SSD is around 3 months old and I have had it closed to full on a number of occasions when I could not make it home to my USB backup drive. Have not noticed an iota of performance degridation.
 
C300 with original firmware. 150GB used, GBs rewritten daily, no slowdown, no issues.

I have been in contact with lloyd chambers, from diglloyd.com, and he has explained to me that XBench/Quickbench are pretty worthless for benchmarking drives. I think we're all wasting our time here :)
 
Here is one last benchmark with a C300 Firmware V 2.0 and no applications running in the background.

I am really happy my speed issue has been resolved from before

That's an excellent result ~~~~~ :eek:
 
Xbench isn't the greatest of benchmarks, but I'll play, here's my Corsair Nova V128. Not bad for $300. Was going to buy the G2 Intel, but wanted to save a bit of money, and I am not disappointed :)

Here is also a bench from Quickbench for larger files sizes:

Be careful of superduper transfers

Greets

Just an FYI: I used superduper to image the original HD to my new SSD in a 2010 MBP. For whatever the reason the SSD took a long time to boot. 40+ seconds. :(

Anyway, I reinstalled OSX (over the SD transfer) and now the MBP boots in 16 seconds from a press of the ON button. :D

xbench #'s didn't change between the original transfer and the OS re-install.

cheers

Dang, I'm not here to complain but I'm just concerned cause mine take about 35 seconds to boot. And I did a clean install and I'm only taking up 30gb of 120gb of space. I noticed that it takes about 15 seconds to reach the apple logo with the sprial... any comments??? Thanks. Oh and my drives xbench is two posts above

For my 64GB m225 SSD (with 17GB used and 46GB available) installed in a 2010 13" 2.4GHz MBP:
From a power-ON:
5 seconds to Apple logo
16 seconds to desktop

Before I reinstalled OSX the Apple logo didn't appear until ~ 30 seconds.

It sounds like you might want to try the OSX install again. This install won't disturb your current apps/docs and will take about 45 minutes including the download of the 10.6.3 update.

good luck and let us know if anything changes

Hrm.. d o you mean to just pop in the dvd again and just install over my current os? Btw I installed clean



edit:
so i googled it some more and most people who were experiencing slow bootup times on ssd drives didn't set their ssd as their boot up drive. so i checked my computer and it is. i noticed that most of the boot time is from pressing the power button:

black screen, optidrive sound, takes around 8 seconds
then another 8 seconds of gray screen

then 15 seconds of apple screen to boot.

I had exactly the same LONG HW init period as you're describing.

Yes, just pop the OSX disk in the drive and select the install option. Your data and apps won't be wiped out. Do the 'update' routine after the first boot. All I can say is that doing this OSX reinstall "fixed" the long power-on delay after I installed my SSD.

good luck

first off, let me just say thanks for the help and suggestions

sorry but if you dont mind me asking, how would reinstalling (not wiping, like you mentioned) help with the long boot time (black screen) hang?

I don't know what "could get repaired" but reinstalling OSX did "fix" mine. I doubt it will help but here's a link to list/description of what happens during an OSX boot process:
http://osxdaily.com/2007/01/22/what-happens-in-the-mac-os-x-boot-process/

The reinstall process takes less time than doing the research. :rolleyes:. If it doesn't "fix" the long boot time then you can crank up the research. :p

I will add that you should always have at least two data backups.

Edit: Go into System Preferences and Startup Disk and select the SSD as the start disk.

After seeing the results, I don't have as much regret not buying an Intel SSD and just going with Apple's. It doesn't have the numbers that Intel's does, but it works like a charm for me and is super fast. < 20 second total start up time and instant sleep recovery.
