Intel Optane D4800X 1.5TB U.2 SSD

This Intel Optane D4800X is a 1.5TB internal solid-state drive built for enterprise workloads. It uses a 2.5 inch U.2 form factor and connects via PCI-Express 4.0 x4. The drive targets data-intensive applications requiring high random access performance.

PCI-Express 4.0 x4 interface limits

The drive operates on a PCI-Express 4.0 x4 interface, which sets the maximum throughput ceiling for sequential transfers. Sequential reads reach up to 2400 MBps while sequential writes reach up to 2300 MBps. Random 4KB reads hit up to 550,000 IOPS and random 4KB writes up to 520,000 IOPS. Active power draw is rated at 25W.

1.5TB capacity decides fit

The single specification that determines suitability is the 1.5TB capacity. It must match the storage space required for the target dataset or application. The drive also carries a 2,000,000 hour MTBF rating for endurance assurance.

Questions about this item

What capacity should I choose for the Optane D4800X?

The drive is offered in a single 1.5TB capacity, so there is no alternative size to select for this model.

What does the 2400 MBps sequential read mean in a real system?

It represents the peak throughput the controller can deliver over a PCIe 4.0 x4 link; actual speed depends on workload, queue depth and platform cooling.

Which interface standard does the U.2 drive use and what does it limit?

The drive uses a PCIe 4.0 x4 NVMe connection, capping maximum bandwidth to the electrical limits of that generation and lane count.
