The IO Crest full height MiniPCIE to SATA III 2 ports card (SI-MPE40160 ) is the easiest way to update any computer with SATA ports with a free M.2 A+E Key 2230 mm slot. Once installed, this host card will add SATA ports with two independent channels. This allows support of two SATA devices at speeds of up to 6Gb/s whether it is a SATA hard drive or SATA device. Using the JMB582 chipset, theSI-MPE40160 can provide a maxium sequencial Read / Write Speed of 850 MB/s to 2 SATA 6Gb/s ports. For the storage solution based on data transfer of multiple hard drives, the newly added FIS-based switching design can overcome the bottlenecks created by operating multiple SATA storage devices simultaneously.
