Ran 4 of these in a storage array for a few years. They replaced a similar array built on smaller SATA drives. Needless to say, they're muuuuch faster than the SATA drives.

SPEED! I tested file transfer speeds with this drive copying to-and-from a RAID0 of four 1TB Western Digital Black 64MB cache drives (all on SATA3 controllers). Initially a large file copy from RAID0 to this drive will burst up to about 450 MB/s and then slowly drop down to around 190 MB/s sustained. I also benchmarked this drive with 'HD Tach RW' benchmarking software on both SATA2 and SATA3 controllers for comparison. HD Tach SATA3 (6.0Gbps) - 340 MB/s Burst Speed - 210.7 MB/s Average Read - 194.9 MB/s Average Write - 9.1ms Random Access (Latency) HD Tach SATA2 (3.0Gbps) - 214.8 MB/s Burst - 174.0 MB/s Average Read - 155.2 MB/s Average Write - 9.2ms Random Access (Latency) Clearly this drive performs best on a SATA3 controller and maxes out a SATA2 controller. This is incredibly impressive for a single disk drive. The drive did not have a "sloping" HD Tach graph where the beginning performs faster than the end of the platters, as many do.

Works good, high capacity

Does not throttle under heavy load or copying large file.

Ran a full read/write test which took about 30 hours on each drive (2 in total). Zero issues. They are about as loud as my WD Reds. I have them in my NAS no problems.

WD makes solid drives, and this one seems to be another solid drive Comes in the OEM box with shock absorbers. Very Important!

all 4 of my 4TB Western Digital drives in my NAS failed in the last year (after warranty period ended). Replacing all 4 drives over the last 4 months. Currently Seagate has slightly better quality than W.D. These Ironwolf drives have a reasonable price and quality.

Good price 12gb interface Works well so far in my Adaptec raid 5

Got this computer up and running with this hard drive - got it for another computer and than the hard drive crashed on this one ( IT WAS A mediamax ) just quit !!

Name Brand, only 1 drive has failed in the last 4 years out of 150-200 drives installed. Def recommend.

Enough space to be able to short stroke it Max write speed 190Mb/s (edge of the disk)

The 6 TB version seemed like the best balance between price, size, performance and noise / heat. This is going in a 4 bay NVR which is in a very quiet environment. So far, these drives seem much quieter than the 7200rpm version (during seek) which are being swapped out 1 at a time to allow the RAID rebuilds to catch up. Temps are 10C lower than the 7200 pro version. (37C vs. 47-49C per SMART data.)

Saved money, and was able to get a better HDD. 5 Year warranty (vs. 1 year of one Dell wanted to sell me) Arrived pretty quick...way faster than the "estimated time".

This HDD has plenty of capacity for my security cameras. I switched from a 4TB to a 14TB and now I have months of video storage!

Drive is a better price than most consumer 6TB drive and has much better specifications. This drives is rated for 600k load/unload cycles, most other drives, even some with 5 year warranties are rated for 300k. This drive has a read error rate that is 100x better than most consumer class drives. 1 sectore per 10E15 vs 10E14 for consumer class drives like the Barracuda or WD Blue. Mean Time Before Failure of 2 million hours. Rated for a workload of 550TB per year. Annualized Failure Rate of 0.44%. Advanced Write Caching via internal NOR flash. 5 year warranty. Specifications allow for 24x7 operation of the drive. Some other drives including Seagate Barracuda are only specced for 40 hours power on time a week! 8,760 hours a year versus 2,400. This drive uses Perpendicular Magnetic Recording and not the horrible Shingled Magnetic Recording that Seagate's consumer class drives use. SMR has such a bad reputation Seagate has changed the name to TGMR, but make no mistake TGMR means SMR.

18TB capacity (16.3TB after format) SATA III (6/GBs) CMR array 1.2 million hour run rate 7200 RPM speed 256 MB cache

-This is seagate! -Cheap, powerfull and stable!
