A standard USB what? I shall assume you mean a block storage device, such as a hard drive. Sub directive? I shall assume you mean subdirectories. The answer is, that depends on the file system. Modern FAT variants, NTFS, Linux's file system, currently ext4, and others all allow subirectories. Early versions of FAT did not, but I doubt you will find any of those in the wild these days. Another question is, how deep can you nest subdirectories? Again, that depends on the file system. I doubt any modern file system has any limit (other than room available) as subdirectories are often stored as linked lists. > > I was doing some stress testing, and some sub directives had very long > write latency's. (All less than 4GB.) I doubt the problem is subdirectories. More likely something totally extraneous to your tests was causing problems. I would eliminate that possibility by running such tests in single user mode. -- Does anybody read signatures any more? https://charlescurley.com https://charlescurley.com/blog/
