Bought Crucial M4

mine... after that the m4 reached also a reading speed of 501mb/s

 

Im guessing you bought the 128GB right?

If you bought the 256 or 512GB, write would be faster but whatever.

Yes, it is fine.
Mine boots around 12~15 sec as well.

But my write is 210 and read is 510.

 

1) I didnt and runs great.
2) Nope, but I still have right r/w speed.
3) iTunes, just transfer whole Music folder
4) Music is best to go with the SSD. iPhotos or photos can be saved on Optibay.

 

Good choice on the M4, I love mine. I did enable TRIM. Does it make a difference? Don't know but I certainly feel more comfortable with long term performance with it though. Mine came with the latest firmware and yours like did too. For iTunes I just dropped my music in the folder and it added just fine.

 

Try copying the whole folder of itunes under "user/library/itunes"
to your new SSD's "user/library/itunes"
This should replace all the stuff in your iTunes.

 

I have the M4 as well, only I see much faster startup times. I hit the power button, about 1 second for the Apple logo to appear, the spinning wheels lasts maybe 1 second, and shooted to login screen, so about 6 second bootup.

I am super impressed with the drive.

 

I received my M4 this last week also. I just finished superduper cloning this morning and installed it today. I expected it to be faster, but not this fast. This old 2009 MBP feels like my 2011 MBA.

I did not enable trim. According to Crucial, the M4 has its own garbage collection that will run when the drive is idle. I also downgraded my firmware to 0309 as recommended by Crucial.

 

I recently fitted the 512GB M4 to a mid 2010 MBP and it would not cold boot with firmware 000F but is now fine on 0309. The crucial site has lots of forum chatter about issues, but I couldn't find a clear recommendation.

 

I just got a 256GB M4 and I love booting up in 9 seconds.

 

^ this.... I have used my M4 without trim for several months now without issues. I am also using 000F firmware without issues. I also asked a crucial rep if I should downgrade the firmware and he said absolutely not. He said downgrading the firmware is only recommended for a windows computer.

 

i grabbed a 512 version of this 'drive' and i'm pretty happy. i enabled trim.. don't know/don't care if it does anything - laptop is plenty quick now.

price was great compared to the [albeit superior] samsung830 of the similar capacity.

 

My 128GB runs firmware 000F but works great for me.
My SSD reads and writes at the same speed as when I got it and still boots under 15.

No beachballs after I switched to this baby.

 

Is this because the most up to date firmware (OOOF) does not play well with pre-2011 MBP's? Just curious, how did you downgrade the firmware? Download an older ISO image from Crucial, then burn it to a CD or USB and boot from it?

 

There's no direct quote from Crucial where they recommend staying on 0309. What there is, however, is a lot of Mac users claiming that they have beach balls or momentary freezing after updating to 000F. A moderator states what the difference between 0309 and 000F and basically says if you don't need "SAS" support, there's no reason to update.

People were then concerned about downgrading and losing their warranty. A mod posted saying it is ok to download from 000F to 0309 only:

So, from all that I figured I'd be best with 0309 to start with and flashed mine before copying my data. If 000F works for you, then the old saying, "if it isn't broke..." comes to mind.

 

0309 Firmware

Downloaded crucial-03093l.iso - copied to disk, booted into DOS/Windows included on the disk and installed.
