Our take on the SanDisk Optimus 5100 SDSP51400TAN-000E0 4 TB Solid State Drive, M.2 2280 Internal, PCI Express NVMe (PCI Express NVMe 4.0 x4)

The SanDisk Optimus 5100 is a PCIe 4.0 NVMe M.2 2280 internal SSD aimed at creators who need lots of fast storage. The 4TB model reads up to 7,300MB/s and writes up to 6,700MB/s, with nCache 4.0 for smoother multitasking and large file copies. It uses 8th-generation BiCS QLC NAND, which keeps capacity high but trails TLC drives on sustained writes and endurance. It suits video editors, photographers and anyone adding a big secondary drive to a desktop or compatible laptop.

Pros
  • High sequential read and write speeds over PCIe 4.0 x4
  • 4TB capacity in a slim single-sided M.2 2280 format
  • nCache 4.0 helps with burst writes and app multitasking
  • Power-efficient design suits laptops
  • Five-year limited warranty and SanDisk Dashboard monitoring
Cons
  • QLC NAND slows on long sustained writes once the cache fills
  • Lower endurance than TLC drives of the same capacity
  • Full speed quoted for 1TB and 2TB models; 4TB reads rated 7,300MB/s
  • Dashboard software is Windows only
  • No heatsink included, so sustained loads may need airflow

What reviewers say

Owner feedback on the Optimus 5100 line is limited and mixed. Buyers like the capacity and everyday speed but note that heavy sustained writes expose the QLC limits.

What people mention
  • Write speedMixedUsers report strong burst speeds but slower sustained writes once the cache is exhausted.
  • CapacityPraisedOwners value getting 4TB in a single slim M.2 2280 drive.
  • EnduranceCriticisedThe QLC NAND gives a lower endurance rating than TLC drives of similar size.
  • HeatMixedThe drive can run warm during long writes, so airflow or a heatsink helps.
  • SetupPraisedBuyers find installation straightforward in compatible laptops and desktops.

About the SanDisk Optimus 5100 SDSP51400TAN-000E0 4 TB Solid State Drive, M.2 2280 Internal, PCI Express NVMe (PCI Express NVMe 4.0 x4)

The SanDisk Optimus 5100 is a 4 TB internal NVMe solid state drive in the slim M.2 2280 form factor. It uses a PCIe 4.0 x4 interface and is made for creators who work with large files such as 4K video and high-resolution images. It can be used to upgrade a compatible laptop or as an added high-capacity drive in a desktop PC.

The drive uses 8th generation SanDisk BiCS 3D CBA NAND and integrated SanDisk nCache 4.0 technology, which supports multitasking and fast file copies. Its power-efficient design delivers high performance at low power consumption. It has an endurance rating of up to 1,200 TBW and a 5-year limited warranty.

The downloadable SanDisk Dashboard application (Windows only) lets you monitor the drive's performance and check for updates. Acronis True Image for SanDisk software is available as a free download to transfer data to the new SSD. A separate cable or enclosure may be required for the transfer.

Questions and answers

Is the SanDisk Optimus 5100 good for video editing?
Yes for storing and scrubbing large 4K files, thanks to high read speeds and 4TB capacity. Long exports that write continuously can slow once the SLC cache fills, so pair it with a TLC scratch drive for heavy sustained work.
How does it compare with TLC drives like the WD Black SN850X?
The Optimus 5100 offers more capacity per dollar but uses QLC NAND, so sustained writes and endurance are lower. TLC drives cost more but hold speed better under long loads.
Does the 4TB model hit the quoted 7,100MB/s?
No. The 7,100MB/s read figure applies to the 1TB and 2TB models. The 4TB model is rated up to 7,300MB/s read and 6,700MB/s write.
Will it fit my laptop?
It fits devices with an M.2 2280 slot that supports PCIe 4.0 or 3.0 NVMe. Check that your slot accepts a single-sided drive and has room for airflow.
Does it come with a heatsink?
No. It is a bare M.2 2280 drive. Desktop boards with built-in heatsinks or aftermarket pads help keep temperatures down under sustained writes.
What is in the box?
The drive itself. No heatsink, screw or cable is included, so check that your motherboard or laptop has the mounting hardware.
Where is the SanDisk Optimus 5100 SDSP51400TAN-000E0 4 TB Solid State Drive, M.2 2280 Internal, PCI Express NVMe (PCI Express NVMe 4.0 x4) cheapest?
