Would I gain any performance?

I just completed my new I7 Build! Yay!

Stats:

Main Board; MSI P55-GD65
CPU; I7-860 2.8GHz
Ram; 4 gigs 1333
2 P-100 32 GB Patriot SSD 210MB/s ; 150 MB/s

Left over from old pc

1 750 GB Western Digital HDD
1 500 GB Western Digital (used to be a my book, >.< but esata drive were so poor I made it internal)
8800GT
950 watt PSU
ETC...


I loaded Windows 7 on one of the p-100's but I don't feel like i'm getting the performance out of them i should be getting. (Windows boots in 50 seconds.) and I've followed all the advice from: http://www.ocztechnologyforum.com/forum/showthread.php?47212-Vista-32-64-SSD-Windows-Registry-tweaks but still it feels like its still a HDD in speed? and this is a fresh install of windows... would i gain anything from RAIDing my two SSD? Or is one fine?



Also I was wondering how can I have; My music, My documents , MY pictures...ETC default to a different drive? like my 750 GB HDD?


Thanks All!
 
RAID0 increases the maximum speed of large sequential accesses, by having half the data on each of two drives which can be accessed simultaneously. It basically does not affect small random accesses (the type of use you usually see when loading an OS) at all. If you were doing a huge transfer and it was pegged at the 210MB/s rating, then RAID0 should let you get a theoretical 420MB/s and alleviate that bottleneck.
 
The slow startup times are from using RAID. There's added checks when booting that slow down boot times compared to non-RAID systems. At least, that's been my limited expierence and info I've gathered from different forum postings.

To move the My *(music, video, documents,...) files, right click on the icon, go to Properties, and then go to the location tab. Then select a new destination. It's very simple to do.
 
Count your bootup time from after all the POST screens, once you see the first Windows message, how long does it take. I also second the questions regarding benchmarks. Stop all background processes, close all open apps and run a disk benchmark like crystal disk mark.
 
I'll run a bench mark tonight when I go to bed. I tried but it takes to long. And I have work to do tonight.

After all POST it's about 35 seconds.
Shut down also takes 35 seconds. My HDD could shut down in 15.... somethings not right.

What you say is true if you configured the striping RAID improperly.

If you properly configured RAID0, and use a proper engine, each I/O request is handled by ONE disk only; so the other disks in the array are ready to process different I/O requests in parallel. This will increase multi-queue IOps.

However, with too low stripesize, or stripe misalignment issue, multiple disks would be involved in a single I/O operation - causing loss of all potential random IOps performance - only one operation at a time can be processed. That means you lose all random IOps gains and only gain sequential I/O speed.

Properly configured RAID0 will increase both throughput (MB/s) and multi-queue IOps.

Any RAID that runs XP is likely improperly configured; since XP uses 31,5KiB partition offset that causes misalignment with the stripe blocks; leading to lower performance.
 
That's slow. It could still be something other than what you're thinking - services (including drivers, which are hidden services) must start during startup and stop during shutdown. If one of them is slow, it borks the speed big time. It could be something other than an I/O issue.
