Post your GSkill drive benchmark result here please
It's quite clear that performance can be rather erratic. There is no clear pattern between 64GB or 128Gb posted so far.
Tonight I started playing with differences between IDE and AHCI. After enabling AHCI as per the Microsoft Knowledgebase (http://support.microsoft.com/kb/922976) things became interesting.
1. Access time increased from 0.1ms to 0.2ms
2. CPU Utilisation increased
3. Burst rate dropped
4. Speeds dropped
5. I switched back to IDE to see the difference
6. Performance became erratic with the minimum dropping from 190 MB/s to 61MB/s and the HDTune graph was all over the place.
7. I ran my first TRIM command as an experiment
8. Mimimum transfer speed increased to 71 MB/s, maximum jumped to almost 240 MB/s and burst jumped to almost 188 MB/s. This is under IDE mode with access time back to 0.1ms and CPU Utilisation at 1.4%
9. Switched back to ACHI to notice slower access time, burst rate and increase CPU Utilisation. Minimum jumped up to 97 MB/s but maximum was down to 218 MB/s.
10. I then ran my second TRIM command and under AHCI the minimum speed under AHCI went back up to 190MB/s but maximum speed will not go over 218MB/s. Access time remains at 0.2ms with higher CPU Utilisation.

Speeds are going to vary quite a bit from system to system, depending on the configuration. The biggest thing to remember is that the advertised speeds are the highest speeds their engineers have been able to produce under (in their own words at various times to me) 'ideal' or 'perfect' conditions, which basically amounts to a new install on a clean system, for tips on increasing speeds and optimizing your drives I've made a few posts here, but the OCZ forums have a much larger, more knowledgeable user base and can provide more info. I purchased 2 of their MLC 64GB drives early on and was totally dissatisfied to the point of filing a BBB complaint about the advertised capabilities of the drives and their support - They never responded, which dropped their BBB rating.
Pls offer comments on support I provide, HERE, in order to help me do a better job here:
Here's my benchmark with Atto, 2xFalcon 128GB RAID0. Interesting thing is the write speeds are faster than read at small transfers. 483MB/s max though...sweet!
Here are my results from my 2 Falcon 128GB drives. I am using a gigabyte x48-DS5 onboard intel raid. I did have problem with the iastor.sys driver causing errors but i eventually fixed them and got these results.
OMG... I decided to load the new firmware, so after installing windows 7 rc 64bit and installing all the drivers, I ran CrystalDiskMark, and people, my results are outstading, reads are close to 250MBps I'll post screenshot! Love this drive!
Why my drive is half slow? i run different benchmarks.
the small size read /write looks ok. but large files are half slower.
I did partition aligment and wiper.
do i have to install windows 7?
windows xp sp3
macbook pro 13.3' 2.26G 2G RAM
Falcon 128G ssd fw:1571
please help me.
It might be that your onboard SATA Controller is only SATA1, 150MB/ps and not SATA-II. How old is your PC? Check your SATA AHCI Drivers, if you have a Intel Chipset, install the latest Intel Chipset Utility Software Driver...

thanks FaNIX. Will give a try later today. My is the latest macbook pro(released this week.).I use the latest bootcamp installer dvd. it should have the latest sata driver. How could i tell it's in SATA1 or sata2 mode?
thanks
