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. 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. Before we images of Austin Power's laser sharks dancing in our heads, we get to talk about the current product lines that just expanded capacities to 16TB. Seagate's three NAS-optimized series, IronWolf, IronWolf Pro, and Exos X now ship in the new capacity. Other than the label, the three series look identical and often times pricing is similar. Today we will look at what differentiates the three and then see each in action over in the native environment, over a network.

Lyve: Periferie-naar-cloudplatform voor massaopslag Lyve Cloud: Voordelige objectopslag, ontworpen voor de multicloud We 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. Both have the same workload (550TB per year), reliability (2.5 million hours MTBF), warranty (5 years limited), and of course the same capacity. The IronWolf Pro has the same capacity advantages over the Red Pro, and the dollars per gigabyte value is favorable, as well. The series works better in large disk deployments that exceed the recommended drive count of the base IronWolf. Seagate recently increased the maximum recommended number of drives to twenty-four from sixteen and that increases the series' usefulness for cold storage.Considering these are enterprise drives I'm thinking they could run a fair bit louder but I'm hoping for some actual data.
A 6 Gb/s SATA drive attached to an HP 420i controller will operate at 3Gb/s if the controller is dual-ported, but the drive is single-ported. A dual-port 6 Gb/s SAS drive on the same controller will run at 6 Gb/s. Hardware recommendations: https://www.truenas.com/community/resources/hardware-recommendations-guide.12/Secondly, the ST16000NM000J has a slightly higher data transfer rate ( 258MB/s) compared to the ST16000NM001G ( 249 MB /s) due to the higher density.

Seagate has two standard drives that are 16Tb. One is X16 series, while the other is X18. The data sheet on the X18 says it is CMR, but the data sheet for the X16 does not. Big Green Man Is the faster SAS continuous write because it has more data channels it can use? Both drives state they max out at 261 MB/s, when SATA is 6Gb's or 750 MB/s. With that in mind, how can SAS be any faster for continuous writes, if I'm still not filling up SATA's bandwidth (I'm not even half way)? I would be using (at least some of these) for video surveillance so continuous writes is actually quite important for me.

With the introduction of the X18 platform, Seagate introduced a new part number for 16TB Exos drives - ST16000NM000J. It's not much different than the X16 ST16000NM001G 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 ideal ST16000NM002G. Assuming the machine has the capability to run both SATA and SAS. All the articles I seem to read appear to be wrong (outdated). There's a lot that state one drive prioritizes speed, while the other capacity. One has better reliability than the other, etc. While this info may have been true in the past, it seems to be wrong now. Here is Seagate's datasheet Opens a new window on the two drives.
Maak een einde aan de kosten en complexiteit van het opslaan, verplaatsen en activeren van gegevens op schaal. 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.Failing that what are peoples experiences with noise level of these drivers compared to 8TB WD reds? 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. TrueNAS Scale for beginners: https://www.truenas.com/community/resources/welcome-to-truenas-scale-beginners-intro.208/ 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.
