Als je 4 M.2 sloten belangrijk vindt en je gaat ze vol steken met SSD's, dan kies je een moederbord dat 3 SSD's rechtstreeks aan de CPU kan verbinden. MSI heeft dat in hun assortiment.
Dat is shared bandwidth met de PCIe slot voor de grafische kaart:
M.2_1 Source (From CPU) supports up to PCIe 5.0 x4 , supports 2280/2260 devices
M.2_2 Source (From CPU) supports up to PCIe 4.0 x4 , supports 2280/2260 devices
M.2_3 Source (From CPU) supports up to PCIe 4.0 x4 , supports 2280/2260 devices
M.2_4 Source (From Chipset) supports up to PCIe 4.0 x4 , supports 22110/2280/2260 devices
6x SATA 6G
* PCI_E1, M2_2 & M2_3 share the bandwidth. PCI_E1 will run at x8 speed when installing devices in M2_2 or M2_3 slots. Please see manual for more details.

Dit is een voorbeeld van wat je niet wilt.
4x M.2
M.2_1 Source (From CPU) supports up to PCIe 5.0 x4 , supports 22110/2280 devices
M.2_2 Source (From Chipset) supports up to PCIe 4.0 x4 , supports 2280/2260 devices
M.2_3 Source (From Chipset) supports up to PCIe 4.0 x4 , supports 2280/2260 devices
M.2_4 Source (From Chipset) supports up to PCIe 4.0 x4 , supports 2280/2260 devices
6x SATA 6G

Daar staan 3 SSD's samen met de SATA-poorten, USB-poorten,... te vechten om bandbreedte dat in totaal slechts PCIe 4.0 x4 is.
Een zwaktepunt van de eerste generatie AM5 chipsets, is dat het met 4 lanes PCIe 4.0 aangesloten is. Bij Intel kan je voor een duurdere chipset kiezen dat met 8 lanes PCIe 4.0 aan de CPU verbonden is, maar bij eerste generatie AM5 zijn de chipsets bandbreedte gelimiteerd. Tweede generatie AM5 chipsets kan een verdubbeling van de bandbreedte tussen CPU en chipset (4 lanes PCIe 5.0 ???) mogelijk maken.
Het voordeel van een B650 tov X670 (of B550 tov X570 bij AM4) is dat er niet genoeg lanes uit de chipset voor de M.2 sloten komt en ze moeten wel 3 M.2 sloten aan de CPU verbinden.
Intel 2,5 Gbps netwerkchip is eerder een nadeel dan een voordeel. Ontwerpfouten zijn al in 2020 toegeven.
Intel i225 "Foxville" 2.5GbE PHY Has a Flaw Affecting Performance, "Rocket Lake-S" 2H-2020 Production Confirmed
Intel's i225 "Foxville" family of 2.5 Gbps wired Ethernet controllers have a design flaw that affects performance, according to an official advisory sent by Intel out to its motherboard- and OEM PC partners (notebook- and pre-built desktop manufacturers). There are no security implications of this advisory. The i225 family of 2.5 GbE chips are being extensively implemented in upcoming motherboard, desktop and notebook designs. The i225 "Foxville" family consists of the i225-V targeted at motherboards and notebooks with Intel chipsets that have integrated MAC; while the slightly pricier i225-LM has an embedded MAC, and targeted at other platforms (extensively found in high-end and upcoming AMD motherboards).

De opvolger zou het moeten oplossen?
Intel Patches Stuttering Ethernet Issues, but It's Just a Workaround for Now
MSI has made the update available for its I226/I225 and Killer E3100 2.5GbE motherboard users.
Intel is still working on a comprehensive fix for the intermittent Ethernet connection issues we highlighted in a report back in January. In the meantime, it has a workaround that basically turns off Energy Efficient Ethernet (EEE) mode. MSI appears to be the first Intel partner to release an installer delivering the workaround. Intel says it is continuing to “work towards a solution.”
https://www.tomshardware....just-a-workaround-for-now
Intel Raptor Lake motherboards often leverage the new Intel I226-V controller, so this intermittent connection issue (which similarly annoyed users of the previous-gen motherboards/controllers like 2019’s I225) continues to provide disappointment to the newest-gen customers.
Previous advice regarding workarounds, such as reducing the controller’s max transfer rate to 1 Gigabit, were not bulletproof when we last reported on this Ethernet issue. However, Intel appears to have narrowed down the cause of the connectivity dropouts to some kind of energy-saving functionality present in the driver. Unfortunately, it wouldn’t be the first time that energy efficiency implementations end up causing users to spend a lot of their personal energy in fault-finding and fixing productivity sapping side effects.
Ik zou niet bijbetalen voor iets dat graag aan disconnects, stotteren,... doet en met workarounds, ducttape,... bij elkaar gehouden wordt. Ze hebben al minstens 3 jaren tijd gekregen om een goed werkende netwerkchip te maken.
Om een Intel goed te laten werken moet je de netwerkchip op 100 Mbps begrenzen.
The hardware reset bug is specific to the i225 (and seems now the 226 series), the i211, 217 and 218-V or -LM are completely fine.
The higher the data rate the higher are the chances the thing will completely crash. It's seemingly a controller design fault, as even after driver, firmware and hardware revisions the issue still seems to occur every now and then.
My general advice is if you have v1 or v2 hardware and need link stability limit it to Fast Ethernet (100 Mbps) mode and go no higher, gigabit is usually fine but will occasionally lock up on i225-V B2 from my experience. 2.5GbE will cause the earlier revision chips to crash quite often.

This thread has destroyed my regrets of not getting an X570 board w/ the I225-V instead of Realtek.
I've had 'similarly symptom'd' problems in years-gone-by on Realtek NICs. I guess 'holding out for (affordable) 10GbE' wasn't the worst choice, I'm just gonna be waiting even longer.

Als een Realtek rare dingen doet, dan is het wel te verwachten, maar je hebt geen premium betaald voor een chip die graag aan disconnects, stotteren,... doet.
