Longsys Foresee XP2350 FSB0C512G-F6C2700

XP2350 FSB0C512G-F6C2700

The FSB0C512G-F6C2700 is a PCIe 4 NVMe drive that seemingly launched in Q2 2025. This is a 512-GB, M.2 22 by 80 model but there are 1-TB, 2-TB, 4-TB and 8-TB as well as 80-mm, 42-mm and 30-mm variants on offer, too.

Performance

While there is no official product page, retailers list the 512-GB model's peak sequential read and write rates as 6.1 GB/s and 2.0 GB/s, respectively.

In our tests with AS SSD and DiskSpd, the latter is confirmed, but reads are much slower at 2.4 GB/s (DiskSpd) to 3.8 GB/s (AS SSD), which puts the XP2350 closer to good PCIe 3 SSDs than good PCIe 4 ones.
