The issue with the SD cards is mainly the file system. The RealTracks and RealDrums have a huge number of files (100,000+), which means a huge file system. Windows drives and SSD use NTFS and they are designed expecting rapid access to huge numbers of files. SD cards we have tested in the past are much too slow in this regard. You can tell this by trying to copy an entire RealTracks folder using wu diss explorer and watch the slow speed as each file is copied and then an entry is added to the file system.
Band-in-a-Box accesses the drive during playback, and any drive slowness can result in audio glitches or silence (this is the case for any DAW, which is why fast drives are important.
The SD cards are getting better, and some use NTFS or can be formatted to do so. If anyone has had success with a new SD cards for use as a drive on a DAW or other digital audio program, please let me know.
Thank you very much, Peter, for these details that will surely interest many Band-in-a-Box users.
But I will probably not be the first to experience installing Realtracks on a high-speed SD card formatted in NTFS: if it is possible with my maxi tablet, I will rather choose to replace my 256 GB SSD with a 512 or 1000 GB SSD.
