    • Great drives
Capacity: 16TB
It seems a lot of these reviews get mashed together, so to be clear, this is for the SATA III (6gb/s) 16TB Seagate Exos. These run very cool (I've not seen them hit higher than 32c under heavy load, but usually stay below 30 in my system) They're not the quietest drives but they're also not obnoxiously loud and are typically only notably audible during spin-up and heavy access. I've bought a couple of these and plan to buy at least a few more once the price comes down again. If you're looking at these drives wondering what the differences are between the Exos series and the IronWolf Pro series, here's some quick food for thought: The IronWolf Pro series has typically has the same interface, cache sizes, and very comparable read/write speeds. (I've personally found the IronWolf Pro's to be a hair faster than comparable Exos drives, though the differences were very minimal.) Workload: The drives in the Exos line are rated to handle up to 550TB of reading and writing per year, while the IronWolf Pro series is only rated for 300TB per year. Data Recovery: Seagate includes data recovery services for a certain period in the warranty for IronWolf Pro series drives. This is not included by default with Exos drives and is one of the reasons the IronWolf Pro series drives may sometimes be more expensive than comparable Exos drives. Longevity: Exos Drives are rated at approximately double the MTBF(Mean Time Before Failure) as IronWolf Pro drives(~1.2 million hours vs ~2.5 million hours) Multi-Bay support: IronWolf Pro drives are rated to handle up to 24 drives in a single enclosure/raid array) while Exos Drives do not have this limitation. Write Cache technology: Some of the lower capacity IronWolf Pro series use (or at least have used in the past) have used Write-Back caching. While the Exos line pretty much always uses write-through caching. SMR vs CMR: Some of the lower capacity IronWolf Pro series use/have used SMR (shingled magnetic recording), a technology that has previously come under scrutiny for not being advertised. SMR drives are optimized for write-once read-many applications, meaning while read speeds are just fine- write speeds are typically slower on SMR drives due to the way data is written to the platters. Exos drives are always CMR and have both good write AND read speeds. If you're looking at an IronWolf drive and not sure if it's CMR or SMR be sure to check Seagate's website. ... show more

    • Library Storage Device - Awesome price point (2021) - Cool and Quiet - 4KN
Capacity: 16TB
Seagate 16TB HDD Exos X16 7200 RPM 512e/4Kn ~300 USD (2021) This has been a 100% working drive so far. It has been writing its new contents for 3 days straight now. Temperature remaining at 32 degrees C. This is Great considering I am running it at full demand for a long time. For comparison my external WDC WD100EMAZ-00WJTA0 10000.8 GB (WD My Book 10GB) has run at 48 to 53 degrees C, alarmingly hot. After this WD external is getting shucked, the enclosure dremeled open for air, or a fan physical screwed on from an old computer. Datacenter drives can be noisy and this is generally known, this drive has been whisper quiet. There are not any clicking or ticking or whizzing sounds. Mine came with SN03 firmware and SN04 was available. Updating the firmware was a pain in the ass. Nothing can be done while in windows because it blocks everything like it is a virus, thanks Microsoft. I had to boot into seagate tools and then type the one commandline. This was easy, except that it took 4 hours of searching and reading everything available online to figure out that one line!!!!!! Horrible documentaion on this, not even youtube could help. While in Seagate tools I changed my drive to 4K (4096) or 4KN logical sectors. If you do this, do it before putting data on it. The majority will not know or care about this and is not a reason to disregard buying this drive. I am traditionally a Western Digital fan. 20 some years ago I used Seagate in everything with fantastic results (I still have a couple still around shelfed as backup storage). This drive was on sale for 300 when it is normally 400. I needed a drive quickly and at a good price. NOTHING compared to it in terms of price to value ratio. This might be in part due to COVID. I have been surprised at the quality so far and may be returning to using more Seagate hard drives again. My drive is not a SED (self encrypting model) but I am running Veracrypt on it fine. ... show more

    • A review of the Exos 14tb and of Amazon's return process
Capacity: 14 TB
This 14 tb Seagate Exos was reasonably priced and available overnight. I ordered one to add space to one of my Unraid servers. It arrived the next day but was dead. Tried on 3 different computers and none of them recognized it. So I filed for a return with Amazon and dropped it off at my local Staples that handles Amazon returns. Over the years I have bought a lot of hard drives from Amazon and other places and this was the first DOA. Figuring the odds of another DOA were very small I placed another order for the same Seagate Exos 14 tb model. It arrived the next day and is up and running with no problems. Exos drives are designed as Enterprise level drives with great performance and a long MTBF. So far none of the Exos drives I've purchased over the years have given any problems other than this one DOA. Hard Disk Sentinel tests rate it as excellent for both performance and health. Amazon issued a credit to my card shortly after I dropped off the first drive. The entire return process was quite quick and convenient. ... show more
