Hi, I read that the Intel X25-M SSD consumes less than 0,3W during typical usage if DIPM is enabled. This would give noticable power saving even compared to a spinned down hard disk. I checked the hdparm -I output on my notebook with the current hard disk, and it shows this: * Device-initiated interface power management When searching for the corresponding hdparm output with X25-M in google, I found only hdparm output with this feature unset. What can I expect with a X25-M on my hardware regarding DIPM? It is a ThinkPad X61s, lspci shows this: 00:1f.2 SATA controller [0106]: Intel Corporation 82801HBM/HEM (ICH8M/ICH8M-E) SATA AHCI Controller [8086:2829] (rev 03) Please CC: me in replies, as I'm not subscribed.
