Capacity and form factor

The Solidigm D7-P5520 delivers 15.36TB in the E1.L 9.5mm ruler form factor. It is built for dense server chassis that accept this specific length and thickness. Buyers needing a 2.5-inch U.2 or U.3 drive cannot use this model.

PCIe 4.0 x4 interface limits

The drive connects through a PCI-Express 4.0 x4 link, capping throughput at the lane speed of that generation. Systems limited to PCIe 3.0 will reduce sequential and random performance accordingly. Boards without an E1.L connector or without bifurcation for x4 lanes cannot host the drive.

Build quality and daily implications

The 144L TLC 3D NAND is rated for 28.0 PBW endurance with a 2,000,000-hour MTBF. Opal security encrypts data at rest without host software overhead. Idle power sits at 5W and active power at 20W, so thermal planning must account for sustained write workloads in a 0°C to 70°C operating range.

Questions sur cet article

Should I pick the 15.36TB E1.L 9.5mm version or a smaller capacity for my server?

The 15.36TB model delivers 28.0 PBW endurance and 1,000,000 random read IOPS, making it suited for heavy read-intensive workloads where maximum capacity per drive bay matters.

What does the 7100 MBps sequential read figure mean once the drive is installed in a real system?

That 7100 MBps is the peak PCIe 4.0 x4 throughput; sustained speeds will depend on your controller, queue depth, and thermal conditions inside the chassis.

How does the PCIe 4.0 x4 interface limit performance in practice?

The x4 link caps theoretical bandwidth at roughly 8 GBps, so the drive's 7100 MBps read and 3700 MBps write ratings sit within that ceiling.
