Marvell Controller 9128 Myths?

post #1 of 8
Thread Starter 
I just wanted to put in my two cents about running your new SSD on the Marvell controllers.
I just got a Vertex3, 120GB, SATA3 SSD and didn't believe that it wouldn't operate fine on the Marvell 9128, SATA3 (6GB) controller. After all, I've seen post of this drive hitting 550 mb/s on the P67 chipset. I know that there is a bottleneck problem with the X58 chipset, but I still saw benchmarks up to 400mb/s with it. I'm also running a RAID0 array for data, so it only made since to seperate the two (SSD in AHCI, SATA in RAID)
After the install, I ran ATTO benchmark as suggested. You can see the Marvell controller results here. Wow! This is great, over 420 read and not bad write scores. Well, this only shows how insignificent benchmarks can be.
I then installed my RAID0 array and starting using the setup to reinstall programs, etc. It seemed like whenever I clicked onto something there was a slight delay. Then after I was backing up my accounting program (Quickbooks) the system just "hung" when I went to close the program. It finally closed after about 30 SECONDS. Whenever I jumped from one program to another, there was always this strange pause.
I then did a secure erase of the SSD, set the partitions, aligned it and reinstalled Windows7 x64 on the SATA2 ports, using Intel Rapid Storage drivers in ACHI mode. I installed the RAID0 array on the SATA3, Marvell controller. That's right, I have a SATA3 SSD on the SATA2 ports and two SATA2 RE4's on the SATA3 ports. Figures, don't it!
After running ATTO again, I was a little depressed (like everyone else) that they wern't very impressive. These are the Intel controller results. But what a differance for "real world" use. My system now is much, much more "snappy". Nothing hangs, everything loads in instantly. Even Windows loads in no time with Norton. The RAID0 array took a slight hit (Marvell controller is garbadge), but it's only for data and some games and not really noticable. Now I have "Trim" support for the SSD, for sure. (Thanks for making that perfectly clear Marvell......NOT!)
So, If you think it's all about higher speeds in benchmarking and are just sticking with running your new fancy SATA3 SSD on the Marvell 9128 controller, then your making a HUGE mistake.

Here's something else that is weird with the Marvell controller.
This is a benchmark of my two WD RE4's in RAID0 on the Intel RST controller (SATA2);
HD Tune Pro Benchmark with Intel RST
And here is the same setup on the Marvell 9128 controler (SATA3):
HD Tune Pro Benchmark with Marvell 9128 controller
Besides the huge drop in transfer rate. What's with the "rollercoaster" effect the Marvell controller seems to produce? Access time is just about the same at least.

Why not put the RAID on the Intel controller also?

Then I'll have to set SATA as RAID and I won't have "trim" support for the SSD.

Yes you will, providing the SSD is not actually in a RAID array itself.

I know RAID IS ACHI, but I thought once i set it to RAID then taht was it for trim. It does make since that if the SSD is not in the array, that I'll still have trim. ugh! Another reformat. Are you 100% sure on this?

He is correct, Intel documented this support ... somewhere. TRIM is supported on intel controllers set to RAID for single drives not actually part of a RAID.

I changed everything back to the Intel RST controller. The best thing about the Marvell controller is you can "disable" it in bios. Then you won't have to see their ugly post screen every time you start up your computer. I wish I could rip their chip right off of my MB and ship it back to them.
My Vertex3 is operating the best I've seen on this board. My RE4 RAID0 array is back to normal, so I guess I'm as happy as I'll get with this set up.....for now!
Thanks for your help guys.
rep+ for everyone.
