Is the disk NVMe on a Ryzen dedicated server?

On SistemDC Ryzen dedicated plans the OS/data row is NVMe. The 5700G has a single disk; the 5950X and 9950X have 2×1 TB; Business ECC has 2×1 TB Gen5 Samsung 9100 Pro.

Should I put the two NVMe drives in RAID-0?

RAID-0 gives capacity and sequential speed; the array is gone if one disk fails. Separate mounts for OS and data, or RAID-1, are more readable for most production.

Does Gen5 NVMe speed up every job?

The ceiling rises for large sequential copies and media caches. Small random I/O is usually limited by the queue and the CPU.

Does NVMe replace backups?

No. A fast disk is not a backup. Snapshots and off-node copies are planned separately.

NVMe SSD Guide for Ryzen Servers

On a Ryzen dedicated server the bottleneck is usually not the cores but the disk queue: world saves, Docker layers, media cache, the PostgreSQL WAL. This article is not specific to NLE/rendering; that is covered separately: Ryzen render server. Here you will find how NVMe is positioned on a dedicated node, a single disk versus 2×1 TB, software RAID and the Gen5 ECC plan. Hardware list: Ryzen server options.

Short answer: All SistemDC Ryzen dedicated plans use NVMe; there is no HDD world/OS row. The 5700G has a single disk (500 GB or 1 TB); the 5950X and 9950X have 2×1 TB. Business ECC has 2×1 TB Samsung 9100 Pro (PCIe Gen5). RAID-0 gives capacity, but everything goes when one disk fails. An OS + data split is more readable for most teams.

Why NVMe on Dedicated?

SATA SSDs lag behind NVMe in random I/O; HDDs cut into tick/commit for game worlds and databases. NVMe shortens the queue the CPU waits on. This is not a “Cinebench +20%” claim; the drop in iowait is felt or not depending on the job.

Endurance (TBW) depends on the manufacturer's model. Consumer Gen5 drives quote high sequential speeds; a 24/7 random-write profile is not the same class as enterprise U.2/U.3. Backups (snapshots, off-node) are a separate matter from NVMe speed.

SistemDC Ryzen Disk Rows

Plan	Disk (live list)
R7 5700G 32 GB	500 GB NVMe
R7 5700G 64 GB	1 TB NVMe
R9 5950X	2×1 TB NVMe
R9 9950X Non-ECC	2×1 TB NVMe
R9 9950X Business ECC	2×1 TB Gen5 Samsung 9100 Pro

The 9950X platform offers PCIe 5.0; the 5700G/5950X are the AM4 generation. Chip summary: Ryzen 9 9950X. Model map: 2026 dedicated guide.

Two NVMe Drives: RAID-0, RAID-1 or None

Separate mounts: nvme0n1 = OS + logs, nvme1n1 = VM disks / media / world. When one disk fills up the other lives on. Backups are still a must.
Software RAID-0: A single 2 TB volume, and sequential speed may increase; the array is gone if one member fails. “RAID-0 for speed, no backups” is the production anti-pattern.
RAID-1: Capacity stays at 1 TB, mirrored against a member failure. Writes go to both disks. In SistemDC's rows the “hardware RAID card” is listed as Software on the 5700G and as motherboard RAIDXpert2 on the higher plans; the real policy is your choice of mdadm/ZFS.

What Does Gen5 (9100 Pro) Change, and What Does It Not?

The Samsung 9100 Pro is the manufacturer's PCIe 5.0 NVMe-class consumer drive. We are not copying the sequential read/write marketing figures here and saying “your server does X GB/s”; real speed depends on queue depth, the CPU, thermals and the file system.

Gen5 gives a higher ceiling than Gen3/4 for large media caches and heavy sequential copies. Small random 4K (databases) is usually limited by the queue and the CPU; there is no “I bought Gen5 and TPS doubled” claim in this article.

ECC memory and the Gen5 disk come together in the same Business plan; one does not replace the other. ECC: Ryzen ECC RAM.

Frequently Asked Questions

Does Ryzen dedicated come with an HDD?
In the live Ryzen dedicated list, the OS/data row is NVMe.

Should I combine the 2×1 TB?
RAID-0 for capacity; RAID-1 or separate mounts + backups for resilience. There is no default “combine”.

Is Gen5 a must for rendering?
It is useful for large proxies/caches; it is not magic. Workflow: the rendering article.

What happens when the NVMe wears out?
The SSD's TBW runs out, latency rises or the device drops to read-only. Monitoring (SMART) and backups are your operation.
