RAID0 vs. TRIM

post #1 of 23
Thread Starter 
I have 2xCrucial RealSSD C300 at 256GB. I am currently running them on my Marvell 6GB/s slot. I've been reading most people use the ICH slot instead...? Should I change over? I would have assumed that 6GB/s would be faster?

Also, what gives more of a performance boost? RAID0 or TRIM for my 2xSSD drives? I have absolutely no care in the world about losing all of my data if it comes to it. Most of my stuff is on an external drive anyways. Basically I guess I am wondering which offers the best performance increase all around? And should I be switching them over to my ICH slots?

RAID would give you the best performance. TRIM only optimizes the empty spaces on your SSD to maximize write performance. If all you're doing is loading programs (i.e, lots of read operations), you'd want RAID.

Stay where you are. You don't have TRIM seeing that you are in Raid0 but seeing that C300's have a good garbagecollection you won't have to worry about it. Keep them in raid0 and don't look back. Also you don't nee to change them over to the ICH slot, the Marvell 6GB is fine

Aren't the C300 write speeds really low?

No way, they are some of the fastest SSD's on the market, read and write.

EDIT:

While fastest on the market might be pushing it, what I meant to say was this.
With C300 you get faster read speeds while sacrificing some write.
But they are in now way really low. 140MB/s

Hybrid is right, the C300 write speeds are just a wee bit south of 75MB/s. A typical Sandforce drive gets around 200MB/s.

But which slot is BEST? I thought 6GB/s would blow the competition away?

If the C300s had good garbage collection, wouldn't I WANT to NOT keep them in RAID?

Keep using the marvell ports, and RAID!

6GB/s is definitely fast than the 3GB/s by a long shot. As far as garbage collection is concerned. You will get it no matter what you use, raid or not, garbage collection will be working. If you use raid you will lose TRIM, but the C300 already have garbage collection so losing TRIM isn't all that bad. So your marvell at 6GB/s in raid0 would give you the best possible speeds while still having garbage collection.
