Mix-Pre 3/6 SD Memory Cards (What works and what doesn't?)
jerryfreak:
I've received justme's 128GB integral card mentioned above
while i no longer have my mixpre, i did some benchmarks on this. Anybody in the USA want to volunteer to test this card, we can pass it around
would be best if testers can commit to doing a minimum of two full write cycles at 8 channels of 24/192 (7.5 hrs per test). And even better if some people with the mixpre-ii or mixpre10 can test at even higher bitrates/hannel count
my benchmarks:
full card sequential write test with H2testw v1.4 on Ricoh PCIe SDXC/MMC Host Controller:
Writing speed: 47.2 MByte/s
Reading speed: 71.8 MByte/s
full card sequential write test with H2testw v1.4 on Lexar SR2 USB3:
Writing speed: 66.9 MByte/s
Reading speed: 79.4 MByte/s

from GLouie, 3 cycles filling up the card, total test time: 8.5 hrs:
MixPre10II firmware 7.11
32b float-192kHz
recorded 8 ISOs
3 passes until disk full message, no error messages
Sandisk Extreme 64GB SDXC - UHS-1
Model SDSDXV6-064G-GNCIN
150MB/s
serial#BN19274835730
Made in Taiwan
Black Magic Designs Disk Speed Test v3.3
2017 iMac, built-in card reader
Write: varies, around 58MB/s
Read: varies, around 90MB/s
Vendor unknown, these were a gift, but I gave the B&H link. Curiously, out of 3 cards, 2 were made in Taiwan and 1 was Malaysia.
This card is on the Sound Devices tested media list of Jan. 15, 2021.

Adding the mentioned updated list from Sound Devices Jan 15, 2021 for reference.
