Memory - Ocean Instruments SoundTrap ST640 User Manual

2.3 Memory

The SoundTrap ST600 series have capacity for up to 4 microSD cards.
Important things to note about memory:
1. You should only use the recommended memory cards – Samsung Evo MicroSD (up to
512GB). All Evo card types are fine, including Evo, Evo plus, Evo Select. Counterfeits of these
cards exist, so only source from reputable suppliers. Using other card types or counterfeits
may result in performance issues such as increased power consumption, sampling gaps or
unreliable recording.
2. The cards are used in the sequence 4->3->2->1 where 1 is the top-most card. Any full or
missing cards will be skipped.
3. It is critical that each card is formatted prior to each deployment. This can only be done in
the SoundTrap recorder using the 'Delete All Files' option. This must be done for each card
individually.
4. SoundTrap uses a custom file system to maximise performance and reliability. This means
the cards can only be read with the 'SoundTrap Card Reader' application supplied with the
SoundTrap Host software. When inserting the memory cards into a PC you may receive a
message like "Drive is not formatted, do you want to format it now?". Agreeing to this will
result in loss of data. Instead select 'No thanks' and run the SoundTrap card reader
software.
