SATA3-1: Crucial M4 SSD
SATA3-2: WD Caviar Black 1TB SATA3 (D drive)
SATA2: WD Caviar Black 1TB SATA2 (formerly system drive)
SATA2: WD Caviar Black 500MB SATA2 (movies)
First, I installed the SSD and formatted it as a new simple volume with MBR and left it without a drive letter. Back to the BIOS

Here's my AS SSD benchmark score:

Compared to others with the same drive, my write speed is a bit slow and my 4K-64Thrd scores seem too low. I'm still a noob with SSDs, so I need some help with figuring out what the numbers mean and how I can possibly improve performance or if I should just let it be. The only reason I'm concerned is because my benchmark says 4 K - OK under the msahci controller, while others have 6-digit numbers. I checked my Partition Starting Offset in MsInfo32.exe and it's 4,096—which seems to indicate my alignment is correct. Disk Defragment is automatically disabled for the SSD and I enabled TRIM with -fsutil behavior query DisableDeleteNotify through the command prompt. I also installed the Intel Rapid Storage driver but it looks like Windows is still using the default drivers (msahci).
So based on all that verbal diarrhea, does it look like my SSD transfer went without a hitch or can I still squeeze some better performance out of the drive?
