Various questions regarding SSD

[idata]

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 can maybe understand why they don't want to say anything about the new gen drives, although quite a few clues from Intel already exist, but the current drives are released products and all I am asking is a question about functionality. A good product talks by itself and the X25's are an exceptional product...but a little more info for end users would be helpful. Intel don't seem to be so shy when it comes to cpu's

@ redux and other Intel SSD Enthusiasts

Greetings from the NAND Solutions Group inside Intel!

First, we appreciate your support and enthusiam for our product. We believe we have the highest performing and most reliable SSD in the market today.

To address some of your questions:

• We are currently looking at product intercept timelines for TRIM capabilities. Look for updates during announcements for upcoming product lines.
• As you can imagine we have had a lot of interest in our new 34nm technology. Detailed specs will be available when product is released.
• We recognize your comment regarding optimizing our drives. Thanks for the input, as we're always looking to improve user experiences with our products and documentation.

We appreciate your loyalty and would love to throw each of you a specific "bone". Though we can't release "bones" in a public blog, stay tuned for upcoming product announcements.

Thanks for the feedback.

Could you maybe please explain a bit more about how the X25-e works with raid 0? I appreciate this is normally an issue primarily related to computer use, but obviously ssd works quite differently to hdd and it would be really interesting to understand the issues related to the X25-e.

For example, I've tried various stripe sizes and anything between 64K & 256k works quite well, but smaller stripe sizes seem to really have a negative impact. Why would that be the case? Do smaller stripe sizes have a detrimental impact to wear levelling and write amplification? I'm not looking for an insight into how the technology works (although that would be nice) I'm just trying to understand how to use the product to its best ability.

Good luck with the 34nm technology. I've heard that it will be quite a feat of engineering and I'm really looking forward to its release.

ps....does "look for upcomming product lines" mean no TRIM suppport for existing product lines?

Hi redux, may I know how many X25-E do you have in your RAID 0 disk array?
