SanDisk Optimus 5100 500GB PCIe 4.0 x4 NVMe SSD

The SanDisk Optimus 5100 is a 500GB internal solid state drive using QLC 3D CBA NAND. It connects via an M.2 2280 form factor with a PCI-Express 4.0 x4 interface and NVMe protocol. Sequential reads reach up to 6600 MBps and writes up to 5600 MBps. Random read performance hits 660,000 IOPS while random write reaches 1,100,000 IOPS.

Check motherboard M.2 slot key

Verify the board provides an M.2 2280 slot wired for PCI-Express 4.0 x4 and NVMe signalling. Confirm the slot accepts single-sided modules 2.38mm high and 22mm wide. Ensure the system BIOS supports NVMe boot if the drive will hold the operating system. No heatsink is included so assess airflow around the slot.

Thermals noise and power in normal use

The drive operates between 0°C and 85°C with no moving parts for silent running. Idle power draw is 4 mW while active read and write average 3.8W each. Endurance is rated at 300TB written and MTBF at 1,750,000 hours. Shock resistance reaches 1,500G at 0.5 ms and vibration tolerance covers 5 gRMS operating.

Questions about this item

Will this M.2 2280 drive fit in a laptop slot that is only 22 mm wide and 80 mm long?

Yes, the drive measures 22 mm wide by 80 mm long and 2.38 mm high, matching the standard M.2 2280 slot dimensions.

Does the 500 GB capacity and 300 TBW rating suit a daily driver with heavy write workloads?

The drive offers 500 GB usable space and is rated for 300 TB of total data written, which supports several hundred gigabytes of writes per day over a typical five-year lifespan.

My motherboard has a PCIe 4.0 x4 M.2 slot — will I see the advertised 6600 MB/s read and 5600 MB/s write speeds?

When installed in a PCIe 4.0 x4 slot with NVMe support, the drive can reach up to 6600 MB/s sequential read and 5600 MB/s sequential write, provided the system cooling keeps the controller within its 0 °C to 85 °C operating range.
