Drive:This drive uses a hybrid pSLC Cache design, which can spans to almost a third of the drive's capacity. The nCache 4.0 is a really awesome design that has 6GB(*) as a Static pSLC Cache with almost 150 GB(*) reserved as dynamic which shrinks as the drives fills up. NAND Die:Read latency tR: 58 µs (ABL) |
