Probably! The problem is, that 146GB are not 146GB! If the capacity of the 10k drive is only one block smaler then the one of the 15k drives it will not work. It only works, if it's bigger ore the same size.
Thanks, I will check the spec's carefully. Performance issues are not a big concern.
i have same isues.my problem i have raid 5 10k drives.so i need to upgarade to 15k.so how to do?
