The SSD controller is the 88SS1074 Dean from Marvell, a DRAM cache chip is available. Kingston has installed TLC NAND flash on the UV400, the flash chips are made by Toshiba.

The UV400 is rated for sequential read speeds of up to 550 MB/s and 490 MB/s write; random IO reaches 90K IOPS for read and 25K for writes.
