouble maxing a 1GbE connection. I’m sure 2.5 would be no issue. Internal read/write speeds during the array build were 1.3GB/s so each drive was yielding about 250MB/s.I did have one arrive DOA. B&H exchange for a replacement was painless. Once the replacement arrived, no issues.Other reviews have commented on noise. These are quiet as compared to the 6 - 16TB Exos drives in my 1621. I’m sure in a dead silent room these have mechanical noise but this shouldn’t be noticeable if placed in a closet or out of the way.Overall, I’m very ... MoreI purchased 5 of these for use in in a Synology 1522.

As my old NAS was getting ready for retirement, I decided to replace it with a newer Synology (DS1522+). The old NAS has 4 HGST enterprise drives that I bought refurbished on Amazon. They've been reliable and awesome for a little more than 3+ years, but they were so loud! I've had various configurations of drives in the NAS over the years, and these are the brands I've previously tried:BTW, I only recently read that it's recommended to stick with a single brand for drives...not sure how much it affects things, but maybe that's why I've had mixed results in the past?*WD - didn't have much luck with them, both of them died within a year and at the same time (don't think I'll ever try them again).*Samsung - surprisingly pretty good...they eventually were replaced ... MoreAs my old NAS was getting ready for retirement, I decided to replace it with a newer Synology (DS1522+).

I was looking at total price, price/TB, noise level, reliability, power draw, and warranty. Seagate seemed to come out on top vs. Synology and Toshiba.One of the things that concerned me was the reported noise levels; I'd read the Pros are really loud, but when looking at the spec sheets, their numbers were much lower than the non-Pro versions. After having lived with these for a couple of weeks, they are so much quieter than my HGST drives. So far, really happy with them and hopefully they'll hold up.

I spent A LOT of time reading reviews about god knows how many internal hard drives and racking my brain about which brand or product to go with. I'm happy I settled on this Seagate 16TB NAS. In terms of cost vs. storage capacity, I learned that the 16TB size drives are usually the most cost-effective and give you the most bang/storage for your buck. Go lower or higher storage capacity, and you end up paying a, overall higher per TB cost. I bought a new OWC Thunderbay 8-Bay and installed 8 of these new drives into my Thunderbay. Only did so yesterday so I can't really attest yet to the quality of the drives. But so far they are very quiet, and as I'm copying over vast amounts of data right now to these drives, they appear pretty darn fast too. So I am loving them. ... MoreI spent A LOT of time reading reviews about god knows how many internal hard drives and racking my brain about which brand or product to go with.

I ordered a pair of these recently due to them being on sale.I had to return the first pair as they were completely DOA on arrival. And we're not talking "I stuck them in once, and that was it" kind of testing.I seated and re-seated each one in a test slot and neither would even start spinning. I took my NAS offline and cleaned it thoroughly and even tried wiping contacts down with rubbing alcohol.I tried both new IronWolf Pro drives in multiple other computers and even tested additional drives I had lying around to make sure it wasn't maybe the hot-swap drive bays malfunctioning somehow.Every single test failed.So I started a return. After a short call to make sure I wasn't messing up somehow, the process to ship them back and have new ones come replace ... MoreI ordered a pair of these recently due to them being on sale.I had to return the first pair as they were completely DOA on arrival.

After a short call to make sure I wasn't messing up somehow, the process to ship them back and have new ones come replace was relatively easy.The 2nd pair shipped to me worked no problem.I have a Synology DS1520+ that I've been slowly replacing the 5 original 6TB WD Red Pro drives with upgrades as they fail (or run out of space).The features the iron wolf pro drives have are much better than the WD drives. The IronWolf Pro drives are recognized with more useful information by the Synology system. The WDs came up as "generic" in the drive inspector application. There are special testing features that do not exist for the WD drives.Overall the IronWolf Pro drives themselves are 5 stars. The only reason I took a star off was for the hassle of having to do the return as a result (I'm assuming due to the absurdly rare instance of 2 brand new drives being completely DOA) of shipping probably handling them really roughly, causing some sort of failure - even when the drives come packed in bubble wrap, anti-static bag, and other protective packaging.Thanks B&H for making it as easy as realistically possible to return the bad drives and replace them! I continue to come more and more to your business as opposed to many other electronics retailers due to the great level of customer service you maintain!
Bought 2 18tb internal drives direct from Seagate, they are fast and QUIET. They were carefully packed in appropriate cartons and operate without issues. I bought the 2 previous drives (16tb & 18tb WD external) from Amazon. One shipped in the box that is normally displayed on the shelf in a store, nothing else. It was only protected by 2 pieces of plastic and sounds like a box of rocks. The other shipped loose in a large carton and sounds just as bad. They are slow to respond and stutter, rattle, shake (!) and can be heard in the next room. I have never had these issues with ANY drives before (I've bought dozens) and can't help but attribute this to the terrible packaging they were shipped in. Thank you Seagate for your careful packaging! BTW, I have been buying ... MoreBought 2 18tb internal drives direct from Seagate, they are fast and QUIET.

