-So I've installed parallel port Iomega Zip, no problem (once
-I'd run depmod), and now I'd like to hear some opinions about
-the speed. So: what kind od read/write speed I should expect (in
With the standard parallel port driver expect speeds along the lines of
On the Enhanced Parallel Port (EPP) with the Curtin driver I've seen
a 10x improvment (10MB/min) using the same machine, ZIP drive, and port.
Just changed the driver.
I have a SCSI ZIP. Generally I get between 20 and 25 x the performance of
the standard parallel ZIP drive (i.e. 24-25 Mbytes/minute transfer rate)
How much is it different for parallel port vs. SCSI
-model ? Any truth in "20 x faster than a floppy" label on the
-disk box ?
It's faster than a floppy. Snails are faster than floppies.
- Does it differ for various parallel ports ?
Yup. EPP ports give a definite advantage. Enough of one that I'm wondering
if a EPP parallel port PCMCIA card exists so that I can use it when I
get around to buying a parallel port ZIP drive.
- Under Linux vs. DOS/Windows ?
My understanding is that DOS/Windows has a highly optimized EPP driver than
can approach the SCSI ZIP speeds.
- (Haven't tried the latter.) Under Linux,
-mounted as ext2fs vs. DOS fs ?
Only the filesystem speed matters then. ext2 is much faster than DOS FAT.
- Any opinions about reliability ?
Never had one fail. Doesn't really help though.
