Optane’s Final Journey: Intel Quietly Launches P5810X SSDs


Intel has quietly started shipping its Optane SSD DC P5810X drives, which could be its latest storage device based on 3D XPoint memory. The new SSDs offer extremely high performance and ultimate durability at 100 disk writes per day (DWPD). Yet they are little different from the original Optane SSD DC P5800X series products. So what would you expect from the defunct Optane division?

Intel’s Optane SSD DC P5810X series currently includes 400GB and 800GB models that come in a 2.5-inch U.2 form factor with a PCIe 4.0 x4 interface. The drives sport performance reaches a sequential read speed of 7200 Mbps as well as a sequential write speed of up to 5400 Mbps (800 GB SKU) or 6000 Mbps (400 GB SKU) (these speeds make these drives l ‘one of best SSDs today). When it comes to random read/write performance, the drives are capable of up to 1.5M/1.38M IOPS with five µs read/write latency.

The main selling point of these drives is, of course, their 100 DWPD endurance rating, something that conventional 3D NAND products cannot offer, which is why Kioxia has XL-NAND and Samsung has Z-NAND (and still can’t match the endurance of Intel’s Optane DC).

Intel’s Optane SSD DC P5810X line belongs to the drive family codenamed Alder Stream, which already includes products from the P5800X series, so it’s logical to expect new products to use similar controllers. and 3D XPoint memory media. Meanwhile, the new P5810X drives have a considerably higher active power rating than their P5810X brethren, which on the one hand means they can withstand high temperatures for extended periods of time (yet they don’t exceed 70° C), but on the other hand indicates their lower economic efficiency.

We don’t know exactly how Intel plans to position the new P5810X SSDs against the existing P5800X drives. Intel has almost never spoken publicly about its Optane SSD DC P5810X drives. We only know of them because these devices (along with their ruler format Optane SSD DC P5811X counterparts) passed NVMe interoperability testing earlier this year at the University of New Hampshire Interoperability Lab (the leading validator of SSDs and NVMe-compatible controllers).

Perhaps the most important thing about the Optane SSD DC P5810X and Optane SSD DC P5811X is that they are probably the last 3D XPoint drives ever released by Intel, as officially announced by the company. killed his Optane business earlier this year. We have no idea how long Intel plans to ship its 3D XPoint-based products, although we’re sure the company has no plans to produce 3D XPoint devices with a PCIe Gen5 interface.
