There's no one-size-fits-all answer. Checksumming filesystems aren't appropriate for any use either. Some people use version control systems which obviously have many advantages above simple checksumming (and yes, some are especially designed to be used with large binaries). Many backup processes us...

I agree using better hardware on the NAS wouldn't help much (which is why I would recommend higher-level checksumming). But using a checksumming file system would help even less. I've of course have had bad sectors. Finding what files were affected shouldn't be so hard, unless many files are read an...

My unsubstantiated* opinion is that if is your data matters and you have no way to check it for integrity at a higher level than the filesystem/OS, it's more important to use a server mobo and ECC RAM because checksumming filesystems are only as good as the hardware they run on. And they naturally o...

Torrents have checksumming built in. You might need checksumming for other stuff but it'd waste less resources if you didn't use a checksumming file system to hold the data which is included in a torrent anyway. Connecting a bad drive could in theory damage the hardware you're connecting it to. Cert...

I'd build by own NAS but... Why do you need ZFS or BTRFS for? There are more robust alternatives depending on what you want them for. Likewise people sometimes waste resources on pointless server encryption. A NAS has little need for a SSD by the way. They're convenient and can be pretty cheap as lo...

Clueless reviewer strikes again. The TDP value isn't defined for any individual CPU, nevermind for a particular frequency. Typically, CPUs never consume as much power as their TDP. Measurements would be required to confirm that this part is simply a factory-nerfed version of a similar non-T CPU but ...

Encryption could mean so many things... ask them! For instance it could mean the NAS allows you to use the encryption feature of the drives. You didn't explain why you wanted encryption for (anything "supports encrypted storage") so I can't comment on what might be the best ways to achieve your goal...

There probably are pretty quiet 3.5'' drives nowadays and there are ways to lower the noise of your existing drive (see other threads in this forum) but I wouldn't bother looking for reviews and such if you only need 1T. Just get a 5400rpm (or thereabouts) 2.5'' drive. Hitachis are the ones I have m...

So plus according to my screenshot, MS support engineer's answer "However in this case you wouldn’t have lost any data." is 100% right? In other word, Are data clearly untouched and sectors are not remarked by chkdsk in my case(in screenshot)? I don't know exactly how chkdsk works but I don't think...

The point was that SDDs will (I believe) fail erratically and suddenly. In most cases a HDD will give you warning signs of impending doom. With due respect to your beliefs, HDDs often fail without warning (or give warning but keep working) while SSDs may also give you warning. The main difference b...

Xen, your comments about storage reliability are plain irresponsible. If you have had experience with 18 drives, you don't have much experience. I don't consider myself as having much experience but I have more, enough to know that drives do fail: Flash, HDDs... they all fail. Reliability has increa...

I don't know why you're wasting your times writing these endless posts that few (if any) are going to read as opposed to skim. I agree with some of your points and in particular about the irrationality underlying blanket recommendations like "you should put your OS on an SSD". But your rants have ba...

I've seen a similar problem with the major W10 updates as well: don't know if it's stuck and you should reboot it or if waiting a bit longer would allow whatever is in process to finish cleanly. And you can't defer these updates long on Home.

Unless you are loading the GPU heavily the total power use will be minimal. Which is the most important reason why TDP is irrelevant in that case. As I said before, reviewers have actually measured the 12V CPU current on haswell chips and found it lower than previous gens. People have of course bee...

If you only loaded the CPU, yes. But that would make most TDPs grossly... irrelevant. My apologies if this was not clear, but I hope it was implied that we are talking about otherwise identical systems. Only changing the MB/CPU and RAM if needed. Same disks, PSU, etc, no separate GPU. My point was ...

Now you are just making stuff up. There is no way you could have actually tested this and gotten those results. Let's not rush to conclusions. Some cheap measurement devices are especially bad at charaterizing small loads. But now a Haswell CPU idles at less power than a desktop Atom at load. Again...

The G1820 doesn't have a TDP of 53W. Intel's numbers are misleading. I don't know for sure in this case, but it was true for the older Atoms. They were so slow that they would actually use more power in the long run completing compute intensive tasks. Race to idle is a valid power saving method. Not...

Well, there's a few D510 boards I need to sell... I'd make them cheaper than half of the original price for you. :-) If you're in Europe that is (otherwise shipping might be too costly). And yeah, the Haswell Celerons are generally much faster, especially at single-threaded operations. With the olde...

Make sure you understand the difference between spinning and spinning UP. Maybe that's what you meant because there are drives like WD Greens which do not use too much power to spin up but going by specs you could easily top 80W by spinning up 4 faster drives (never mind the rest of the hardware). M...

Something else that came to my mind: I see you have two 3.5'' drives which probably have three platters or more each. Make sure the DC-powered board you're waiting for supports that! I'm using a DC-powered board for my home server but I'm running slow 2.5'' drives with it... fat ones with many platt...

Maybe your old board can't do it if it's got a really old chipset but you can put desktop hardware in standby (suspend to RAM) nowadays. With a decent power supply, your NAS would consume very little power in that mode and be up much faster (after you send it a WoL packet) than if it were fully shut...

Oops! I forgot that the OP wanted an old PCI slot. I guess it's for the tuner. I think there are old MSI Celeron 847 boards which are fanless, have 4 SATA ports and 2 PCI slots. They ought to be reasonably efficient. But they're not stocked here anymore (not by large retailers and their suppliers an...

Based on your post in the Braswell thread, it's not to late to answer. The parts you posted are massively overkill for a NAS. A NAS has no use for anything but the cheapest Celeron. And of course a low-power board would be fine. Looking at the new ones currently selling here, you got the cheap C70M1...

I think weekly fsck/par2 checks are way overkill. You might start out doing weekly checks but if you don't find any issues for months on end (as expected), consider make such checks a lot less frequent. Then again maybe git fsck would find problems with git rather than storage problems so perhaps th...

In my experience and according to my reading, other causes of bitrot such as crappy controllers (it might be their RAM, but most people would think system RAM when you say "RAM") and buggy software (uncommon firmware especially) seem to be leading causes. Although it seems most things (RAM included)...

I wouldn't rule out the compatibility. The CPU seems to be a Bay Trail with a regular Intel GPU. So far this shuttle XS35V4 seems like an extremely good option. Any other machines I should consider? The other Shuttle has a mainstream Intel CPU that's probably marginally better for your usage and whi...

Prime 95 Large FFT 1.0V (stock) @ 3GHz: ~78W 0.8V @ 3GHz: ~68W Idle 0.8V @ 800MHz (same value whether undervolting or not): ~52.5W Worth it? Yea my stock heatsink seems to think so. Only worth it if you crunch a lot of numbers and basically useless when idling. That's generally been people's experi...

It's not that simple anymore (for one thing, the autonomous voltage management may disregard your settings). Measurements are required to assess any actual power savings. And no task will ever cause that CPU to burn 70W. Likely not even half unless you torture-test the GPU. Obviously there's more po...

Whatever you like. Do you actually save a significant amount of power for instance?
What actually happens with the CPU voltage isn't as simple or transparent as it used to be...

And for what it's worth, I disagree with your assessment of the market.

Not necessarily. Have you measured the effect?
