Another thought, are there any blower/radial/cage fans with the right height we could adapt. Many radial fans are fantastic at static pressure compared to an axial fan of similar noise level. However, most of the ones I see have an intake on the wide/flat side and output to the narrow side...

That seemed wrong to me so I checked the drives I dont have installed. All intel (so maybe specific to them) but both my Optane U.2 and intel DC U.2 specify 12v AND 3.3v on the label. However the 3.3 is in the 10mA or less, so a small 3.3v regulator *should* be fine. Going the other way, 3.3v...

So, looking over this a bit more I'm not sure if the math on the fans when in series accounts for the many issues with putting fans in series (and why so many series configurations have the fans rotating counter to eachother, among other airflow design elements). At minimum you'd need...

If any of the Gen4 stuff is affordable yet I'd also love to know (any) to (any)2x or 1x as well Also if anyone has seen any gen4/5 with the downstream being only Gen3 that could be interesting

Holy crap what a post! I'm going to have to re-read this when I have more caffeine, and IQ :eek:

I mean AFAIK this is stuff deep in the Kernel, the "TrueNas"-ness will come with with how (in)frequently they update the kernel and the general unwillingness to do any kernel patches for the distro that are not for stability. I already have developer mode turned on for the one I use as a NAS...

Set aside the project for now. I may try one of my other drives of the same model in a machine with a more up to date kernel, and failing that try a custom kernel, but likely not in my nas machine.

I've seen a few that are just the card riser part, annoying overpriced for what they are (30 bucks for the one I saw). Have not seen any that handle the bracket (also the screw hole is in the wrong spot but I could solve that with a drill/Dremel ;) ) Oddly I'd almost prefer *just* the bracket...

Bit of digging: Looks like there has been some.... lively discussion over the years in the Linux kernel mailing list etc. There seems to be a bit of... pedantic sticking to a strict (IMHO incorrect) interpretation of the NVMe spec that sort of leaves drives with more than one namespace...

Another thing that optane tends to be really good at: Not caring that the workload is reading and writing. A LOT of NAND drives, even enterprise, not only perform much worse than label in typical workloads and small I/O (your worst case 4k read/write) will ALSO struggle more with *combined*...

Radeon R5 340X also look fairly cheap, but not finding power use numbers at the moment. Related: anyone have good solutions for using low profile cards in full profile slots that isn't "bend up the tab or have the right bracket".

Endurance on a 32gig is 182TBW, on paper SLOG usefulness is VERY situational however, and for spinning rust I'd go with the even cheaper 16GB. IIRC the formula is ~1GB of space per Gb of network transfer speed. it only helps with SYNC writes, so limited use for most of us. FWIW I have abused...

Do these 'act like" USB thumb drives? I have a NVMe USBc enclosure now that shows up as an external hard drive. Most of the time that still works, sometimes it leads to issues with what various software/bios' "expect"

Truenas scale 25.04 D4800X Series Optane SSD Device supports 16 namespaces. When attaching the second namespace the first one vanishes from `lsblk` and `/dev/` Removing the second namespace and the first one shows again. dmesg complains about duplicate eui64 which is correct, but the namespaces...

Thanks for the suggestions with idle power use cited :)

Yeah, quick google search isn't getting me the idle on that, but added to my "to be considered" list, thanks

Looks to be 100-150 refurbed, not my idea of "inexpensive" lol. Bigger issue is it looks like they are using the old "mini displayport" ports?

Not transcode, just display. But thanks :)

In 2025 what are the good options for inexpensive low idle power (so it can be used in systems that are on 24/7 if needed) preferably single slot (2 slot is fine) GPUs for systems without an iGPU or remote management. Yes, I love remote management, and iGPU, but we work with the hardware we...

Write amplification. It's been a hot minute since I really dived into specifics, but as I recall few (if any modern) SSDs are actually 512b under the hood, and writing 512b still requires a larger free area (and erase pages are even larger, but thats a whole other discussion). IIRC even many "4k...
