Overview
- The Mini SSD (1517) measures just 15×17×1.4 mm and offers 512 GB, 1 TB and 2 TB capacities with claimed sequential reads up to 3.7 GB/s and writes up to 3.4 GB/s over PCIe 4.0 x2.
- Its performance is more than three times faster than microSD Express and approaches full-size SD Express bandwidth in a footprint under half the size.
- Biwin highlights an IP68 water and dust resistance rating plus three-meter drop protection housed in a SIM-style tray for easy insertion and removal.
- Two Chinese gaming handhelds—the GPD Win 5 and OneXPlayer Super X—are the first devices announced with dedicated Mini SSD slots at ChinaJoy.
- The format currently lacks JEDEC standardization, requires proprietary host support and has no announced pricing or retail availability, leaving broader adoption uncertain.
