I'm curious if it would make sense for write caches in RAM to just include a CRC32 on every block, to be verified as it gets written to disk.
Don't you have to read that data into RAM before you can generate the CRC? Which means without ECC it could get silently corrupted on the way to the cache?

The 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.
Would four 2TB SSD be more or less expensive than one 8TB SSD? And also counting power efficiency and RAID complexity?

Your link is talking about leaving drives unpowered for years. That would be a very odd use of a NAS.
True, but it's still concerning. For example, I have a NAS with some long-term archives that I power on maybe once a month. Am I going to see SSD data loss from a usage pattern like that?

#134Are there any mini NAS with ECC ram nowadays? I recall that being my personal limiting factor
Minisforum N5 Pro Nas has up to 96 GB of ECC RAM https://www.minisforum.com/pages/n5_pro https://store.minisforum.com/en-de/products/minisforum-n5-n5... no RAM 1.399€ 16GB RAM 1.459€ 48GB RAM 1.749€ 96GB RAM 2.119€ 96GB DDR5 SO-DIMM costs around 200€ to 280€ in Germany. https://geizhals.de/?cat=ramddr3&xf=15903_DDR5~15903_SO-DIMM... I wonder if that 128GB kit would work, as the CPU supports up to 256GB https://www.am…
Re: Mini NASes marry NVMe to Intel's efficient chip
#135While it may be tempting to go "mini" and NVMe, for a normal use case I think this is hardly cost effective. You give up so much by using an all in mini device... No Upgrades, no ECC, harder cooling, less I/O. I have had a Proxmox Server with a used Fujitsu D3417 and 64gb ecc for roughly 5 years now, paid 350 bucks for the whole thing and upgraded the storage once from 1tb to 2tb. It draws 12-14W in normal day use an…
Re: Mini NASes marry NVMe to Intel's efficient chip
#136NVMe NAS is completely and totally pointless with such crap connectivity. What in the WORLD is preventing these systems from getting at least 10gbps interfaces? I have been waiting for years and years and years and years and the only thing on the market for small systems with good networking is weird stuff that you have to email Qotom to order direct from China and _ONE_ system from Minisforum. I'm beginning to think…

4 small drives+raid gives you redundancy.
I'm hopeful 4/8 TB NVMe drives will come down in price someday but they've been remarkably steady for a few years.

Re: Mini NASes marry NVMe to Intel's efficient chip
#139Intel N150 is the first consumer Atom [1] CPU (in 15 years!) to include TXT/DRTM for measured system launch with owner-managed keys. At every system boot, this can confirm that immutable components (anything from BIOS+config to the kernel to immutable partitions) have the expected binary hash/tree. TXT/DRTM can enable AEM (Anti Evil Maid) with Qubes, SystemGuard with Windows IoT and hopefully future support from othe…
Where are you seeing devices without Bootguard fused? I'd be very curious to get my hands on some of those...
