Micron MTFDKCC3T8TFR-1BC1ZABYY 3.84TB NVMe PCIe 4.0 U.3 Read Intensive SSD 7450 PRO

The Micron MTFDKCC3T8TFR-1BC1ZABYY is the 3.84TB member of the 7450 PRO family, a PCIe Gen4 x4 NVMe drive in the 2.5-inch U.3 form factor with a 15mm z-height. It is built on Micron's 176-layer 3D TLC NAND and is the non-SED version, which means it has no self-encrypting drive feature. Micron positions the PRO line as its read-intensive tier, rated at one full drive write per day over the warranty period.

Read-heavy work suits this drive best: virtualization hosts, VDI boot images, web and content serving, analytics scratch space and database tiers where reads far outnumber writes. Micron rates it at up to 6,800 MB/s sequential read and about one million random 4K read IOPS, with 180,000 random write IOPS. If your workload rewrites most of its capacity every day, such as heavy logging, caching or write-heavy OLTP, look at the 7450 MAX mixed-use models instead.

U.3 drives follow the SFF-TA-1001 standard and use the same SFF-8639 connector as U.2. They are intended to work in tri-mode U.3 bays and in most U.2 NVMe bays, but backplane support varies by server model and generation, so confirm NVMe support for the specific bay. The drive is sold bare. Dell, HPE and Lenovo servers normally need the vendor's own carrier or tray, and some OEM management tools flag non-OEM firmware as unsupported even when the drive works.

Before ordering, check:

• Your bay supports NVMe over U.2 or U.3, not only SAS or SATA.
• The 15mm height fits your sled. The 7mm model uses a different part number.
• Whether you need encryption. The SED (TCG Opal) version is MTFDKCC3T8TFR-1BC15ABYY.
• That you have a matching drive carrier for your server.
