abunda_amazon_reviews Title line says explicitly 4TB 7200 RPM. I noted a drive going down on my Drobo and ordered on Sunday; Amazon had it at my door before I left for work Monday am, so that was amazing... but that also led me to quickly insert it to start rebuild before I left for work. It estimated 10 hours so it would be done by the time I got home. Now home it claims 4 hours left and Drobo says it is really 5800 RPM. Checking my order again, indeed the title claims 7200 for the 4TB, but lower in the ad section where it says in large text 7200 in smaller text underneath is says 5900 for 'lower capacity' versions. Finally in the product comparison it claims it to be 5900. It however is not even 5900, but rather 5800. Now I've got this inserted and nearly merged into the RAID data set, so it remains to be seen whether Amazon will agree to take it back. Were I to leave it there it would compromise the performance of the box for as long as it remained in place, so that is not much of an option. Perhaps I will let it finish and then do a disk benchmark to quantify the slowdown before deciding, but very unhappy with the situation.;;Reviewed in the United States on May 20, 2019;;2.0 out of 5 stars;;Not 7200 RPM!

When benchmarking the disks I found the latency to be ridiculously high. I am assuming this is due to how the drive handles the advertised endurance. It is constantly in the 0.003 second range. Compared to the Intel at 0.0003 seconds. Even my basic consumer ADATA and Samsung drives hit 0.0007 seconds. I am sure the drive is great for everything else, but for sync writes it is not near good enough. If you see something I did wrong let me know, I would love for these drives to work. === START OF INFORMATION SECTION === Device Model: ZA480NM10001 Serial Number: --- LU WWN Device Id: 5 000c50 03ea0daeb Firmware Version: SF44011J User Capacity: 480,103,981,056 bytes [480 GB] Sector Sizes: 512 bytes logical, 4096 bytes physical Rotation Rate: Solid State Device Device is: Not in smartctl database [for details use: -P showall] ATA Version is: ACS-4, ACS-2 T13/2015-D revision 3 SATA Version is: SATA 3.3, 6.0 Gb/s (current: 6.0 Gb/s) Local Time is: Mon Oct 21 08:07:46 2019 PDT SMART support is: Available - device has SMART capability.

NOT 7200 RPM as the headline claims: fix your posting!
NOT 7200 RPM as the headline claims. They are 5900 RPM. If you really dig into the specs it says 5900 RPM in a few places Otherwise seem to work OK, but it’s only been 1 day

Stated 7200 RPM Drive speed is false!
The IronWolf 4TB Drive speed is actually 5900 RPM according to actual Seagate IronWolf specifications. Only IronWolf drives equal to or greater than 6TB are 7200 RPM. If speed is an issue then get the larger drives.
