Crucial M4 Slower with PCIe Sata 3 card than with normal Sata 2 motherboard connection

post #1 of 4
Thread Starter 
So I have this setup:
Operating System: Windows 7 Ultimate 64-bit (6.1, Build 7600)
System Manufacturer: XFX79U
System Model: XFX nForce 790i Ultra 3-Way SLI
BIOS: Phoenix - AwardBIOS v6.00PG
Processor: Intel(R) Core(TM)2 Quad CPU Q6600 @ 2.40GHz (4 CPUs), ~3.0GHz
Memory: 4096MB RAM
Available OS Memory: 4094MB RAM
DirectX Version: DirectX 11
Card name: NVIDIA GeForce GTX 480
Manufacturer: NVIDIA
Chip type: GeForce GTX 480
DAC type: Integrated RAMDAC
Display Memory: 3294 MB
Dedicated Memory: 1503 MB
Shared Memory: 1791 MB
Current Mode: 1920 x 1080 (32 bit) (60Hz)
Crucial SSD Model: M4-CT128 M4SSD2 SCSI Disk Device


I recently bought the cruical M4 to use for loading these huge BF3 maps... it does great hooked up to the mobo which is sata 2 (3gbs) -- the 790i missed the new stuff.

So I tested this with "dskspeed" and got a max read of 245 megabytes a second...

I thought- perhaps i could get one of these PCIe sata 3 adapters and get something closer to 450- maybe more... considering its going to max the PCI-e connection

I bought this: http://www.newegg.com/Product/Product.aspx?Item=N82E16816115072

Just tested this again with dsk speed and now my read speed is 205 megabytes a second- what gives?


EDIT - stupid just thought to check, is the PCIe 1x slots on the 790i ultra "2.0" or is that just the one x16 slot...

Can anyone confirm this?

Those cheap PCIe 1x card are complete crap. Leave the drive on the native SATA 2 port.

And use this to bench your SSD and post a screenshot of it: http://alex-is.de/PHP/fusion/downloads.php?cat_id=4&download_id=9

Quality software is always nice, the dsk speed thing did return similar results but this ui and functionality is great smile.gif
Heres some screenshots:

I tried once with the high point and once without.... not to much of a difference now.


When I first tested the M4 it was empty- had never been used AT ALL - literally just plugged it in and ran the test.. .so perhaps that is why its a bit slower now??? Dsk speed did read it at 245mbs last week....


Regardless- do i have any options for hitting true sata 3 speeds on this MOBO ? Really love this thing -solid board, easy overclocking...

You need a $150+ PCIe 4x SATA controller from say LSi.

Your speeds are slower because you do not have native Intel ports and you are dealing with NVIDIA for a SATA controller onboard. frown.gif
