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

One surprise was that considering the performance improvements, we had expected the 20TB drive to pull more power and generate more heat. Seagate's AgileArray technology is a suite of features designed to provide a better user experience. Here's how the company describes the features: Seagate's IronWolf comes in eight different capacities, and that's not counting the IronWolf Pro lineup. Seagate only uses helium with the two highest capacities, while the 6TB to 12TB models are the only drives with a 7,200-RPM spindle speed. Those models also have the best UBER (uncorrectable bit error) rating. Rotational vibration (RV) sensors are the biggest dividing line for the IronWolf series. The 3TB, 2TB, and 1TB drives don't come with RV sensors, which can hamper performance in a large array.

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. Drive balance with Rotational Vibration (RV) sensors manages multi-bay vibration for long-term consistent performance and reliabilityCrystalDiskMark: 286.8MBps (read); 279.3MBps (write) Atto: 277.89MBps (read, 256MB); 274.68MBps (write, 256MB) Seagate brought its 20TB products to market alongside Western Digital, eliminating any special bragging rights on this scale of drive. IronWolf Health Management in compatible NAS systems continuously helps to safeguard the health of your data When we first saw these numbers, they sounded reasonable because the workload value isn’t like a TBW number on an SSD, as the 300TB is for each year of operation up to five years. Recovery. In the event of failure, rely on a secure environment for data recovery with Seagate® Rescue Data Recovery Service (2-year service included with IronWolf Pro).

RAID performance optimized that maximizes responsiveness and uptime with NAS-aware Error Recovery ControlThe standard deviation latency results, the 16TB IronWolf Pro 720.78ms (CIFS) and 584.24ms (iSCSI) in the terminal queue depths.

Divide that by the capacity, and the total bytes transferred is only 75TB per TB of capacity.
