Your Drives in raid 0 have a read speed of 2*275MBs= 550MBs <---you cannot achive the max gain from raid 0 with sata2

Feel free to correct me if im wrong
The 3Gbps (375MB/s) limit is per port so assuming there's no overhead in the RAID-0 controller, if you get 275MB/s on a single drive, you'll get 550MB/s in RAID-0. Of course, there's always some overhead so don't expect to actually hit those speeds.

That is correct. The next ceiling you would hit would be ICH10 which would be I believe around 700MBs correct me If I'm wrong.

Fair enough, so it seems to make sense not to set up a RAID 0.

If I'm not going to be doing that, then I will sell my current drive and buy a bigger one.

What is the best current drive in the $400 price range (and yes my board has SATA 6GB ports) in the 180 GB or higher range?

TRIM only prevents the degradation of write speeds. Usually write speeds are much less important for things like desktop use and gaming. Plus the Vertex have active garbage collection if you let them idle. I will be going dual Vertex 3 in raid 0 as soon as they are released. TRIM be damned!

Why would you need anything that fast, except for benchmarks?

TRIM is nowhere near as big an issue as people think. GC works fine on both Indilinx and Sandforce units. Realistically, once you start talking about RAID, the modest and highly situational performance gains from TRIM become irrelevant. Even with TRIM support, the block erase still happens in the background, so there is some delay before write performance is restored. If you're in a heavy rewrite scenario, you gain nothing as the drive doesn't idle long enough to handle those deferred erases anyway. And if you're not a heavy rewriter, the GC will take care of it sooner or later. It's all so moot.

Still think TRIM is the deal-breaker ?

Raid 0 vertex 2 for 8 months now, no problems, still 99% health.
post #19 of 20
I have a 128 gb c300 on sata 3 so no trim. I have been using it heavily (moving,installing and uninatalling games). I have had it for about 6 months and I have basically 0 performance degredation.

Granted the fullest I have ever had it at one time is 50% which helps a lot with GC.

i just bought another c300 64gb and going to raid them this would be my second ssd raid. the first raid was intel 64gb's ssd in a socket 775 sata2 it was fast. now with the sb setup i got now and 2 c300 64gb sata3 these will really fly. when i had the intel ssd in a raid it didnt degrade? i here people talk about this and lossing trim? i dont care i want speed.
i reinstall windows every 4-6 months to keep it tip top shape.

also revodrive ssd are amazing people talk **** about them to. i owned one and loved it.
the hdd in computers are the bottleneck in todays computers, since everyone can do over 4ghz with there sb, so with the new sata 3 raid them and let them fly!
