Raid 0 with two SSD's (Low Write speeds)

[Nikokas5]

I have 2 ssd's http://www.newegg.com/Product/Product.aspx?Item=N82E16820226370

I recently put them into raid 0 and installed windows 10 on them and i get really low write speed compared to read speed which are normal!

If there is an explanation please let me know! Thank you in advance 😀

Well first thing, RAID 0 is almost pointless for SSDs. You wouldn't be able to tell the difference if I put a non RAID0 and RAID0 in front of you.

Second, it might be the SSDs are not working with the controller properly. What RAID controller are you using? Did you create the RAID in Windows or in firmware?

$45 x 2 = $20 more than the equivalent size top tier SSD, 850 EVO 120GB

SSD + RAID 0 - read this all the way through.

I did this because i had one 60gb already and after 2 years of use i felt like a need a bit more of space on the SSD. 120 gb are plenty now.

So i made the SSD on the firmware and i got the AMD sata controller drivers installed! I have to mention tha even before the raid both SSDs were showing low write speeds something like 450mb/s read and 60mb/s write.

I explained the answer above. Thanx for the reply

Then it has nothing to do with RAID or no RAID, but rather those particular drives.

RAID 0 won't make bad drives faster. You just have slow drives, twice.

 

[jimmysmitty]

Ok AMDs SATA controllers are ok, typically for RAID Intel has better controllers.

That aside the only tip I can suggest is to make sure you have the latest AMD chipset and AHCI driver:

http://support.amd.com/en-us/download/chipset?os=Windows+10+-+64

You might also want to install the AMD RAIDXpert since you are running RAID.

Also, are these running in AHCI mode or IDE?

Why would they be bad?

Mushkin has never been a great brand for their procuts. Mostly meh.

Try what I suggested to see if it helps anything.

Look at the ATTO benchmark aswell please 😀

I said 'bad', because you mentioned "low write speeds".

I take it you've never seen Mushkin Redline

 

[jimmysmitty]

I don't need benchmarks to tell me what I saw when working in a repair shop. I had more failures with Mushkin SSDs than Samsung or Intel (the two top SSD brands).

You can have the best performance but if it doesn't last or fails faster it is pointless.

Again, I am trying to help so make sure you have the latest AMD chipset, AHCI and RAID drivers installed.

How full was that original 60GB?

Please enlighten me 😛

Yes I have. I wouldn't use it personally, I have always used Corsair and never had an issue. We had more issues with it than Corsair but less than with most value brands.

That is the problem with making assumptions, you assume something that is completely wrong. I have been working with PCs for a long enough time to know when to call something what it is. Mushkin is meh. It is not amazing but it is not crap. If I bought a new SSD it would be between a Samsung or Intel. If I bought new RAM it would most likely be Corsair. If I bought a new PSU it would be Corsair or Seasonic.

This is not helping the OP but he hasn;t really replied to my suggestion so meh.

It's also absurd to suggest that there's no benefit to RAID0 for SSDs. I'd take a larger capacity any day, sure, and the real-world performance is relatively unchanged, I'll agree; but the fastest speeds possible are only achievable by RAID.

like 10 gbs available... But i was just trying not to put anything on it...

Now i got the whole glitchy batman on it (50gbs) and im not getting any tearing...

Sure, the Dominator Platinum series are phenomenal. The Redlines are no joke though, far from "meh." I'll agree their SSDs are rather lackluster but my question wasn't an assumption it was rhetorical.

Well i never had a problem with the first drive and i really trust muskin out of my experience! So by the time i have the bugdet I will surely go for intel or samsung! For the time being i will stick with this combo.... Thanx for the replies mate 😀

2 x 120GB SSD + RAID 0 = 240GB
2 x 120GB SSD with no RAID 0 = 240GB
Your only real benefit is a single drive letter, vs a C and D drive.

Personally, real world performance is what counts for me, because I live in the real world.
For some certain edge cases? Sure...RAID 0 can be a HUGE benefit. For instance, writing a large video file from 1 RAID 0 array to another RAID 0 array.

Since few people have that requirement or setup...and if it doesn't improve performance for what the vast majority of people may use it for....why bother?

Because it has a benefit for servers or people doing large data scrubbing or compiling. You're absolutely right, 2x256GB RAID0 is generally worse than 512GB RAID0 for probably 90% or more of this forum's userbase.

RAID0 can still improve performance.

Which is what we've been saying all along.

Thanx for all the replies guys! You have all been really helpfull and fast on your replies! 😀
