Overview
Not a SATA drive, the SN7100 is a slim PCIe NVMe module built with TLC 3D NAND for gaming laptops and handheld consoles. It slots into a matching module bay and is described as power efficient at top speed.
Quick reads cut load times, and a thin, light module suits tight laptop and handheld bays. The built-in media field lists only the SSD itself, so there is no heatsink or software offer in the listing.
Who it's for
A gamer replacing or expanding storage in a laptop or handheld console. The line reaches larger capacities if one terabyte is not enough. Buyers who want accessory software or a pre-fitted heatsink should look at other kits.
Pros and cons
- Fast Gen4 read and write
- Thin and light module
- Power efficiency at top speed
- Capacity options up to four terabytes
- No heatsink listed
- No software listed
- Enclosure material not listed
- Sequential speeds are best-case figures
Performance notes
The listed speeds apply to large sequential transfers on a Gen4 x4 slot, while everyday loading depends on random reads. TLC 3D NAND stores more bits per cell, which trades some sustained write speed for capacity. Heat builds under long writes without airflow, so thermal design in the host affects results.
