hey guys i brought a sandisk extrme ssd which has a sata3 connector so i upgraded my motherboard so it wood support it and let me use the full read and wright speed which is meant to be 510 read and 510 wright, ive done a cryatal disk scan and it says on there that the disk reads

READ WRIGHT
SEQ 266.8 131.7
512K 268.0 121.8
4K 21.60 74.40
4K 22.60 103.7
QD32

is this right or is it wrong i have it all plugged in right my motherboard supports sata3 6gbs.

any help pls

CrystalDiskMark uses highly incompressible data to test Read/Write speeds.

Benchmark with ATTO software and see if you get the advertised Read/Write speeds.
ATTO uses highly compressible data to test Read/Write speeds.

ok ive just done that and it says max read was 329 and write was 378 this is bit better but shouldnt it be running at the full speed have i missed a bios update even tho i cant find one anywhere or anything else? should it be a simple plug and play ssd? never had one before... cheers for help

How many CDM tests did you run?

 

[stew198269]

0.5/8192 think that ehat u mean

 

[Dereck47]

No, how many times did you run CrystalDiskMark benchmark test?
Each test run Writes 20GB of test data at the default settings.
If you've run more than 3 tests in a row that could be the reason why your Read/Write speeds are low when you ran ATTO.

 

[stew198269]

only did it the once but just tryed it again and it showing up to 300 read and write has dropped to 131

Log off (not Shut down) before you go to sleep tonight. This will allow Garbage Collection to run and recover drive performance.

ok and then try cdm or atto

ATTO

Also, you didn't state whether or not the SATA port your drive is connected to is in AHCI mode. All SSDs need to be connected in AHCI mode for best performance.

 

[stew198269]

no its not running in that mode can i change this at any time even tho i have windows installed

 

[Dereck47]

You need to edit the Windows Registry file first. Then boot into BIOS and change the SATA mode from IDE to AHCI.
