Closer Look at the Patriot Viper VPR100
There are two SK Hynix H5AN4G8NBJR 4GB DDR4 DRAM cache chips (one on each side of the module).
There are four NAND 256GB chips which bring total capacity to 1TB. I couldn’t find more information on these chips.
Phison E12 Series Controller (PS5012-E12) is the heart of VPR100 and is responsible for its transfer speeds. This controller supports capacities from 256Gb to 2TB with approximate 3000MB/s Read/Write Sequential speeds. 4K Random Read/Write has 600K IOPS.
To accelerate flash operation VPR100 has a Holtek 32 bit ARM processor F52231.
