The Pilot-E is an internal NVMe SSD available in 250 GB - 2 TB capacities, with an astonishing up to 3.4 GB/s read and 2.5 GB/s write speeds, powered by an SMI SM226EN controller and 3D TLC NAND. Another lower-tier interpretation of the Pilot-E is the Pilot, which ranges from 120 GB - 2 TB, but uses a slower Silicon Motion SM2262 controller which brings the performance numbers down to 3.2 GB/s and 1.9 GB/s in sequential read and write. The Carbon X100 external SSD is available in both chrome and black, and leverages a USB 3.1Gen 2 connection to make your storage as fast and as portable as possible: Mushkin quotes 1000 MB/s read and write operations across the 250 GB - 1 TB offerings. Prices and availability were not announced.
