SSD Dram

Go to solution Solved by Chris Pratt,

It doesn't look like it based on the board. I see the controller and a single NAND chip (normal for small capacity drives like this) but nothing else. Based on how much they talk up SLC cache on the product page, seems a safe bet that they're relying exclusively on that, rather than DRAM.

 

SLC cache isn't necessarily bad, and you can still attain pretty good read and write speeds, but it's usually like only 8GB or so. That means it'll perform fine for short, bursty writes, but once you saturate the cache, speeds are going to fall off a cliff. Long, sustained workloads are going to be painful.

 

As an OS drive, that could be a mixed bag. For day to day operation it will probably perform fine, but I would expect the initial Windows install and any subsequent updates to take half a century.

so i just buy this cheap ssd just for my OS and i wanna kn ow does my ssd have Dram or not? and if it have one which one is it i dont know
