What is the best raid stripe size for the X25-E and X-25-M?
Will the existing line of Intel SSD's be compatible with Windows 7 TRIM command? If so when is this likely to happen?
If TRIM is going to be supported will it be supported via RAID?
Is there any update on the new 34nm SSD product line? When will specs be available?
Will the 34nm technology use the same controller or will it be a new controller?
EDIT:
I can now answer part of my own question. After extensive testing with IOmeter I have concluded that a 128k stripe size is going to work best for raid 0 in the vast majority of cases, and certainly for normal OS use. That is based on test results using two different controllers and stripe sizes ranging between 16k & 1042k. (Tests on one controller were limited to 256k due to limitations of the controller.) This involved a lot of work, for something that could easily have been explained.
Intel....
you are currently dealing with enthusiasts in your new SSD market, who are interested in the technology and want to know as much as possible about it. Why have the anonymous corporate attitude to your new and exciting product line? Why is there the party line of saying nothing about such an exciting product? (Even something as basic as letting people know they should be using AHCI and not IDE mode).MS seemed to have learnt that this is not the way to go with all the fantastic work they have done with Windows 7. Enthusiasts are raving about Windows 7 and that is going to really help Windows 7 launch to the mainstream with maximum impact.
Every now and then it is good to throw your (loyal) dog a bone 😉

i agree, the X25-e is in another league...price also.
I wonder what 8 x25-e would do in a Raid0?

jeff, there is an anandtech review on eight drives http://www.anandtech.com/cpuchipsets/intel/showdoc.aspx?i=3532 http://www.anandtech.com/cpuchipsets/intel/showdoc.aspx?i=3532
Interestingly a 64k strip was used again.

8 of these in raid 0 will probably cause people to worship it. :S

Yes Redux, i believe they had problems with the Adaptec controller (cannot get in the website of Anandtech right now), so do not know which SSD's they used.
Odd....at Tom's Hardware they had problems with the Areca card and add to switch to the Adaptec 5805 card.
But they used 8 Memoright drives, no longer the fastest drives.....
I guess we have to wait for the Pram in a couple of years or a fast Raid drive from Intel?

Actually the key problem is not about the SSD. It's the SATA single port issue which Intel should be coming out with a interposer or "dongle" to convert the SATA into dual port SAS connection. We shall see how it goes when the X25-M & X25-E running at full duplex mode
