OSX 10.8.4 MBP: Expresscard/34 & SXS very slow transfer speed (3.4MB/s)
Hello,
I’ve got an mid 2009 Macbook Pro with an expresscard/34 slot. When transfering data from a Sony SBS64G1A the read speed is at around 3.4MB/s. The card has a max read speed of 1.2Gb/s, so assuming expresscard can deliver, it should be around 150MB/s.
I’ve installed the SXS driver and I’m transferring through finder (rather than that Sony application).
Can someone tell me if this normal? If there is a solution to speed it up?
Thanks in advance, Maarten

Back when I initially installed the SXS package it was up to speed. Somewhere along the way it got very slow. Maybe with an OSX update another UDF driver got installed. Anyways, I had udf: Version: 2.3 (Last Modified: 6/25/12 8:03 AM) installed. Now I’ve installed from the sony website: sxsudf_fs: Version: 2.0.0d007 (Last Modified: 5/29/12 10:36 AM). That has brought it back to speed at 160-169MB/s
