Intel sued over Raptor Lake voltage instability

Intel was sued in a federal court in San Jose, California, on Tuesday, based on claims that the chipmaker's 13th and 14th generation desktop processors from 2022 and 2023 are defective. The plaintiff, Mark Vanvalkenburgh of Orchard Park, New York, purchased an Intel Core i7-13700K from Best Buy in January 2023, according to …

First world problems

I read all these tales of woe that befell the cRaptor Lake intel chips and decided I would buy AMD on the next round.

Now I'm wanting to build a NAS. Eventually found a (footprint x small) case chassis that will work, for sale in this backwater (has 4x SATA bays). So now I go hunting for a Mini ITX AMD mobo. I'm about to trigger a transaction on this CPU/board combination that I like when I notice: the AMD chipset only supports RAID 0, 1, and 10. Check specs for the intel motherboard: supports RAID 5. Check another intel motherboard: also supports RAID 5. So currently on order: Intel Core 5 14'th Gen and a matching ITX mobo.

Conclusion: Over here in the sticks in the backside of africa one has to make do with what one can find.

Re: First world problems

Why are you using the RAID from your BIOS? You should be using filesystem level RAID as supported by any modern filesystem or something like mdadm.

Re: First world problems

Yes. If you are using RAID in your motherboard, what happens if the motherboard dies? If it's implemented right, you should be able to move the disks to a different motherboard of the exact same model. If it's not implemented right, you may not even be able to do that. Moving the disks to a different model of motherboard... no idea if that will work. No idea if motherboard manufacturers document their disk formats to make life easier should you need data recovery.

(If you have 4 disk RAID 5, then data is striped across 3 disks and the fourth is parity. Fine. But what order are the 3 data disks in, and which disk is parity? Sane RAID 5 implementations will write this information to one of the blocks on the disk. But there's not one standard format for that, so no guarantee of compatibility if you change controller/motherboard. And insane RAID implementations may not write that to the disks at all, just store it in the BIOS's persistent settings).

If you're using RAID at the OS block layer or filesystem layer, then those questions have well documented answers - of course you can move to a completely different motherboard.

4 disk RAID 5

Technically, what you describe is RAID3, not RAID5. RAID5 stripes both data *and* parity blocks across all disks, to better balance the load on the disks. RAID6 adds a second parity block to each stripe.

Re: First world problems

More like if it's not implemented right, you won't be able to even unplug a drive with the system OFF without losing the set.

Re: First world problems

We could not figure out why we were having really dumb issues with our new Dell Windows 11 notebooks, until we changed the BIOS settings to AHCI and re-imaged them.

No more problems after that.

We still cannot find a definitive answer as to why Dell configures their notebooks with RAID mode enabled, we kept finding the notebooks would bog down when very little was running on them and CPU would hit the roof, we originally just blamed Windows 11, but as soon as we applied the fix and re-imaged the machines, the instances of Windows basically locking up intermittently stopped. CPU still hits 100% intermittently but that's M$ Endpoint protection scanning stuff, even though it shows as being turned off because CrowdStrike FalconProtect is the AV solution, so another lie from M$.

Re: First world problems

I built a six disk nas system based on Truenas Scale, after a few issues making a bootable usb image of the installation was easy, and I have not looked back, easy to manage, good performance, definitely recommend it.

Re: First world problems

You also should be seriously reconsidering your desire to use RAID 5. RAID 5 is starting to be considered out of date because the size of modern drives taxes them so hard during a rebuild that additional failures, leading to a complete loss of the array, is a major concern.

There's a reason why RAID 10 has become so ubiquitous an inclusion nowadays.

Re: First world problems

Another reason why filesystem-based redundancy such as that from btrfs, combined with LVM, is catching on.

Re: redunancy

I am just about to implement a 4-drive 48TB RAID10 and am thinking about also going ZFS, but I'm wondering if that is a bit of overkill.

Re: First world problems

I'd use some well known raid OS like readynas, and do it all in software

If you want redundacy DO NOT USE RAID 5

There was an excellent web site called BARFFF.org I think. That discussed the merits of all the RAID offerings. Summarised RAID Five, RAID Four and RAID Fhree were bad choices.

RAID 10 is the only RAID to use.

I saw a site 25 years using RAID 5 using 4 drives and a parity drive. Every day for a week every drive fail in turn and on the 5 day the last one went and they lost all their data.

Re: If you want redundacy DO NOT USE RAID 5

Just found this helpful site

http://magj.github.io/raid-failure/

Calculates RAID 5 and RAID 6 rebuild probability. Consumer drives have a 10^14 error rate, enterprise a 10^15 error rate.

The probabilities of successfully rebuilding a 4-drive RAID 5 with 12TB consumer drives is ugly, 6%.

Why go software raid, you can pickup an ex-corporate hardware raid card with battery backup off eBay, I got a Dell SAS card for £11 for one of my servers when I found out the current raid card didn't support standard disk mode for Unraid and couldn't be bothered to go through all that firmware flashing.

Commenter said they're in Africa, eBay shipping is nightmarish enough as is. Although, there are drop-shippers in the US/EU these days to avoid that stuff.
