Didn't mean to say "Oh Thanks" twice. The vendor from which I bought my Crucial M4 will allow me to RMA the drive for Store Credit, an exception. I have 6-days before my refund period expires to decide if I want to go this route. It's a nice gesture on their part but not exactly what I want. I want to purchase another SSD in advance, then be reimbursed for the M4 once they receive it. Therefore, I could straight from the M4 to the 470. The course that they laid out for me would entail swapping out the M4 for my slow stock HD then using that for a week while everything is processed and I'm given store credit. I'm beginning to think if I'd be best off just living with the M4, the beach balls are usually sporadic and well-spaced. Plus, software fixes may lie ahead, hopefully.

I'm going this same route with mine, just gonna wait it out.

I had mine RMA'd, Kingston told me the same your vendor they told you, except they didn't offer me store credit.

Lol, well you don't appear to have many options if they won't give you Store Credit. In the back of my mind, I knew, from the get-go, the second drive would perform like the first. Unless, of course, I got two defective drives, what are the odds of that?
 
My computer has been nearly unusable in the past 15 minutes. So many system freezes and beach balls. More the former. Ugh. I don't know what to do.
 
Sorry to hear about all your troubles Applegoat, I just got a 64GB M4 but its too early to tell if it is going to cause trouble in my '09 13in MBP.

Could it have something to do with the TRIM support?
 
I haven't enabled TRIM but I've installed the 512 GB M4 SSD in my 2011 MBP 15". After more than a full day of use both at work and at home I've had no issues at all. The SSD screams and I forgot how much I missed the quick loading of the OS and awake from sleep as well as how fast apps start. Loving it. I did install the 0009 firmware and did a clean instll of Lion. I have yet to decide about TRIM though. I started a thread about TRIM and would love opinions about how to enable it as I've read different things about the optimal way of enabling it on Lion.
 
probably a bit off topic, but I do want to share my positive experience with the Crucial 256GB M4 in my 2011 17" MBP

I got the drive installed by an Apple authorised servicer, a cost I was willing to pay because I'm not all that familiar with the inside of Mac's and wanted to continue to have Apple support if anything went wrong (of course, though, they wouldn't cover the drive.)

Anyway, the drive was installed and had firmware 0001 on it. A firmware that apparently isn't actually capable with the 2011 MBP, so i was getting consistent freezing of the machine, beach balls, and could not at all use the MBP. I was quite worried and not too happy. I then rang Crucial and made it clear I wasn't too happy about their product. they told me to upgrade to the firmware and I did, still no different. So, I thought their was no answer, and was wanting to get rid of the drive, but because I purchased it from eBay, Crucial would only do a store credit for me, in which was not appealing, because I didn't want anymore upgrades.
So i decided to give it another shot, and wiped the whole drive, and reinstalled lion.
Since then (3 weeks on), i haven't got one beach ball and this drive absolutely flies, everything opens up so quickly, and hasn't crashed once....now running on firmware 0009.

Hope this helps/encourages some of the followers.
 
Just checking in too, its been 2 weeks now, no beachballing on the 64GB model, no apparent negatives. Did the TRIM patch.

So far so good
 
I still haven't done anything about TRIM. Still undecided about how to do it.

In the meantime, I've updated the EFI firmware update and again, no problems whatsoever. NO beach balls or any other problems that I can mention. I am extremely happy with the M4. :D
 
512Gb M4 with 009 rocks. Received it with 008, and it would beachball constantly, but after the upgrade, not a single issue. Love it, fastest storage device I've ever owned.
 
Has anyone managed to get it to work without a SuperDrive? I managed to get it running thanks to some GRUB trickery, tells me my drive is eligible for an update and everything. It goes through the update process and tells me that the version is now 0002... and I'm most certainly using the 0009 disk image. What gives?
