CHAPTER 4: Thermal Specifications
Library Bezel
This section lists empirical temperature data from measurements taken while using
the library bezel.
Again, the results show similar components running hotter in 320 mode than 220
mode. The HiFN (compression chip) is slightly hotter and the Hydra chips (read
channels) also run hotter. Overall, the drive running in 220 mode parallels the
drive’s performance when running in 320 mode for both the embedded and library
bezels. For both bezel types, there is little to no difference in the tape path
temperatures.
