Seagate IronWolf Pro 16TB NAS Internal Hard Drive HDD – CMR Inch SATA 6GB/S 7200 RPM 256MB Cache for Raid Network Attached Storage, Data Recovery Rescue Service (ST16000NE000)

Product Information

RAID performance optimized that maximizes responsiveness and uptime with NAS-aware Error Recovery Control The next benchmark tests the drives under 100% read/write activity, but this time at 8k sequential throughput. In iSCSI, the 16TB IronWolf Pro hit 128,123 IOPS read and 55,688 IOPS write, while CIFS saw half the IOPS in read performance with 62,165 coupled with 43,612 IOPS write With average latency at 8k 70/30, the 16TB IronWolf Pro showed a range of 10.1ms through 447.9ms in iSCSI, while CIFS showed a range of 6.84ms through 179.93 in CIFS, the latter which was again the best-performing configuration.

We're focusing on the 12TB IronWolf, but the 10TB model tags along for the review. Both share the same performance specifications. The four high-capacity 7,200-RPM models provide 210 MB/s of throughput. The remaining four drives deliver 180 MB/s of throughput due to their 5,400-RPM spindle speeds.

Externally, it appears to be identical to every other Seagate IronWolf drive in the 3.5-inch form factor. We should mention that this definition of workload isn’t unique to Seagate, it’s the same for Western Digital drives, and their workload amounts aren’t different for the Red Pro 20TB.

Seagate brought its 20TB products to market alongside Western Digital, eliminating any special bragging rights on this scale of drive.Our next test shifts focus from a pure 8k sequential 100% read/write scenario to a mixed 8k 70/30 workload. This will demonstrate how performance scales in a setting from 2T/2Q up to 16T/16Q. In CIFS, the 16TB IronWolf Pro started at 582 IOPS while ending at a leading 1,415 IOPS in the terminal queue depths. In iSCSI, we saw a range of 395 IOPS to 571 IOPS.
