OEM Grade Flash Storage Products

Our OEM Grade offering provides >6 times Commercial Grade endurance for slight premium in price. Our OEM Grade Flash Storage Devices are built with pseudo SLC NAND memory, which operates MLC NAND in a 1-bit per cell mode versus its normal 2-bit per cell configuration. OEM Grade products have locked-BOM for as long as achievable.

An Overview of Pseudo-SLC NAND

Pseudo-SLC NAND uses MLC NAND in a single bit per cell mode, thereby giving it >6 times the endurance of the same MLC NAND cell used in its traditional two bit per cell operation. Cactus OEM Grade uses this pSLC and is an upgrade from our Commercial Grade which uses MLC NAND.
