yea something weird everytime i turn the pc on now i got a message from magician about WMI not activated.

i should investigate a bit with bios settings coz this ssd replace an old nwme ssd card and i had to do some changes in the bios back in the days, so maybe i should change something to get better results, but for now my 850 pro is running a bit too slow

My 950 pro was running slow also. Looked in device manager and for my AHCI driver the standard Microsoft driver was listed,( my ssd was listed as a removable device in "safely remove hardware"). I found an Intel driver that was modded for W10 and also digitally signed. Upon installation ssd was removed from "safely remove hardware" and my read write scores increased greatly.

Yes and I hate how Microsoft  tries to force people to use their generic drivers.

Most people don't know the difference

yea,

actually my ssd was not on ahci mode, so i changed that and put it on the marvel sata 6. (the intel drivers are not working for these ports)

But was even slower lol

guess i will switch it back to a sata 2 (but with intel drivers) and see if it makes a difference.

 

problem is that this system is getting old (1156 slot) and that fkn marvel port is shit. in other words im stuck with sata 2 speed anyway.

 

gona build a new system soon, but i wanna keep this one as clean and fast as possible

WMI is a service on windows. Go to admin tools, open services and look for Windows Management Instrumentation near the bottom and see if it is started. If not, see if its set to automatic or manual. Also, install and run Samsung Rapid app.

Keep in mind that most munufacturers ssd's will not update the firmware unless it's in AHCI mode.

checked and it is set on automatic start.

i guess if i set it on manual, it wont start unless i start it myself, then something else cause it not to start or maybe it start after magician check if its on ? i dunno

 

anyway, after installing and rebooting about 20 times, magician see my ssd on SATA 6 with AHCI activated and TRIM  enabled, so that is a +.

but speed is too low still

no, its on the marvel drivers (the only 6GBs sata slots on my board) i did install the intel drivers for the 3GBs sata slots.

actually i had better sequential write speed with the windows drivers but the iops was way slower.

 

i still have to try to plug it in the 3GBs sata and see if it makes a difference.

gona try later this evening if i have time

Marvel SUCKS ASS

Seriously my old Intel 775 ddr2 mobo had Marvel raid and I tried running 2 240gb Intel 520 series SSDs in raid 0 in a PC but it was slower than FUCK.2x faster on the regular old sata 2.My brother had the same problem on a 1156 i7 board.

 

I had a slight problem on my current PC with SSD write speed being 1/2 the advertised speed.Turned out that after doing alot of research on the subject my partition was misaligned.There is a couple tools out there to realign it but haven't found one for free.I ended up going to piratebay and found a good one.I installed it and ran it and uninstalled it.Tested again and it was good to go.

 

Most SSD manufacturers use ATTO disk management benchmark utility because it doesn't use Compressed data to test with.You get a much more accurate reading with uncompressed data but in the real world everything you use has compressed data.So speeds will definitely be a bit slower than advertised.

 

I can hook you up with ATTO and an alignment tool if you want.

 

 

Here my Intel 520 240gb.Advertised  520/550 @ up to 8gb length 512k-8mb transfer size.Real world test with ATTO 497/545. They say tests results may vary up to 20% depending on how much crap you have on it. Manufacturers also test with Empty drives.

 

ATTO disk benchmark Here.

https://www.techpowerup.com/download/atto-disk-benchmark/

 

Alignment tool is Paragon Professional Alignment Tool 4.0 PM me if you want it and I'll upload to a file host and send ya the link.

That's exactly what i have a 1156  board with an old i7 870

i never did change it because it has a firewire and i need this.

But anyway did'nt had time to put the disc on the sata 2 yet.

 

i dont wanna risk loosing my files, i'll just try this and if speed doesn't change, fuck it, i'll stay like this.

 

and build a new system with a 7700K or with RYZEN we'll see
