Title: Tips to increase write speed
Post by: darkstarr on October 22, 2013, 01:17:07 AM
hey folks,

is there any tips on improving write speed to sd card?
currently my lexar pro 600x (rated at 45mb write speed) can only write at around  34.0mb/s

i've tried
global draw off
hacked no preview
memory hack on
extra hacks on

raw picture quality only
turning on camera in photo mode > load Raw Module only > Dont click me > switch to video mode

but i still get a max write speed of about 34mb/s
i guess its the card but is there anything else i can try?
(if any of my steps doesn't make sense or are outdated / no longer needed let me know lol)

and as far as the best bang for buck sd card for raw, so far the pick is Sandisk Extreme 45/45?

cheers guys

You're doing well getting 34mb/s I thought the sd card controller on the 600d would only go up to 21mb/s.

600D, where did you get that info?

Dig!c 4 bodies are liimited to 21, but 5(+) SD controllers are UHS-1, and can write faster.

Sounds perverse, I know, but his body HAS to be a newer model!

Edit: I've heard the Sandisk 95 is a tad (a relative term for sure) faster on Dig!c 4's, maybe it'll be faster for you (Dig!c >= 5).

ah sorry, forgot to mention, this is on a 6D, sd controller is rated at 50mb. some users are reporting constant write speeds of 39-40mb/s on that camera
