It all goes around... You may recall that IDE disks, Integrated Drive Electronics, were hard disks with most of the controller placed on a board on the drive itself, reducing the IDE interface to, approximately, a set of buffered and multiplexed connections to the ISA bus. Eventually this became a carrier for SCSI and SCSI-like protocol commands. High performance SSDs are now being made so that they connect directly to the PCIe bus, usually through a miniPCIe connector, sometimes through a variant. If the circumstances of manufacture are such that space and weight restrictions are more important than repairability, the producer may place an SSD directly on the motherboard. It is more usual, however, to have the M.2, NVMe or other PCIe-like connector available, since they are quite small. -dsr- _______________________________________________ Discuss mailing list [email protected] http://lists.blu.org/mailman/listinfo/discuss
