List of good (and bad) SD cards
« on: July 01, 2017, 12:54:34 PM »
Let's make a list of known working and not working SD cards for Chronos, since some people seem to be having problems with video skipping on certain cards.

I have had very good luck with The following cards:

Lexar Professional 633x UHS-I

SanDisk Ultra 32GB microSDHC UHS-I (SDSQUNC-032G-GN6MA) (These were included with the promo cameras sent out before the Kickstarter)

That is the same card I use for all the Gopro's and drones I have. When you have a subject you feel is going to be important you can make it a sticky so it will always stay at the top.
You were saying something about good and bad USB sticks also.
What is the preferred format the camera likes. FAT or NTFS?

I have been using a "SanDisk Ultra Fit 128GB USB 3.0 Flash Drive (SDCZ43-128G-G46)" almost exclusively and out of a hundred recording I have only had a couple write failures but they may have been related to what I was doing (still trying to figure d a way to replicate the problem). Otherwise it's very fast and the slim form factor makes it very convenient.

David,  Which Lexar cards do you recommend? The link you posted has various sizes.

I've only used the 32GB size from that link. The others would likely be fine but that's the one I've tested.

Can the files be transferred to a computer Via USB without the need of an SD card? Or is the SD card required?

Currently you have to remove the SD card from the camera in order to transfer the files.

In the future, the camera is planned to be able to provide a USB Ethernet interface through the USB OTG port, acting as a USB device. This would create an virtual NIC device on a PC that communicates with the camera directly, which is convenient in many ways. We are thinking about the possibility of exposing the filesystems of the attached disks of the over this network interface, but I don't believe we have made any concrete plans just yet. I'd imagine that SFTP, rsync, HTTP, FTP, etc. could all be used in theory.

I couldn't get the Lexar card, so I tried this one:

https://www.amazon.de/SanDisk-Extreme-Speicherkarte-90-MB-Class/dp/B01M0I3H4Q/ref=sr_1_3?ie=UTF8&qid=1505287640&sr=8-3&keywords=sandisk+64gb+sd

I haven't set up the camera yet, so I couldn't test it, but I hope it's OK.

Update:

The above SD card (SanDisk Extreme 64GB 90MB/s) seems to work fine. During my tests I had no dropped frames or skipped out points or such. Works fine, and is way better to get, at least over here in Germany.

I had a Samsung micro-SD card laying around from a dash cam I no longer use.  It is 128 GB, so FAT32 isn't an option.  I had the card formatted exFAT, and I can see it on both my Mac laptop and PC desktop.  I tried to use it in the Chronos today, and the camera refused to recognize the card at all (wouldn't even show up in the storage device list).  Thankfully, I had an extra 8 GB Kingston Class 10 card laying around (that I later found out was formatted FAT16 with a 60 MB partition, causing other problems described in another thread). 

Has anybody been able to format a 64 or 128 GB card in a manner when the Chronos will recognize it?  If so, how?

I used a third party software to format the card in FAT32 (it worked fine on a Lexar 633x 64GB for reference), I can't remember the name but as soon as I go home I'll post it ;)

Edit: I used EaseUS Partition Master on windows 7.

Here is a free software that ONLY formats in FAT32.

Formatted my 128g SDXC perfectly.

I tried this one and it didn't work for me.
