SSD SATA3 Question

[Superman23]

Hey Guys,

I got a question.

I currently have an ASUS RAMPAGE lll Formula.

Connected to this are 2x60GB SSD SATA 3 GB/s to SATA 6 GB/S slots

Aswell as a 1TB SATA 6 GB/S conected to a 3 GB/s slot

I only have 2xSATA 6 GB/S on my MB,

Where will i get better performance?

having current config or having SSD's on SATA2 ports and Storage Drive on SATA3 port?

Please shout if i have been unclear, thanks for help.

put the drive you are going to install your OS and most used apps on the SSD via sataIII. the larger storage drives can go on sataII

Thats what im currently doing...but the SSD drives are SATA2 and my 1TB is SATA3 am i not wasting the 1TB capabilities...

I would plug 1TB to Sata 3 and SSD's to Sata 2 as probably Marvell is controlling Sata3 on your board and that means there is no TRIM support for your SSD drives

Trim will work on multiple ssds that are not in RAID, if the ssd firmware supports trim that is. And yeah your 1TB drive should go on the sata 2, while your SSDs should go on sata 3.

even though your SDD is SATA2, it won't be bottlenecking.

IE:

• the SSD are faster at read/writes than the HDD
  
• the HDD can pass data to/from itself faster, but is held back by the read/write speeds
  

the only way i would put the HDD on the sata3 was if it's RPM was 10K+

and AFAIK even sata3 WD VelociRaptor's read/write speeds aren't that great compared with SSD

Great thanks guys,

Yea the SSD's cant do TRIM in RAID 0... but i get nice speeds from parity.

Just happy to know im not bottlenecking with my config.

I thought that TRIM is working only on MS or Intel controller/drivers, not on Marvell.

Interesting, after doin a little research, it looks like you are right about the Marvell controllers, I knew they were dodgy but I didn't know they didn't support trim functions. I came across a few posts where people claimed to get trim functionality by using generic MS drivers. But the information I find seems to be scattered and contradictory. Some older posts, some newer. Maybe the problem is resolved by now? Probably not... If that is the case, I wouldn't hook up ssds to the marvell ports. Good call Black.

The thing about the OCZ drives using Garbage Collection when idle even in RAID is very interesting.!

It doesn't help either when people say "controllers" cos there are controllers on the drives and on the mobo.

For example, the updated Samsung controllers on 'older' Corsair drives support trim.

I looked into this a while back.
