Re: [opensuse] Real World Sata-II disk-to-disk throughput? 77MB/sec is that about right?


Copying video between two Seagate ST31500341AS disks with ext3 filesystems I get about 77.8 MB/sec. Given they are supposed to be 300 MB/sec:

"Is the 77 MB/sec close to the real world max I should expect?"

Reports speeds similar to yours on a Sata-3G disc.

Reports 138 MB/s sustained on a Sata-6G disc.


I just tried copying 9GB (split about equally over twelve files) from a ST31500341AS (ext3) to ST3500418AS (ext4) and clocked 109 MB/s on average, maybe ext4 is a bit more efficient here.


Looks like your drives are doing quite all right.
