Removed scanning for stride - Adds complexity with questionable benefit - Can be added as an optimization later Fixed handling around device boundaries and where lookahead may not be a factor of the device size (consider small devices with only a few blocks) Added support for configuration with optional dynamic memory as found in the caching configuration
