Data Overflow Storage in a Cronos PL-2?

Postby Ken.G » Wed Jul 16, 2008 2:19 pm

Is there any way in imcDevices to configure a device (a Cronos PL-2 for example) so that it can use both the Removable Disk (PCMCIA) and the Hard Disk for data storage? For example, say the Removable disk has been selected as the storage location in the “Global’ tab of the “Storage and display” screen and a 1GB CF card is inserted into the slot (with PCMCIA adapter), and a 1GB is also in the Hard Disk location. Would there be any way to configure the device so that when the Removable Disk 1GB is full, it would automatically start to fill up the 1GB Hard Disk (assuming the Hard Disk wasn’t used for any other purpose)?
Thanks.

Unfortunately, no. For systems equipped with two internal storage paths (nominally the "removeable" and "hard drive"), it is an either-or proposition.

However, keep in mind there are other mechanisms available to help you:
  • The formal hard disk can be up to 60 GB (currently), while the "soft" hard disk (i.e. CF slot in a system that also has a PCMCIA) has no practical limit, and currently are available up to 32 GB.
  • Whichever media is selected, you can use a sort of disk ring buffer to ensure that the most recent data is preserved (sacrificing the older data)
  • Triggering the system, especially for higher speed channels, can often lead to huge space savings. Transitional recording is another option very appropriate for channels that basically "stay the same" a lot, but must be sampled fast for those few "rare" events.
  • If you are using an autostart or diskstart, these can be stored in the device's flash memory, and so that it may be possible to have someone swap memory cards periodically, without needing access to a PC or the imc software.

Can anyone share experience with data storage (CRONOS-PL) - removable disk (CF or PCMCIA) vs PC hard disk?
Does using the RD free up PC recourses and improve on screen data viewing and data storage (medium channel count / high sample rates)?
Is it better to just increase the PC memory?
Does anyone use or provide some details on Transitional recording?
Thanks
