I was thinking about the Western Digital Caviar Green WD5000AADS 500GB Which newwegg has for $49.95 free shipping. The WD util seems to be only for certain models and they warn against using it on any others. This model is not included.
>From the wd site.... This firmware modifies the behavior of the drive to wait longer before positioning the heads in their park position and turning off unnecessary electronics. This utility is designed to upgrade the firmware of the following hard drives: WD1000FYPS-01ZKB0, WD7500AYPS-01ZKB0, WD7501AYPS-01ZKB0. This is for util - wdidle3_1_05.zip So not sure wether this drive is a good choice or not. I am not sure what the stock head park time is but I guess you could always cron something to access the disk at a higher rate than the park timeout. There is a really confusing amount of stuff out there about the new drives and Linux!

I've got a WD Caviar Green (WDC WD20EARS-00MVWB0), 2TB version in my Thecus. currently I do not see any problems with it, beside that you have to make sure that you re-configure it with a WD-supplied tool to tweak some power saving setting (the timeout until the heads are parked, to be more detailed), otherwise the "Load Cycle Count" will go up pretty fast, exceeding the lifetime spec of this parameter quite fast. (NB: I had to RMA the first one I got, it had bad sectors out of factory and the RAID didn't sync because of this) > I am also interested in experiences with flash drives.

On the same machine I use a SanDisk Cruzer 8GB stick for /var/log (fs: ext2). It is now one year old and shows the first bad sectors. > I suspect one of the other small arm devices with more RAM might be a better > choice if you were using a flash drive. > -- To UNSUBSCRIBE, email to [email protected] with a subject of "unsubscribe".
