Note: This table should be helpful, but cannot be totally relied upon for a number of reasons - rounding errors, inconsistent conversion of syslog number, grabbing an interim speed instead of final average, user vs system started parity check, etc. Both the old and new entries may be helpful to different users, and it is even more helpful when comparing the two entries, in showing how the changes have affected the parity check speed. If you have upgraded your system and want to update your entry here, please add a new entry immediately below your previous entry, with the updated numbers.

If you would like to estimate what your parity check speed should be, please see 'Calculating parity check speeds'. Others using IDE mode have not seen the discrepancies. Multiple users have noted discrepancies in parity check and transfer speeds when NCQ is enabled if AHCI mode is used in the BIOS. Two new columns were added on 4/13/09 to reflect the UnRAID version and if NCQ has been disabled or not. Since the cache drive is not figured into the parity check it was decided not to 'include' it as a 'real' drive but to show that it did exist by adding the '(1).' If you system has a cache drive please specify it with a '(1)' behind the total number.

The Drive Count column is the total number of drives you have in your system, not including cache drive. Add your Parity Check speeds here, to help others judge if their system is 'performing well'
