I googled "sandisk cruzer fit 32gb planar tlc" and it returned this: The SanDisk Cruzer Fit 32GB is an ultra-compact, low-profile USB 2.0 drive optimized for permanent plug-and-stay usage in car stereos, TVs, and laptops. Regarding its NAND technology, it uses cost-effective planar (2D) TLC memory, prioritizing space-saving portability over high-speed read/write performance. Conversely, when I googled "sandisk cruzer fit 32gb 3d tlc" it returned this: The SanDisk Cruzer Fit 32GB is an ultra-compact USB 2.0 flash drive intended for "plug-and-stay" storage in tight spaces (like car audio or smart TVs). It does not utilize 3D TLC NAND; it is a legacy USB 2.0 drive built on older, lower-cost controller architectures. I guess there's a possibility that google is wrong...

Thank you, Lolight, for taking the time to respond with such complete information. Based on your reply, using a mirrored USB internal boot pool without TPM or fTPM would still leave me with a single failure point: the dedicated USB license anchor. So that's really not a good option, not really any better than a single USB boot drive. So based on your information, I plan to stick with the single USB boot drive. I do backup the flash drive weekly (I assume that's what you mean when you mentioned the Unraid config folder backup), and I have a script set up to automatically rsync those backups to my QNAP NAS. Would the Innodisk USB drives still be a good choice for a single boot drive setup? I have been using a 32GB Sandisk (Planar TLC) for over a decade without any issues, but it sounds like it would be a good idea to replace that drive with something better. I'll make sure to pick up an identical spare drive as well. From what I can tell, using a USB drive larger than 32GB is supported these days by the Unraid USB Flash Creator.

Background: My primary interest in using internal boot drive for my Unraid server is for redundancy. Decreasing boot speed is a distant second. Even though I believe my motherboard supports TPM 2.0, I don't think I want to tie the Unraid license to my motherboard. Since I am using both of my motherboard M.2 slots for cache drives, and I don't really have any slots to mount SSDs, I am thinking that using two USB thumb drives in a mirrored internal boot drive setup might be my best option. I am currently running Unraid 7.3.1, but will be upgrading to 7.3.2 early next month. Questions: Once I setup the internal boot drive(s), my existing USB thumb drive will no longer be valid to use in Unraid. I could, however, utilize it for any other purpose, correct? In the future, if one of the USB thumb drives failed, Unraid would seamless switch to the other drive and notify me that the other drive has failed, correct? If I am not using TPM and I need to switch motherboards (hardware upgrade or failure), I could just plug one or both USB thumb drives into the new motherboard (along with all of the array and cache drives) and be up and running, correct? If I head down this path, I am planning on purchasing two 64GB INNODISK LYTX DVR-70 drives (per the Unraid Boot Device Guide). The drives are USB 3.0; should I be plugging them into USB 2.0 or USB 3.0 slots on the motherboard? Also, my understanding is that Unraid will create a 32GB BTRFS partition, with the remainder of the drive(s) formatted as ZFS. Is that correct?

I'm using the :beta tag, and just received a notification that there is an update available to apply. What is the current recommended procedure to use to apply the update to the docker? Is it as simple as stopping the docker, waiting for the docker to fully stop, and then clicking the "apply update" link on the docker screen in Unraid?

Thank you, I'm now playing with the beta version, and learned a few things about Unraid dockers along the way!

I just installed this docker, seems to be working well so far. I notice that the controller software is only version 5.13.30.8, what needs to happen to get it updated to version 5.14.20.9?
