Storage Questions

[hug0mac]

I am wondering

 

• Can you pair one M.2 SSD with one mechanical HDD for RAID?
• How much can you write data to one SSD before it fails?
• When do you need a RAID card?
• Can you tape a HDD to the side of the case as long you don't cover the holes?

 

 

thanks   last one is a bit ghetto i know

I don't know about taping a HDD to the side of a case, they do have moving parts and vibrations might be an issue.

Probably...but i like to be creative... but it wouldn't vibrate that much ...i know worse stuff.  :huh:

It could damage the moving parts in the long run. Most HDDs sit on rubber shock-absorbing pads in metal cages all their lives

it will damage the HDD

Okay, I want to preface this by saying that I don't know very much about RAID, but I think the way RAID cards work is it adds more SATA ports as well as offering different RAID formats then the standard RAID controllers built into your motherboard. Also, I know some RAID cards come with a battery to prevent data loss in the event of a power loss. 

 

Taping a drive? I mean, sure, you could do it, but the vibrations would transfer into the metal of your case and be amplified. Also I would worry that those same vibrations would loosen the tape over time.

 

SSD writes? A lot.

 

m.2+mechanical? Probably, but not with RAID 0 as that requires drives to be the same capacity, however the performance of that m.2 drive will be drastically hindered by the mechanical drive, so you probably shouldn't.

1. You can use it as cache sometimes

2. Far too much to worry about

3. When you don't have raid on your mobo/need more drives in raid

4. Best not to, as it might fall and lose data.

Thanks for the answers! Really helped me!

My case don't have rubber pads...i should worry! :wacko:  oh wait i don't got any hdd yet   it maybe broke

[hug0mac]

the reason I ask those questions is because

 

1. i like the idea of raid but didnt know if ssd+hdd works so thanks for the answer all!
2. i had a ssd that stopped working and i was thinking it was because i did write too big files to it all time...so at least 100TB write?
3. because in future i kinda will put 3-4 hdd in my pc and raid fits good and i was thinking that was too many...
4. just friday creativity

1) that would be horrible because you're basically bottlenecking your SSD speeds with a HDD

 

2) several petabytes if its a good quality SSD, current SSDs are far better than the ones from a few years ago

 

3) you should always use a raid card because software raid is a lot more likely to cause issues and corrupt your data

 

4)yes but velcro is better because the adhesive is very strong and it will also dampen vibrations from passing yo your case, making it quieter

1: should have thought of that! sad that it isnt the other way (500MB/s HDD   )

2: you will laugh but it was a kingston ssdnow 120gb...  :lol: is petrabyte 1000TB?

3: even with intel rapid storage? i heard hardware is always better then software but.

4: makes sense! thanks for the tip. but hard drive cadges is loud too or?

yeah, 1PB is 1000tb

 

i have seen a lot of people that come to the forum because their raid array just stops working, and the only option is to do a clean install and lose all the data

if you really need more speed just buy a single NVME ssd, which is much faster than two regular SSDs, and is more reliable

 

yesh hard drive cages also transfer vibrations unless they are dampened

noted!

Addendum: Until a few years ago, most HDDs were mounted without rubber dampeners and it wasn't an issue.

Having said that, taping it to the case is not exactly the same as tightly bolting it into a mounting cage, so your

milage may vary.

 

 

3) you should always use a raid card because software raid is a lot more likely to cause issues and corrupt your data

 

Even the firmware on a RAID card can have critical bugs though, both hardware and software RAID have their

upsides and drawbacks. ZFS and mdadm seem to work pretty well for many large and small deployments (although

there was that nasty bug with discard and RAID0 in the Linux kernel a few months back).

If we're talking about integrated motherboard RAID and dedicated RAID cards, yeah, lots of people come by

here with breakage on that front. I don't think I'd ever use integrated pseudo-RAID functionality on a

motherboard personally unless we're talking about a server board which happens to have a proper chip for

that purpose.

yeah, like the raid card that linus was using and completely messed up his LMG servers lol

 

but yes i meant compared to a consumer motherboard, a dedicated card is much safer

i kinda feel that way too about software/hardware, it matters what controller and i dont think that a z97-e mobo have a good one...but raid cards is so expensive or?

[alpenwasser]

Ouch, hadn't actually heard about that one as I've barely been around and

haven't kept up with the videos.

But yeah, figured you were talking about that, just wasn't quite sure.

It depends a bit, but yeah, decent ones usually aren't cheap. As Enderman said, an NVMe

SSD is a saner solution in most scenarios these days,

Yeah, second-latest vessel video

"one of the raid cards crapped all over the inside of its pants, took its pants off, and started swinging em around" -Linus
