Solidigm SSDPF2KX038T11Z 3.84TB NVMe PCIe 4.0 U.2 Read Intensive SSD D7-P5520

The Solidigm SSDPF2KX038T11Z is the 3.84TB D7-P5520, a PCIe 4.0 x4 NVMe SSD in the 2.5-inch U.2 form factor at 15mm height. The D7-P5520 line started under the Intel name before the business moved to Solidigm, so some listings still say Intel. Solidigm's change notices list this ordering code as the generic, no-Opal, single-pack version of the 3.84TB U.2 drive. It uses Solidigm's 144-layer 3D TLC NAND.

Solidigm classes the D7-P5520 as a standard-endurance, read-intensive drive rated at one drive write per day for five years. For the 3.84TB model, Solidigm quotes about 1,000,000 random 4K read IOPS and 200,000 random write IOPS, and resellers list sequential speeds of up to 6,700 MB/s read and 3,600 MB/s write. That makes it a good fit for virtualization, general-purpose database servers, content delivery and AI data pipelines that mostly read. If you rewrite most of the drive every day, the D7-P5620 mixed-use line is rated for three drive writes per day.

U.2 drives need a bay wired for NVMe, either a dedicated U.2 NVMe backplane or a tri-mode bay that supports NVMe. A U.2 drive will not run on a SAS-only or SATA-only backplane even though the connector looks similar. The drive ships bare. OEM servers need the vendor's carrier, and their tools may report the firmware as third-party. Solidigm quotes about 15W of average active read power for this capacity, so check airflow in dense chassis.

Before ordering, check:

• That the bay supports U.2 NVMe and fits a 15mm drive.
• Whether you need TCG Opal encryption. This SKU has none.
• That your server firmware and OS support PCIe Gen4 NVMe.
• Carrier and tray requirements for your chassis.
