Chinese flash memory specialist KingFast announced its take on high-capacity compound SSDs with the C-Drive 1 TB. The drive looks like any other 2.5-inch, 9.5 mm-thick SSD, but encloses two subunits striped in an internal RAID 0 configuration, that's abstract to the host, to which it connects over SATA 6 Gb/s. Each of the two 512 GB subunits is driven by an LSI-SandForce SF-2281 controller. KingFast didn't mention if the RAID controller lets the contraption retain support for the TRIM command, but unless they have something substantial like OCZ VCA, we suspect it doesn't. The SATA 6 Gb/s interface clearly bottlenecks the C-Drive, which offers sequential speeds of 559 MB/s reads with 532 MB/s writes, with 5~10% of the interface bandwidth being consumed by the various overheads.It's still the fastest sequential speeds advertised for a SATA 6 Gb/s drive.
