I’ve been always puzzled by the strange choice of raiding multiple small capacity M.2 NVMe in these tiny low-end Intel boxes with severely limited PCIe lanes using only one lane per SSD.
Why not a single large capacity M.2 SSD using 4 full lanes and proper backup with a cheaper , larger capacity and more reliable spinning disk?
- tiew9Vii 1y agoThe latest small M.2 NAS’s make very good consumer grade, small, quiet, power efficient storage you can put in your living room, next to the tv for media storage and light network attached storage. It’d be great if you could fully utilise the M.2 speed but they are not about that. Why not a single large M.2? Price.
- riobard 1y agoWould four 2TB SSD be more or less expensive than one 8TB SSD? And also counting power efficiency and RAID complexity?

- foobiekr 1y agoGiven the write patterns of RAID and the wear issues of flash, it's not obvious at all that 4xNVME actually gives you meaningful redundancy.
