Enterprise 3.84 TB NVMe SSD

The Crucial MTFDKCB3T8TFR-1BC15ABYYR is a 2.5 inch U.3 internal solid-state drive built for enterprise workloads. It delivers up to 6800 MBps sequential read and 5300 MBps sequential write over a PCIe 4.0 interface. Hardware-based TCG Opal 2.0 encryption and TAA compliance address strict data-security and procurement requirements. Endurance is rated at 7300 TB with 1 drive write per day.

Suited for write-intensive servers and arrays

This drive fits 2.5 inch U.3 bays in rackmount or tower servers that need sustained random performance of 1000000 read IOPS and 180000 write IOPS. It is not intended for desktop PCs lacking U.3 backplane support or for environments that require higher than 1 DWPD endurance. Buyers needing a different physical connector or a consumer-grade cost structure should evaluate other form factors.

PCIe 4.0 x4 NVMe interface decides fit

The single specification that determines compatibility is the PCIe 4.0 NVMe interface presented through the U.3 connector. The host system must provide a U.3 or U.2 bay wired for PCIe 4.0 x4 and support NVMe command sets. Without that exact interface the drive cannot be installed or will fall back to lower speeds.

Questions about this item

Does the Crucial MTFDKCB3T8TFR-1BC15ABYYR include a heatsink or mounting bracket, or must they be purchased separately?

The drive is supplied as a bare 2.5-inch U.3 module. No heatsink, bracket, cables or screws are included; any mounting hardware required by your server or enclosure must be sourced separately.

Should I choose this 3.84TB model or a different capacity for a write-heavy enterprise workload?

This 3.84TB unit is rated for 1 DWPD and 7300 TB total bytes written. Select a larger capacity only if your daily write volume exceeds the 3.84TB endurance budget.

What does the 6800 MBps sequential read figure mean once the SSD is installed in a PCIe 4.0 server?

In a PCIe 4.0 (NVMe) slot the drive can sustain up to 6800 MBps sequential read and 5300 MBps sequential write, with 1000000 IOPS random read and 180000 IOPS random write at 4 KB block size.
