DRAM could provide a buffer between the computer memory and the drives blocks that are actually written to (TLC) , the controller has a little but 32MB is full really fast.
Problem for me having the same use case for this drive as Orang3Beard is that in a NAS this could be a great replacement for spinning disks, but in RAID it would be just too limited. The real bottleneck is here :
Die Read Speed: 727 MB/s
Die Write Speed: 69 MB/s
With a die write speed of less then 100MB/s this thing could be in continued write much slower then a comparable HDD. Painfully slow to fill up, probably quite decent to retrieve information from.
Found a review that shows with a screenshot what this could look like:

Cons:
Reliability seems to be an issue according to some reviews.
Pro's:
Endurance: 450 TBW
Warranty: 3 Years
MTBF: 2.0 Million Hours
For me I would not want to make a ZFS RAIDz2 volume with these. Maybe a normal RAID1 would be cheap peace of mind..
Unless you are refurbishing an old computer for a family member that does not have to work hard daily I believe almost everybody would be helped spending $10-15 more for something better.
At this rate no reason to have spinners anywhere in the house, save for the NAS.
Yeah it's not a performance beast but it's good enough for most users. Time to upgrade Granny's laptop

I ran some benchmarks on the 240GB drive using fio under Linux. First test was writing 50% (120GB) of the capacity. It sustained ~325 MB/s for the first ~80GBs then dropped down to around 45 MB/s thereafter. If I stop the I/O and restart after a while it resumes back to 325 MB/s. Not a big deal unless your filling up the drive all at once. Sequential reads sustain around 373 MB/s. 4K QD-4 random writes sustain ~12K IOPs but have intermittent drops to very low values for around a second - probably internal remapping. Overall impression is pretty good for the price paid.
This is a good price, but around 40 is average now. I had this same one on my list for the past couple weeks at 40.99.
