For those looking at density, Seagate is shipping new 20TB drives. We are slowly getting new capacity tiers. Recently we covered Western Digital 20TB ePMR Hard Drives with OptiNAND and WD Gold 16TB 18TB and 20TB models. Seagate is now getting into shipping 20TB hard drives with a duo intended for storage servers and NAS gear.
Seagate Exos X20 and IronWolf Pro 20TB HDDs Shipping
In search of more capacity, Seagate announced that it will be shipping two 20TB drives this month, just making it in 2021. For higher-end NAS units, there is the IronWolf Pro 20TB drive. For larger storage servers, there is the Seagate Exos X20.
The Seagate Exos X20 is available in 18TB and 20TB capacities with both SATA 6Gbps and SAS 12Gbps models available. Here is the spec sheet for these:
The Seagate IronWolf Pro 20TB is part of the performance-optimized NAS line. That is different segmentation from the Exos X20. The Exos X20 is more for storage servers and arrays. The IronWolf Pro 20TB falls into the category of personal NAS storage at Seagate. Here are the specs for the IronWolf Pro:
Both have a maximum sustained transfer rate of 285MB/s, but the IronWolf Pro does not have a SAS3 option. One interesting note is that the AFR reliability rating of the Exos drive is much higher and it also uses considerably less power.
Pricing is set to be $669.99 for the Exos X20 20TB and $649.99 for the IronWolf Pro 20TB. Those are list prices and we have seen supply challenges mean that drives do not always sell for list. One of the biggest benefits we tend to see is that as new capacity points become available and somewhat competitive it sometimes pushes down prices of lower capacity drives. We hope that is the case with this new release.
