There's a long thread about it on 2cpu.

I abhor having to log on to any website.

said by sdgthy :

Be aware many of those on 2cpu are using top of the line RAID cards, so depending on what the Gigabyte board has, you may not see as impressive of results.

said by sdgthy :

All that is meaningless, all that matters is:

South Bridge: Intel® ICH10R

I connected 8 usb thumb drives to my pc and used each one for swap file space and my old pc is like new again.

Hahahaha!
Anyone ever raided a usb thumb drive before?

said by Anonymous_ :

well on a cheapo nvraid card i can get 200+MB/s read rate

190MB/s write rate on sata1 (quad raid0)

said by sdgthy :

It means you could see some decent transfer rates with even a cheapie RAID controller. But if you're hoping for rates near the high end of what is shown in that thread above, you'll need to pay attention to what controllers are capable.

I easily get 200MB+ reads with my Arcea card and a SATA RAID5 array.

Actually I am just hoping to decode the meaning of the graphic in the howie post

Hum, how about what xfer rate should a bird with modest means ..
.. expect from just TWO SSD's in Raid-0 on a Gigabyte mobo for intel 775, please?
How about the 1366?

I can't believe the blokes in that video ran defrag. *sigh*

said by Gordo74 :

His point is, you shouldnt run defrag on a SSD because it's completely useless and it uses up read/write cycles.

said by Martinus :

OK, so what's better? SLC or MLC?

said by koitsu :

Regarding SSD lifetime, this explains it, and this should put your worries to rest.

said by GigabyteSupport :

Customer Q: After updating to latest bios there is a new option in Bios setup menu called the “SATA AHCI mode”, does this mean Intel ICH8 supports AHCI function?

Support A: Only Intel Southbridge chipset model names that include a R/DO/DH will support AHCI and RAID functions. The function ICH8 AHCI can only be enabled under Vista. If you are using Windows XP/2000 please disable the function “SATA AHCI mode” in bios.

Hello!

I would like to know if Intel is aware of the issues with SSD's and RAID arrays regarding the lack of TRIM capability. More and more SSD drives support the block cleaning/optimising method aka. TRIM. Windows 7 has the operating system level support for it. As far as the user useres his SSD's in normal SATA/Legacy IDE mode this TRIM methid works because the OS can send the TRIM method calls directly to the drive itself. But if the user's SSD drives are in a RAID0 array TRIM capabilities are gone, because the Intel RAID controller does not pass through the TRIM method calls.

My question is that whether Intel is aware of this problem and if is there any effort to solve this issue? Are we seeing any driver updates soon?

Thank you in advance!

Regards

Jozsef,

I personally wouldn't be too concerned with the TRIM capability to begin with, especially in a RAID configuration. There won't be a whole lot of performance gain since these SSDs are already very fast. Aside from that, your RAID controller is where the performance enhancements should be looked at. Are you using a RAID controller with a built-in cache? If it's an on-board RAID controller, probably not, and you won't see much performance gain by using RAID on these controllers -- just redundancy gains. I currently have an Intel-based RAID ICH10R and under all configurations of RAID 0 or 1 with two X25-E drives, the performance didn't change much from using just a single drive. I ended up buying an Adaptec card (the 5045) (sic: 5405) to see true gains. Perhaps it was a combination of the chipset and motherboard, but unless you are writing hundreds of thousands of tiny files, I don't see where your benefit for this feature would amount to much.

Personally, I feel the TRIM command defeats the purpose of wear-leveling, sacrificing lifespan for very little performance gains (there have been exceptions). Maybe there's still a significant difference for the X25-M series, but I've never used those. Anybody have links to some more information regarding TRIM benefits on the M series with the updated firmware? Other brands of SSDs wouldn't fit this topic.

Hope this helps.

said by Jozsef Dubravszky :

Thank you for your response but I think you might not get my point. I am not too muck into performance gains. The problem is that SSD write speeds degrade as you write more data on the drive. It is no concern with NAND chips wearout it is a matter of the method that SSD's use for writing and overwriting data. You can describe it as a kind of defragmentation but it is not that simple. You should check on this article if you are not sure what is TRIM: »anandtech.com/storage/showdoc.as···531&p=10.

If you do not get any performance increase with RAID0 you have obviously going wrong.

TRIM support is more likely to be solved on the RAID controller's side.

said by m.oreilly at Intel :

william, it seems you are unawares of the multitude of mlc drives that are available do experience performance degradation w/o the sort of "cleanup" trim offers. regarding raid, i certianly notice the speed difference between using a single drive and 4 in a raid0 array, and would really like to have discard/trim support on my intel based workstation ich (which uses system ram for cache, if i'm not mistaken), which by the way offers very good performance (up to and including x4 ssd) compared to the adaptec you stated you have (i also run one, and the ich option performance is quite close). mlc drives are a bit different than the slc, and can really benefit from trim/discard. even slc can experience similar performance degradation effects over time w/o it's implementation.

the ticket...(referring here to the Adaptec 2258100-R PCI-Express x8 SATA / SAS (Serial Attached SCSI) 5405 Kit Controller Card RAID levels 0, 1, 1E, 5, 5EE, ... - Retail)
»www.newegg.com/Product/Product.a···16103096

Pros: tapping 900 reads and 680 writes w/this and 4x 30gig vertex drives. this is "the little card that could": 1.2ghz intel 348 iop, barebones card at stupid low price, one of the few inexpensive hba options that handles multiple raided high throughput ssds. nice to see newegg has this card in stock.

Cons: might not be for everyone's system, as your particular mobo bios/irq headroom/smb situation may not play well w/the 5 series or similar cards from other manufacturers.

Other Thoughts: that said, these are selling like hotcakes, and being used in high performance ssd raid arrays on varying system platforms with very positive results. until sata III/sas 6/pci-e drives are available, this is the ticket, and an inexpensive one at that...

said by Anand Lal Shimpi :

Every controller manufacturer I’ve talked to intends on supporting TRIM whenever there’s an OS that takes advantage of it. The big unknown is whether or not current drives will be firmware-upgradeable to supporting TRIM as no manufacturer has a clear firmware upgrade strategy at this point.

I expect that whenever Windows 7 supports TRIM we’ll see a new generation of drives with support for the command. Whether or not existing drives will be upgraded remains to be seen, but I’d highly encourage it.

said by Anand Lal Shimpi :

with support for TRIM hopefully arriving close to the release of Windows 7, it may be very tempting to wait. Given that the technology is still very new, the next few revisions to drives and controllers should hold tremendous improvements.
