Get the Western Digital Caviar Black WD5001AALS, it's cheaper than the green with free shipping at newegg, and has a 5 year warranty. The WD site doesn't show the Green's speed, and if I remember correctly the Green series is 5400 RPM, which results in slower read/write speeds.
The Green drives are slower, but use less power and have an Enterprise-class data integrity rating (1 unreadable sector per 10^15 bits read vs. 1 per 10^14 for most of the other consumer class 7200rpm drives I've seen).
Choose the Green for bulk storage if performance isn't important, otherwise choose a 7200rpm drive.
Yes all Sata ports are enabled and set on AUTO detect.
at the moment I have removed one Sata-1 HDD, and now I have this:
TWO IDE PATA
one master ( bootable active partition with OS ) MAXTOR 40GB
one slave ( no bootable active partition, no OS only Data) SEAGATE 40 GB
ONE SATA -0
Sata-0 HDD seagate 250GB
ONE SATA -1
Sata-1 DVD Writer TSST corp.
Sata ports configured for HDD as AHCI enabled.
BIOS-> Boot priority-> HARD DISK, DVD, Removable.
in this case IDE MAXTOR boots first, then Sata-0.
To forcefully boot from Sata-0, I have to:
1.disable IDE onboard ports from BIOS
2.Mark Boot partition as inactive and hide boot partition on IDE
3.remove IDE cable from both IDE drives.
Only in case of 2. I am able to boot from Sata-0 and still able to see IDE partitions in Sata booted OS.
Suppose I populate this:
IDE HDD master + slave two HDDs , master with bootable active bootable partition.
Sata-0 HDD with bootable partition
Sata-1 HDD with bootable partition
Q. What is the easy way to go , to boot selectively from the drive/partition of my choice between IDE master, Sata-0 and Sata-1 HDDs?
as stated above, If I disable IDE onboard from BIOS, my IDE is still connected and set, no need to open the case to remove any cables. BUT I am unable to see IDE partitions in Sata booted OS.
another thing, suppose IDE is out of question ( assume not installed) now to selectively boot between Sata-0 and Sata-1, ... :
hard crude way: swap the sata-0 and sata-1 cables, since sata-0 HDD will get priority first
but to do this, I have to open the case everytime.
