DLX4 1 TB M.2 2242 NVMe drive

The VisionTek DLX4 901562 is a 1 TB internal solid-state drive built in the M.2 2242 form factor. It connects through a PCI-Express 4.0 x4 interface using the NVMe 1.4 protocol. The drive targets desktop PC users who need a compact, high-speed storage upgrade for compatible M.2 slots.

DRAM-less design with SLC cache

This model operates without a DRAM buffer and instead relies on an SLC caching scheme to sustain write performance. The approach helps the drive reach sequential write speeds of up to 4370 MBps while keeping the component count low for the small 2242 footprint. Hardware-based 256-bit AES encryption is also integrated to protect stored data.

PCIe 4.0 x4 lane and thermal limits

The SSD requires a motherboard slot wired for PCI-Express 4.0 x4 to deliver its rated 5200 MBps read and 4370 MBps write throughput. If the slot negotiates at a lower generation or fewer lanes, maximum transfer rates will drop proportionally. Sustained heavy workloads may also be constrained by the limited surface area of the 2242 PCB for heat dissipation.

Questions about this item

How long before the 500 TBW endurance rating on this 1TB drive is reached?

The 500 TBW rating means you can write 500 terabytes total before the warranty endurance limit; typical desktop workloads write far less per year, so the drive lasts many years.

What limits sustained write speeds after the SLC cache fills?

Once the dynamic SLC cache is exhausted, write throughput drops to the native NAND speed, which is lower than the 4370 MB/s peak.

How hot does the M.2 2242 module get during all-day PCIe 4.0 x4 workloads?

The compact 2242 form factor concentrates heat; under continuous NVMe 1.4 loads the controller can reach temperatures that trigger thermal throttling unless the motherboard provides a heatsink.
