Great results with X25-E 64Gb in Windows 7

Hi. I don't want to be contrarian, but I did want to post a positive comment in this discussion group.. People have a habit of only reporting problems, and casual observers may not understand that this reflects that the majority of users are having no troubles.

I installed my x25-e 64Gb a couple of months ago to "celebrate" the RTM of Windows 7 (obtained via Technet subscription). My motherboard is an EVGA nForce 790i Ultra SLI with an Intel QX 9650 overclocked to a conservative 3.6Ghz to minimize heat issues.

I clean installed onto the new drive, it went perfectly the first time, zero issues, fantastic speeds.

Using standard benchmark testing, this drive exceeded its advertised read/write speeds!

For what it's worth, the Windows 7 "Performance Index" score for this drive in my system is 7.4 .

Thank you Intel ! /jim

Interesting.

With an Intel DP35DP motherboard and an E6850 Core 2 Duo at 3GHz, My X25-E 160GB has a Windows 7 (64bit), disk score of 7.8

My guess is he is using IDE mode. A fresh X25-E should get 7.9 using 7/64. Once degraded that might go down to 7.8. Anything lower would imply something is not right.

A fresh X25-M in AHCI mode will get 7.8/ 7.9. A fresh X25-M in IDE mode will get 7.5

I just tried the drive in AHCI and my performance score dropped from 7.4 to 6.9 .

EVGA tells me the AHCI implementation on my motherboard (790i Ultra) is not too swift, so I'm not surprised. I did load the latest JMICRON driver from their website as well..

I'm gonna stick with my 7.4 and be happy for now, unless you have any ideas for me.

I've run an X25-E on a ICH9 mobo and the worst (degraded) score I ever got was 7.8. I'm not sure what you are doing.

Are JMicron drivers on your mobo for the eSATA ports? The SATA ports are 3.0Gb/s and would need Nvidia drivers. I have no experience with SSD's & Nvidia but somehow your drive is being gimped.

I would seriously consider getting a ICH10 board if I had spent that much money on an SSD to end up with that score.

Very interesting,

With an X58 motherboard, a 920 i7 at stock clock and an X25-M 80GB MLC G1 SSD i get 7.8 disk score in W7 64 bit...

I have an Alienware M17x | T9600 @ 3.41 GHz OCed| and the score I get is 7.7 with AHCI on clean install of win 7 x64

I switched to either AHCI legacy or native and I still get the same results. The other options I have on BIOS are either RAID or ATA.

The Crystal diskmark gives 4K random reads only 20.30 MB/s and I don't know if something is wrong with my system or the SSD. I upgraded to the latest firmware 8850

The chipset is NVIDIA nForce 730i according to CPU-Z

Thanks

*EDIT*

The chipset is probably the bottleneck since I cannot exceed the 7.7 WEI no matter what drivers I use or offset (1024 default win7 or manual set to 64)
