So tell me, someone who is asking about SSDs on a forum is going to pay $700 for an SSD that they can't determine the performance gains from the $400 one?
Got a tip for us?

Then why did you ask what I was smoking?
First I tell you what my M4 speeds are, then you act surprised and finally agree with me. 😕

I was responding to a drive that had write speeds of 90MB/s....if you can't tell the difference between 90 and 400 I think you have bigger problems then just being a forum troll.

Funny, none of my M4s have a write speed of 90MB/s. They all write nearly 300MB/s. The one you're referring to must be defective. It would be helpful to acknowledge that possibility instead of suggesting a much more expensive solution.
A heads up with the M4 512.
I've bought 2 and both have failed. They failed in the exact same way, so these have a serious issue.
The good news is that customer service in Crucial is very good, so your covered. But drive failures are not something you want.
Note:
The two 512GB drives i've been using were swapped out a lot. Another M4 I use (256GB) is not (stationary). The stationary drive hasn't failed. But this is mostly irrelevant (just thought i'd mention it).

How long have you had it? Are are you swapping often? ( i.e. portable drive use)
Swapping may be the issue. I don't know. But conceivably, it's causing it, as after about 20 reconnections it fails to partition. This might suggest that this specific type of power change may be stressing it. Don't know

My M4 has been in my 2012 MBP for about a month and it has no issues. Writes about 258 meg/ps and reads about 421 meg/ps and it's about half full.
That works for me.

As has been also pointed out multiple times, this is incorrect information posted by Amazon.
Crucial's website has the correct information: http://www.crucial.com/store/partspecs.aspx?IMODULE=CT512M4SSD2
Don't toss around the word troll without actually knowing something about the subject at hand.

You're special. You take one single Amazon (albeit incorrect) spec and consider it fact, especially when this proves you wrong. I wouldn't be surprised if you read the Bible and considered it science.

Hope you guys don't mind but can I ask a related question?
Anyone running the M4 512gig in the optical bay of a 2011 MacBook Pro? The information on this is a bit Sketchy so want to find people with practical experience.
I understand that you are most likely going to only get SATA II speeds but what I'm not so clear about is the reliability of the drive in the optical bay.

Depends on which 2011 MBP you're referring to. Early 2011 MBPs have 3 Gb in the optical bay, late 2011 MBPs have 6 Gb in the optical bay.

Not that long, but it's an internal drive, not external so I don't have any "swapping" out. I don't know why you need to repartition the drive every so often though...
My friend, who bought my first 256GB SSD for like $700 bucks, still has it running and this was back in 2008/2009. Still running 3-4 years later lol.
I didn't need to reparation it (them) until I got a: "You need to Intitialize" message. Then I do that (losing everything), it initializes, but it won't erase or partition successfully (bricked drive).
In other words, I'm tooling along with one in an external case hot swapping on USB ports and Thunderbolt ports, then all of a sudden I plug it it and it gives me that message. So it could be that they don't like to be portable drives....or something (probably way off here, but WTH)

I've noticed on external drives, even my regular hard drives has that issue but usually unplugging and replugging it in fixes it after a while. Maybe give that a shot? Perhaps its an issue with the external enclosure itself?
Got Cruical 512 GB SSD
After a long thinking, I got Cruical 512 GB . It will arrive in 2-3 days. Can't wait to play X-Plane 10.... 🙂
Soon i will changing my signature too ...🙂

This is the drive I bought for my Late 2011 MacBook Pro. Although it may not be the fastest SSD in the universe it still blows away the stock HDD. I think for the money because of its size (512GB) its a great value SSD. Drive speed based on Blackmagicdesign Disk Speed Test is 264MB/s Write 513 MB/s Read. Windows 7 through Parallels scored 7.6 which I believe was the same via Bootcamp.
Good advice. Unfortunately, when this happens I've tried everything, including power cycling. They are dead, dead, dead.
Again, Crucial is great with exchanges so i'm still into these drives as they are very cheap, relatively.
But what about the reliability (I've heard it's not very good but haven't heard that much) - anyone know?

SSD, like hard drives, have a limited amount of hard shutdown counts. Perhaps you're not ejecting as you should before unplugging. That will kill any SSD or HDD easily.

That sounds about right. Mine's nearly 15 months old now but still giving those numbers. Glad it worked out 🙂
