Capacity and form factor

This Yoetaun PM991A drive provides 1TB of storage in the M.2 2230 form factor measuring 22mm by 30mm. It uses a PCIe 3.0 x4 NVMe interface and single-sided TLC flash with a 1GB cache. The compact size targets laptops, ultrabooks and tablets that only accept 2230-length modules.

Sustained throughput

Sequential reads reach 2400MB/s and writes reach 1950MB/s over the PCIe 3.0 x4 link. The 1GB cache absorbs write bursts before flushing to the TLC array. Full Power Mode keeps the controller at its peak clock during extended transfers rather than throttling after a short burst.

Compatibility checklist

Verify that your device has an M.2 slot keyed for PCIe NVMe and that it physically accepts a 2230-length module. Confirm the BIOS or UEFI supports booting from an NVMe drive on PCIe 3.0. Ensure the single-sided PCB clears any motherboard components or thermal pads in the target slot.

Questions about this item

How much power does the PM991A draw under full PCIe 3.0 load?

The PM991A uses a PCIe 3.0 x4 interface with TLC particles and a 1G cache, rated at 2400MB/s read and 1950MB/s write speeds for efficient operation.

Does my laptop need an M.2 2230 slot and NVMe support to install this drive?

Yes, the PM991A requires an M.2 2230 slot measuring 22mm by 30mm and a system that supports NVMe over PCIe 3.0 for proper installation and boot.

Will the PM991A work in an older ultrabook limited to PCIe 3.0 speeds?

The PM991A operates natively on PCIe 3.0 x4, delivering 2400MB/s reads and 1950MB/s writes, so it matches the older ultrabook interface without bottleneck.
