I'm trying to find a small, cheap SSD option that is used primary for writing to as a scratch space or a temporary cache that is often emptied and refilled. I guess it only really need to keep up with the reads of a fast hard drive. I know SSDs have limited writes but I don't really need much space (32GB-64GB would get the job done even).
What is giving me a headache is how a lot of smaller SSDs actually have unimpressive write speeds because of their limited channels. Also, the lack of dram means many low end models will suffer slow downs on a sustained write. What I don't want is for the thing to choke out while I'm pushing 20GB to it.
I sort of looked at those optane drives for this but their writes aren't anything special. But they are in the 200MB/s range, actually like half that for 16GB. Is it reasonable to assume that is enough to not bottleneck reads from a fast hard disk?
