Torture tests elsewhere also reveal such NAND to be easily capable of surviving huge workloads, while the latest figures from Samsung suggest the original 840 EVO drives can survive at least 2,500 program/erase cycles. Though many have previously raised concerns about the endurance and performance of such NAND, the latter appears to be mostly unfounded. Samsung is sticking with 3-bit MLC (TLC) NAND for the EVO mSATA range, produced on a 19nm process. The 1TB drive features four separate NAND packages (2 on each side of the PCB), each with a whopping 256GB crammed inside. Also, unlike the 2.5-inch drives, there will be no upgrade bundles with mSATA to USB or mSATA to SATA adaptors supplied - a somewhat surprising choice, particularly for laptop upgrades. As well as the 1TB model, the 120GB, 250GB and 500GB ones will also have mSATA equivalents, but not the 750GB one. Of course, mechanical drives are still far cheaper, but equally they're much larger and slower. We've listed £509.99 as the MSRP, since this is in line with that of the original drive, but with 1TB SSD 840 EVO models selling for around £460 it could well be less by the time it hits retailers' shelves. The better news is that the mSATA version of the EVO has the same recommended price as the regular one, so there's no premium for the smaller size.
