Re: Silent/quiet small NAS. Need help with cooling, PSU and

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...

Re: Silent/quiet small NAS. Need help with cooling, PSU and

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...

Re: Silent/quiet small NAS. Need help with cooling, PSU and

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...

Re: Silent/quiet small NAS. Need help with cooling, PSU and

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...

Re: Silent/quiet small NAS. Need help with cooling, PSU and

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...

Re: The idiocy of Intel's T desktop processors

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 ...

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...

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.

Re: Low-power NAS build

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...
