Great feature list (sata III, port multiplication feature, etc)
Weaknesses:
Causes a blue screen of death on all computers I have tried it with.
Summary:
Causes a blue screen of death immediately when inserted into the expresscard slot. I have tried this with 3 computers running: win7 32bit, win7 64bit, and vista 32bit. Hard-crashed immediately every time, even though the appropriate driver was up to date on all 3 systems.
It did not crash under Ubuntu 10.10, but i could not get it working properly in that OS either.
Not compatible with Macbooks or on Asus Netbook running Vista
Summary:
Wasn't recognized in my MBP even though it states it will run at 2.5.
Tried it in my netbook, Vista bsod on insert.
Going to exchange it for sata 2 adapter.
Can't really say much about it good or bad - just letting people know some information prior to buying it as there isn't much out there in the way of telling you whether it will work or not.
