Mac and PS3 compatible external HD?

Does anyone know a good external HD that will work well with both a Mac and PS3? I'd like to get a 1TB size HD. If not a specific brand, what specifications should I look for that will work for both?

hi, not sure if this will help you, but i upgraded the HD in my PS3. I took the old HD (60gb) and put it in a case. I can now use this on both the PS3 and the iMac. I also have a WD external drive. This also works on both my Mac and PS3.

They don't make a 2.5" SATA 1TB HDD as of yet.

The biggest 2.5" SATA form factor HDD is 640GB by Western Digital.
