ssd raid 0 on M17x question

I'm wondering if it is possible to raid a samsung 256 ssd no TRIM with a samsung 256 ssd with TRIM support. any ideas anyone? anyone know the windows rating score with 2x256 samsung ssd in raid 0? My m17x with one samsung 256 is 6.7 for disk data transfer rate.

 

why do you even need raid 0 for ssd's? and also putting them in raid will disable trim. i highly recommend not doing this.

 

I've heard that Raid 0 when not using exactly the same hard drive is difficult. I've also heard that Raid 0 with SSDs actually decreases performance over time due to the lack of TRIM support in Raid 0. I haven't been able to find anything definitive, so I'm just bumping this hoping someone else has more experience. I'm toying with the idea of trying SSD Raid 0 as well.

 

if you want a RAID setup with SSDs, try not the MLCs than need TRIM support in order not to degrade in performance, but the SLCs. This way you won't need TRIM support either if you gonna use it RAIDed or unRAIDed. For instance the X25-E is SLC while X25-M is MLC.
If you can't afford the SLCs, you have to go with MLCs but you have to keep backup images periodically and unRAIDed them in order to clean them and restore their performance.
Be careful though if you plan to RAID two SSDs with different firmware, it may work, but it's risky (especially for data loss) and you may not see the expected performance...

 

How about the raid 0 setup standard from Dell with two 128 SSDs? Any information on the standard config?

 

It doesn't matter if it's Dell or not, MLC based SSDs without TRIM will degrade eventually.

 

I'd be interested in the Sony Vaio Z series dual and quad SSD raid 0 setup and support. Interesting to see how they dealt with the huge decline in performance after ~6 months.

I wouldn't Raid SSD's. You'll see no difference. If you really want speed then just buy a big performance single SSD and use that. Raid eliminates TRIM and eventually looses its Raid 0 advantage well within a year. Someone hear has the benchmarks, i know cause they showed them to me, haha.

 

the 128gb/256gb samsung ssds from dell is capable of updating firmware to support TRIM right? it's listed here: http://www.samsung.com/global/business/semiconductor/products/flash/ssd/2008/business/business.html

 

I figured RAID SSD would be a bad idea, but what about: http://www.newegg.ca/Product/Product.aspx?Item=N82E16820148349

Even though it's meant for SATA III, wouldn't it still be the fastest SATA II drive for the M17x? Price doesn't seem bad for such a large SSD.

 

That is awesome.

How does SATA I, II, III differ? It it just speed, or is it an actual physical difference in the connectors?

Would this HDD work with the stock M17x setup? If you can answer this I'll buy it today, LOL.

 

I know for sure that SATA I and II are interchangeable. It sounds like SATA III uses this SSD to it's full potential, but still maxes out SATA II's potential. SATA I and II have the same connectors, so I'm guessing SATA III won't need an adaptor. (Hoping someone more in the know will confirm) I'm hoping this is right, seems like a great drive.

Edit: http://www.tweaktown.com/articles/3...b_sata_3gbps_performance_analysis/index9.html seems like it's a solid choice for Sata 2 or 3.

 

So basically, in theory, we could eliminate degradation of the drives if this actually does what it says it does? Didn't have time to take a look at it since I have get up early tomorrow. Any thoughts on this?.

 

The motherboard does not support SATA III, so it will only run in SATA II
