I’m setting up some raspberry shake units for offline use and field deployments, and would like to mount an external USB for storing the waveform archives in case of power failure and/or the microsd card fails (i.e. https://manual.raspberryshake.org/usbsds.html). Can anyone suggest any ‘industrial USB’ drives that would be suitable for this purpose?
Hi @olamb245, if you are looking for true SLC (“industrial”) storage, our general rule of thumb is that if the manufacturer does not explicitly state that the memory architecture is SLC it’s a no-go. Delkin sells a line of MLC and SLC USB drives that may fit what you’re looking for: https://www.delkin.com/products/industrial-usb-flash-drive/

Let’s hope the writer has deep pockets. A 16 GB Delkin is $471 from memory4less. You could save by getting them from AVNET who will sell them to you for $250 each, if you buy a minimum required quantity of 20 - so $5149 for the order …

Yes…I should have mentioned: there are no “cheap” SLC devices.

You should try a quality USD drive I am using https://www.allhdd.com/hp-741279-b21/ it is working fine. Or you should use an External SSD because these have a large amounts of storage and they are cheap as well.

I recommend looking into industrial-grade USB drives from manufacturers like Transcend or Swissbit. These drives are specifically designed to withstand harsh conditions, with features like enhanced durability, extended temperature ranges, and better endurance compared to consumer-grade options. They are ideal for applications like yours, where data integrity is essential in the event of power failures or SD card issues.or try to use an external hard drive like Dell 2TB External Hard Drive 7.2K RPM SATA-II 06C10R Refurbished

Thank you so much for these details about industrial USB drives!
(and welcome to the community!)
I’ll integrate them into our manual so that future users will be able to find them easily.
