Capacity and interface

The Crucial E100 is a 1TB internal solid-state drive built in the M.2 2280 form factor. It connects through a PCI-Express 4.0 x4 interface using the NVMe protocol. The drive operates without a dedicated DRAM cache, relying on host memory buffer technology instead. Sequential speeds reach up to 5000 MBps read and 4500 MBps write.

Who this suits and who should look elsewhere

This drive suits builders upgrading a laptop or desktop that has an M.2 slot wired for PCIe 4.0 x4 and who want a lightweight 6.00g module without a heatsink. Systems limited to PCIe 3.0 will not reach the quoted speeds, and chassis that require a heatsink for thermal compliance will need a different model.

Bundled accessories and software

The package contains only the bare drive; no mounting screw, heatsink, cloning utility or software licence is included. Buyers must source a motherboard standoff screw separately and rely on the operating system for drive management and firmware updates.

Questions about this item

Does my motherboard need an M.2 2280 slot with PCIe 4.0 x4 support to use this drive?

Yes, the CT1000E100SSD8 requires an M.2 2280 slot wired for PCIe 4.0 x4 and NVMe protocol to operate at its rated 5000 MBps read and 4500 MBps write speeds.

Will this PCIe 4.0 x4 NVMe SSD work in my older motherboard that only has PCIe 3.0 M.2 slots?

The drive is backward compatible and will function in a PCIe 3.0 x4 M.2 slot, but sequential read and write speeds will be limited to the PCIe 3.0 bandwidth ceiling.

How can I verify the E100 is delivering its rated 5000 MBps read and 4500 MBps write performance after installation?

Run a sequential benchmark such as CrystalDiskMark using a 1 GB test file on the NVMe drive; results approaching 5000 MBps read and 4500 MBps write confirm expected operation.
