SanDisk Optimus GX PRO 850X 1TB NVMe SSD

The SanDisk Optimus GX PRO 850X is a 1TB internal solid state drive using the M.2 2280-D5-M form factor. It connects via a PCI-Express 4.0 x4 interface and uses 3D NAND TLC memory with an SLC cache design instead of a DRAM buffer. A heatsink is integrated onto the drive.

Suits builds needing PCIe 4.0 speeds

This drive suits desktops and laptops with an M.2 slot wired for PCIe 4.0 x4 that can accommodate the 8.9mm module height. Systems limited to PCIe 3.0 or slots restricted to single-sided modules should look at other options.

PCI-Express 4.0 x4 interface determines

The drive requires a motherboard or laptop M.2 key-M slot that supports PCI-Express 4.0 x4 electrical operation to reach the stated 7300 MBps read and 6300 MBps write peaks. Without that link width the drive will negotiate a slower speed.

Points forts

  • Sequential read speed up to 7300 MBps via PCIe 4.0 x4
  • Sequential write speed up to 6300 MBps for fast file transfers
  • Random write up to 1,100,000 IOPS for responsive multitasking
  • 600 TBW endurance with 1,750,000 hours MTBF reliability
  • Integrated heatsink maintains performance under sustained workloads

Questions sur cet article

Will the 8.9mm height of the M.2 2280-D5-M Optimus GX PRO 850X fit my laptop slot?

The drive measures 8.9mm tall including its integrated heatsink, so it fits standard M.2 2280 slots that allow double-sided modules with a heatsink.

What is the installation step people skip with the PCIe 4.0 x4 NVMe 1.4 drive?

After seating the module and securing the screw, many forget to enable the PCIe 4.0 x4 link in BIOS so the drive runs at NVMe 1.4 speeds instead of falling back to an older generation.

When should I plan to replace the 1TB 3D NAND TLC drive based on its 600TB endurance rating?

The 600TB written endurance and 1,750,000-hour MTBF indicate a long service life; monitor the SMART percentage-used attribute and replace the drive once it approaches 100% or if reallocated sectors begin to rise.
