Can we omit ‘rated speed’ seems like a lot of people will quote burst speeds which are often arbitrary speeds the card manufacturer claims. For our purposes class is more useful as it’s indicative of minimum sequential write

Class 10, U1= 10 MB/s
U3, V30 = 30 MB/s
etc

Unless you want to use it as a descriptive identifier for the card- ‘Lexar 2000x’ , ‘Sandisk extreme plus 150 MB/s’ etc

Also model number and if known, country of origin may be useful. I have two sandisk cards purchased recently, one was made in China and is ‘extreme’ and is pn SDSDX-V5..... The other is made in Taiwan and is ’extreme plus’ pn SDSDX-W5. Despite one being labeled plus every rating on them are identical.

  Also should we list test duration? I’ve had some tests go for over four hours and then crap out

Dealer name and even purchase date would be most useful as well.

If got through Amazon, it’s also important to know wether it’s been sold and fulfilled by Amazon or it came from a third party seller.

There seem to be more fake cards than real ones nowadays.

for sure. first thing i do with any card is write it front to back with h2testw to make sure it has full speed *and* capacity. unscrupulous sellers have found ways in teh past to make card capacity look larger than the actual writable area (like sell you a "128GB" card thats really only 32GB)

apart from that, not only are there fakes, there is malware in some cards. check out this dated, but fascinating, article.

https://www.bunniestudios.com/blog/?p=3554


im still looking for the old-school disk benchmark software that would write and graph a disk across its whole surface (premise being inner and outer transfer rates on spinning disks are vastly different)... but i feel this could be useful on making sure a card can write to full speed all the way up to the point of full

first card I tested that could sustain the mixpre6's max write rate. Actually bought this little guy for my roland R-07 which is limited to 32GB SDHC but its the best so far. Will check into larger sizes in the PRO series

Mix-Pre type: 6, FW 3.03, preroll off
Manufacturer: Sandisk
Model: "100 MB/s Extreme Pro microsdhc, $14 purchased 7/2019
(https://www.amazon.com/gp/product/B06XYHN68L)
Card Size: 32GB (29GB usable)
Class: class 10/ U3 / V-30 /A1
Part#:SDSQXCG-032G
Serial #:
Tested speed (h2testw): Writing speed: 49.5 MByte/s, Reading speed: 70.2 MByte/s


Recording Format (Bit Depth/Sample Rate):24/192
Number of Channels: 8 (6 iso+mixdown)
Phantom (On/Off): 4 channels on
Result: PASSED. Filled entire card, 1:55:00, three times with no errors.
Notes: first time was low level formatted on computer, then formatted in mixpre. Quick formatted in mixpre for runs 2 and 3
Powered by 4 fully charged Powerex Precharged AAs, starting voltage 1.37V per cell. Battery indicator started blinking red somewhere between 1:57:00 and 2:04:00 (i walked away so not sure when it hit red exactly), at which point i switched to usb-c battery. Third run was done with powerex pro (non-LSD) and was blinking red after 1:59:00 and shut itself down 4 minutes later, so more or less equivalent to the powerex precharged LSDs

I formatted the card in the MP6 and then recorded until card was full without any problem what so ever. :)

Note:
The 32 and 64 GB have a lower rated write speed and I have not tested those!

Re: Mix-Pre 3/6 SD Memory Cards (What works and what doesn't?)
« Reply #14 on: September 07, 2019, 02:40:26 AM »
I got a new USB3 UHS-II compliant card reader as all of the card measurements i was taking with my older Toshiba Portege's built-in PCI SD card reader ("Ricoh PCIe SDXC/MMC Host Controller") seemed to top out around 40MB/sec write and 60 MB/sec read

new reader:
https://www.amazon.com/gp/product/B012PSAEDC

I still have some of the cards tested above, will rerun. where you see "Lexar SR2" in test note,  thats the reader im using.

I have a slew of these Portege R83x/R93x laptops for home and work use (like my audio gear, im a brand loyalist and have been using toshiba for 2 decades). cards at home that were running 40/60 do 50/70 on what i believe is the same PCI-e controller and driver, will investigate

ive also seen differences of 10% on the Lexar SR2 depending on the USB3 controller and driver to which i connect it

Point being, i suppose, is there are vast differences in how different hardware and software installations handle the same card (which is the point of this thread, i suppose)

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
