IntelliPower - What does it mean

jakelovatto · 19 Oct 2008 at 01:26

Can anyone give me a better explanation than

"A fine-tuned balance of spin speed, transfer rate, and caching algorithms designed to deliver both significant power savings and solid performance. Additionally, GreenPower drives consume less current during start up allowing more drives to spin up simultaneously resulting in faster system readiness."

Thanks. I'm considering buying two (cheaper than a 10,000 rpm) and RAIDing them. I was wondering whether I would get comparable performance.

Thanks

Are you planning on buying Velociraptors or GreenPower drives? They don't do GP VRs.

You mean 2 GreenPower drives in RAID 0 versus one 10,000rpm job?
If so, depending on the exact drives, you will see similar-ish transfer speeds but much higher access times on the GP RAID 0 setup. There's also the issue of data loss in a RAID 0 setup.
I would personally go with one 10,000rpm disk.

Western Digital VelociRaptor 300GB 10000RPM SATA-II 16MB Cache
v
2 Western Digital Caviar Green 1TB SATA-II 32MB in raid 0

But considering the potential for data loss I was also considering

4 Seagate Barracuda 7200.11 500GB SATA-II 32MB Cache in raid 10

Any Ideas? Power consumption is an issue.

The basic principle of IntelliPower is that the drives spin at 5400RPM to start with. Should more performance be needed they will spin up to 7200RPM.

thing is no drive has a variable spindle speed. its still fixed at either 5400rpm on the green power drives or 7200rpm on the non greenpower drives. raptors are still at 10k.
