External Harddrive question....? - best external harddrive brand

I am looking for an external hard drive, and I usually know what I want; 160-250 GB, USB 2.0 (firewire and if possible) to a buffer zone of at least 5.0 MB (preferably 8), transfer data ( well) 480 Mb / s and a coverage period generally.

I have a Seagate one (I've heard it is one of the best brands), but recently discovered a brand called "Beyond micro" ... Anyone who knows anything about this? If not, the other brands that are good! (in addition to Seagate)
