Raid 0

[deathstar13]

Hey guys i need some help and info on raid 0
From the start of my OC career ive always run raid, But this is way beyond what i use to know and do.
I have an Asus B650 AM5 with 3 M.2 slots, With one being Gen5 and the bottom two are Gen4

Im putting a Gen5 Crucial T705 2TB in my gen 5 slot for windows and programs.
yes i know all the specs and wasted money ill have by doing that.
But my main idea is Running the mobo raid0 on 2x 2TB Gen4 M.2 or getting a 4 slot hardware PCI raid card.
Im just not sure which yet as im just thinking and researching still.

Any drive i use will max out my sequential reads and writes until it hits a wall at about 7000MB
But what im looking for is boosting random reads and writes which can have tons of room to speed up. id love to see 400-500MB there.
So in theory i think the Gen4 drives and buss's wont be no faster on large files, But should multiply the randoms depending how many drives i use.
My plan is 4TB total for these Gen4 drives and used for gaming, But the randoms should make it very snappy. Even faster than a good Gen5
Ill be buying my drives real soon and not sure what to buy. The goal is 4TB total minus a card if needed.
1x 4TB Gen4
or 2x 2TB Gen4 on my Mobo raid.
or 4x 1TB and a raid card for a 4 stick stipe.

It was already covered multiple times in your other thread. RAID 0 is worse in everything but sequential bandwidth than a single drive. At least it looks this way on desktop motherboards.

Sorry to make a thread to ask, i have bad short term memory.
To me the small randoms would have to increase as there is nothing stopping them and holding them back.
So in my mind it would be 4x of the speed of a single stick.
Ive watched alot of videos but none were specific enough so ill go with what you say as i dont want to waste money on a theory.

@Nebulous runs Raid 0 on spinners and a pair of NVME drives. He might be able to provide some insight if you really want to go that route.

There is virtually no reason to run raid0 on ssds let alone nvme drives outside of a cool benchmark picture. You won't notice any real world difference whatsoever, outside of your wallet being lighter.

 

[deathstar13]

Im just thinking of ways to boost my random reads and writes which would make things more snappy. Even a 200mb increase would be noticeable.
But yes, im not gonna make a $500 bet on a hunch.

Again im sorry to re ask this question, But i live to tweak and fix things pc wise and am OCD about it.
Id tweak my start button if i knew id gain something from it.

Thanks for the shoutout! Well you might notice a little zip with spinner drivers, but with NVME drives, it's a big fat zero. I only raided spinners for the capacity. I'm a cheap sob, so I grab large spinners and raid them because I can't afford large SSD's.

Really don't know what else to tell ya. Try raid and see for yourself how your system does with it. Raiding SSD's or NVME's is a waste.

 

[deathstar13]

i hear ya man, Id love to pick up some cheap WD Raptors for old times sake.
I guess ill just have to find a way to tweak my power button then.
Thanks for the help!

 

[deathstar13]

im taking everyone's advice here on this topic, NO NVMe raid 0
BUT i did find a project that ill call "Deep storage" which is my mobo supports sata3 raid with 4 inputs.
Then i found 1GB WD Velociraptors for $30 each so ill raid stripe those 4 drives and end up with $120 for 4TB of storage. This will be for OS iso's and things i dont use much.

Sweet! Would love to see that benchmarked!

It will most likely be as fast as a Sata3 SSD single drive.
Back when i stopped oc'ing i was using 2 Raptors in raid 0 and it was really a big difference over 1 7200rpm drive.
I think back then i had like 500GB in storage. I should be at 10TB after building this setup.
I swear games were 10GB at most and now i have games that take up 100GB
Ill be testing the heck out of all my drives since i have so many planned to go in. 2TB Gen5 and 4TB of Gen4 and 4TB of raptors. it should be interesting to say the least.

 

[Woomack]

I don't want to disappoint you, but a single SSD is faster than any HDD in RAID. Also, new HDDs are faster than Raptors, even those 5400 RPM.

 

[deathstar13]

Have you seen the prices of 1TB SSD's lately? $50 a TB on an SSD
This will cost me half as much. $125 out the door for 4TB of Raptors.
Im not doing this out of need but rather for nostalgia and fun. Thats why im not looking at modern hard drives also.
Im retired and have no life so i do stuff like this to occupy my time and have fun.
Ive looked into doing the SSD's like you said but at $200 id rather invest in NVMe drives.

Fair enough, you were also concerned with random reads and such and moping about not getting the highest end cpu

 

[deathstar13]

Every purchase i look at the ability to tweak what ever it is, and things i can make it better.
I just whined about the cpu as i haven't even fired mine up yet and would have liked to see these new cpu specs and price and have the ability to choose them if possible when i bought mine. But what i have i doubt ill ever really max it out.

Random reads and writes in NVMe drives in Raid0 makes me wonder what's holding the speed back. And also why they dont follow any other type of drive in Raid0, whats making them hit a wall? Sequential reads and rights can be maxed out. I will say who ever can remove most of that wall on the randoms will make a killing as alot of people wont buy Gen5 now since no matter how fast the sequential's are they are still stuck with slow Randoms both Gens share.

 

[freeagent]

If anything, you will notice higher CPU usage when using your drives, that makes it suck.

People have known that since these released well over a year ago (its like this for 4.0 drives too). IMO, it's mostly price vs. 4.0 that holds people back these days. There improvements from last gen in both seq and random.

Oh i believe that especially with software raid, Im not sure if they count Raid on my mobo as hardware or software. Ill only do hardware Raid so i gotta dig into my mobo specs as much as possible
Windows will be on my Gen5 cpu slot and 4TB od Gen4 for games.and then the 4TB of Raptors just holding big files like ISO's

If i had to guess my SATA ports on the mobo are hardware raid.

 

[EarthDog]

It's software raid on your mobo, bud. Hardware raid would be a card with it's own controller.

How many ISOs do you have that you want to stash them on 4TB of ancient spinners in Raid?? I know you like to tinker (no tinkering past initial setup mind you) but, just seems like you're reinventing the wheel again. Buy a 2/4TB spinner and call it a day.... or slice off 1GB of your games drive (3GB holds a lot of games...)

i see Gen5 as a 75% waste of money over Gen4, But there are gains to be had. But your gonna pay threw the nose to get one. Mobo makers need to start making boards that all NVMe sots are Gen5 and that will drive the price down.
Im putting that 2TB Gen 5 on my Windows drive and i do expect it to make it snappier, But mainly to just have something to play with. Ive seen a few video's on NVMe Raid setups that were all hardware and with 4 drives.
Sequentials went threw the roof speed wise, But only small gains were seen on randoms. Not even close to being worth the price or hassle.
