although the home-use scenarios of RAID 0 or RAID 1 are well covered
Intel retracted that statement.

Is there TRIM support for RAID configurations?

Intel® Rapid Storage Technology 9.6 supports TRIM in AHCI mode and in RAID mode for drives that are not part of a RAID volume.

A defect was filed to correct the information in the Help file that states that TRIM is supported on RAID volumes.
This is reportedly from Intel

Quote:
It will support TRIM with SSDs in an AHCI configuration, or with the RAID controller enabled and the SSD is used as a pass through device. An example of this use case is for users that want to use the SSD as a boot drive but still be able to RAID multiple HDDs together to allow for large protect data storage – a great use for the home theater PC. TRIM support for SSDs in a RAID configuration is under investigation and is not included in Intel® RST 9.6.
Is Trim working?
Quote:
The Win7 command "fsutil behaviour query DisableDeleteNotify" command only shows, if TRIM actually is supported by the OS, but does not certify, that TRIM really is working.
This is suppose to tell you if Trim is actually working.

EDIT:
I found a MS Windows 7 article on SSD support. It's kinda long but the FAQ sections answers a lot of questions about the SSD setup defaults in Windows 7.

Engineering Windows 7 - Support and Q&A for Solid-State Drives

Quote:
There’s a lot of excitement around the potential for the widespread adoption of solid-state drives (SSD) for primary storage, particularly on laptops and also among many folks in the server world. As with any new technology, as it is introduced we often need to revisit the assumptions baked into the overall system (OS, device support, applications) as a result of the performance characteristics of the technologies in use. This post looks at the way we have tuned Windows 7 to the current generation of SSDs. This is a rapidly moving area and we expect that there will continue to be ways we will tune Windows and we also expect the technology to continue to evolve, perhaps introducing new tradeoffs or challenging other underlying assumptions. Michael Fortin authored this post with help from many folks across the storage and fundamentals teams.

In Windows 7, we’ve focused a number of our engineering efforts with SSD operating characteristics in mind. As a result, Windows 7’s default behavior is to operate efficiently on SSDs without requiring any customer intervention. Before delving into how Windows 7’s behavior is automatically tuned to work efficiently on SSDs, a brief overview of SSD operating characteristics is warranted.

I just purchased a new Dell Studio17, and have purchased a new Kingston 128G SSDNow V+ drive to use as the OS. The laptop holds 2 hard drives, so will use the 500 gig for storage. If someone wants to recomend benchmark software here, we can all use it as the standard for testing. And I would be happy to post my results when I get my system next week. My understanding is that the drive shipping now should have the "Trim" function that works with Windows7 to prevent the slow down problems. And the specs on the Kingston V+ look good. So.... I will let you all know.
So what software would be good for testing?

ATTO Disk Benchmark v2.46 is the latest version. It looks pretty good. I will use this. I should be able to run my test next week once I have my laptop.
Thanks for the info!

No problem. I was told that the AS SSD Benchmark is specifically for SSDs though. I have both.

Anandtech has some very good reviews and articles, my Brother told me about his site a couple of years ago.

Good review series on SSDs.

Hadn't read the Vertex 2 review yet, Thanks.

Looks like the SandForce drives are the top dog now, subject to the longevity testing. Intel is going to have to come up with something new.

This guy (Anand) does the best articles on SSDs not to mention other hardware. I love his site and have RSSed to it.

Thought I'd run some more benchmarks now that the drive's a few months old..

The AS SSD looks like it's slowing down a bit, the Everest looks good though.

Anything noticeable?

What drivers are you using?
