Date: Sun, 06 Apr 2003 17:22:02 -0800 I have been interested in upgrading to a larger drive, however, I have found the spec. sheets to be insufficient in comparing the real-world performance of the drives for this application. possibly a database could be created with which to compare drives different people have tried using some quick tests such as: - recording with standardized settings, no input to compare electrical noise. - with mic enabled to compare acoustic noise. - some test to compare succeptability to shock. - possibly real transfer rates... I personally am bothered by the noise of the machine. Playing quiet music late at night, the electrical interference when the drive spins up is annoying, the frequency of spinup/down is distracting, and as we all know, the builtin mic is close to useless. So I am interested in the drive that can make the best compromise for these purposes (but others may want to make different comparisons). Having made this suggestion, I must say that being able to employ the builtin cache on any drive would override all these considerations as the majority of songs would be playable without spinning up, and recordings of substantial durration would be possible without spinning up, making it usable as a note-taker that would be usable with voice recognition sw: spin down disk -> press rec -> record possibly 30min speach with 16mb buffer, low bitrate, possibly with time-machine record option. I have no idea how to begin investigation into this matter. any suggestions? The problem, I gather is that the cache data is generally not read/writable when the disk is spun down? is this universally true? Also is is possible that some drives have acoustic management features that involve varying the rotational speed of the platters, so that they might spin only slightly faster than neccesary to supply needed data, possibly reducing, and rendering less-eratic the noise of the drive. my machine uses toshiba 20gb drive. -- zeno_at_warpmail.netReceived on 2003-04-07 Page template was last modified "Tue Sep 7 00:00:02 2021" The Rockbox Crew -- Privacy Policy |
