From the sa(4) man page:
FILES
/dev/[n][e]sa[0-9] general form:
/dev/sa0 Rewind on close
/dev/nsa0 No rewind on close
/dev/esa0 Eject on close (if capable)
/dev/sa0.ctl Control mode device (to examine state while another
program is accessing the device, e.g.).
BUGS
[...]
Fine grained density and compression mode support that is bound to spe-
cific device names needs to be added.

Devices are documented in secion 4 of the man pages. Generally there
will be a man page for pretty much any device under /dev: just strip
off any unit numbers or other extra characters. Sometimes the man
page is listed under the kernel option required to enable it.
eg:
/dev/zero --> zero(4)
/dev/sa0 --> sa(4)
/dev/nsa0 --> sa(4)
/dev/da0s1a --> da(4)
/dev/dsp0.0 --> snd(4) a.k.a. pcm(4)
Cheers,
Matthew
