advantage and disadvantage of dual hard drives for new lapto

by gklein / May 2, 2007 9:13 AM PDT

planning to purchase new laptop offering a choice of a dual hard drives - SATA (120gb x 2) at 5400rpm or 7200rpm.

1. does dual HHD use more battery power ?
2. generate more heat ?
3. increase or decrease performance speed ?

I am not interested in RAID or the backup function ?
My storage needs are modest pictures and music.

Thanks,
Gene, Bradenton, FL

yes, dual HDs use more power and more heat

i see dual HDs as a marketing ploy mostly. if you really need that much space (>120gb) then get a NAS or external USB drive.

Don't bother

If you're not planning on using RAID and don't really need the storage, don't bother with the extra HDD. It will cause a bigger drain on the battery, and it will create more heat, though it won't affect performance at all. If it's a laptop model that can have an additional battery in the bay where the second HDD would go, THAT might be a worthwhile upgrade.

Also, keep in mind that while higher RPMs on drives does make for somewhat improved performance, it will also cause more heat dissipation and a bigger battery drain to keep the drive spun up that fast. I'd probably go with a 4200RPM HDD for a laptop if it's an option.

Help, my PC with Windows 10 won't shut down properly

Since upgrading to Windows 10 my computer won't shut down properly. I use the menu button shutdown and the screen goes blank, but the system does not fully shut down. The only way to get it to shut down is to hold the physical power button down till it shuts down. Any suggestions?
