Hey,


Does any one know the requirements of running a sata II harddrive??

Lol i know i need a sata enabled harddrive. I also know i need a sata power plug + a sata enabled motherboard.

But what about power?? Are sata drives power hungry??

These are from very similar size Samsung drives. Should give you an idea of the requirements vs. a standard IDE drive.

Standard IDE hdd

Voltage +5V±5%
Spin Up Current (max.) 5.0W mA
Seek4 (typ.) 2.4 W
Read/Write On-Track (typ.) 2.4 W
Low Power Idle (typ.) 0.85 W
Standby (typ.) 0.25 W
Sleep (typ.) 0.1 W

SATA hdd

Voltage 5V°±5% / 12V°±10%
Spin Up Current (max.) 820 / 2250 mA
Read/Write On-Track(typ.) 8.5 W
Seek2(typ.) 9.5 W
Idle(typ.) 7.7 W
Standby(typ.) 0.9 W
Sleep(typ.) 0.9 W

SATA2 hdd

Voltage +5V±5%, +12V±10%
Spin Up Current (max.) 650/1900 mA
Seek (typical) 9.5 W
Read/Write (typical) 8.0 W
Idle (typical) 7.5 W
Standby (typical) 0.7/1.5 W
Sleep (typical) 0.7/1.5 W

Hope this helps.

You could also use this PSU calculator, its the best I've found so far.
Its just depressing when you get a reading from it saying that you need at least 828 Watts from your PSU.(No wonder my electricity bill is so high!)

Its reading shows a 7200rpm SATA drive uses about 13Watts, compared to a 7200 IDE using 15Watts.
