30GB Blu-laser storage tested: Plasmon UDO30D-SE
 

It is interesting to see the difference in performance between small files and larger files. At 16k and 32k, the throughput (Read MBps) does not differ by much with 2.12MB/s and 2.13MB/s respectively. For 512 bytes however, it drops to 130kB/s. A similar pattern appears with total amount of bytes read, where for 16k and 32k the figures are fairly close at 636Mb and 638Mb respectively, while for 512 bytes, the corresponding figure is only 39Mb.

The last test we put our UDO drive through was to copy a full DVD movie to the drive. We used DVD Decryptor to copy Gladiator from a Pioneer DVR 108 drive. The process was completed in 1:00:40 with an average read rate of 1,974 KB/s (1.4x) and maximum read rate of 4,167 KB/s (3.0x). As a comparison, the same process but with the copy being written to the Western Digital Hard Disk, had a duration of 00:24:40 with an average read rate of 4,857 KB/s (3.5x) and maximum read rate of 6,949 KB/s (5.0x).
