RAID1 VS RAID5

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hello,
I would like to buy new SCSI hard disk to be used with lsi 160
controller in 32 bit pci.

I can choose:

- RAID5 of three Maxtor Atlas 10K II 9gb
- RAID1 of two   Maxtro Atlas 10K III 18gb

My problem is: I have seen that RAID1 code does not interleave reads so
it does not improve performance very much putting two hard disks.

Is there a patch to change raid1 behaviour?

In linux 2.6.0 is it better?

Thanks in advance for any reply.
