The offset layout with a sufficiently large chunk size mostly does what you want. I recently set myself up with a 3 disk array like that and it pushes 500 MB/s using cheap, run of the mill 1 TB WD Blue drives. The offset layout gives slightly better performance than far ( as long as you use a sufficiently large chunk size ), and can be resized, unlike far. -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.17 (MingW32) Comment: Using GnuPG with Thunderbird - http://www.enigmail.net/ iQEcBAEBAgAGBQJS6rB2AAoJEI5FoCIzSKrwCgUH/2ObIJbpgipuSpf1JsTLyMJk zJnRkKISS6/1MiEtiBLRDYHhi2yL/B0S/J5jRSmgeLbAuM/q1cfF7BSOKfP52qUS frDIRO0AtWybE/8NNiLMe6dBG1Zkfn/P+atMQwGGfy5wMWAU1DcCzq/qlv+dVkP7 VHaGuEKm/A1ySzwxnKdPTbAfe1/wRrBDeQg4leZRP9nBLA+jDWmw3oGlHW/7Aeeb DCKKzU6+V1Hqrk8kmayh6A6D5Dp8AdPoMEj7q/I8edNX/Zp8NI/yH2wOrEkXI/xK kiE2E0kRHyTFQ2VxU0rGKzYzE4fcjtoaDdQxHhc58/5LkUE3PTDsTyBxKn0XsHU= =G5bT -----END PGP SIGNATURE----- -- To unsubscribe from this list: send the line "unsubscribe linux-raid" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
