SSD Speeds?

Hey guys,

I just recently installed a Samsung 830 256gb SSD in my early 2011 13" MBP and ran a speed test. My results showed 397MB/s write and 475MB/s read. I am just curious as to how fast this is compared to other SSD's (mainly to Apple's SSD's in the MacBook Air/MBP Retina). What are your guys' SSD speed test results? (I used Blackmagic Speed Test from the Mac App Store)
