    I'd just get a large external HDD here. Size don't really matter probably go for something like 16TB+ here.

    If you're mixing and matching drives. SHR is the only way. SHR2 allows for 2 drives to fail and offers the same storage as RAID 10 in a 4 bay NAS. In a 6 bay NAS, SHR2 gives you another drive of capacity, but you can still only loose 2 drives.

    Electronics Wizardy reacted to manikyath in Synology NAS RAID 10 question   
    it's generally not recommended to mix different drive models in one RAID array, because even if the specs on paper are the same, they may have very different write behavior.
     
    besides that, any reason why you dont use RAID6? that would let any two drives in the array conk out rather than just 'singles out of a pair'.
     
    commentary aside, i found this bit on synology's website:
     
    so they'd make a RAID1 out of bay 1+2, and another RAID1 out of 3+4, and then stripe 12 + 34.

    Electronics Wizardy got a reaction from aisle9 in Could desktop PSUs handle screen power ?   
    Its possble apple has done it in the past with ADC, but there are a lot of problms so no one uses it.
     
    As far as making monitors cheaper by removing the PSU, this probably won't happen unless every device has the power adaptr built in. And a lot of device that can connect to displays like phones and laptops aren't really ready to provide extra power. You could only have it for lower power displays but there its annoying which display needs power and which has it included.
     
    I doubt this would be a win. Extra large PSUs only really make sense if the monitor is using it. And how much extra power? A basic office monitor is like 20-40w, but a few HDR displays could be 1000w+, so this makes it much more complex.

    Electronics Wizardy got a reaction from Andrewtst in Filmy 720p czy 1080p dla rozdzielczości 1366 x 768   
    Typically downscaling videos will look better, so go for the highest resolution you can, in this case 1080p.
     
    I is interlaced. Basically half the fame changes, then the other half. This is basically a relic of NTSC and other anologue video standards, and almost never used with digital video these days.

    Electronics Wizardy got a reaction from Needfuldoer in Moving countries, changing power cable   
    Yea that cable will work fine. SInce you got 240v, your moving 4-5amps max, so you basically any cable will be fine here.

    Electronics Wizardy got a reaction from RONOTHAN## in Moving countries, changing power cable   
    Higher voltage = less current for the same power
     
    Current is what makes cables warm and drop voltage, which is the main limit for current. So higher voltage lets you use thinner cables for the same amount voltage drop and thermal issues.

    I was working on the computer and it just stopped. Didn't work when I turned it back on. Tried a different GPU in the system and it worked fine, the GPU also didn't work in a different rig.

    Thanks for you answer. From what I found on internet, there is only two 3.5" slots in the case. However there is two 5.25" bays that could be converted into three 3.5" bays. I just need to check the number of sata ports on the MB.

    Does it have more drive bays if you want to add more drivers later on? 
     
    I'd probably get bigger drives as I find 4TB fills up fast, but really depends on your use. 
     
    Otherwise seems fine here.

    4090 is not worth its current price imo, and 5000  series may  come out before end of year
    In the meantime if your old card doesn't cut it I'd get a "cheap" high VRAM card like the 6800XT, 6900GRE or 6900XT

    What are you using it for?
     
    Make sure it has a HBA, not a raid card.
     
    I'd probably keep the current CPUs for now if it was me.

    NAS drives will still reallocate bad sectors, but they have a different time out to keep raid cards happy. 
     
    If the drive works I wouldn't touch it. Keep backups of the drive so your data stays safe. No drive is perfect, and any drive can fail at any time with no warning.

    Electronics Wizardy got a reaction from filpo in what does more ram do   
    More ram lets you have more programs and other data in ram. 
     
    Ram doesn't affect boot time, and more ram can make it slightly slower to boot as it has to initalize all the ram. 
     
    The system limits the ram, not the Type, I know of systems with > 1TB of DDR3 ram.

    Electronics Wizardy reacted to wanderingfool2 in Why is the industry trying to push 8K instead of 6K   
    The difference between 8k and 4k is doubling, it means easily scaling of screen resolutions without any artifacting.
     
    If you lets say tried putting 4k content on a 6k display you have a 1.5x ratio.  That means you will have essentially pixels where you need to do something like make up the color between or repeat it.  That can create visual artifacts that can be slightly off-putting even if you don't necessarily notice it.
     
    Overall as well, it's a lot easier to sell a phrase like 8k than it is to 6k because "6k" doesn't sound as impressive compared to "4k"

    Electronics Wizardy got a reaction from MiszS in Sandboxing   
    This really depends on what you mean by sandbox. The sandbox feature in Windows is a full on VM using Hyper-v under the hood.
     
    Its hard to say much more without details about the threats your worried about on this drive.
     
    If you already scanned it with anti malware on your system, the chance of malware is pretty low, and if there was malware on the drive that would run automatically, it likely would have ran by now.

    Electronics Wizardy got a reaction from Needfuldoer in 16GB optane for proxmox boot drives?   
    I have done this exact setup, and it works fine.
     
    But the 16GB optane drive really don't have that much endurace ~180TB, so a normally ssd will be pretty simmilar. And the optane drives will go read only at about 10% more than the rated writes. 
     
    Proxmox only writes about 10TB a year on the boot drives, so a standard ssd should work fine.
