MicroSD cards are tiny but slow; the M.2 storage sticks in your PC are blazing fast but bigger and fully enclosed. Now, a new type of SSD out of China could be the best of both worlds — and it’s already set to appear in two cutting-edge gaming portables. And while a full-size SD Express card could theoretically beat Mini SSD at 3,940MB/s, it would be nearly twice the size of Biwin’s creation. OneNetbook’s upcoming OneXPlayer Super X hybrid laptop/tablet, which has the same Strix Halo chip, is also now advertising a dedicated “card slot” for a mini SSD. We don’t have any idea of pricing on these new SSDs, and have seen no product listings for them yet.
