Maximize battery life flash by using the Scriptures of sector size file. USB and SD card storage limits Cap

I use the sbRIO-9636 with 512 MB of non-volatile storage (Flash I presume?).  I'm not find the size of the sector in the Spec Docs, I found it, and Measurement & Automation Explorer does not display it no more, and I can't find one physical property of RT to make it.  I built a utility 'RIO leader Writer"for the text written to the buffer until the sector size is full or until the file is closed using the VI, but it would be useful to know the sector size.  For now, I'll assume 32 KB as I read the 9606 uses 16 k with its 256 MB drive.

I have attached the utility (a single LV 2012 (VI) in case someone else would be useful.  I promise you there better performance or memory efficient, but its purpose was to save the Flash of my application, which supports the recording of data CAN (1000 + packets/sec) to the file, and it does that very well.  I continued to save the CAN data without it, with each written separately CAN package (~ 40 characters / record log, or ~ 820 written by sector of 32 KB), I probably would have started to lose areas in the next few weeks was not that of wear levelling - maybe even with wear leveling.  With that, life shouldn't be a problem (although the ability remains one, I can switch to USB storage if it is).

Come to think of it, this can help with all the data being quickly to any player, as all readers use sectors (or blocks of sectors), assuming that you can sacrifice the RAM requirements to register your system hard disk (or to).

Storage issues more:  What is the limit of the capacity of the SD and USB function storage on the sbRIO-9636 map?  The specification mentions support SDHC, but does not say specifically THAT SDXC is not supported.  It does support the monstrously huge SDXC cards or the max for SDHC (32 GB)?  In addition, with SD and USB storage, is size of block review?  LabVIEW has a property, I can read for all this that I don't see?

Thank you!

Hi Erik,

I was wrong, we have a LabVIEW function that will find the size of area for a specific drive, it's the Get Volume Info.vi (link). You can run this VI and the flash drive on the sbRIO to find the minimum size of sector for reference entries.

Regarding external drives to the USB port, I think you are right in your assumption about the limits of FAT16 and FAT32. Keep in mind there are also limits on file size of 2 GB or 3 GB of maximum file size.

Most of the USB-to-IDE adapters works for the sbRIO (or cRIO), but USB-to-SATA is not supported to work on sbRIO. You can always try to use a SATA-USB HARD drive, but it might not work.
