I wanted to replace my old 128GB AData M.2 SATA system drive. The drive is plenty big enough but Passmark identified it as a huge bottleneck in my system (it is SATA after all).

So, I found a 250GB WDB SN770 for $40CAD at Memory Express. I went into the store and the guy said that he had an even better deal for me.

I managed to prevent my eyes from glazing over and, just to be polite, I allowed him to talk me up to a 500GB version (that was, for some reason, a faster drive) for just $5CAD more.

They’re pretty good guys over there, eh? 😉

If you have an older computer that doesn’t have any SSD, this will make it fly. I did a 5-minute install on my Dell G5000 Desktop and all the hard work was taken off of me because everything just fell into place! It’s so easy with how straightforward these parts are – installation could not be easier either; there were no problems at all after following some quick YouTube videos I found online (link). And best yet? Price wise M2 from reliable manufacturers can give your tired machine new life by boosting performance like never before while still saving money in comparison to buying another one outright which saves cash over time too.

Thanks for the test.

So is the controller new? The one used in the WD850?
Finally the BiCS5 nand! Can you disclose when you do the test of the upcoming WD850X?
Will it be faster or slower? I guess the X means faster 😉

Temperatures are nice indeed.
Game loading shows that there is a flaw in performance. Due to the firmware? Maybe it can get better.
The PCMark comparison is good, but as said on the test Cardea 440 Pro, your tests would benefit greatly with more real world testing instead of synthetic benchmarks.

For this DRAM-cacheless ssd, I totally not know after what amount of GB the ssd starts to stumble and switch the pseudoCache from slc to mlc to tlc. That would be one of the important metrics to test for a dram-cacheless ssd I’d say, even when the target audience is a one that do not rank writing the whole disk in one sweep.
What is the simultaneously mixed writing/reading-performance is,
