(such as wear leveling and garbage collection) which result in write operations. That’s why it’s also
best to perform an “eject” before removing any flash based memory (including USB drives and
SSDs).
Best Practices
With this background in SSD power requirements, we offer the following best practices in handling
SSDs:
SSDs in Gemini 4:4:4
Ensure the power supply (battery, AC or power tap off the camera) can supply at least 20 watts
to the Gemini (to support both average and instantaneous power). In particular do not use “Y”
cables off the +12V power tap on the ALEXA. Do no attempt to power multiple devices
( LCD monitor) from this power source.
Do not run your batteries down to zero charge, stop at 15% remaining capacity to enable
adequate power to record and close files.
If you do lose power while recording, remove the SSD’s and use other SSD’s for further
recording. If you repower the camera and Gemini 4:4:4, then record on the same SSD’s, the
footage recorded after the power failure will be inaccessible.
NEVER remove an SSD while recording or playing video. This can cause catastrophic failure of
the drive and resultant lost footage.
If you accidentally cause a drive failure, you may be able to recover the drive by removing the
video cables to the Gemini 4:4:4, removing other SSD’s, then inserting the SSD in a (powered)
Gemini and waiting upwards of 20 minutes for the drive to rebuild itself.
After 20 minutes, power off the Gemini 4:4:4, wait 5 seconds, then power it on again. If the
recovery was successful, then the SSD LED will turn green after about 10 seconds or so. We
may also be able to recover the files. Please contact tech support for more details.
If an SSD does recover, please sequester this drive and do not record any additional video to
this drive. We may be able to recover the last “take” if no additional recording is added to the
card. Again, please contact tech support for additional guidance.
When prompted, please perform SSD Update to version xxx (takes 30 seconds). This greatly
impacts reliability and performance of the SSDS.
