Hi,

I just tried CRCD on my dual PII/2GHz, NT, Raid-5, LTO-1. Almost unmeasurable performance impact, neither on disks nor on tapes. But be cautious - IT DEPENDS - even on the same mache the results could be completely different if CPU were busy with another operations. Once your CPU&CRCD will be too slow to fill/empty LTO tape buffer timely, you can expect disastreous performance breakdown. Using Raid10 instead of RAID5 could deliver different results as well... regards Juraj
