Yes, unfortunately Audya is USB 1

I may wait till my 1 year warranty is up to do this HD swap

But the advantage is no moving parts, especially useful for the Audya4, the module, as you can have it at ANY angle with SSD and be ok

The other advantage is you'd have a backup of your Audya so in case your SSD stops working, it's just a matter of swapping out for your original HD, and you're quickly back up and running

AJ, any others positives with the SSD ??
