● Ultra-small BGA form factor – 80% more compact than M.2 2242 SSDs
● Fast PCIe Gen3x2 interface : R/W speed up to 1195/940MB per second
● NVMe 1.3 support
● 3D NAND flash for improved capacity, durability, and power efficiency
● Host Memory Buffer (HMB) for performance boost and low power consumption
● LDPC and SRAM ECC Technologies
● End-to-End Data Protection
● Suitable for compact devices, such as ultrabooks, tablets, VR, Mini PC, thin clients, wearables, smart driving and robots


As the first PCIe BGA SSD of ADATA, IUSP33F sports a form factor that is 80 percent more compact than M.2 2242 SSDs. Combined with a PCIe Gen3x2 interface and 3D Flash memory for excellent performance and durability, the IUSP33F is an ideal solution for slim-form-factor tablets, notebooks, hybrids, mini-PCs, thin clients, and wearables. It also supports Host Memory Buffer to maintain high performance without integrated DRAM by using host memory for flash management purposes, while at the same time reducing power consumption. In addition, the IUSP33F supports LDPC and SRAM error correcting code technology to detect and fix a wider range of data errors for more reliable data transfers and a longer product lifespan. What’s more, E2E Data Protection defends it from damage or inconsistent data to minimize downtime and reduce maintenance costs.
