New External HDD
Finally the exams over. So I went to Mong Kok and bough a external HDD, 500G with FireWire 800 interface.
Hooked it up with my Mac easily, it is already pre-partitioned and has utilities available on disk. So I did a little benchmarking with XBench. The result was satisfactory, reading operations with proper block size is as fast as those on the internal HDD.
