i was wondering why today's gpu have such a large frame buffer ( 1 GB) when they only have to store a single frame at a time like a 1920 * 1080p which comes out to be a frame size of 5.93MB ( 1920 * 1080 * 24 bits).
those Intel drives and sand force are the only ones that don't use a write cache but anything bigger the 128MB is used as a cache because the page map tables (primary use of the dram) do not take up much space.
also its the amount of LUNs per channel that increase write speed
see here...
almost all SSDs use some sort of write Cache because Nand flash writes much slower then it reads
the write speed of Nand flash is 1/4 its read speed per chip
first off the third gen sand-force controller is differently not going to be releases this year
referring back to dram caching i would like to point out that sizes does not always matter if you look at the ocz octain it has a 512MB cache but the Samsung 830 has a 256MB cache. despite the...
i was wondering why ssd's use a singe page size in the whole drive?(25nm nand 8k)
there are benefits to both large and small page sizes so why not have like 2 chips worth of 4k page 34nm nand and the rest of the chips be 25nm 8k page size?
