Ok I'm extracting a 4.35GB archive using win 7 64 bit and its taking ages.

I have enable multithreading in winrar options

and I am getting very low cpu usuage

whats wrong?


Is my Raid 0 system drive at fault?

Extracting doesn't use much (if any) CPU because there's nothing for the CPU to do.

It's likely your archive was fragmented across the drive during download hence the long extraction time.
 
If you have 2 drives (physical, not partitions on the same HDD) put the compressed file on one and extract to the other.
 
is using an SSD and reading and writing at the same time a problem?

Say I have a 4GB MKV video on my SSD drive and I want to convert it to a MPG on the same drive is this a problem when using an SSD?

I may get an SSD at the end of the month.

This RAID 0 as a system drive is bottlenecking my system I think.

That would cause lots of writes to the SSD. I use HDD to HDD for ripping and re-encoding.

I've used AudioConvertor to convert DTS to AC3 on a bunch of MKVs so I can play them on my WDTV. I had to move the system TMP & TEMP folders onto a HDD as it was writing 5-10GBs to temp folders for each file I converted.

How is lots of writes really a problem? SSD's have wear leveling, by the time each cell in an SSD has worn out you likely would have replaced it with a larger capacity SSD. I don't see the point in getting an SSD if you're going to use a mechanical HDD for stuff that the SSD should excel at for fear of wearing it out.
 
best way to extract files is to do it from one physical drive to another

I prefer 7zip, you can open two window panes and it extracts directly instead of copying to a temp location first
 
Doesn't WinRar extract directly then?

I extracted 11.9GB the other day in 6 minutes. That's with a Q6600 and it was a 1TB WD GreenPower drive.

Performance when extracting to another drive though is so much better. Though I don't do it often. WinRar's "right-click->Extract Here" shell extension is just too damn convenient.

That's an interesting opinion. What SSD are you using?:confused:
 
I think the bootle neck is write performance on the Raid 0 system drive

I just unrar-ed the same file and on works PC C2D 6300 running stock and cpu was 25% and it actually did it faster than my 920 @ 4ghz!
 
NathanE, I don't know, I assume the right click menu does it directly, it's been a while since I've used winrar
 
What WinRar should do is read in like 100-300MB of the RAR's... then decompress in-memory and write out to the destination. Repeat process.

Surely a strategy like this would majorly reduce disk head movements and speed up the whole process?

Obviously you'd need a fair chunk of free RAM but most PC's do these days.
 
Or just use a download client that does auto repair/extract during download :p

Grabit on newsgroups for example will extract every x number of files while the rest are downloaded so by the time it's 100% downloaded you just open the folder and BAM, your extracted file is waiting to be dealt with.
