SanDisk Optimus 5100 2TB M.2 2280

The SanDisk Optimus 5100 is a 2TB internal solid state drive built on the M.2 2280 form factor. It uses a PCI-Express 4.0 x4 interface with the NVMe protocol. The drive employs QLC 3D CBA NAND memory components. It is designed for desktop and laptop users who need high-capacity storage for operating systems, applications and large media libraries.

Sustained write behaviour on QLC 3D CBA NAND

The drive delivers a maximum sequential write speed of up to 6700 MBps and a 4KB random write rating of up to 1,300,000 IOPS. Under heavy continuous workloads the QLC architecture writes directly to the flash after any SLC cache is filled. The 900TB terabytes written rating and 1,750,000 hours MTBF indicate the endurance ceiling for long-term write-heavy usage scenarios.

Thermals noise and power draw in normal use

The drive operates without a heatsink and has an idle power draw of 4 mW. Average active power consumption is 4.1W for both read and write operations. The operating temperature range spans 0°C to 85°C. With no moving parts the drive produces no acoustic noise during operation.

Questions about this item

How much power does the Optimus 5100 draw during sustained all-day workloads?

Average active power is 4.1W for both read and write operations, while idle power drops to 4 mW.

Does my motherboard need a PCIe 4.0 x4 M.2 slot to run the Optimus 5100?

The drive uses a PCI-Express 4.0 x4 interface with NVMe protocol and requires an M.2 2280 key-M slot.

Will the Optimus 5100 fit and work in a laptop that only has a PCIe 3.0 M.2 slot?

It fits the standard M.2 2280 form factor at 2.38 mm height and will operate at PCIe 3.0 speeds in a 3.0 slot.
