MZWL615THBLF-00B07

15.36TB of unformatted capacity (the document’s own decimal notation: 1 TB = 10^12 bytes) in a 2.5″ U.2 form factor on PCI Express Gen.5 x4, from Samsung’s PM9D3a datacenter NVMe family. LBA count 30,001,856,512; at 512 B per LBA this is our arithmetic back to 15.36 TB decimal.

What this document says about grade

The document specifies an operating (case) temperature of 0 ~ 70 °C and a non-operating range of -40 ~ 85 °C, and it carries no industrial or vehicle-grade qualification statement anywhere; we make no such claim. Every page footer carries a Samsung CONFIDENTIAL marking — this profile publishes only the derived parameters above with per-figure provenance and does not host the file.

Provenance

Every figure above is taken from Samsung PM9D3a NVMe U.2 Datasheet Rev. 1.3, May. 2024（71 页 · md5 b84907979b50fce80a00230ace6f42cc · p7 订购表五码 -00B07 系）, a channel-local copy whose PDF /Info identifies a Samsung-internal production file (FrameMaker 17.0.1 / Acrobat Distiller 23.0). No byte-identical manufacturer-hosted public copy has been verified, so the manufacturer datasheet button is left unpopulated; the manufacturer product-family page (semiconductor.samsung.com/ssd/datacenter-ssd/) is cited for the family description only, not for any numeric figure on this page.

Ordering variants

The ordering code MZWL615THBLF-00AW7 is a channel/distribution ordering suffix of the same hardware configuration documented on this page: per the supplier chain verification of 2026-10-14, the hardware, firmware, NAND, PCB, electrical, performance, mechanical and endurance figures are identical, and Samsung does not publish channel suffixes in its public datasheet part lists (the public part table carries only the -00B07 bulk code). No independent public corroboration of the -00AW7 line has been found; the claim is recorded at supplier-verification level. Mind the form-factor prefix when building a BOM: MZ3L… denotes the E1.S/E3.S form factors of the same generation, MZWL… the 2.5-inch U.2.

Who makes it

PM9D3a is a datacenter NVMe SSD family of Samsung Electronics Co., Ltd. The manufacturer’s datacenter-SSD family page describes PM9D3a as a PCIe 5.0 x4 drive available in 2.5-inch U.2, E1.S and E3.S form factors with enhanced power-loss protection and OCP 2.5 compliance. This profile documents the U.2 variant per the U.2 datasheet only; the family page’s E1.S/E3.S figures are not used here.
