Why test this SSD on an out of date bios and old Agesa code?
Apart from that, pretty good review
My SN850 is DOA, RMA in progress due to low write speeds:
WD SN850 Slower than expected performance | TechPowerUp Forums
Or these drives are bugged on newer agesa code and chipset, that's my conspiracy theory
First of all, you're clearly not a reviewer, nor even capable of providing necessary information when asking questions, so in your thread, we have to ask you questions to try to solve your problem. Benchmarking systems stay the same, for a very long time, or you end up having to start over from scratch, as all parameters are no longer the same and this means you have to re-test everything if you don't want to start from a clean sheet.
Secondly, DOA doesn't mean what you think. It means Dead on Arrival, i.e. it never worked. Your drive clearly worked, you just found one of the odd glitches that happens with SSDs at times. I also informed you I had a similar problem, but I can't remember exactly what solved it, as it was a couple of years ago. It's not a faulty drive.
And you're drawing conclusions based on your one drive experience, which makes it a flawed conclusion.
You clearly don't know much about hardware when you admit you don't even know how to format a drive with different sector sizes. If you're going to bash
@W1zzard for how he reviews things, then you better be at his level or better at what he's doing.
