LaCie drives set at HFS+ 64KB for FCP

Five years ago I corresponded with LaCie and they told me to reformat their drives at HFS+ 64kb for use with Final Cut Pro. I noted, as well, that when reformatting, using the utility CD Silverlining Pro that Lacie used to include with their external hard drives, that when you chose HFS+ 64kb the message came: "Faster manipulation of larger files or streaming video".

The new LaCies I'm buying no longer include the Silverlining Pro utility CD with their hard drives. What I've been able to do is keep using my existing version of Silverlining Pro to reformat at 64KB.

When LaCie told me to reformt at HFS+ 64KB they said that this was the feedback they'd received from Final Cut users. Can anyone confirm that this remains the preferred formating for FCP use, that 64KB is preferable for: "Faster manipulation of larger files or streaming video"?

While no longer including a version of Silverlining Pro with their hard drives, LaCie does say to go to the MAC utility if you want to reformat their drives in any special way. Unless I've missed it the MAC utility does not give a 64KB block allocation size option. Have things changed in the last few years such that this larger block allocation is no longer important?

Any thoughts out there?

Thanks.

Mac OS X Disk Utility does let you set the block size, but only for RAID sets.

From the Help file:

"To optimize storage performance of a RAID set, you can set the storage block size used by the disks in the set to match the size of data stored on the set. For example, a database might store small units of data, so a small block size might be best for the RAID set. A video processing application might require fast throughput of large amounts of data, so a larger block size might be best for the set."

Options are 16k, 32k, 64k, 128k and 256k blocks.

Regular HFS+ has a 4k block size.

Thanks for the reply. I guess the question that remains for me is should I continue to use my old version of Lacie's Silverlining Pro to reformat the disks I'm buying from LaCie at 64KB to use with FCP? Certainly once formatted that way they work fine. Conversely, since LaCie no longer provides Silverlining Pro and MAC apparently only allows formatting at block size 64KB when using disks in array (which as far as I can figure doesn't apply to me - I just have several firewire ports on my Apple and plug in several reformatted LaCies with a range of captured media into them), does this mean that using discs at their default block size of 4KB is actually fine for use with FCP?
