I have a Mushkin Enhanced Chronos Deluxe 120GB SSD that I just got. My motherboard (GA-P55A-UD3) has a Marvell 9128 SATA III controller on it. This is limited by its PCI-e 1x connection to a theoretical 500MB/s. With my SSD being the only thing on that controller and the SATA III settings turned on in the BIOS, I am getting around 300MB/s. I know these Marvell controllers aren't great, but shouldn't I be getting better than that? Does anybody have any ideas of why these numbers aren't anywhere close to the 500MB/s I should expect?
Wow. I knew the Marvall controller was bad, but I didn't realize I'd be limited to around 300MB/s. They shouldn't even call that SATA III. Would I be better off using the Intel controller if it's just one drive?
The bios are up to date at F11. I just installed the Marvall drivers which did give me an extra ~20MB/s. Now that I'm over 300MB/s, I know that I'm using SATA III. I still think it's odd that the drive is so far from its 550MB/s max.
I'm just using the single drive, so I guess I'll stick with the Marvall controller. I appreciate your suggestion about the drivers. Do you have any other ideas?
I have the same exact problem as you. I'm currently using a p7p55d-e lx motherboard from asus. I have the Mushkin Enhanced Chronos Deluxe 120gb SSD plugged into my sata 6g/b port and am experiencing the same exact speeds with my Marvell controller as well.
Although what is different from yours, my SSD cannot boot alone, there must be a HDD (for example, my previous HDD which is now storage) connected to boot. In my BIOS my controller is set to AHCI, but my BIOS doesn't detect my SSD as sata, only as IDE. The only SATA connected drive is my storage (previous) HDD.
I'm obviously not savvy with SSD's and this is my first. I have unplugged all other drives and such, and have done a fresh install of windows 7 (AHCI) onto the SSD, yet it still insists on showing it as an IDE.
If anyone could help, this would be greatly appreciated.
I've done as you asked and set storage config as AHCI, disabled all other drives, and made the SSD the boot priority.
Reinstalled windows 7 and it is still showing my SSD as IDE in the boot device priority screen. In the 'AHCI storage' menu, it only shows 1 drive using a sata connector, and that is my old HDD. It does NOT show my new SSD being used as SATA at all.
My BIOS is up to date (flashed it prior to receiving SSD)
I had also browsed around the internet for fixes and had already done the regedit fix and it is still set as '0'
On the bright side, it seems my SSD is more responsive and boots up alot quicker (probably due to AHCI storage setting)!
The only problem I have left is making my BIOS recognize the SSD that is plugged into my SATA 6g/b port, instead of only my old HDD.
I recently got a Mushkin 120gb chronos and my r/w speeds are far below what I was hoping for (edit: 240 mb/s write and 405 mb/s read). I sent an email to Gigabyte support (no reply after 3 days) and I sent an email to Mushkin support and this is what they said....

You are using an X58 mobo, all the Intel SATA ports are SATA2(3Gb/s)
The SATA3(6Gb/s) SATA port uses the Marvell 9128 controller, that is as fast as that controller is capable of going.
The limitation in read and write speeds is caused by the available SATA controllers on your mobo.
I am using a GA-x58a-ud5 rev 1 mobo. Apparently the Marvell controller, which is my only option if i want to stick to sata3, is falling behind the other mobo's. If I had known this I would have got an ASUS mobo or a cheaper Gigabyte board. I hope Gigabyte will return with some good news but as of now I am disappointed. Regardless the ssd is still a huge improvement over my WD black hdd. I can live with it.
