What MAY hurt, also for large writes, are the meta-data operations while writing the file. (e.g. the file-size changes, journaling ...)

But i haven't tested that and can't say for sure how much that hurts.

It hurts a lot. On my 1TB EARS when i was benchmarking unaligned partitions, untarring a linux kernel for example took ages. (tar output finished quickly but then you had to wait a long time till the shell prompt returns)

With aligned partition, performance is normal.

Extracting a linux tarball creates lots of very small files, so it is expected to perform very badly on unaligned partitions. But I suppose that copying the tarball itself to the disk could be only slightly slower than normal.
