Burn-in and testing: https://www.truenas.com/community/threads/building-burn-in-and-testing-your-freenas-system.17750/ The three 12Gb/s SAS models are the ST16000NM002G (standard), ST16000NM004G (SED) and the ST16000NM009G (SED-FIPS (Federal Information Processing Standard) ).

FWIW, I also have 8 Exos 16TB drives in my NAS, and it's been in service (as my home NAS) since early 2020, with no drive failures (they're currently hanging off an LSI 9211-8i SAS HBA flashed with P20 IT firmware). I haven't seen that either. Other than one drive I had replaced under warranty, the rest of the drives in my array have Load_Cycle_Count values around 1300 with over 21000 power-on hours.

Random 4KB mixed workloads, and the 70% read test, give us a good indication of virtualized desktops running off-network storage. This, as well as database and miscellaneous cloud storage, are where the Exos X stands tall. The two IronWolf products still perform well for their respected markets. Most IronWolf drives simply fall into mass storage roles hold cold data for end-users be them consumers, creators, or businesses.

I'm considering buying them as well, so very interested!

Don't use RAID: https://www.truenas.com/community/r...bas-and-why-cant-i-use-a-raid-controller.139/ As with most of the Exos product range, the X16 is available with either 6Gb/s SATA or 12Gb/s SAS interfaces. There are two SATA models, the standard model (the drive we are reviewing here) which is the ST16000NM001G – and then there is a SED (Self-Encrypting Drive) version, the ST16000NM003G. The Exos X doubles the IOPS in every OIO compared to the two IronWolf series. This doesn't come as a surprise since this is the series' home turf. Seagate has recently refreshed the IronWolf and IronWolf Pro NAS product lines with new 16TB flagship drives. Launched at the same time was the new 16TB flagship drive for the enterprise range, the Exos X16. At launch, the Exos X16 drive is the world’s highest capacity 3.5-inch 7,200 RPM drive for the enterprise sector that is readily available.Terminology and Abbreviations Primer: https://www.truenas.com/community/threads/terminology-and-abbreviations-primer.28174/

ST16000NM001G is on the X16 platform (the highest capacity on X16). It has 9 disks with 18 heads, each disk about 1.8TB. CPU: Intel Xeon E-2288G (Coffee Lake-R) 3.7 GHz (w/iGPU transcoding after TrueNAS 12.0-RELEASE upgrade)Secondly, the ST16000NM000J has a slightly higher data transfer rate ( 258MB/s) compared to the ST16000NM001G ( 249 MB /s) due to the higher density.

The mixed workload and 70% read charts show us more of the performance inconsistency at very high queue depths. These are worse case numbers for HDDs since the heavy workloads compounds latency between each IO. The two IronWolf Series drives outperform the Exos X slightly in the sequential read test, but there are plenty of outliers with all three series. BigPool: 8 * Seagate Exos 12TB HDD in 4 * mirrored pairs + 2 18TB Toshiba MG08 + Optane 900P as SLOG + Mirrored Special (800GB Intel DC S3610) Hard disk drives deliver inconsistent performance under heavy workloads compared to enterprise solid state drives. The sequential read charts shows us that as we pull data from the arrays with increasing intensity. Each dot represents an IO on the chart. The 1TB to 4TB IronWolf models use 5,900-RPM platter rotation, but the 6TB and larger capacities shifted to 7,200 RPMs just like all capacities of the IronWolf Pros series. The IronWolf base model competes head to head with Western Digital's Red (base series) that still uses the 5,900-RPM spindle speed. The IronWolf Pro is the direct competitor to the Red Pro series with 7,200-RPM speed. The advantage becomes very clear in the user experience and performance.
