Speed Test: Samsung EVO Plus mSDXC UHS-I 256GB
R130/W130
Product Number: MB-MC256KA (MB-MC256K written behind the Card)
MDT: 2023/10
PRV: 3.0
Highest CropMood speed reached for a 1 minute Clip (Peak Orange): 87 MB/s @ 2.8k/14bits
Highest CropMood speed reached for "Continuous" (Steady Green): 76.6 MB/s @ 2.8k/14bits
Highest CropMood speed reached for a 15 seconds clip (Red Speed): 88.9 MB/s @ 2.8k/14bits
240MHz / SDR104 (Benchmark is identical with SDR50)
Card has been formatted in camera (EOS M), moved to a Mac to copy the CropMood files, then back to the camera to make it bootable.
The testing method is outlined here: https://www.magiclantern.fm/forum/index.php?topic=25841.msg245694#msg245694
This time, I filled up the whole card's capacity with tests. This gave me more data: (The cam stops recording by itself)
30 Seconds: 87.6 MB/a
23 Seconds: 88.2 MB/s
18 Seconds: 88.6 MB/s
10 Seconds: 91 MB/s
The card is not as consistent as the Lexars in the red zone, but is very consistent in the Orange and Green Zones.
The performance is on par with the Sandisk Extreme Pro 256GB R200/W140, and costs 30% less even at regular price.
No Safe Mode triggers, no throttling, only a few sporadic "Frame Order" error messages (4 messages out of 90+ clips recorded), where the recording stops early.
Regarding the Benchmark:
The benchmark runs between 8-10 seconds and the number it gives is close to the 10 seconds results I got in the test. In this area, there is a lot of variability, except for the most expensive cards.
As discussed previously, a 1-2 MB/s difference can double the possible recording time at the higher end, and add up to several minutes in the low orange zone.
Most compatible "Pro" cards can perform reliably in the Green Zone (76-78 MB/s), but around this data rate, 1x3 4.4k/12bit and 1:1 2.5k/12bit are the highest settings where you'll get reliable recordings.
So, the most interesting zone to test is the Orange zone, where the cam can record continuously for 1 minute +. This is where the door opens to the highest resolutions.
1 minute is plenty to record about everything I see posted as examples on the facebook group...
Very few people will go through the trouble of testing the cards manually, and most people return the cards immediately if those don't work as expected. This makes it hard to know what can be done with a particular card, and those vary, sometimes substantially, between revisions.
So it would be nice if the Benchmark could test for SUSTAINED speeds for a given length of time,
which would make it a lot more useful and make it easier to build a reliable Card Database, as reporting would be simplified.
