velviaster Apr 18, 2012 6:26 PM (in response to YuriY)I am having the same problem. My local computer shop offered my money back... I would prefer not having to do that.
Please fix this.

tobiasvdp Apr 19, 2012 1:54 PM (in response to velviaster)This problem seems to be more widespread: Intel 330 in a Mac Pro with Intel ESB2 Chipset only negotiates on 1,5 Gigabit as well. I am quite disappointed, will probably return the drive

3. Re: Intel SSD 520 and any Apple Macs with Nvidia MCP79 chipset BUG.
bosstow Apr 20, 2012 1:36 AM (in response to YuriY)I too am experience this issue with an Early 2009 MBP 17" and the MCP79 chipset using the Intel SSD 520 480GB. It should be able to negotiate to 3.0Gbps with that SATA II interface, but as the OP has noted, this has plagued other drives with the Sandforce chipset along with this MCP79 interface.
It would be nice if Intel could release a "fix" like one of the other OEMs has done. Their solution was a simple Linux utility that forced the drive to a particular speed.
Come on Intel, please issue us a fix/workaround for this issue!

janneman59 Apr 28, 2012 10:48 AM (in response to YuriY)Im having the exact same problem! Currently running an Intel 330 inside of an Macbook Pro 5.1 (Late 2008) with Nvidia MCP79, and the negotiated link speed is 1,5 GBit while it should be at 3 GBit. My system is also plagued with beach balls every 3 minutes, and then the system is frozen for exactly 30 seconds.
Please Intel, fix this! At least tell us if there is a fix in the works, and an ETA when it will be available. Thanks!
(P.S. Has anyone tried running the OCZ tools to force the 3 GBit link speed in an Intel drive with sf-2281? Just curious.)

5. Re: Intel SSD 520 and any Apple Macs with Nvidia MCP79 chipset BUG.
tobiasvdp Apr 29, 2012 3:51 AM (in response to janneman59)Update: it seems that my problem with the intel 330 and a 2008 mac pro follows a certain pattern:
- when cold booting the machine, i get the 3gbit connection
- when rebooting, i only get 1,5gbit
i then ordered a sata 3 controller for my machine, based on a asmedia 1061 chipset, and thought that the issue would be resolved when using native 6gbit. when connected to this controller, the intel 330 ssd always connects at 1,5 gbit, no matter if i cold boot, or if i reboot.
would it be possible to get some intel tool that would be able to lock the sata speed of the ssd to a certain setting?

Kärki Apr 30, 2012 8:49 AM (in response to YuriY)I have the exact same problem with my Intel SSD 330 and MacBook 6,1 (2009 unibody).
Seeing that other manufacturers are actively trying to resolve this issue, I hope Intel will soon follow suit.

vincchan May 2, 2012 12:34 PM (in response to YuriY)I've got the same problem and it's driving me nuts. My MacBook 5.1 late 2008 is beachballing every few minutes or so for around half a minute. I trusted intel because of their name and I probably wouldn't have gone with their SSD if they had not been giving so much praise for their reliability. I'm very disappointed and will probably never buy one of them again. I was sure that they would fix this in no time, but it's been 3 months now! What the heck.

mikaelsoderberg May 10, 2012 2:41 AM (in response to YuriY)I have the same problem. It seems like this is not a priority for Intel, as such a substantial time has now passed since the launch of the product. I will never buy an SSD from Intel again as the general device compatibility support is inferior to, for example, OCZ.

9. Re: Intel SSD 520 and any Apple Macs with Nvidia MCP79 chipset BUG.
Alex May 26, 2012 4:23 PM (in response to YuriY)So, am I right that Intel won't fix this bug and I have to return my new SSD and replace it with OCZ or any other drive? I also have MBP 5,1.

10. Re: Intel SSD 520 and any Apple Macs with Nvidia MCP79 chipset BUG.
YuriY May 30, 2012 5:05 AM (in response to Alex)Intel have answered me. Intel will not fix that issue. So any users with Mac (Nvidia chipset) SHOULD not to buy Intel SSD based on Sandforce.

13. Re: Intel SSD 520 and any Apple Macs with Nvidia MCP79 chipset BUG.
lsi Aug 8, 2012 11:20 AM (in response to YuriY)I bought this product immediately after release, tested specifically for nVidia SATA2 compatibility (and confirmed it was broken, locking down to SATA1) and reported the bug to Intel. They were nice enough about responding to it, but they have done nothing to resolve it. This is nothing new for Intel, the 510 had the same problem and they never resolved it either. The 510 also won't perform to spec on AMD AHCI drivers, only msahci drivers which I have confirmed on multiple SATA3 platforms. My general rule with newer gen SATA3 Intel SSDs is that I will only use them on Intel SATA chipsets, because they have proven to be marginal in both performance and compatibility on non-Intel platforms. This type of firmware support is certainly not worth their price premium.
I run a 320 in the same system and it works perfectly with both SSC enabled and disabled. Some SSDs will work properly on nVidia SATA2 at full speed with SSC disabled, but not with it enabled--but a large portion lock down to SATA1. Most systems have no access to enabling or disabling this feature (Spread Spectrum Clocking), so this is basically a responsibility of manufacturers at a firmware level.
This is not a rare problem; a Samsung 830 I tested last night was unstable in either mode, and is basically unusable. A Kingston V200 wouldn't even detect until I used a different cable, but it also locked down to SATA1. The 320 worked perfectly with all cables, in all modes.
As much as these newer Intel SSD models are faster, in my mind nothing Intel has produced has been as refined of a product as the 320. Since I haven't seen them do anything to improve or fix these problems, I don't really buy any more 520s since finding this bug & lack of legitimate action to fix, and I probably won't buy 330s either as it's just another twist on the same architecture. I prefer using SSDs that get firmware updates like the rest of the industry (or that have utilities to work around these type of problems), as LSI/Sandforce themselves will probably fix this eventually. I'm an IT consultant who implements a lot of these.

lsi Aug 8, 2012 11:27 AM (in response to lsi)Recent Plextor products with current firmware sync properly on these platforms with SSC disabled; I reported the bug to them and they fixed it which I was impressed by. The M4 with their latest 000F firmware locks down as well in either mode on my test platform (non-Mac, ASUS AM2 motherboard).
