Best Enterprise SSD Setup for Sustained Writes in a Virtualization and Backup Server?

[tanneredward315]

Hi everyone,

I’m currently upgrading the storage setup in one of our virtualization and backup servers and I’m trying to avoid the performance drop that can happen during long sustained write workloads.

The server handles several VMs, scheduled backups, database exports, and occasional large file transfers. During heavier backup windows, we can easily write a few hundred GB continuously, so short burst benchmark speeds aren’t really what I’m interested in.

My main concern is sustained performance once the SSD cache fills up. I’ve seen some drives perform extremely well for the first few minutes and then slow down significantly during longer transfers.

I’m also trying to decide whether it makes more sense to use enterprise NVMe drives directly in the server or a RAID based SSD configuration. Reliability, endurance, thermal behavior, and consistent write speed matter more to me than peak benchmark numbers.

For anyone working with similar server storage setups:

How much attention do you give to sustained write speed versus advertised sequential speed?

Would you prioritize higher endurance enterprise SSDs over faster consumer NVMe drives for this type of workload?

Does anyone have experience with thermal throttling when multiple NVMe drives are installed close together in a server chassis?

I’ve been comparing different enterprise storage and server hardware options from ORM Systems while planning the upgrade:

I’d be interested to hear what has worked well for others running virtualization, backups, or other write heavy workloads.

Thanks.

Thank you for your post,

For the type of workload you're describing, you seems to be focused on sustained write performance, endurance, and thermal design. However, without knowing the exact server platform, form factor, backplane, controller, cooling design, and workload profile, it's difficult to recommend a specific SSD or storage architecture. Since you're planning a new deployment, we would suggest working closely with your system vendor to validate compatibility and build a solution tailored to your performance, capacity, and availability requirements.

In general, enterprise SSDs are a better fit than consumer SSDs for virtualization, backups, database exports, and other write-intensive workloads because they are designed for predictable latency, higher endurance, and 24x7 operation.

Within the Solidigm portfolio:

• D7 Series SSDs are our flagship performance-focused and specialized product family, designed for demanding enterprise workloads.
• D5 Series SSDs prioritize capacity, density, and cost efficiency for large-scale storage environments.

If your primary goal is maximum performance, our newest PCIe 5.0 x4 models D7-PS1030 and D7-PS1010 are worth considering. Just keep in mind that achieving their full performance potential requires a platform capable of supporting PCIe 5.0, adequate cooling, and an overall system architecture designed for those speeds.

You can compare several Solidigm enterprise SSDs side by side using our comparison tool: https://www.solidigm.com/content/solidigm/us/en/products/compare.html

One final note: when multiple NVMe drives are installed close together, adequate airflow becomes extremely important. Even the fastest SSD can see reduced performance if the server chassis cannot provide sufficient cooling during sustained workloads.

Hope this helps, and good luck with the upgrade!
