Abnormally fast Sata SSD benchmark speeds

You have some sort of caching enabled. A SATA SSD cannot achieve speeds anywhere near that high. I can't remember what Samsung calls it, but I do know that their software offers caching, so if you turn that off you'll see the proper performance numbers.

Was recently benchmarking some drives and realized my one 870 EVO SATA drive had abnormally high benchmark speeds.

Transfer speeds are perfectly normal around 500 MB/s 

 

I guess I was really just curious as to what caused this and since google wasn't providing much of an answer, I figured some of you guys on here might have had something similar happen!

Rough guess, RAM cache, not DRAM on the drive, but system RAM. Look for an option in the Samsung software to turn it on/ off, benchmark again.

Makes sense! I mainly just downloaded the Samsung magician cause i thought crystaldiskmark was bugged. 

I'll snoop around in there and see if I can find it, thanks!

Was gonna say, this thing must have a monster cache.

Due to the above, I've likely revised posts <30 min old, and do not think as you do.
