@bwDraco to be fair at the 209 AU Drange the comparison point would be Celeron... which is also shit
but I just wanted to pick up something that could play a video in a web browser (which is unfortunately surprisingly demanding these days, but even then an Atom x5 or above should handle it no sweat)
the 32 GB eMMC is a bigger problem than the CPU choice :\
Low-cost planar TLC NAND + DRAMless controller + low capacity + high write amplification (because the drive is often close to full) + low RAM + software not designed to minimize writes = bad SSD endurance.
Hmm... 4 GB RAM. At least there's a tolerable amount of memory.

@Bob True, for the average consumer they'd maybe want to choose a more reliable drive but in practice at the end of the day if your drive dies it dies, unpredictable failures are by definition unpredictable so it doesn't make any real difference.
Maybe they'd feel better if they thought theirs had a lower chance of failure than average but that doesn't give you an excuse to not have backups.

@MathCubes the 4770K is objectively a better CPU, but if you're just using it for NAS functions and nothing else, the 2500K is probably fine... hell, even if you use it for video / audio playback it should probably be fine
@HornOKPlease if you're not using deduplication 8GB is plenty, IME; at least, I have 10TB of ZFS storage and 8GB RAM and member pressure is never an issue even sharing that with a bunch of daemons.
@MathCubes not sure that's ideal, to be honest - if the storage is attached to the same system you aren't really benefiting from having a separate array, unless you make the backup array store deltas and keep prior versions
@MathCubes ZFS has a feature that lets it deduplicate blocks, so if two files contain the same data the data is stored only once and shared between both files.
If you have lots of duplicate data this can result in significant space savings, but it's a performance hit and requires quite a lot of memory.
@ToxicFrog I order 4 - 8TB HDDs. Now if I get another 3 8TB HDDS. I can have two setups. One for daily use and one for backing up. I thought I can just used a program to copy them over to the backup raid
@HornOKPlease IMO, if it doesn't store previous versions it's not really a backup, and any modern backup software will handle that (and deduplication and deltification) for you.
considering the threat model... 1. Fire: if your server/house catches on fire, you're losing all your data if your only copy is on the NAS; it isn't safe for you to try to save some HDDs, get yourself out!! 2. Hacker: if your server is hacked, yes they can more easily wipe a single RAID array than two, but if they enumerate the devices on the system and see a second array (even if it's "offline"), they can bring it online in an instant and nuke it too just to be an a-hole :) 3. Bit flips: ZFS will detect these and correct these really well already
the main purpose of having the "backup" array would be storing prior versions, indeed, to protect against accidental deletion for instance, but it isn't a true backup IMO unless it's offsite
The main use case for local backups is "oh shit, I accidentally deleted ~/.config"; but as @HornOKPlease it won't protect you from lots of other stuff.
For reference, my setup is 4x2TB RAIDZ1 as the main data storage, with a subset of that backed up to a separate 2x1TB Zmirror using bup (although I'm migrating to borg); the contents of the backup array are then copied offset weekly or so.
if you want to really put data "on ice" long term I would suggest AWS Glacier; they're coming out with a high redundancy, WORN (Write Once / Read Never (except for disaster recovery)) storage service called Glacier Deep Archive in early 2019 (we hope) that's $1 per TB per month, so if you had 32 TB of data it would be $384/year, which is probably cheaper than maintaining your own SAN, and many times more reliable
and when you don't have 32 TB of data it's way cheaper than having your own server
paying up front for 32 GB of storage for your local system (and all the time configuring the software, setting up the rig, etc.) only to lose it to fire or flood or theft would be unfortunate
I don't back up everything, a lot of the 8TB array is music/video/installer data that I can re-rip or re-download if I need to. So what gets backed up is (roughly) /home /root /etc /srv and /var/lib on the server and laptop, /home on the desktop, and weekly snapshots of a few websites I manage.
And the backup program compresses and deduplicates all of that, even across machines, so it's stored quite compactly.
I just use Backblaze B2 for my desktop and laptop but I'm considering moving a copy of personal photos from iCloud and Google Drive into Amazon Glacier Deep Archive when it launches; my total irreplaceable data set is under half a terabyte, so that's $6 USD per year for a cloud archival
I will live in an apartment soon. Flood no so much, if you live in a flood zone and don't go boating then you should move. Fires fire enough but you could keep it right by your door or having another setup in your shed. More of a problem are tornadoes.
@ToxicFrog yeah; I've mostly moved to cloud music (Spotify) and cloud video (Netflix) so really my only irreplaceable stuff is pictures of family and my cat and places I've gone, and my password vault
I just used my odd hdd for it and my os drive is my new ssd
@HornOKPlease My friend has 1 megabit down/ second. So its just quicker for me to ship a game to him on a flash drive than it is for him to download it. Lazy devs for not optimizing their games
@HornOKPlease yeah, I need to find a better photo backup solution...my photos are "backed up" to google photos but that doesn't preserve tag/album information.
The Uplay, Origin, and Battle.net clients try to allow at least limited playability with certain games while the download is still in progress. (Sadly, Steam does not have this feature.)
