Is there something I'm missing? Are namespaces for VMs or containers? You might as well run some complicated LVM setup instead and do it in software.Last edited by ahrs; 18 November 2024, 08:18 PM.

When you're rolling out massive drive arrays for S3 storage, ZFS nearline arrays, Ceph clusters, etc, then NVME has a lot of benefits over legacy SATA/SAS in both simplifying the connection points, as well as removing some upper limits to how many devices can be attached without needing more controllers.
Similarly, hanging lots of rotational disks off a single 6Gbit controller with port multipliers is absolutely a bottleneck. Again, see the video for how simplified PCIE switching and NVME results in simpler hardware and higher speeds.
The video also talks about what it looks like when every bit of compute and IO is all on the same fabric. For future workloads, having multiple classes of storage, network, GPUs and the like all on the same PCIE/NVME fabric simplifies a lot of problems we have in high end clustering.
Lots of applications for this beyond what a single drive looks like in 2024. NVME looked pretty silly even for flash when it first arrived, because we couldn't hit those speeds back then. But it was clear that it was a necessary change as things moved forward. Limiting things to today's technology is not how the industry works.

still waiting to connect my cd-burner over NVME. why arent there any forward looking standards?

man people here with the memes and missing the point so hard
NVMe requires a new physical connector and form factor over SATA/SAS, also wake me up when an HDD comes close to even touching sata limits, this is just nonsense

When is SATA going away, when is SATA getting replaced, and when is SATA getting a major upgrade that increases the bandwidth?
It's too bad that most motherboards just have one or two M.2 slots.
