[gentoo-user] Do I need hdparm for serial ATA drive?

[gentoo-user] Do I need hdparm for serial ATA drive?

[Mick]

Newer machines invariably have SATA drives:

           *-disk
                description: ATA Disk
                product: ST9500420ASG
                vendor: Seagate
                physical id: 0
                bus info: scsi@0:0.0.0
                logical name: /dev/sda
                version: 0004
                serial: 5VJ377P2
                size: 465GiB (500GB)
                capabilities: partitioned partitioned:dos
                configuration: ansiversion=5 signature=cf5ac2f0

From dmesg:

ata1: SATA max UDMA/133 abar m2048@0xf1005000 port 0xf1005100 irq 35
ata2: SATA max UDMA/133 abar m2048@0xf1005000 port 0xf1005180 irq 35

Do I need to emerge hdparm for such a drive?

As long as the drivers are in your kernel the drives should work.
hdparm is not required to use your disks, but you can use it to change
power-saving mode etc. (for example my 2TB drive had very aggressive
spindown when power-saving was OFF, but when I use hdparm to turn
power-saving ON at the highest level, the crazy spindowns stopped)

% whatis hdparm
hdparm               (8)  - get/set SATA/ATA device parameters

SATA is still ATA, using the same basic command set but over a different
wire.

Yes, hdparm will work with my drive, but the question is would I have a 
benefit using it?  Other than what Paul said, is there another benefit e.g. 
speed wise that I could derive from using hdparm, or is the kernel on its own 
enough to optimise the performance of the drive?
