    Greetings all,

    Purchased and installed a Kingston SSDNOW V100 / 256GB SSD in my SN12E2 and although it definitely seems snappier, I am getting horrible SSD benchmark scores. I installed as an image w/ the TrueImage cloning software that comes w/ the drive. There were several errors that popped up (which I didn't write down) but the process completed and the computer booted fine after install. I have verified that I am in AHCI mode w/ Hannsprees latest BIOS. I maintained the restore partition in the conversion but I did install Truecrypt 7.1 to encrypt the system partition.

    I have tested with AS SSD, Crystal diskmark, and ATTO all of which say I am getting sequential R/W around 80 MBpS w/ 4k reads around 14 and 4k writes around 34. The drive is spec'ed to read / write at 250MB/S which is a l o n g ways off of what I am getting.

    I know some of you are running SSD's on your hannsbooks which is why I am posting here... Does anyone know of any inherent issues w/ the Intel SU4100 chip that would be at issue. (As I indicated in my other post, Hannspree tech support said they did not support SSD's in this unit indicating only that "they don't work", but was very evasive when pressed for details.

    BTW, I have gone through the SSD optimization guide turning various items off and on, but seems to make little if any difference. defrag is OFF, prefetch / superfetch off, SSD always on, but I did leave write cache enabled after finding no change when I checked it off. Also have left my pagefile enabled since I only have the stock 2GB RAM. I have checked the alignment and it seems to be OK, with my offset divisible by 4096 (system partition begins at around 5GB d/t the recovery partition)

    Thanks for your input and suggestions!

    Could you please post a screenshot of AS SSD benchmark?

    Also, if you want I can move this thread to the SSD forum.
