You bought the mini PC for the consolidation. One small box on the shelf was going to replace the old tower, the network drive, and the Raspberry Pi that kept falling over, so now it runs Jellyfin for the living room, a Proxmox node or two, Home Assistant, and maybe a small language model that answers questions at three in the morning. You pulled it out of the box, saw it came with a 1TB or 2TB SSD already installed, and moved on to the fun part. On a budget Beelink, GMKtec, ACEMAGIC, or Kamrui box, that bundled drive is often the cheapest component the vendor could legally call an SSD.
The drive that shipped in your mini PC was specified for a single user opening Chrome and saving the occasional file, and the workload you just gave it writes around the clock. Check the drive’s TBW rating (terabytes written) on its spec sheet: under about 600 TBW per terabyte is short for Plex, VM, or camera workloads.
Reviewers keep finding QLC SSDs in budget mini PCs
QLC is the four-bits-per-cell NAND that packs the most capacity into the lowest cost, which is why it suits a low sticker price. Reviewers who opened the GMKtec NucBox K13, KAMRUI Hyper H2, Trigkey S7 Pro, and Blackview MP80 found a QLC drive in the stock configuration. There is no public tally of exactly which drive lands in which box, and vendors swap suppliers between batches (the K13 has shipped with both Crucial and Huawei drives), so treat any specific model as illustrative rather than a promise about your unit. The best-documented example of QLC endurance is the Samsung 870 QVO. It is a 2.5-inch SATA drive rather than the M.2 NVMe stick most mini PCs carry, but it uses the same class of NAND, and Samsung rates it at 360 TBW for every terabyte of capacity: 360 TBW on the 1TB model, 720 on the 2TB, 1,440 on the 4TB, all backed by a three-year warranty. Work that rating back across three years and a terabyte and it lands at roughly a third of a full drive-write per day. For a person who writes a few gigabytes between breakfast and bedtime, that endurance budget lasts for decades.
QLC earns that capacity by trading away write endurance: storing four bits in every cell means each cell wears out after fewer writes. Tom’s Hardware’s running roundup of the best SSDs makes the split plain across its endurance columns: the QLC budget tier sits well under its TLC siblings on rated writes at the same capacity. Newegg’s 2026 explainer on NAND types and write endurance frames QLC as the right pick for “high-capacity secondary storage, media archives, and budget-focused builds.” Hosting virtual machines is not on that list.
A 24/7 server writes far more than a desktop
Write amplification multiplies every write a server makes. Proxmox is the clearest example, and its own community keeps documenting the problem. In one long thread on extreme SSD wearout, the distinguished member Dunuin lays out the math: “Here I got an average of factor 20. So writing 1TB of data inside a VM will cause 20TB of combined writes to the SSDs. So here the SSDs will die 20 times faster because of the exponential overhead / write amplification.” He goes on to explain why a copy-on-write filesystem like ZFS makes it worse: the overheads at each layer multiply rather than add, so a chain of small inefficiencies balloons not to 16x but to 240x (his example layers are 2x, 5x, 3x, 4x, and 2x). A consumer drive has no power-loss protection and little spare area, so it absorbs the full multiplied load.
One user in that thread, Taomyn, ran a pair of Samsung QVO drives and reported, “After about 9-10months mine are at around 12/13%.” Project that line forward and a consumer QLC drive on a busy node burns a meaningful slice of its life every year. Another, xlemassacre, reported two Kingston NVMe drives at 36 percent after a single year, though the user later traced most of it to a runaway script hammering the Proxmox API and writing nearly 2TB a day, which they eventually cut to about 250GB.
Plex and Jellyfin add their own write load. Every time the server transcodes a file it did not have in the right format, it spills thousands of temporary chunks to disk, and unless you tell it otherwise those chunks land on the same drive that boots the OS. A surveillance recorder writing camera streams around the clock, a ZFS pool keeping its journal, a database flushing its write-ahead log: each of these is a steady drip onto a drive that was rated for a trickle, and each is normal behavior for an always-on self-hosting box.
TBW per terabyte, and how much each workload needs
TBW is the manufacturer’s promise of how many terabytes you can write to the drive before the warranty stops covering wear. Divide it by the drive’s capacity and you get TBW per terabyte, a clean figure you can compare across any two drives regardless of size. Read it against your workload.
