About this deal

The three 12Gb/s SAS models are the ST16000NM002G (standard), ST16000NM004G (SED) and the ST16000NM009G (SED-FIPS (Federal Information Processing Standard) ). The system connects to our Supermicro SSE-X3348TR switch with both 10GbE and 40GbE connectivity. The workload comes from a modified Quanta (QCT) MESOS CB220 server.

TrueNAS Scale for beginners: https://www.truenas.com/community/resources/welcome-to-truenas-scale-beginners-intro.208/ 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 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.When you register your IronWolf or IronWolf Pro, you trigger Seagate's Rescue Data Recovery Service. This is a free feature for the IronWolf Pro series for two years and an optional add-on for IronWolf and Exos X.

Terminology and Abbreviations Primer: https://www.truenas.com/community/threads/terminology-and-abbreviations-primer.28174/ Power supplies: https://www.truenas.com/community/resources/proper-power-supply-sizing-guidance.39/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. 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. Server Workloads There are many data points to go over in the specifications that explain why Seagate offers three NAS-optimized models. We will be starting with the IronWolf and IronWolf Pro from the Guardian Series of consumer and prosumer products.

Hardware recommendations: https://www.truenas.com/community/resources/hardware-recommendations-guide.12/ 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. In reply to Prasanga : Noise levels of X18 and X16 are same as per the manual. They both have 3.2 to 3.4 bels during performance seek and 2.8 to 3.0 bels during idealWe start to see significant performance variation in the random workloads. The first thing you will clearly notice is the Exos walking away from the two IronWolf models and in some workloads double and tripling random read performance. Less obvious is the IronWolf outperforming the IronWolf Pro. For many, this is unexpected, but we've noticed the IronWolf performing better in some workloads over the years with other capacities.
