Not a traditional HDD, no. Either a USB stick or an SSD. I opted for an SSD for the better durability under repeated overwriting. These days they really aren't that expensive, especially in the moderate sizes appropriate for the task.

I formatted a 1TB USB drive with two EXT4 partitions; one for music, and one for TeslaCam. It took me a while to figure out that the TeslaCam partition needed to be FAT32. The troubleshooting process was kind of annoying and yes, definitely a mystery. I wanted to use EXT4 because it's journaling so it would better tolerate being unplugged while mounted.
My setup ..
I assembled a 128GB M.2 SSD which is partitioned into 20GB for music and 100GB for TeslaCam. The SSD is plugged (USB-C to USB-A) into a three port Sabrent USB 3.0 Hub and velcro'ed to the underside of the mobile phone dock. So far its been very reliable.

Yes, sorry, I thought i mentioned twice that ext4 only works for the music partition, but maybe I wasn't clear enough. Glad you figured it out anyway!
No cabin overheat protection?
Mine was good in the center console in Death Valley and in Phoenix during their heatwave at the beginning of July with temps like that, but I did keep cabin overheat on.
We dont have any covered parking at work and I am not sure I can keep the cabin overheat protection running for 8+ hours every day
As long as you have plenty of charge for your drive, there's no harm to having Cabin Overheat on for 8+ hours every day. It'll eat some range, especially in that climate where it'll have to hit the A/C compressor a little, but it's better than letting the cabin reach 150+ like happens with other cars IMHO.

Mine has not had any problems between the cold of winter and the recent heatwave. Although I have cabin overheat protection on, and have not left it in overly hot situations for very long or on a regular basis.

Do you have a source for this statement?
I'm struggling to find any test data on the subject. There's lot of discussion about the longevity benefits of an SSD, and lots of comparisons of power usage against HDDs with some rather mixed results. But I'm not finding anything on the consumption of USB sticks, let alone comparing them to SSDs...

The Samsung T5 SSD lots of folks like lists in its manual max consumption of 4 watts (5v at 0.8 amps)... (anandtech found about 0.38 watt draw at idle, so about 0.08 amps)
https://www.samsung.com/semiconduct...ble_SSD_T5_User_Manual_v0.0_Rev01_English.pdf
Here's specs on Sandisk MicroSD card power requirements-
https://www.alliedelec.com/m/d/04db416b291011446889dbd6129e2644.pdf
it's showing 0.035 in idle/sleep mode... 0.2 amps in high performance mode.... so roughly .175 watts and 1 watt respectively...
I suppose in that example it's "only" 2-4 times less....I've seen other threads (with linked sources) with a 10x difference though if you're curious to search for em.

Unless you're literally running on sparks and/or charging two phones at the same time, the amperage and temperature tolerances are negligible, even at 4x the rate. If one needs the storage, SSD is always going to be superior.
Also the temperature operational tolerances in the manual do not match the actual hardware tolerances.
https://www.samsung.com/semiconductor/global.semi.static/T5_2019_brochure_Simulation.pdf
I'm not digging that up from some obscure website. It's the "Brochure" from here:
Samsung Portable SSD T5 | Samsung External Storage
Also as many cite here, I've gone now two months in the summer heat with no problem. 130+ temps. Se
My recommendation is always to go with SSD for storage, and there's virtually no impact to your driving range as a result of this. It would have a minor impact to a second phone, potentially, if you were actually charging two devices.
Side note: I deliberately ran my car to 1% battery - halfway by accident, halfway on purpose. I wanted to do a low-to-100% charge to recalibrate my Model 3 battery and decided 7% was too high, so figured I'd just take the next exit off the highway and turn around. ...... The next exit, as I found out really quick, was quite a few miles down the highway. The car immediately told me to slow down to make the destination, etc ... I did all that, and still had a few dozen miles to go and 1% charge. I saved the most power by just turning off the A/C.
I didn't even consider turning off my SSD. Or stopping to pull my phone off the Qi charger. The power pull there is inconsequential.
So really, for anyone considering (or not considering) a SSD, don't do it based upon the power draw, unless you really actually need to charge multiple devices at all times while you're driving, and need all devices to be constantly high rate. Peak power draw isn't constant, and there are more important things to worry about.

Huh? He asked for support for the fact SSDs use more power. So I answered his question with sources.
What's the issue with that?
It's pretty common folks might wish to charge 2 phones at the same time, unless you've never got anyone in the car with you.
On top of that, many are using cheaper splitter/hubs that might limit available power on any given port so it'd be relevant there too.
And of course anything using more power reduces range, though I'd agree you're talking about it doing so by amounts that PROBABLY don't matter to most people.
Not really.
Besides using more power (which I'd agree is a very minor issue if it was the ONLY issue, though it's still one against not in favor of SSDs), they usually cost more, and come with a shorter warranty too (3 yrs on the T5 SSD for example vs 5 years on some keys/SDcards)- they're also physically larger (and more easily spotted by a thief) and have narrower environmental temp specs.
All in exchange for... pretty much no practical advantage in this use case at all- unless you need a HUGE amount of space (>256GB) for music because really massive SDcards/keys are more expensive once you get that big.
Now THAT is a here we go again
Environmental temp ranges and device operating temp ranges are two different things. Stop conflating them.
Again, the actual manual-
https://www.samsung.com/semiconduct...ble_SSD_T5_User_Manual_v0.0_Rev01_English.pdf
Samsung said:
That's the exterior environmental/ambient temps it officially supports using it in.
YOUR link is how hot the operating drive itself is allowed to get (which is obviously always higher than ambient temp for running electronics)
35C is 95F for the metric-challenged BTW.
So according to the maker of the device using it in ambient temps above 95 F is out of spec for the hardware.
Absolutely it'll probably work fine for a while. Probably a good while, MFG specs are always conservative.
Meanwhile the same maker advertises their SDcards and keys as "temperature proof"
So I was using a Samsung USB flash drive...link:
Samsung MUF-128AB/AM FIT Plus 128GB - 300MB/s USB 3.1 Flash Drive https://www.amazon.com/dp/B07D7PDLXC/ref=cm_sw_r_cp_apa_i_c1ZwDbJCAHA5B
For the last 2 months with no issue..
All of a sudden on Saturday I started getting an error that the drive is too slow to record videos. If I take it out and put it back in it works for a while then I get the same error.
Has anyone encountered this?? Would switching to SSD help?
