Mix-Pre type: 6, 6, multiple firmwares (see below)
Manufacturer: SanDisk
Model: Extreme Pro SDXC UHS-I Card,  purchased 9/2019 from Amazon (directly), $39.99
https://www.amazon.com/gp/product/B07H9DVLBB

Model number: SDSDXXY-128G-GN4IN
Card Size: 128GB (119GB usable)
Country of Origin: China
Class: UHS-I, C10, U3, V30, 4K UHD
Serial #: BP1922852852G
Tested speed (h2testw on Lexar SR2): Writing speed: 60.9 MByte/s, Reading speed: 73.5 MByte/s
Recording Format (Bit Depth/Sample Rate):24/192 (except test 4 which was 24/96)
Available recording time on full card at stated bitrate: 7h31m
Number of Channels: 8 (6 iso+mixdown) (except test 4 which was 6 channels of iso only)
Phantom (On/Off): 4 channels on

Test #1 - FW 3.03, pre-roll off, quick-formatted on mixpre
Result: FAILED:Record Buffer Error after 3h55m, and subsequently after another 58 min of recording. test aborted shortly after due to low battery

Test #2 - FW 3.30, pre-roll off, slow-formatted on windows to exFat default (128kbyte allocation size)
Result: FAILED:Record Buffer Error after 2h02m, and subsequently after 31 mins, 14 mins, 24 mins, 14 mins, 11 mins, 6 mins...aborted test and ran h2testw on remaining space on card. it wrote the rest of the card out at 66.4 MB/sec

Test #3 - firmware 2.21, quick formatted on mix pre
Result: FAILED:"SD Warning - media is too slow" error after 2 minutes and subsequently after 66 min, and 56 min, test aborted

Test #4 - firmware 2.21, immediately after test #3, reduced bitrate to 6 channels at 24/96
Result: FAILED:"SD Warning - media is too slow" error after about 7 hours (card capacity 20 hrs in this case). Rest of recording sesh was a disaster, was only able to record 30+ minutes before failing 2 out of 15 times (file 487 and 488 were an auto-split), and those two longer tests also failed after 65 and 38 mionutes respectively. There is something about writing past 40% on cards that it doesnt seem to like

yes it seems most tests ive done on 3.03 fail after 1 hour, smaller cards have an advantage (the lone one i qualified was a 32GB)

i just downgraded to 2.21 and will be updating the test reports above as testing occurs (update: 2.21 appeared to be worse than 3.03)

Updated some previous tests after running them again with firmware 4.01.
No difference really. Same FAILED: "SD - Warning Record buffer error"

same so far. The one card i had that worked on 3.03 also works on 4.01. Every card that failed on 3.03 that i tested again (so far) on 4.01 also failed. Seems to be a lot of initial failures around the 2h30min- 2h40m range, then a ton of failures at less than 1h intervals after that . this would be at about the 35-40GB mark on the card. (obv the 32GB cards that are working for us never get there)

It doesnt appear that 4.01 actually solves the problem. Can you retest the Integral card on 4.01?

I’ve found that cards that perform poor on random writes will get hit with buffer error failures.

Running tests with CPDT on freshly formatted cards shown that cards with random writes around 1MB/s will fail in MixPre-6 within a few seconds only when running 8 channels in 24bit at 192kHz. Even if the cards do manages to write 30-40MB/s sequentially.

When cards reaches 3.5MB/s* at random writes they appear to be stable for 8ch recordings.
Some cards with random write in between 2-3.5 MB/s seems to be more down to for how long you record and some shear luck.

https://maxim-saplin.github.io/cpdt_results/?about=

* revised from 5MB/s
** revised from 3-4MB/s

I’ve found that cards that perform poor on random writes will get hit with buffer error failures.

Running tests with CPDT on freshly formatted cards shown that cards with random writes around 1MB/s will fail in MixPre-6 within a few seconds only. Even if they do manages to write 30-40MB/s sequentially. When running 8 channels in 24bit at 192kHz.
When cards reaches 5MB/s at random writes they appear to be stable for 8ch recordings.
Some cards with random write in between 3-4 seems to be more down to for how long you record and some shear luck.
