Subject: Writing on raw device with software RAID 0 is slow
Date: Wed, 28 Feb 2001 15:58:11 +0100	[thread overview]
Message-ID: <3A9D1202.9A1C403E@gmx.de> (raw)

Hello,

Writing to an software RAID 0 containing 4 SCSI discs is very fast.
I get transfer rates of about 100 MBytes/s. The filesystem on the RAID
is ext2.

Writing to the same RAID directly (that means on the raw device without
a filesystem) works
but gives low transfer rates of about 31 MBytes/s.

Any explanation for that?

thanks and greetings,

Martin Rauh
