KingFast has announced a new SSD with a 1 TB capacity, accomplished by putting two 512 GB SSDs in a RAID 0 array.
  KingFast, a Chinese manufacturer, has announced its new 1 TB SSD, ingeniously named the "C-Drive." The drive itself might look like any other 2.5-inch 9.5 mm SSD, but underneath the housing you'll actually find two SSDs. The device contains two 512 GB SSDs, each driven by its own SandForce SD-2281 controller. The two work together to create an internal RAID 0 configuration. While there is no official word on TRIM support, due to the RAID 0 configuration, it is likely that the drive does not support TRIM commands.
  The drive has a SATA3 interface, can reach sequential read speeds of 559 MB/s and write speeds of up to 532 MB/s. There was no word on the device's pricing or availability.
