Decompressing (Winrar) CPU Or HDD?

[shadow007]

I extract big rars using winrar and I am extracting like crazy. I currently don't have a PC desktop and am using my laptop but I see my cpu is not being used that much when am extracting? so am thinking it must be the hard drive? The reason I need to know this is I will be building my PC in a months time and will be doing allot of decompressing using winrar and if a good cpu is needed then my choose would be a 6 core cpu.

pretty sure winrar/winzip is CPU heavy? my cpu maxs out unzipping large files

A little testing for you,

[email protected],

WinRAR benchmark = 6390 KB/s
Compressing a 9.84GB HD movie - 7 mins, 36sec

i7 3930K (only Turboboost ON, so 3.8GHz max)

WinRAR benchmark = 12,449 KB/s
Compressing the same 9.84Gb movie = 4mins 59 secs

Same speed RAM (obviously dual vs quad) and a Intel SSD in both setups.

Decompressing will be bottlenecked by your HD read/write speed. Ideally you want to be extracting files to a second drive.

Mechanical to itself ( c: to c: ) - 20-50mb/s
Mechanical to Mechanical ( c: to d: ) - 70-130mb/s
Mechanical to SSD - 70-130mb/s
SSD to SSD - 150-500mb/s

Mechanical to itself ( c: to c: ) - 20-50mb/s
Mechanical to Mechanical ( c: to d: ) - 70-130mb/s
Mechanical to SSD - 70-130mb/s
SSD to SSD - 150-500mb/s

Will it help if you have SSD's in raid 0 ? seeing above seems SSD to SSD is the best so am guessing SSD in raid 0 would be better?

What about SSD to Mechanical ?
