Crucial 3.84 TB Micron 7450 PRO encrypted internal SSD E1.S PCIe 4.0 (NVMe)

SKU CH-M9JR-NQNYN

High-capacity 3.84 TB NVMe drive with PCIe 4.0 speeds of 6800 MBps read and 5000 MBps write, 1 DWPD endurance rated at 7300 TB, and TCG Opal 2.0 hardware encryption

  • Device TypeExternal Solid State Drive (SSD)
  • High-capacity 3.84 TB storage for dense server deployments
  • Hardware-based TCG Opal 2.0 encryption protects data at rest
  • PCIe 4.0 NVMe delivers 6800 MBps read and 5000 MBps write throughput
  • Enterprise endurance of 7300 TB written at 1 DWPD
  • 2 million hour MTBF with 1 in 10^17 error rate ensures reliability

3.84 TB E1.S NVMe SSD

The Crucial Micron 7450 PRO is a 3.84 TB internal solid-state drive built in the E1.S form factor for PCIe 4.0 (NVMe) slots. It includes Self-Encrypting Drive technology with TCG Opal Encryption 2.0 for hardware-based data protection.

Fits E1.S bays with PCIe 4.0 lanes

This drive installs directly into an E1.S slot wired for PCIe 4.0, removing the need for a 2.5 inch bay or cabling. Sequential throughput reaches 6800 MBps read and 5000 MBps write while drawing 12 Watt in read and 14 Watt in write, leaving thermal headroom for dense server chassis.

Replaces lower-endurance E1.S drives

With 1 Drive Write Per Day and 7300 TB total endurance, it upgrades deployments that previously hit write limits or lacked hardware encryption. The jump is worth it when workloads demand sustained 1000000 IOPS random read, 180000 IOPS random write and 80 µs latency backed by a 2000000 hour MTBF.

Questions about this item

Will the 1 DWPD endurance rating limit how long the drive lasts under heavy daily writes?

The drive is rated for 1 DWPD, which equals 7300 TB of total writes over the warranty period, so sustained workloads staying within that budget will not hit the endurance limit early.

What are the power draw and thermal figures when the SSD runs at full speed all day?

Sequential read draws 12 W and sequential write draws 14 W; the average latency is 80 µs, so sustained throughput stays consistent without large thermal spikes.

Does my server need an E1.S slot and PCIe 4.0 support to install this SSD?

Yes, the drive uses the E1.S form factor and a PCIe 4.0 NVMe interface, so the host must provide an E1.S bay wired for PCIe 4.0 lanes.
