DATA Technology today launched the ADATA IUSP33F PCIe ball grid array (BGA) solid state drive (SSD). An ideal solution for slim-form-factor tablets, notebooks, hybrids, mini-PCs, thin clients, and wearables. Up to 1195MB/s read and 940MB/s write. Not blistering speeds but more than fast enough for the devices for which it is marketed. Engineers are always trying to make devices smaller so this type on device should help in that regard.
