Force 3 120 GB slower after new hardware
 
1 Attachment(s)
Hi

I am running at force3 120gb SSD on a SATAII ICHIOR AHCI controller...

I replaced the video card.. I honestly thought replacing the video card would not make a difference to it... I followed the guide when I installed it about moving page files and temp files, etc... got TRIM enabled... tried disabling it... made no difference to my speed..

On WEI I was getting 7.7 on the SSD, before I put the new card in...once I re-rated it the SSD was at 7.4 and was noticeably slower imo.

I have attached my ATTO speed test... I think its slow..compared to the other SATAII tests... could you guys let me know what you think?

Cheers...

Please post your system specs.

System specs as follows-

Gigabyte EX58-UD3R MB
I7-920 stock @ 2.67ghz
6gb DDR3
ATI HD7770 1GB DDR5
Boot drive- 120gb Force3 SSD
Data Drives- 1.5TB & 1TB WD + 250Gb WD

replaced ATI 4890 with HD7770 and experienced the slower WEI rating with SSD.

ATI 4890 was 7.2, HD7770 is 7.6

The ATTO test is normal for a SATA II chipset.

WEI should not be used as a benchmark as it is only a score that can decrease over time when technology advances.

Well I might have to upgrade my motherboard to SATAIII

Note that if you are buying a X58 motherboard with a third party controller, The controller may or may not run the SSD at the SATA III 6.0Gb/s speed.

Thanks for the info.. think I might upgrade my m/b & CPU, RAM.... and get another SSD and run it RAID 0...

A PCI-E card might help you instead of upgrading all the motherboard, CPU and RAM.

What sort of speed improvements will I likely see? if the card doesn't get full speed? I read on tomshardware that you can't really tell the difference between SATAII & III speeds... but from the ATTO speed tests done on SATAIII seems a lot quicker..

Hi mackaqld

Sata2 maximum speed is 300MB/s and sata3 600MB/s per-lane
Some controller have trouble to handle sata3 SSD speed
As the Marvell 9128 on some X58 and other Intel motherboard
Do to the speed limitation of the PCI-E 1x use as interface with the Marvell 9128 controller. So if you want to buy a PCI-E controller don't buy a 1x controller it will be no better. The best is a pcie 8x controller

ME i buy the Highpoint 2720SGL roketraid
It is a SAS to SATA controller with 8 sata3 ports
It theoretical maximum speed is around 2800MB/s, so with 6 sata3 ssd you reach the max speed
Not bad for lest then 200$
There iss my benchmark
1 ssd 536870MB/s write 573852MB/s read 0.03ms latency
2 ssd 938585MB/s write 1034931MB/s read 0.22ms latency
3 ssd 1388459MB/s write 1516957MB/s read 0.22ms latency
4 ssd 1740479MB/s write 1968964MB/s read 0.1,s latency
5 ssd 2176503MB/s write 2397934MB/s read 0.05ms latency
6 ssd 2403889MB/s write 2724221MB/s read
Up to 2800MB/s with a latency ove 0.04ms with AIDA64
you could see my post
