Same technology ? Interface ?

What do you mean by "erasing" ?
 * removing the partition table
 * overwriting the first few sectors with "dd if=/dev/null of=/dev/.. "
 * formatting again the partiton
 * overwriting the whole drive ?

Writing the whole 3 TB drive would take a few hours (at 50 to 100 MB/s,
I let you compute), if I trust the raid5 synchronisation on partitions
of 2TB that I observed.

The three former method are rather quick and might not have too much
impact by the disk size. (at worst, a few extra superblock to be written
along the disk)
