RAID works by having multiple legends and heroes living in the shadows.

Never since a security bios patch update ate my entire array.

"Hard won experience" - This... I felt this when you said it. So many nights working through the AORUS RAID tools both SATA and Nvme. So many more nights making server 2019 Core work with an AORUS board to begin with.

I am taking classes for my IT A+ certification tests, and we just started talking about RAID this week!!! Thanks for the info!!!

[josephletts]

This man goes through so much pain so you don't have to. Only total respect.

[hightech-lowlife]

The only raid I would EVER do is raiding the pantry for orange soda and snacks.

[galdutro]

Can you do a comparison between file systems that support raid (ZFS/Btrfs) and also solutions like intel rapid storage?

[ProcessedDigitally]

15:35 Makes sense. I once had a MOBO SSD RAID0 (using two earlier Sandisks) on a MSI 990FX board for boot and OS (WIN10). It was good performance when the Raid was new but over time the writes slowed to just 150MB/s coming from over 600MB/s. The reads were not affected much. I even thought the disks were getting 'worn out' but I removed them from the Raid and formatted then and turns out the disks were pretty much good the same. Maybe TRIM issues were the prob.

I'm a big fan of the linux raid10 with the F2 layout, even with just 2 drives. Read performance is identical to raid 0, write identical to raid 1. Not sure if it still matters with fast SSDs (compared to the near-2 layout), but I don't really see any downsides.

"Intermittent" the worst thing to hear when talking tech.

Growing up I got into so many re-install scenarios with my PC builds due to my own ignorance about RAID. One particular build in the early-2000s I was doing a RAID 0 setup with two WD Raptor 74GB drives using a PCI (not PCIe) RAID card. I reinstalled Windows and games so many times troubleshooting corrupted drives that to this days I remember the majority of CD keys for my big games from that era.

Since those days I've generally stayed away from using RAID, although recently I started messing with ZFS and Windows Storage Pool stuff. Thanks for yet another fun video, L1T!

[pdamasco]

Thank you for bringing this up. I spent a lot of time struggling with RAID on my x370 gigabyte board and ultimately I just had to ditch the idea and bought a larger SSD with a huge gaming/backup HDD.

[nosirrahx]

My workstation runs 4 905P drives mounted on a Hyper 16X in VROC RAID 0. The performance was pretty untouchable when considering both sequential and 4KQ1T1 until the P5800X came out. After some tuning and OCing I get 200-220MB/S 4KQ1T1 read which is nuts for a drive that also has insane sequential read.

[brenlyd]

Thank you for this video! Your wording is straight and to the point without being too meandering. Even when you have little asides you're keeping each one to the point. You rock!

Wendell: "Theres something wrong with the reads"
Me: LITERACY!!

[nukedathlonman]

Well, I agree, RAID on motherboards hasn't been overly hot. But doesn't using RAID on SSD's pose problems with Trim and also increase (exponentially) write amplification?

[chrcoluk]

Problem with windows software raid if you have a unclean shutdown, it assumes it needs to resync data and so you get a slow rebuild forced on you, and I found out from Macrium documentation a while back that dynamic disks in windows are depreciated. So I stopped using it.

However software raid in Linux and BSD is awesome, and I stay away from hardware raid and onboard raid systems.

[NorySS]

Intels Marketing also blocked NON-Intel NVME drives from working on Z590 platform.

[MrMalchore]

Ya, a ramble of a video indeed. I know the topic was about motherboard RAID (specficially AMD firmware) but all focus was lost after your returned from your sponser message.

...so anyways, I have three 1TB WD spinning hard drives I'll raid together in RAID 0 as my backup and Steam game library volume. It won't be my OS volume - that'll go on a single nvme drive (with no raid to speak of.)

[JonathanSwiftUK]

When discussing Windows Raid it would be helpful to clarify the two types, that through disk manager, and those via Storage Spaces. Worth mentioning that some features are depreciated - for example spanned disks. Storage Spaces is the preferred method for Windows software Raid. For me you can't beat hardware raid with a decent memory cache and battery backed write caching. RST motherboard using Raid 0 is a fast option, but no data resilience - good for test/lab systems only.
