Pros: Attractive case. Runs quiet and cool. Inexpensive.

Cons: Power "switch" (actually a touch-sensitive spot on the base) behaves erratically. Has a spin down issue on Linux systems (see below).

Overall Review: There is a problem with the Seagate FreeAgent drives on some Linux systems: by default, the drive is set to spin down after 15 minutes of idling. When the system asks the drive to spin back up, it does not respond quickly enough, errors out and, gets re-mounted read-only. It is possible to set the drive to never spin down (with sdparm) though, that may cause other problems. Some (but not all) systems can be set to allow the drive more time to restart. None of these work-arounds are needed with competing USB drives from other manufacturers.

Pros: I have no idea if there is anything good about these since they are unusable in the system for which I purchased them.

Cons: These modules are 35mm taller than standard RAM modules, making them unusable in some systems (Shuttle XPC systems, for instance).

Overall Review: I am posting this review so others won't have the problem I had: suddenly discovering that they were an odd form factor and won't fit in the system I am building.

Pros: Seems to be a pretty solid heir to the Intel Shuttle throne. No unexpected problems.

Cons: The power supply makes a buzzing noise as soon as you turn it on, even before you press the front power button to boot the machine. That gives me an uneasy feeling, though it has led to no specific problems, yet. Mounting the cooling system on the CPU is a little funky. You have no wiggle room to spread heat sink compound as suggested by some products' instructions.

Overall Review: I have been building Shuttle systems for several years and, have deployed over a hundred of them. This one seems to be the best Shuttle currently available (Summer 2007).
