Question SSD got slower writes all of the sudden

[naruto66]

Hello, i got a Samsung 860 250gb SSD for 2 weeks now, at first it worked fast then i started installing more things like Steam, Uplay etc..
then the write speed dropped down to 300Mb/s instead of 500Mb/s and now it's kinda slow like it takes more time to open things now than it did before,

i downloaded Samsung magician software and checked everything was fine
"firmware latest update, AHCI enabled, TRIM is enabled"

i tested it on a benchmark and surprisingly everything looked fine the speeds were at full but in live windows it's not why is that ?

The drive would likely need 40+ GB of free space to maintain peak speeds, but then, read/writes will never be at a constant 500+ MB/sec, as those are merely the advertised specs, which you should see on sequential reads/writes pretty much just on Crystal Disk Mark, etc... Random reads/write speeds for smaller files will always be less...

(If CrystalDiskMark still shows 500 MB/ on sequential reads/writes, and you have enough free space, you are probably good)

i do have more than 40GB of free space, thing is i did try CrystalDiskMark it's 500 MB/ but it's still running slower than before it takes more time to open things.

300 mb/s? I have about 10 on a 1tb 860 evo
