Search results for query: QLC

Lots of threads on this forum about problems with QLC SSDs including that particular one. EDIT: My advise would be to use the search.

That's what I tried to say before. Consumer SSDs (like your QLC drive, which is terrible for VMs by the way!) can lose all data easily on unexpected power loss as it moves "data at rest" around (including the drive's internal data allocation tables). I cannot explain that, sorry. There have...

...time? I am not using ZFS for boot, i have ZFS on my second 1 tb SSD, but the OS is on the main drive (a 128 GB M2 SATA III). Yea, i know what QLC is and my Crucial BX500 is indeed QLC. That's why i want 3 nodes in a cluster with a Raid 5 (3 ZFS pools for each secondary 1 TB SSD from each...

Please make sure not to buy drives with QLC flash memory (search for QLC on this forum). There are threads on this forum that describe things you can do. But they are not supported, can break things and will make troubleshooting much more difficult. Maybe use KVM/QEMU directly via libvirt...

Don't use one with QLC flash memory but get something with good endurance like an enterprise SSD with PLP for your VMs. Proxmox VE itself can run fine from an HDD (just make sure it is CMR and not the new SMR kind). Proxmox logs a lot which is not great for some SSDs. So if you already have an...

...way easier (except if this unofficial pve spin requires something like this) sd cards are way slower than a cheap ssd (don't use ssd's with QLC memory - really bad performance), especially iops which are the most important metric for virtualization or containers and with a nvme ssd adapter...

Danke @IsThisThingOn . Ich werde mir die 990Pro holen. Generell finde ich den markt gerade kompliziert. Habe auch nach einer 2,5" SATA mit MLC oder SLC geschaut aber da finde ich gar nichts. Ich finde nur QLC in großen Mengen. Wo kauft man sinnvolle Sata SSD´s? Hast du da einen Tipp?

V-Nand ist Marketing Sprech für TLC. TLC ist sicher besser als QLC, aber ist auch kein MLC oder SLC. Für den Preis bekommst du auch eine 990 Pro. Für Zuhause, nix besonderes ausser kein QLC. Bestenfalls ein Mirror mit einer anderen Marke / Controller. Dann kann auch eine Ausfallen. Gerade...

I stopped reading here and suggest your search the forum about QLC drives: https://forum.proxmox.com/search/8337402/?q=QLC&t=post&c[child_nodes]=1&c[nodes][0]=16&o=date

It's the same with QLC and SMR drives: nobody buys them after searching the forum, always the other way around... Proxmox is based on Linux and you need to research support before buying any hardware. I have no personal experience with Thunderbolt/USB4, so maybe it still works for your use case...

...man jede einzelne Container einzeln aufwählen kann. (Glaube unter PVE oder datacenter) @showiproute Ich glaube, bei meiner Anwendung kam die QLC NVMe nicht in die Knie. Das passierte vor allem nachts, wenn eigentlich nichts allzu großes los war. Jedenfalls hätte das nicht zu dieser Art von...

...nur machen, wenn du in deiner alten Proxmox Installation irgendetwas Spezielles eingestellt hast. Hast du dein Proxmox einfach so genutzt, musst du das natürlich nicht machen. Als Info noch: QLC-SSDs sind nicht empfehlenswert, da die recht schnell in die Knie gehen, wenn es zu Lastspitzen kommt.

...laut Logs. Das ganze System hat sich deshalb aufgegangen und ich musste einen Hardboot über den Power Knopf jedes mal machen. War ne Kingston NV2 QLC Platte. @UdoB Danke. Das merke ich mir für spätere Notfälle. Das Problem ist, dass die alte NVMe so langsam wird und nahezu vollständig...

...fine on HDD(s) as it writes a lot but does not need much read performance. For VMs, you want SSDs for the much higher IOPS. Never use drives with QLC flash memory and if you can use (enterprise) drives with PLP. Go for enterprise (SATA) SSDs with PLP if you can. The endurance and sync write...

Would i bee okay for performance increace to use ssd with TLC cache? Does it need to be PLP? eg. Samsung 990 Pro

Enterprise drives with PLP. You can use the same search for QLC on this forum to find lots of recommendations (which always follow after people accepts the disappointment).

Do you have drive recomendations? M. 2 or Sata SSD

Then don't use the ct2000p3pssd8 or any other drive with QLC flash memory. They do get that slow (but you probably won't believe me, so use =1&c[nodes][0]=16&o=date']the search).

That one uses QLC flash memory, which can become slower than an old HDD when doing sustained writes. There have been previous problems reported with it (but it might be with ZFS). I'm not sure about that old model Those are pretty old models but at least MLC (no experience at all).

...Tech Tip benchmarks - they're great for gaming machines, but not focused on servers instead look for IOPS, DWPD, and MLC or TLC (the Evos have QLC which fails quickly) buy MUCH bigger than you'll need - so that you get more wear-leveling enterprise drives are more expensive (and longer)...
