Any devices allow to transfer fixed amount of bytes per one request.
SATA allows only 100KB = 200 sectors to read/write from/to device per one request.
Can I change this value(), for example to 1M oder ....

maybe :
request_queue_t *q;
q = bdev_get_queue(bdev);
q->max_sectors = XXXXX;

I am unsafe .... ?

thanks...