The NAS-drive vendor KingSpec offers one widely-cited rule of thumb in its best-SSD-for-NAS guide. It is a vendor blog rather than an industry standard. By that guide, light home NAS and file backup are fine on “300 to 600 TBW per TB,” photo and video storage and Plex streaming sit closer to “600 to 1000 TBW per TB,” and heavy multi-user work like surveillance and virtualization calls for “1500+ TBW per TB,” with the guide suggesting at least 600 TBW per terabyte as a baseline for anything you would call a NAS drive. A consumer QLC drive at roughly 360 TBW per TB sits inside the lightest band, below the guide’s 600 baseline for a NAS drive, and short of every band above it.
Power and cooling also shape a 24/7 box: see what a mini PC costs to run around the clock and whether fanless or active cooling fits the workload. Endurance decides how long the storage inside it survives that duty, and a mini PC’s own spec sheet usually names only the drive’s capacity, not its TBW.
2026 QLC is faster but no more durable
Newegg’s explainer highlights SK Hynix bringing 321-layer QLC into mass production with up to 56 percent better write performance than the previous generation. Those are throughput gains. The same piece offers no jump in rated program-erase cycles or TBW to go with the speed, and the published endurance numbers on shipping QLC drives have not moved to match TLC. Compare drives by TBW, not by layer count or speed claims.
Swap to a TLC drive rated 600 TBW per TB or more
Above the lightest tier, the extra cost of a TLC NVMe drive buys a large jump in rated endurance. A Samsung 990 Pro is rated at 600 TBW per terabyte; a Crucial T705 and a WD Black SN850X land at the same 600; and the NAS-targeted WD Red SN700 is rated in Western Digital’s product brief at 2,000 TBW for its 1TB model, the kind of margin a virtualization host wants (the 2TB is rated at 2,500 TBW and the 4TB at 5,100 TBW). Against a 360 TBW per TB bundle, even the mainstream TLC options buy you most of a doubling, and the 1TB NAS drive buys you more than five times the headroom.
| Drive | Class | Rated TBW per TB |
|---|---|---|
| Samsung 870 QVO | Consumer QLC (reference) | 360 |
| Samsung 990 Pro | Mainstream TLC | 600 |
| Crucial T705 | Mainstream TLC | 600 |
| WD Black SN850X | Mainstream TLC | 600 |
| WD Red SN700 | NAS TLC | 2,000 (1TB), about 1,250 (2TB and 4TB) |
For a media library or a single-purpose file server, a mainstream TLC drive at 600 TBW per TB lands you at the bottom of the right tier. For a box that runs virtual machines, containers, or camera recording, reach for the NAS-class drive; the 1TB WD Red SN700 is the only drive in the table that clears the 1500+ band, and its larger sizes land near 1,250. This is a separate question from the SSD and DRAM price climate that has made every drive cost more this year.
The mini PCs that make the swap painless
Buy a box you can open and upgrade, ideally one with more than one M.2 slot, so you can keep the operating system on one drive and put the write-heavy pool on another. With the logging and swap fixes below, a boot drive that carries only the OS can stay on whatever the box shipped with, while the VMs, the camera streams, or the transcode scratch get a high-endurance TLC drive sized to the tier they fall in. These three machines make that easy at three very different scales.

If you cannot swap yet, make the bundle last
For Plex and Jellyfin, the biggest single lever is moving transcoding into RAM. CoreLab’s Plex optimization guide describes transcoding as generating thousands of temporary files and calls leaving them on the OS drive a “speed vs. lifespan” trade-off that leads to massive SSD wear. It points users with 32GB or more of memory to mount the transcode directory in RAM, where the writes cost the SSD nothing. On a Docker setup that means pointing the transcode path at shared memory and giving it room; on bare metal it means setting the transcoder’s temporary directory to a RAM-backed mount.
Proxmox has its own well-worn mitigations, collected in a thread on reducing SSD wearout. User readyspace gives the blunt version: “Move logs, swap, and RRD data off the SSD or into tmpfs/ramdisk to cut small writes.” User cryptonym64 adds a specific tool: “Use log2ram. That virtually eliminates the minute logging entries that eat SSD.” It buffers logging in memory and flushes it on a schedule instead of writing every line straight to flash. None of these turn a QLC bundle into a NAS drive, but together they can cut the write volume enough to buy you the months you need before the replacement arrives.
Whatever you run, check the drive you already own before you trust it with the job. Most NVMe drives report a “Percentage Used” value through smartctl -a, an estimate of how much of the rated endurance is gone. Read it once a month for the first few months under your real workload. If it barely moves, the bundle is fine and you can leave it alone. The value counts up toward 100, so the monthly climb tells you how long the rating lasts: at one point a month it runs out in a little over eight years, and at three points a month in under three. If that projection ends before you plan to retire the box, replace the drive with a TLC model from the table above.
