Samsung Pro Plus SD     for EOS M

Ok, got the Samsung Pro Plus sd card today (not the micro-sd version)

It's slightly better thatn evo select micro sd version but not by much.

160Mhz   writes at 54.8MB/s
192Mhz   writes at 59.7MB/s
240Mhz   writes at 19.7MB/s

so 192Mhz is the best fit. And since it's marked as 'professional', hopefully it will be more durable than evo select version.

New to the forum, here to post some findings. Just got my first Eos M and I have some sd/micro sd cards laying around, before I buy a new one I thought I would test them out first.

Samsung EVO select microsd 128GB,   160Mhz gives best results @ 54.5MB/s, which is enough for 1080p at 14bit, which is the only mode I need, this card runs about $20 on amazon.
Samsung EVO select microsd 256GB,   192Mhz gives best results @ 56MB/s, which is enough for 1080p at 14bit, this card currently sells at $35 on amazon, I got it when it was on sale at $25.
sandisk extreme Pro 95MB/s 32Gb,      192Mhz gives best results @ 44MB/s, just about barely enough for 1080p at 14bit.
SanDisk Ultra 64GB MicroSDXC, this card is a no no, it barely goes above 20MB/s, so not enough for magic lantern.
Patriot LX Series 64GB, slightly better than Sandisk Ultra, goes to about 28MB/s, still not enough for magic lantern.

So shooting at 1080p 16:9 at 14bit, you are gonna need at least 41 MB/S writing speed. A 64GB card is gonna give you around 20minutes of footage, 128GB 40min, 256GB 80min and so on so forth. Based on my personal experience, a 8-10 hours shooting day(story based short film), I usually get about 60-75 mins of actual footage on camera. So for me, 256GB is the minimum.

So if you are like me looking for a cheaper alternatives to the much praised but more expensive SanDisk Extreme PRO, samsung evo select is a pretty good contender, they are not as fast as Sandisk extreme pro, but  good enough for what I need.


Currently I'm waiting for a 256GB Samsung pro plus full size SD card to be delivered,  I got it when the price is marked down to $30 for 256GB size, not sure it's temporary or permanent. It's supposedly designed for 'professional' use so I expect it to be more durable and writes fast than the consumer grade EVO select. I will report back when I receive it.
