Compact flash write times slow?

DoogUK · 20 April 2009, 02:28

is it me or are the write times on the internal compact flash mods realy slow.....on either on my 1200's and even in winuae.

Normal. CF are slow to write. Slower than a normal HD, not something like pushing a concrete block over cold molasses.

Blazing fast to read.

Check card's speed rating. <whatever>X = same as CDROM speed rates, 1x=150K/s etc.. (all modern CF cards are much faster at writing than Amiga's crap PIO0 IDE..)

Its read times are nice and quick......but write times are too slow even in winuae.

I'm going to revert back to 2.5" ide HD and use the CF as a slave for file transfers in my 1200T.

Get a better card, it is either bad, has really slow rating or does not like Amiga's IDE. For example 66x card can write more than 7M/s. (check any CF digital camera review for speed tests

)

I bought 2 of the generic 4gb ones that were shown on a thread on here and they are both slow.....just tried a canon 1 gb from my digital camera and thats the same.

As far as i can make out the generic ones are x2.

I'll buy a 133x.....give that a shot.

My A1200 + 68060 + Blizzard SCSI + Acard + IDE->CF adapter + Sandisk Extreme III 8G CF card.

Filesystem read/write speed is about 6M/s (diskspeed test).
Raw read/write speed about 7.5M/s (close to practical SCSI-2 max speed)

Don't buy generic cheap&crappy cards

Ahhh but i was advised they were highly compatible...which was the biggest hurdle to overcome at first.

Cheap&crap ones most likely have random internal components from cheapest supplier at that time
