Ubuntu 10.10 RAID5 NAS Performance

[sammynl]

Would like to share with the DIY folks that I've installed Ubuntu Server 10.10 X64 on a box and the performance is great. This Ubuntu version is much faster than 9.xx versions.

When performing a data restore to the NAS (5*1 TB disks in the Linux RAID array with 256k chuncksize) from a Windows7 X64 client using Robocopy, in total 376 GB was written to the NAS in 1 hour and 7 minutes, that is 95.1 MB/second! I think that is an impressive write-speed considering the amount of data and the large number of 13000+ files.

sammynl,

Thanks for your sharing. I am doing research for build a low power consumption but fast NAS.

Do you have chance to test the read/write performance on a single HDD rather than raid 5?

Also, I am thinking about use mini-ATX+ATOM cpu to build the NAS, any suggestion? I will probably put 4~6 HDD on it

Thanks
