Squazz

I was thinking the same thing. But, when looking up excactly that series, I found this reddit post: https://www.reddit.com/r/DataHoarder/comments/2vxboz/comment/cp6umlc/?utm_source=share&utm_medium=web2x&context=3 As soon as sustained writes gets past 30GBs the write speed tanks (people say it flattens out at 27MB/s. Which it always will when it is introduced to Unraid. So, I am still curious what the actual experience is by the people who are using these Archive drives. And, wonder if anyone has ever replaced an existing drive with a archive drive?

So, I've seen that quite a few people are running Seagate Archive drives, and seem to be happy with the drives. But, that is confusing me. Won't the fact that they are SMR drives be quite a problem when replacing a dead drive, or just introducing them to the array? Right now I have 40Tb (8x5TB ST5000AS0001) worth of drives sitting on a shelf, as I don't want to introduce them to my UnRaid array if they turn out to be quite a hassle to work with. I tried to replace a 3Tb WD RED (WD30EFRX) with one of my Archive drives, and it quickly went from acceptable to 10MB/s. For a 5TB drive, 10MB/s is never gonna cut it. At that speed, they are probably never gonna get introduced to the array before another drive dies. So, in the end my question might be. What am I doing wrong? If people are happy with their 8Tb Seagate Archive drives, then why does it seem that I am getting speeds as 10MB/s?

Buying new harddrives just for the reduction in power, seems to not really be worth it. At least here in Denmark We are talking a payback time of at least a decade, when looking at powerdraw exclusively It's a nice bonus. But not something I'd buy new drive for

That's a fair point! Which is also what is making me consider if I should just go with 8Tb 7E8 drives instead. My signature is updated now Good to hear about your experience, and a fair point about the 2hr/day is also viable, as long as it is done.

I feel there's beginning to be a consensus. I'm propably gonna end up with buying 2x Seagate Exos X16 ST16000NM001G 16TB drives, that's where I get most space for the money. And it also seems that parity checks is not that big of a problem with drives in the sizes of above 10Tb

I guess I'll go with the 16Tb drives then I'm considering removing one of my two parity drives, and then just go with a single 16Tb parity drive Sounds interresting, I'll give it a look Interresting that you only see 26 hours for a parity check on the 16Tb drives. If one doesn't feel the impact of the parity check, a monthly check might be OK. @DMills could the reason you don't see an impact be that you have a big cache? Personally I don't have that big a cache as I'm only running SSDs as my cache

Hi I have a bunch of WD Green 3Tb drives. And I'm beginning to run out of space (both physical in the computer case, and on the shares) I'm considering buying new Seagate Exos X16 16 or 14 Tb drives. But, are they gonna be too big? I'm considering the parity checks. Right now it takes me about 8 hours for my 3Tb drives. If it's gonna tke me 5,5 times as much time with 16Tb drives, we are talking 40+ hours of parity checking. That's almost two days where I will see degraded performance on my shares. Right now I do parity checks every month. That doesn't seam feasable with a 2 days parity check. What is the experience from other people? Are 16Tb drives too big? How often do you do parity checks with so large drives? How long does it take to take to do parity checks of drives of this size? My main fear is data degradation through bitrot or the like.

I have 2 5Tb disks as parity, and duing a parity-sync they both ended in an error-state. I've attached SMART reports for both. On of the drives I understand if is dying/dead. It seems it has some errors, and they are probably worsening. The other drive on the other hand, I don't understand why ended in an error-state. I'm hoping someone can help me figure out why my drives ended in an error state. Crossing fingers that I'll be better to read the reports after I've gotten some help on this event. nas-smart-20220309-1900.zip nas-smart-20220309-1853.zip nas-diagnostics-20220309-2042.zip

Oh, I'm gonna try it out I was just wondering why the official recommendations said not to use that setup, if that is the most stable setup

Yup, tried that. When first the VM gets in the "wont boot" state, nothing can save it.

Interresting, can you find a concrete place where this is recommended? As far as I know it's only recommended for Linux & MacOS?

For the past 3 years, I've been daily driving a Windows VM (see link for topic around my setup) I've had some problems here and there, but this week everything just went heywire. I've started to get currupted boots, every, single, time. After tinkering with it for the past week, i've tried setting up a bunch of new VMs today. Fethcing the latest ISO for Windows, and basing my VMs on that. After install all of the updates, and rebooting, the problems starts. Sometimes the system just halst after trying to start up windows for half and hour. Other times it goes strait to the blue screen, telling me that bootup is corrupted, and needs to be repaired (which I'm never able to do). I'm trying to set up the machine with CPU Mode: Host passthrough 10 logical CPUs pinned (and isolated) Initial Memory: 30720 Max Memory: 30720 i440fx-5.1 OVMF USB 2.0 Primary vDisk Location: auto: /mnt/user/domains/Windows 10/vdisk1.img Primary vDisk Size: 110Gb Primary vDisk Type: Raw Primary vDisk Bus: VirtIO Passing through: - 1070ti - 1070it soundcard - onboard soundcard - Stubbed USB 3.0 controller: AMD Family 17h (Models 00h-0fh) USB 3.0 Host Controller | USB controller (30:00.3) The share "Domains" is set to "Prefer : Cache" My Cache pool is a single 500Gb Sata SSD: Samsung_SSD_860_EVO_500GB_S4XBNF1MA02769A - 500 GB (sdb) unRaid version: 6.9.2 I'm running the latest BIOS version for my motherboard My Hardware CPU: Ryzen 7 1700 (65W) Motherboard: MSI MS-7A33 motherboard Ram: 16GB (2x 8GB 2400Mhz) + 32Gb (2x 16GB 2400Mhz) Raid drive: LSI 9201-8i GPU: 1070ti What can I provide of information to help you help me? I'm kinda stuck, I don't know what to do from here. Right now, I'm unable to use unRaid to host Windows VMs

Can it be true that I cannot create read-only users? I created users in unRaid and set the description as needed. But even though they are set as only having read-access to a given share, they still have write access?

@Josh.5 unfortunately I don't really play games anymore. It's primarily work and video-consumption that's done on my computer. I've been trying to play some CS:GO, but it seems that FPS caps at 100FPS, and I too have experienced micro-sutters from time to time. In the end CS:GO competitive was a no-go though a VM for me. So I have a bare-metal machine for that. Passing though the entire SSD, and the entire USB controller seems to give the best results too.
