@samueldr:matrix.orgsamueldryou have to do heavy modifications to use PCIe17:40:58
@vika:matrix.nice.sampler.fivika (she/her) 🏳️‍⚧️You can always use a soldering iron17:41:03

@samueldr:matrix.orgsamueldrCM4 is not a product in itself17:41:03
@vika:matrix.nice.sampler.fivika (she/her) 🏳️‍⚧️people've done that17:41:08

no, USB is not valid :) especially not given how self-powering from USB is a recipe for disaster
wdym?
17:41:30
@samueldr:matrix.orgsamueldrif it's not out of the box, it's not a solution, sadly17:41:30
@Las:matrix.orgLasI've been using an SSD from USB for some time now and it works fine17:41:37
@samueldr:matrix.orgsamueldralso, few CM4 boards have a nice layout17:41:45
@Las:matrix.orgLasSure, IOPS isn't great but it's still way better than an HDD17:41:49
@samueldr:matrix.orgsamueldrmost are meant as a development platform17:41:54
@cepheus:mtx.ceph3.uscepheusi mean part of the issue is that the SoC they're using has a pretty anaemic number of PCIe lanes, no17:42:00

Backpowering from a non-compliant USB hub that doesn't use diodes on +5V bypasses voltage protection and can fry a Raspberry Pi

* Backpowering from a non-compliant USB hub that doesn't use diodes on +5V to prevent power from leaking bypasses voltage protection and can fry a Raspberry Pi

@Las:matrix.orgLasI'm not using a Raspberry Pi, I thought his statement was wrt. USB in general17:42:43
@Las:matrix.orgLasI don't understand why anyone would buy an RPi honestly17:42:53
@samueldr:matrix.orgsamueldr vika (she/her) 🏳️‍⚧️: by "self-powering" I mean USB drives without an external power source 17:43:40
@Las:matrix.orgLasUSB drives?17:43:52
@samueldr:matrix.orgsamueldrhard drives, SSDs, thumb drives17:44:07
@Las:matrix.orgLasI just bought a SATA 3 <-> USB 3 adapter from Sabrent17:44:13
@samueldr:matrix.orgsamueldr * hard diss, SSDs, thumb drives17:44:15

I don't understand why anyone would buy an RPi honestly
it's dirt cheap, doesn't take much space, doesn't require too much active cooling (just an optional fan if you want to overclock it) and doesn't use too much power
17:44:26
@vika:matrix.nice.sampler.fivika (she/her) 🏳️‍⚧️perfect platform for a small home server or a homelab if you've got several of them17:44:45
@plabadens:matrix.orgplabadensthe RPi ecosystem is pretty good, especially for education17:44:47
@Las:matrix.orgLasI'm using an ODROID N2 personally17:44:48
@Las:matrix.orgLasIt was 80 USD IIRC17:44:56
@samueldr:matrix.orgsamueldrin my experience it's, in the best case, a matter of hour (singular) until the pi just freezes because it stopped sending power to the USB ports long enough that the drive has disconnected17:44:58
