...ausgewiesen haben und nach 3 Jahren Nutzungsdauer einen Fehler melden und getauscht werden "wollen". Bei SSDs ist es ähnlich, keine Consumer SSDs, nur welche mit TLC (* oder Besser), DRAM Cache, PLP und hoher TWB. Z.B. Kingston DC600M, SATA # https://geizhals.de/kingston-dc600m-v130517.html

...an unused Crucial MX500 SSD attached (sde), which I would like to migrate my Proxmox to while I acquire a low capacity enterprise grade SSD with PLP. Questions: What would be the best way move Proxmox into safe area e.g. to a new MX500? I see options like 'Move storage', but also I can...

...unter konkurrierender Last über längere Zeiträume. Genau dort unterscheiden sich Consumer- und Enterprise-SSDs (QoS, Garbage Collection, PLP etc.). Genau diese Situationen (GC, Flush, konkurrierende Writes) treten in kurzen synthetischen Tests typischerweise gar nicht oder nur unzureichend...

...30885445632 | 7540392 | 490.79 | 125642.39 | 0.865 | 17.771 Also. "Consumer-SSD" sind so schlecht nicht. Die SN700 haben jetzt in 4 Jahren gerade mal 16% verwirkt. Das reicht also für weitere 20 Jahre. :) Was ich nicht habe, ist PLP. Da verzicht ich halt, genauso wie auf ECC.

Nun ja SSDs mit plp können rein technisch Dinge, die Consumer-ssfs nicht können, das wurde auch mal sehr erschöpfend hier im Forum ausdiskutiert: https://forum.proxmox.com/threads/powerloss-protection-plp-mythos.157003/ Was ich nicht überzeugend finde: Aus der privaten "hier geht es"-Erfahrung...

...with consumer ssd/nvme with zfs && ceph. you can look at the forum, the same question come back again && again with same problem. and th response is still the same: don't use consumer ssd/nvme without plp. note that your are going to burn them fast too because of write over-amplification.

vzdump onto the same disk? Snapshot or large sequential writes should not be a heavy load. I would say yes. No, but it would be far from the first time consumer SSDs have problems. Especially the ones that only buy Phison controllers and slap on a buggy firmware. What @spirit was tryint to...

Yes, but the same principle applies here as with wear levels. If many users access IOPS-intensive applications on your server simultaneously, this will likely have a significant impact. However, on my home server with Nextcloud, Plex and a few web apps, which my girlfriend and I use, you won't...

When people recommend PLP it's often not directly about PLP itself but about the increased (sync) performance that tends to come with it. See this thread in the german section where it's discussed: https://forum.proxmox.com/threads/powerloss-protection-plp-mythos.157003/ Compare the...

...of that. To get back to your initial question "How to reduce wear out" the correct answer IMHO would be: Don't worry! Others here recommended PLP drives, but in reality most workloads are perfectly fine with just good consumer drives. I have been running a mixture of cheap Kingston DC1000...

(small reminder: don't use zfs on consumer ssd/nvme . they can't handle a lot of fsync because they don't have a PLP/powercapacitor), and zfs do a lot of sync. It's really like 200~1000 iops max with this kind of drive.

...ZFS are a) some higher wearout = the SSD won't last as long as with LVM/ext4 and b) slower performance because of more write-activity. (And no PLP which would allow delaying the actual write...) The required amount of RAM for ZFS is not as high as very often stated in the past. Especially...

I get that its not great for VMs but the IT here used to have the servers on the baremetal with no redundancy for the data. I went with proxmox and RIAD Z1 because of redundancy. I can do hardware RAID as all the hosts are able to but went with software (Proxmox) RAID out of convenience of doing...

RAID5 (with BBU) is almost, but not quite, entirely unlike RAIDz1 (with drives without PLP). RAIDz1/2/3 is not good for VMs but can give you more usable storage (but padding can be terrible for space): https://forum.proxmox.com/threads/fabu-can-i-use-zfs-raidz-for-my-vms.159923/#post-734639

Use consumer SSDs at your peril. They fail and fail spectacularly. Only real solution is enterprise SSDs with PLP (power-loss protection) and for endurance.

...That said... I need to mention the problems with (too) cheap disks. It is highly recommended to use "Enterprise Class" devices with PLP. (For both speed and endurance.) If that is a problem for you should know what ZFS gives you in exchange for this "problem"...

A hardware RAID controller Battery Backup Unit (BBU) can cache sync writes and that might indeed help. (Or replace the SSDs with ones that have PLP.) ZFS RAIDz1 is a poor choice for VM as the IOPS are much lower then using a ZFS stripe of mirrors. Maybe you should redo your ZFS pool for better...

War das eine "gute" NVMe (mit PLP; eher unwahrscheinlich) oder etwas billiges? Preiswerte NVMe/SSD neigen im PVE Kontext dazu, nicht sehr lange zu halten. Bitte markiere diesen Thread als "Solved", man kann "oben" den Titel editieren.

I’m not going to say I’m an expert on the drive but per https://www.techpowerup.com/ssd-specs/samsung-9100-pro-1-tb.d2318 it does not have PLP. Assuming they’re similar. The Proxmox disk page shows % wear in the far right column if you’re concerned about disk life.

Thank you thanks you i appreciate the reply. If i remember correctly it wasnt too bad until i started adding multiple vms. WOuld any consumer grade drive work reasonably well ? the cost differential is a bit steep when going to enterprise grade drives
