Date: Wed, 14 Apr 2004 22:34:51 +0200 hi! i`m not really sure, but afaik this has been discussed and the problem is: rockbox shuts down the hdd to save power - and to really save enough power,the drive is put into a "deep" sleep mode which usually results in the interal disk-cache being cleaned. so it cannot be used for buffering. putting it into a "not so deep" power-save-mode to preserve the cache-contents would result in an overall bigger power consumption - bigger than that, what is saved from the fewer disk spinups as a result of the 8mb cache... maybe somebody can confirm what i said? regards roland ----- Original Message ----- From: "Joseph Jones" <joe_at_bumpycarrot.cjb.net> To: "Rockbox development" <rockbox_at_cool.haxx.se> Sent: Wednesday, April 14, 2004 12:09 PM Subject: Re: 8MB buffered hard drive could do? > I doubt it.

Is it possible somehow to exploit the 8 mb buffer for the archos? if so, we would have a unit with 10 mb without the 8mb mod! > > > > http://www.simply.co.uk/productinformation/49499/WW/HITACHI_2.5INCH_80GB_4200RPM_9.5MM_UDMA100_8MB/index.htm > > > > Bye, Cristian > > > > _______________________________________________ > > http://cool.haxx.se/mailman/listinfo/rockbox > > > > > _______________________________________________ > http://cool.haxx.se/mailman/listinfo/rockbox > _______________________________________________ http://cool.haxx.se/mailman/listinfo/rockbox Received on 2004-04-14 Page template was last modified "Tue Sep 7 00:00:02 2021" The Rockbox Crew -- Privacy Policy |
