Thanks for the advice, noted! I was attracted by the compact size, I guess it’s not realistic that it would handle 5 disks…

You’re starting to convince me, I’ve been looking at getting a GMKtec G3 N100 mini pc and just slotting it beside my existing NAS. I can even get a dedicated gigabit ethernet connection going between these two.

Interesting, I’ll investigate this!

Yeah, I’m also upgrading from a 14 years old Intel Atom D2701. It has a TDP of 10w, at the same time it has roughly a tenth of the performance of an N100. And then the HW accel for encode and decode is in addition to this, fot this type of task the difference is larger than 10x - the D2701 cannot do transcoding.

Thanks, the Jonsbo N1 actually has five hotswap bays, and I believe you can squeeze in another 3.5" besides the PSU if you have a small PSU. I’ll consider the N3 but I don’t think it will fit where I have my current NAS so I’ll have to replan a bit.

Yes, I’m thinking about either getting a PCIE SAS HBA to open up the option for SAS drives, or to get an ASM1166 M.2 to 6xSATA.

You’re right that I’ve focused too much on ECC, I think I’ll see it as nice to have more than something I’d prefer to have.

You’re right, I probably don’t need ECC. I’m mostly worried about bit flips in my important data, and as you say, a checksumming FS and RAID will protect against this while the data is in storage. However, it doesn’t protect against bit flips while copying data, for example copying data to backups - but there are other solutions for this, which I should consider.

Hot swap is nice to have. I haven’t even considered that it wouldn’t be supported by a mobo, I should look into that, thanks. These are the mobos I’m considering for each option:

N100: Topton N100 motherboard, 4x2.5G, 6xSATA, PCIE x1 https://a.aliexpress.com/_EvVv0k6

8500G: ASRock B650I Lightning WiFi (Gigabyte A620I AX might be an option, but it has only one M.2 slot so the upgradeability is less)

13100: ASRock Z790M-ITX Wifi

The N100 option is cheaper and should be lower power, but as you say I worry about needing another upgrade in a year or so, and this option doesn’t offer much upgradeability so that would mean at least a new mobo and cpu. The other options could accommodate a beefier CPU if needed.

Yeah, old Xeons tend to not be very low power, also I don’t think I’ll be able to find one with a mini ITX board to fit it in a compact case. Also, I’d probably need to add a discrete GPU, which adds to the cost and power consumption.

I want a low power build to limit heat and noise produced in my office room, to limit the electricity bill and as I understood it the case I’m considering also doesn’t have the best thermals, so I don’t want to put a CPU with too high a TDP into it.

The ReadyNAS 626 actually has a Xeon D-1521, but with a quite low TDP - 45W.

Regarding budget, I’m aiming for 400-800$. The N100 option, including case and PSU (but not disks) is at the lower end of this, while the 8500G and 13100 options are at the upper end.

Ah yeah, that’s what sex on the first date means

Mmm yes, compress me harder baby

All the better for us running Linux!

This is great, but the context is that this is for specific inner loops, and it is compared to the C version of that specific inner loop. Typically what was used before this on a computer with avx512 was the avx2 version of the inner loop, and the speedup compared to that version appears to be up to 60%: https://x.com/FFmpeg/status/1852542388851601913 . Then as not a specific inner loop isn’t run all the time, the speedup is probably much less than 60%. This is still sizeable, but the actual speedup in practice with this implementation is far far from 94x.

Yeah 7000-series Ryzen benefits from the avx512 code paths in ffmpeg. I’ve benchmarked a 5900x vs a 7900x specifically for software H.265 decoding and there was a sizeable difference.

For example, maybe branching is something you’d like to be able to do without it being a nightmare?

They meant the command dtrx, the combination of dtrx as parameters to tar make no sense. Extract AND append?

Then comes a .tar.bz2 file along and you’re screwed. xtract je vucking file?

Pro tip: -z, -j are not needed by tar anymore since many years, tar will autodetect what compression was used if your distro is anything remotely modern.

Is there a 6502 backend?

Why are these QFP chips through-hole? Looks like the bastard child of QFP and DIP.

Under Santa’s hat

Agree with you fully on the shortcut front, and it’s very confusing that ctrl is separate from the command key. The whole keyboard layout is also a nightmare, but this is probably because I’m in Sweden, where the Swedish mac keyboard layout is radically different from the normal Swedish keyboard layout that all other computers use. When I help out someone with programming on a mac, I always end up telling them “please press pipe” or tilde, braces, backslash, or even at-sign, as these are not printed on the keys. They are accessible through the option key, but you’ll have to test all combinations to find which one is where and memorize this.

I looked up the backgammon start position, since then all Google wants to sell me is backgammon boards.
