I’ve bought Sandisk Extreme 64GB CZ80 from amazon.com.
After connecting it to my iMac, i’ve formatted it with HFS.
Now i have following problem - read speed are very fast (>200mb/s), but write speed are between 1-3mb/s.
I also tried to connect it to my macbook - write speed varies between 5-8mb/s.
How to solve this problem?
