Intel x25m G2 Speed - Is mine up to par?

Hi Everyone -

Just installed my new Intel 160 GB x25. So far I have to say I am not in the "blown away" category I was expecting to be. Boot time is around 20 seconds, but I expected Word, Entourage, etc to open in one bounce and sometimes I get 2-3 bounces. I can't help but wonder if I did something wrong. I zapped PRAM after the install, I updated the firmware and I see 3 Gbps on the controller. Am I missing something?

I am also considering running xbench to get my speeds, but am concerned with how much wear it would put on my SSD - should this be a concern?
 
If you're concerned about wear, just stop using the computer. A very simple solution.

If you poke around a bit, you'll learn that the X-25M G2 with the new firmware takes care of write degradation very nicely. You'll also learn that doing a sequential write operation of a large file will actually help clean it up. Please see the following thread for details

http://www.anandtech.com/show/3618/intel-x25v-in-raid0-faster-than-x25m-g2-for-250/6

And do yourself a favor. Just use your computer and don't worry a single bit about write degradation. You'll never notice, seriously. Run xbench, post the results.

the random 4K results are pretty impressive!
does anybody know if it's possible to set up a raid0 on mpb 13''/15''?
the system i've got now performs decently on win7,
but working on OS X would be better.

can the OP, or anybody else, run a matlab benchmark with SSD
 
FWIW, last night I reformatted my old MBP in preparation for selling it. Since I had to reinstall OSX on the Intel SSD too, I was able to compare the time it took to run the installer and Software Update on both machines. The old MBP (with 5400rpm hard drive) definitely took much longer to install updates than the new MBP with SSD, but there wasn't much difference in times when installing 10.6.0.

I've also noticed that Time Machine backups over the network go much faster from the SSD drive--in fact, Activity Monitor showed peaks around 12MB/sec. I wouldn't worry too much. :)
 
I don't have the link handy but if you MROOGLE something along the lines of "SSD TIPS", it should pull up a few tweaks that let you optimize having a SSD in your baby rather than a normal magnetic HD.

On my SSD, upon powering up from OFF (not sleep), once the screen goes from black to grey, I'm on my desktop within 7-8 seconds.

Which SSD do you have, is it the intel?
 
Could any kind soul please tell me / refer me a link to how I can find out the firmware version of my Intel X-25M G2 SSD and how to upgrade it on a Mac ?

Thank you.