I've tried mainstream regular and NAS drives from Toshiba, Western Digital, Hitachi, IBM and Seagate over the past 30+ years, but either because of reliability, especially reliability, tech support, or price keep coming back to Seagate.Seagate has consistently had great tech support and been easy to deal with and this IronWolf PRO series, not the plain IronWolf non-pro series, are by far, the best conventional hard drives I've ever encountered.I have about 25 of them mostly 8TB, 16TB and 20TB which I've purchased over the past few years. All are still going strong and many run 7x24. All have been excellent values and I've never had a problem with any of them.They have a 5 year P&L warranty but only if purchased from an authorized Seagate source.They usually ... MoreI've tried mainstream regular and NAS drives from Toshiba, Western Digital, Hitachi, IBM and Seagate over the past 30+ years, but either because of reliability, especially reliability, tech support, or price keep coming back to Seagate.Seagate has consistently had great tech support and been easy to deal with and this IronWolf PRO series, not the plain IronWolf non-pro series, are by far, the best conventional hard drives I've ever encountered.I have about 25 of them mostly 8TB, 16TB and 20TB which I've purchased over the past few years.

All have been excellent values and I've never had a problem with any of them.They have a 5 year P&L warranty but only if purchased from an authorized Seagate source.They usually have no warranty if they are purchased from an OEM, an Original Equipment Manufacturer. OEM's are usually mainstream manufacturers who buy pallets of hard drives which they use in their products.When models change, OEMs might keep some for of those drives for service, but usually their remaining inventory is sold to the grey market, a mixture of smaller computer dealers and liquidators. Even if the drives your buy from such sources are sealed and are brand new, because they were originally sold to an OEM, Seagate won't honor the drive's warranty and you are on your own to get it serviced or replaced.You can find out a Seagate's drive warranty by entering its serial number on the support section of the Seagate website. I always check the serial numbers there before putting a drive in service.I've never had an issue with HDs I've sourced through B&H or for that matter any issue I've had with B&H with anything I've bought from them in the past 40+years. They are the best store I've ever encountered.
I bought the Seagate 22TB hard disk used Nov 25, 2023. I bought the product in New York and I live in Israel. On 01/31/2024 I returned to my country and tried to use the diagnostic disk while playing, the disk made strange noises and the computer did not recognize it at all and it was also impossible to format it and prepare it for use. After that I saw that the hard disk was physically damaged as in some corners its casing was deformed. Now I'm in a problem since used ones only have a 3 month warranty and I live in another country.I would like to point out that this is the second time I have been damaged by used B&H products 2 years ago I bought a used HP laptop and it gave me problems and I opened it and saw that it had already been opened before and it was ... MoreI bought the Seagate 22TB hard disk used Nov 25, 2023.

B&H refused to help me because the 3 months of warranty had passed. Even though the computer is sold in condition 9. That's why my recommendation is not to buy a used product at the B&H store.
I recently added to my line of Synology NAS storage devides with the 1522+. I needed an offsite backup solution for redundancy. I purchased the 1522+ to replace my current 918+, used as a storage device for my videography related backups, as an offsite backup solution. The best bang for my buck at B & H for HD size was the 18TB IronWolf Pro. After setting up the two 18TB drives in BTRF format, I began to copy my archives, and current backups to the new NAS. The drives are fast and reliable, and copying went as expected. I have them set in a double drive redundancy, and can only speak to what I have intentionally set them up for. I have about 9TB of video, graphics (still and motion), and other related videography data to store, along with a Plex server running, with ... MoreI recently added to my line of Synology NAS storage devides with the 1522+.

I believe in redundancy, and this is my fourth NAS from Synology to run the IronWolf Pro series drives, and they, by far, have met my needs. I have yet to have a failed drive with Seagate IronWolf, even after a significant surge struck my original Synology 918+. I pulled the IronWolf HD's and installed them in a new 918+ and they worked like a charm. I expect long life, and lots of backups from these new HD's.
Are you joking me? I purchased this drive on April 19, 2024. I seem to remember being upset that Seagate's phone number was removed from the box. I had to drop to diskpart and dos to format the drive for Windows 11.But Seagate has never let me down; ever since the 1980s, they have been my first choice for hardware. Up till the Samsung/crucial SSDz, I sell them and seldom use any other storage devices.It contains 22 TBS OF STORAGE and can read and write at a steady pace of around two to 300 megabytes per second! It can keep EVERY picture or video file on ALL of your devices, including OS's from apple ii, amiga to win 3.11 to 11.

The one thing about the summer heat wave that worries me is that it can get really hot, so 98 degrees without air conditioning or fans could be a problem. though even that is seldom.I therefore virtually always suggest Seagate and, if the surveys are still open, I also examine updates once a year.
