In reply to dravo1.

The supercap adds a few $s to the BOM, depending on the size of the cache, and whether the device/controller operates in cache protection mode (which keeps some flash memory erased and ready to accept the contents of the cache).

As for their use of DRAM cache to speed up performance, that’s why CoreRise has used the supercap: You get all the write speed benefits of a large DRAM cache, with no loss of data integrity. The supercap acts as an internal UPS to ensure that there’s time to write all the cache contents to flash after a power loss/interruption.

I’ve always wondered just how much a supercap adds to the price of an SSD. I suspect very little. These should have been standard on all models, not just the enterprise ones. Just a marketing gimmick to boost prices.
As for access time performance you have to be cautious here. A controller designer can use DRAM as a crutch to boost performance and there is always a tradeoff. In this case it’s an incrfeased risk of data corruption or loss. The large DRAM cache becomes a data integrity risk as well as performance enhancer. Hell, if you used enough DRAM you could achieve RAMDISK performance across the board.

tbh i was hoping this new pro version SSD would do extremely well, was really looking foward to a sandforce drive out perform the plextor m3pro. currently sandforce drives been doing pretty well with the incompressible data at over 300mb/s but thats just crystaldisk though, which shows the best possible results unlike AS SSD which shows the worst possible result.

quite frankly the lowest results showing in AS SSD for plextorm3p are way too good, and its access time simply amazing lol. sandforced write latency usually around .18-.2 ms, just cant beat marvel/samsung controller.

i’ll probably just wait till something* that has really good 4k speed, something a bit better than the intel 520 drives
