PS3 Backup in the Palm of your Hand
CVG has a how-to guide on making a Corsair FlashVoyager PS3 compatible. While not the most cost-effective solution on the block, this 64GB Flash Drive fits in the palm of your hand and should be able to backup most 80GB PS3 consoles’ data. The only caveat is you need to format this puppy for 64GB in FAT32. Generally that isn’t possible with Windows’ format utility. HP has a format tool that fits the bill.
