IFD 2.62 - Slow image to RAID 0

Post by highend »

Hello,

yes, it's an older version atm. If there are any chances, that an actual one will be faster, I'll burn a new disc ;)

Z77MA-G45 Mainboard, 8GB Ram, Intel i5-3570k
Boot device (and the device from wich the image is taken): Samsung 830 SSD 128GB on SATA6 Port
The one and only partition is correctly aligned.
Storage device(s) (and the device to which the image is written): 2 x WD 2TB EARX drives on SATA3 Ports
The WD drives are configured as a RAID 0 with approx. 3,7 TB formatted space.

IFD: BIOS (Direct) is used as well as File (Direct).

My problem: Creating an image from the SSD to a folder on the RAID 0 is way to slow. It takes about 10 minutes for about 8GB.
That's a transfer rate of about 14MB / Second^^

The SSD has a read speed of (max.) over 500MB / sec and the two drives in a RAID 0 have a write speed of over 200MB / sec.

Any suggestions how to improve IFD's performance? Do I have to upgrade to the current version because there been major improvements in terms of speed?

BIOS (direct) will use BIOS on RAID so there is no difference. The problem
is your BIOS on the RAID card is using slow IO. You'll have to use Image
for Linux or Image for Windows (or a RAID card that uses fast IO like
promise or areca)

Thanks for the clarification.

Creating an image with IFW is much faster than with IFL, e.g.:
7,4 GB Win7 Installation
Time to complete with IFW: 70 seconds
Time to complete with IFL: 130 seconds

Is there any reason why IFL delivers only half the performance?

Restoring the same image back is at least in the same range.
IFW: 25 seconds
IFL: 33 seconds
Nothing to complain there :)

caching for one , you could mount the file system in linux and may get a
boost using the file (os) option.

Mounting the RAID and using File(OS) takes the time down from 130 to 110 seconds.
IFW is still far ahead with 70 seconds.

I'll probably use Image for Windows and automate the process with a simple batch file to get the maximum speed.
Did I already say I love all the Image for ... products because of their extensive automating capabilities? :)
