I would like to test out the array's performance, I typically i/o large files (100MiB-100GiB) but when creating the array I left the chunk size alone and let mkfs.ext4 choose default settings (no special chunking or striping) Some of you are gurus who might be able to point me in the right direction for benchmarking and creating a proper array for my purposes. Thanks a ton for making linux raid so incredibly versatile and awesome! -- Andrew Dunn http://agdunn.net
