Did you tell that to Apple and Nvidia? So you expect to connect a SATA III SSD to a USB 2.0 port and have it run at SATA III speeds?

 

When you find a SSD that operates as you have decided it must, let us know…

 

Are u stupid or what? If i use a sate3 disk in a sata2 controller i expect that it goes as a sata2 disk, not 1.5 or less with random freeze…

And tell us: why ocz, samsung and owc work perfectly with nvidia chip in mac? Why no one from sandisk says a word in this thread about this problem?

If you’re happy to give money for defected product in return…

+1!

This is not an NVidia only problem but an imcompatibility between sandforce and NVidia chip. Sandforce had already fixed the problem so, what is sandisk waiting?!

Hello, SadDisk? Does your new firmware update fix this problem?

I don’t know what happen but i’m still have 1,5g sata connection speed and i have macbook pro with mcp79 nvidia chipset - what the hell is going on??

p.s. For those who have macs - remember to flash to “211 m” firmware. 

Thank you sandisk…

I have already updated mine too…its working nice…a little bit faster…

Have you guys feedback…

I have no problems during the update…after the system has totaly fine… :smiley:

Folk, go look here for SanDisk answer:

(I guess I’m being picky to think SanDisk support could have alerted folk on this longtime thread re a fix for the problem.)

finally update for negotiated link speed problem !!!

sandisk extreme 240GB black magic test results: 

READ: 263.4MB/s
WRITE: 193.4MB/s

snow leopard A1286 macbook pro 2009 aluminum unibody with nvidia sata controller. 

Yes !

Thanks Sandisk !

How do I proceed when no optical drive is available?!

you can put the ISO on a USB drive using a program like power ISO. 

I did exactly that on my PC but the MPB doesn’t recognize it as possible startup disk even though it shows up in finder as Firmware Updater. I tried pressing C or E at boot time but nothing. Help please!

looks like you will need to put the SSD in a computer where there is a CDROM availabel or use an external CDROM. 

I even tried with a SD card to no avail. I can’t believe I’ll have to go buy an external drive for this…

Any new firmware updates yet?

Im still getting 1.5 negotiated link speeds on my White MB Late 2009 Unibody.

there is an update for this stickied at the top of this board.

OCZ and Samsung SATA III SSDs work fine at SATA II speeds on the Nvidia chipset? In your dreams!

OWC may have applied the firmware work around to fool the Nvidia driver into staying a SATA II speeds, since they aim at the Mac market, but I don’t follow their products.

Yes I agree, I would expect a SATA III SSD to work fine with a SATA II controller, and all SATA II controllers do work that way… except for those made by Nvidia, and their terrible drivers. SATA controllers are called that for a reason, they _ control the drives _ they work with, not the other way around.

Oops, I forgot, don’t bother you with technical details and reality.
