![]() ![]() Their rated latency is 10 µs (microseconds) for both reads and writes. Intel rates the Optane SSD DC P4800X Series at 2500 MB/s for sequential reads, 2200 MB/s for sequential writes, and 550,000 IOPS for both reads and writes. ![]() Intel Optane SSD DC P4800X Specifications For low-latency workloads, there is currently nothing that comes close to the Intel Optane SSD DC P4800X. They have consistent read response times under a very heavy write workload, and unlike traditional NAND flash drives, there is no loss of performance with smaller capacity drives compared to larger capacity drives from the same product line. They also have higher write endurance than “write-intensive” enterprise NAND flash storage, and their performance does not deteriorate as they are close to being full. Intel Optane SSDs have roughly 10X lower latency and 5-8X better throughput at low queue depths compared to the fastest PCIe NVMe NAND-based SSDs. The SSD DC P4800X's high performance at low queue depths makes it a much easier drive to get very high real-world performance out of, especially for SQL Server usage. Intel's 3D XPoint storage technology is fundamentally different from traditional NAND flash. All of these drives use a PCIe NVMe 3.0 x4 interface, and they come in two different form factors, the first being a half-height half-length (HHHL) add-in card (AIC) that goes in a PCIe expansion slot, and the second being a U.2 15mm form factor for 2.5” drives that connect via PCIe 3.0. ![]() Intel has also recently released a 1.5TB version of this drive that is still hard to get in the retail channel. The Intel Optane SSD DC P4800X Series was introduced in Q1 of 2017, initially with a 375GB capacity and later with a 750GB capacity being released later in 2017. ![]()
