Default what unit allocation size when formatting HDD for digital audio library?

For a Windows 7 64-bit OS computer. This is not for a raid of any kind.
How should I set allocation unit size for a 2 TB harddrive to use for video and audio library when formatting a new harddrive?

the audio library will be FLAC files and also MP3s made from them. (from 500 audio CDs).

512 bytes
1024 bytes
2048 bytes
4096 bytes (4K)

also regarding partitions
should I just stick with the entire drive as 1 partition?

My external HDD is 1TB, one partition, and formatted to NTFS.

It is one of the options when you are formatting a hard drive.

Well, I don't know what mine would be then. When I bought it, I simply did a quick format to NTFS....I don't recall if I had the option to change the allocation size or if so, what I changed it to....sorry!

The larger the block size, the more wasted space when the hard drive is formatted. However, at 2TB, the correlation is so small that it should be an after thought. Smaller block sizes are more efficient, however, performance is marginally slower but shouldn't put an impact on it. I suggest to use the default settings so there will be less headaches.

Use the default size, which (IIRC) is 4k. The smaller size gives you less wasted space per file, while the larger gives better performance. A music library consists of relatively large files, so you'll have relatively few of them on the disk compared to, say, a disk full of 2k text files, so there's less space to gain . If you knew there would be mostly very small files on the disk then you might consider using a smaller allocation unit size.
