I think to actually have some real answers it is important that everyone provides more detailed info:
1. Exact model of the drive you use not just manufacturer and model name. Manufacturers would reuse the model name but can have multiple revisions with slightly different characteristics. Look for the full model number by the bar code on the packaging or on the drive itself. Serial number could also be useful to determine early vs later made variants.
2. Specify the size of the disk.
3. Is drive partitioned for music and Sentry? If so, what partition is first and what size are the partitions.
4. How long have you had the drive? Older drives would be more likely to be slow as they could have exhausted their spare/buffer cells and need to erase to write.
5. Use of "splitter", adapters, other remarks.
