Raid controler

[Appelzaadje]

Hey all i currently run 2x Corsair Forse 3 GT 60Gb in raid 0. However i noticed no increase or only a litle in speed by doing so with the onboard controler. Can this be because of the onboard controler being to slow? and if so what would be a good controler for 2 drives.

I was thinking about something simple like Silverstone EC05.

Anny hints or tips on if this would help or increase speed.

 

Also my PC posts verry slow when its in raid config so this is also a reason for me to change to another controler.

It's not the controller. It's that RAID 0 SSDs doesn't really increase speed very much, if at all.

 

What is your drive doing?

then why does raid 0 improve the sequencial speed off my hdd's so much? there just OS drive's atm and all programs besides games are on it

This is because the drive has to get small chunks of information from random different parts of each drive rather than one long concurrent stripe of information that it would during a sequential read/write.

 

EDIT: think of raid 0 like a DJ, he ques up the next song while the first is playing because he knows what to get next (this is a sequential read/write function) but if he does not have a playlist (random read/write or non-sequential) then he doesn't know what song to que up until after it is needed, there it wouldn't matter if that song was on a separate disc or not.

Something like that.

 

Unless you are doing enterprise grade workloads, RAID 0 only really provides benefit in sequentials. It can provide a little benefit for applications like the Adobe suite (as a scratch disk) or a Virtual Machine drive (where lots of VMs are competing for storage resources).
