However, in testing I did several years ago, I was surprised to find no performance difference in using a blocksize of 1. I think the reason is that VFP internally reads and caches blocks of data and doesn't really read it from the file in blocksize increments.

Thanks.
Well, I thought there
might be a performance hit from other sources - like (perhaps) VFP taking longer to find unused space to save a memo field, or (again perhaps) a slightly greater probability of having to read data from more than one sector from disk. I understand that the operating system (or the disk system?) reads an entire sector at a time.
