Actual speed when using NVMe SSD in NAS: Is it worth the advertisement? - RoseBL - 09-24-2025
Hello everyone, I am planning to buy a NAS with a slot that supports NVMe SSD for cache or primary storage. The manufacturer offers very high read/write speeds (e.g.,3,500 MB/s), but I want to ask from practical experience:
With popular NVMe SSDs like Samsung 970 Evo Plus or WD Black SN750, what percentage of the actual speed when running on the NAS will be compared to the manufacturer's advertised specifications?
What factors have the strongest influence on speed reduction (e.g., NAS motherboard type, network protocol, RAID configuration, firmware)
Are there any NAS that support NVMe SSDs well to maximize their performance? If so, give me some examples to compare.
Thanks, everyone, for sharing in advance!
