Beware... do NOT buy this Bullshit!
At least the 256GB is utter trash das does NOWHERE near 900mb/s write... more like 45-90mb/s
First i tried to copy a Game Folder...
After the Cache is full it drops to utterly slow speds.
So let's check that via Terry Copy how Long/Slow exactly...
86mb/Sec
Okay... maybe many small files are not a fair comparison? let's check 4gb chunks...
That looks better but is not really any faster... 97mb/s
Just for confirmation... i use an internal 2TB Adata SX8200Pro nvme Drive... no limit there! Read and Writespeed 456mb/s
So something is clearly broken right? let's Benchmark that!
Atto at 32mb File Size does fairly well.. 850-900mb/s write speed.. so my USB Port is not limiting, nor any other Problem with my Computer.
P.S yeah. i used the Port which had the 10GB/s written beside it...
Port Nr 7.
increasing FileSize to 32gb we can see the speed dropping to 550mb/s but still... that woulkd be kinda OK....
so what does AS SSD Benchmark say?
Yeah... thats more like RealLife experience.... 111mb/s
HD Tune says the same...
Writespeed of 84mb/sec
So yeah.... i wrote to the seller and he was "oh, we checked with the manufacturer, seems like you got a broken unit, here is your money back".
Like how? Did a few NAND get squashed while transport or what?
No... IMHO either the controller can't fully show his potential with only 256gb nand because there are not enough channels connected, or they changed NAND after the first few Reviews and now it's utter trash.
So i bought the 512gb version which was on sale for 41.- to check if it has the same issue... brb few hours, edit inc.
P.S just in case anyone thinks the stick overheats.... no, after each test i put the stick in the Freezer for 5 minutes and let it acclimate for 10 minutes with room temperature.
So IF the stick overheats then that happens during the benchmark session itself. which makes the stick kinda Useless.
Room temperature is a few degres over optimum 21°C but that shouldn't really affect testing at all.
P.P.S
Does anyone now of Software to read Nandchips that works with USB sticks and the
Silicon Motion SM2320 SSD controller.
isn't that all nvme based?