It shouldn't of took him 4 days to get it in the mail. It would have token him like a week and a half to download it. That is if he didn't want to do anything on his net
@MathCubes most modern AAA and MMO games have so much data that putting in a very efficient compression format, like LZMA2, would cause your game to take about 30 minutes to start up, so they store the game data uncompressed, or very poorly compressed, on disk. And content providers like Steam do compress the data in transit across the internet, but not extremely well AFAIK.
@bwDraco You are forgetting something. 1 megabit/second down isn't enough. His ISP just upgraded him from like 750 Kilobits/second down. He has ISDN
I don't get why they can't use low res textures
Heck a game from the time area of a old PC looks better on it than a game in which you lower the settings on. IT just look like a pixelated mess.
I know some games like Xonotic, you can turn off the textures and have solid colors. I don't get why trip AAA games take examples from open source games
@MathCubes it would be very frugal if they would allow you to download only the texture/mesh quality you desire and not all of them; I know a few games that do have high res texture packs as an optional DLC
If a game is bigger than 500 MB than its just too big, and they should offer an micro version
With low res textures
Or none textures and just have a solid color.
When Doom 3 or Quake 3 looks better on a PC than a modern Game with the lowest settings. There is a problem.
I mean like with Intel Igpus
Which a lot of his got
Mordren games in my opinion just sucks
And they can stab their STEAM DRM stuff up their A** too. WHat happens if you have a family? Why should I buy the games for each of my family members that we can all play it for fun.
I know a few older devs who are in disgrace of this new gen of devs about resource management.
This guy that I know, told me that a new dev that came right from college got fired from his workplace cause he didn't think resource management was thing to force on
e.g. the need to set up a client program for most games, and the fact that a number of different clients are now needed, e.g. Steam, Uplay, Origin, Battle.net.
Ubisoft has been having a good deal of success doing this with their latest Assassin's Creed games, though they stumbled badly when they first tried it with Unity.
And the lack of optimization. Just imagine here that they actually optimizatize the game to work with junk hardware and slow nets. How many more people would buy the game now.
@MathCubes Not exactly true, but NVIDIA has done rather anticompetitive things in the past, including releasing middleware that can only be optimized for NVIDIA graphics cards.
Ray-tracing per se is not new, but this is the first time it's been implemented in a hardware-accelerated manner. For professional applications, it can make a significant difference.
@bwDraco I don't know about you but I don't ask anything advice form gamers... You? They think they know everything about hardware but actually know nothing and get all offensive, when you say that overall Vega is better than 1080 architecture for most tasks if you on a budget.
@MathCubes It is indeed true that in general, Vega 64 is slightly better than the GTX 1080. However, the cryptocurrency craze earlier this year made it a non-option for most gamers.
@bwDraco They just see FPS as performance and just can't get warp their head around any other use cause. For example, they don't get that Geforces are way better at Realtime viewing than Quaro cards.
@MathCubes Depends on your application. They often use the same underlying GPU, but NVIDIA restricts certain features to upsell workstation users, and Quadro cards are more thoroughly tested, both at the hardware level and for workstation applications.
For business users, having a card and driver stack that is specifically validated for these applications matters a lot.
The Ryzen Threadripper processors are incredibly powerful, there's no denying that. But there are complexities, like the fact that they're NUMA systems, which can make them perform worse than Intel processors with similar core counts in certain heavily-threaded tasks, and that the WX processors (24C-32C) have two of the four NUMA nodes not directly attached to memory at all.
Linux currently handles this situation far better than Windows does.
Ultimately, there needs to be better software support for these unusual processor architectures. While AMD clearly gives you more bang for the buck here, there's a number of caveats that can degrade performance and prevent the processor from operating at its full potential.
Adjusted the rear exhaust fan curve a bit. Looks like the whole "rad fans pulling GPU heat" problem has been solved.
I'll have to live with a bit more noise, but that's a small price to pay.
I'm currently relying on the motherboard temperature sensor as a proxy for overall system temperature. I know, that's not ideal and it's highly dependent on ambient temperature, but it's as close as I can get to a GPU temperature without relying on a (very inelegant and potentially unreliable) temperature probe.
The other temperature sensors aren't very responsive to the GPU, only the CPU or VRM.
The faster exhaust fan does mean that there is a bit more negative feedback on that sensor, so the maximal temperature readings should be lower than before. This will limit the fan speeds to something sane under normal conditions, while still providing headroom for faster speeds when needed.
It certainly is quieter than the old fan at the same speeds.
And it runs much cooler.
And the radiator fans are not running as hard as they used to be.
Speaking of exhaust fans... I wonder what the speed rating on the exhaust fan on my father's desktop is...
All I know is that it's a 92mm fan connected via the industry-standard 4-pin PWM connector, so I can replace it with a Noctua NF-A9 PWM.
That's far faster than the NF-A9 PWM, so I highly doubt the Noctua fan is a suitable replacement.
(the Noctua fan is rated for 46.4 cfm)
I'm not sure the desktop is going to like a substantially slower fan than the stock OEM part.
It'll do in a pinch should the stock fan fail for whatever reason (it's a "hydraulic bearing", which almost certainly means a hydrodynamic or fluid dynamic bearing, so it should be very reliable), but Noctua needs to make a faster version of their NF-A9.
... And that's why I'm installing Linux on all my personal computers as they get replaced. I don't use the default Windows apps, and I always end up using cross-platform open-source apps, like Firefox, Chromium, GIMP, VLC, etc
