the thought process between RAID5/6 and what unraid does is fundamentally the same, but the way it is achieved differs.
 
in a RAID5/6 array everything is written "across" all drives, splitting at a bitwise level just like RAID1 does, for example if you have a RAID5 with 3 disks, half of the data is on one disk, half the data is on another, and the third contains the parity data. raid6 just adds an additional slice of parity data.
 
unraid stores files on 'data' disks in their entirety, the parity disk (or disks) then store the same style of bitwise parity calculation of the data on these data disks.
 
the key difference in the parity calculation is that RAID5/6 splits data and parity across all drives, and unraid dedicated specific disks to parity operation.
 
essentially, the data on a raid5 array looks like this:

and an unraid array would essentially contain A-D1 on disk1, A-D2, on disk2, A-D3 on disk3, and A-D parity on the parity drive.
 
essentially if we ignore the way the data itself is stored (striping vs whole files) and the way the parity is stored (dedicated parity drive vs spread out) they both do the exact same thing.
 
for parity calculation sake each drive is just a big row of bits: one or zero.
 
you then put all of those rows side by side, and your parity is also just a big row of bits, each one is the XOR result of the other bits on that place in the row. the unraid page @Kilrah linked does a good job at explaining this process.
 
the difference in methodology that unraid uses compared to traditional RAID5/6 has one very interesting benefit for home users: as long as your parity drive is equal in size to the biggest drive in the array, you can use any odd mix of drives you like and the parity mechanism isnt affected. this is displayed in before mentioned unraid page by having different length bit rows in the example.
 
on another note; this is why on unraid's webinterface on the main page all disks have a "disk usage" bar, except for the parity drives, because they are essentially "always full"; they contain a full array of XOR data, no matter how much or little is stored on the rest of the array, or no matter how big or small the other drives are.

but the CM3588 doesnt run anything that isnt compiled for ARM, and just about everything has a version compiled for x86. besides, you can buy N100 boards for around the €200 mark *here in the west* without dealing with aliexpress shipping taking a month.
 
also, the N100 is a beast among low power CPU's, like you state it 'can' turbo up if needed, but the embedded parts dont actually use *that* much more. besides, the RK3588 is quoted as being a 12 watt part for as far as i can find. on top of that, i'm pretty sure all of the embedded intel cpu boards have an option to disable the boosting all together if you absolutely want to go for efficiency.. but we're at the point that the drives will be using more power than the CPU.
 
also, your comment is irrelevant because:
 
having that said - both of these platforms have one shared issue for OP's requirements:
they're both limited on PCIe lanes, and by extension SATA.
 
if you go up to something i3-something or ryzen 3 something, you can still enjoy quite good idle power draw figures (like, actually shockingly close to on par with the embedded systems these days), but you have the "oomph" to run game servers, and the expandability to add several HBA's for extra drives if so desired.

last i heard his "daily driver between reviews" is still the note 9. it comes up on WAN show every so often.

he's probably using it for a phone review, so if you're interested, probably wait a month or so, and you'll see a review pop up on LTT.

i went digging for power draw figures on the rockchip, and the best i can find is a 12W TDP, so depending on how much it has to work you might have a whole lot less.

ground = "negative".
 
in cars everything is reference to the chassis aka "ground". so your 12 volts is between the battery's positive terminal and the ground, your accessory power is between the relay for that and the ground, etc.
 
ofcourse there's someone who bothered to document the whole thing:
https://old.pinouts.ru/Car-Stereo-Toyota-Lexus/Toyota_W58802_Head_Unit_pinout.shtml
 
B+  => goes directly to the positive of the battery / power supply (your standby power for the clock, etc.)
Ground => your "negative" side
ACC => connect this to the positive side to turn on the radio.
ILL => controls the backlight, presumably this is for day/night mode, in the car this is connected to your lights.
ANT => this is power out for a (retractable?) antenna.
AMP => presumably a power toggle for external amplifiers.
 
 
that all said, here's a fun trick for you to use in future projects:
 
see how that GND pin is connected to a very large surface, to which the connector itself is also fastened? that's almost always your ground, which goes to the "negative" side of your power supply.

because most common tasks genuinely take longer on linux.
 
gaming? expect to be troubleshooting before the game actually works.
office tasks? good luck with LibreOffice. i have both libre and MS office on my computer, libre is a freaking joke, even compared to office 2007.
photo editing? enjoy your subpar alternatives.
 
it's not some toxic opinion or a "dis of linux users". it's a very very sad truth: the reason why linux on the desktop hasnt happened so far, is because up until now, compared to windows or mac, the experience of *actually* daily driving linux on a computer you *actually* use for more than a webbrowser.. linux suuuuuuucks.
 
i have a linux desktop as a media pc, i have a linux laptop, i have a linux server, i have an unraid server. and i'll tell you: server? great. desktop: holy hecking please no, i waste so much time with these devices that i simply dont use them.

it's the last one they have, so i assume not.

it's not weird, it's just some mild irony that a microsoft person happened to happen upon the backdoor while working on something entirely unrelated.. as opposed to the maintainers of the affected distro's.
 
having slept on it, perhaps the power of this exploit is also it's weakness; it fiddled with SSH logins, so anyone doing in-depth testing on performance that just so has happened to SSH into a system with their monitoring running... they would have been likely to catch tomfoolery going on.
 
beyond that.. this also shows the painful reality of ecosystems like arch linux, as they essentially have no method to protect against this.

except.. you're wrong.
 
there might be nefareous enities that mis-label teir product as AI, but the way AI works is really interesting. maybe you should go watch some videos explaining it before you ask people to spread some baseless conspiracy theory.

so... "no one is safe" because of a commit that only made it into a dev build of fedora and debian?
 
while this is a potentially very big backdoor.. it seems that humanity had some karma saved up, and a microsoft dev of all people just happened upon the backdoor while working on a dev build.
 
the short of it is; if you havent updated in the past few days, there is no reason to suspect your system is affected.

part of the "verification" process is that the games run well at native resolution with reasonable settings.
the games that dont run well out the box get "playable" instead.

that's already wrong. you want the light level to 'match' the surroundings, so that it's easy to read, but not overly bright.
 
past that, make sure they're at eye height, and the distance between your eyes and the monitor is adjusted well so you can easily read any text you may encounter.
 
also - i'm of the opinion the "illuminated room" thing is mostly a myth. you want light level to match between the display and the surrounding room. that's ofcourse easiest if the light level is set artificially too, but that doesnt mean it has to be all bright all the time. i find bright rooms straining in general, wether or not a display is involved.

i mean.. it could be broken, there could be cables missing, the disks might not be plugged in all the way, .. this is kind of like asking someone on the other end of the planet where you could have left your keys.

all the proliants i've dealt with have the slots piped trough a raid controller on the motherboard. depending on the age i should also note they may have disk size limits.

Just an activation key by itself won't let the company access your computer.
 
However, if this is a work computer, they may have installed some remote access or management software. (Especially if it's enrolled in a Windows domain.)
 
Microsoft also allows large companies to run their own activation servers (called Key Management Services), which computers have to check back against periodically. You would have to connect to the company's network (physically or over VPN) so your PC can check that it's still activated on the KMS.
 
NEVER buy KMS keys from sketchy resellers!

perhaps ellaborate on what exactly you'll be hoping to run on this.

i'm confused by what you mean with "for a cashier"?
 
are you just saying she's a cashier and just happens to need a laptop on the cheap.. or is this a laptop to be used by a cashier for their cashier duties?
 
because if the latter - you should be buying something reliable, because downtime means income lost.
 
and if the former... the point that your aunt is a cashier is entirely irrelevant.
