Intel 520 freezes on MacBook Pro/Mac OS X Snow Leopard

[idata]

Hi all,

I installed an Intel 520 SSD (240GB) in my MacBook Pro yesterday. After reinstalling the system, I moved my datas.

I encounter freezes! A few seconds freezes/hangs. Quite often actually.

It seems a bit random but it is really annoying! The whole computer is frozen.

I noticed it happens more often when a lots of datas are going in and out. Browsing the web doesn't do much things. Copying a file from a disk image (DMG) to desktop, it freezes… sometimes.

The SSD has the 400i firmware. I installed the drive in the HHD bay. Negotiated Link Speed is 6 Gigabit. MacBook Pro EFI is up-to-date. Software is up-to-date.

I haven't activated the "Trim Enabler" software (Mac OS X doesn't manage for 3rd party drives).

I cannot run the SSD Toolbox from my Mac. I'll try to install Windows and see if it hangs up.

Have you heard about these problems? What can I do? I don't want to keep a drive behaving like this!

Thanks for your help,

There's also a thread about the 330: /message/163142 http://communities.intel.com/message/163142

People experiencing exactly the same problem.

It's really a shame no one from intel is looking into this 😞

I have the same problem with 520 on Mac OS 10.8 (Mountain Lion), which makes using 520 counterproductive (it's beachballing all the time).

I thought it might be fixed by firmware update, but I couldn't find any references to current 520 firmware version, is it 400i?

Same exact problem here ... Intel 520 SSD running on a MacBook Pro Early-2011 15" 8,2. What's interesting is that when this happens I try to into "System Report" under About This Mac and when I click on the Serial-ATA section nothing shows up. All the other sections appear fine.

I do not have this problem, mine shows up allright and with correct info.
