5 out of 5 eggsGreat for Hack's

Pros: Using in my Gigabyte Z77 Hackintosh.... Super fast Boot's in 3.7 sec cold boot, restore boot under 2....

Cons: Worked for a week to boot direct from it and can't make it work... So have a 1 gig USB as my bootloader, and this work around is just fine.

1 out of 5 eggs

Pros: Not any!

Cons: My pc will not recognize the drive. Have tried it on other machines. Contacted Crucial support. Tried their solutions but did not help. Contacted them again and got the run around. Paid a lot for this and it is DOA.

1 out of 5 eggsIt was AWESOME... for 4 months...

Pros: Never had a problem with it until now. It was blazing fast!

Cons: It lasted a few months!

Other Thoughts: I was using my laptop and suddenly noticed that I couldn't open any programs. About 5 minutes ago it had booted without a hitch and now it isn't even detected in the BIOS.

5 out of 5 eggsRemarkable Drive.

Pros: Fastest drive I've ever seen, and mSata means I can keep using the 1tb platter drive for storage on my laptop. Absolutely love this drive

Cons: None. Would love for it to be cheaper, but that's true of everything.

Other Thoughts: It amazes me that there aren't more high end laptops with quality spacious SSD's like this.

5 out of 5 eggsRunning for 4 months with no problems

Pros: I installed this drive on a Samsung Series 9 Windows 7 Pro laptop about 4 months ago. There were no problems whatsoever during installation and the drive has been running flawlessly. I didn't benchmark the drive, but performance is obviously much better than a HDD, with Windows starting in just a few seconds.

Cons: None.

4 out of 5 eggsWorks very well

Pros: *Got it on a great New Egg Deal
*Seems to operate at the max of the PCI-E 1.0 slot the Msata -> PCIe adapter from MacSales can function (which is about 250MB/s-300MB/s
*Firmware is produced for these Msata M4 units but this one already had the latest on it
*No hickups so far

Cons: *Longevity is always an unknown

1 out of 5 eggsWill not boot

Pros: It does work with newer normally used devices...

Cons: With the ASUS EEE SLATE EP2121 it will not boot at all, sometimes it does then it does not. I worked with crucial support and even purchased another 256msata and the second one performed the same way. Crucial also RMA one of them and said they would repair it, only to send me back the very same problem. It will not boot up in an ASUS EEE SLATE EP121 at all.

Other Thoughts: I am not sure if it is the ASUS EEE SLATE EP121 but I have the stock sandisk and it boots great 64GB. I just wanted 256GB instead of the standard 64GB.

5 out of 5 eggsFast and works

Pros: Installation: They included screws, which is unusual for a product like this, and a nice convenient touch.
Speed: I wasn't able to get my OS transferred to this drive, so I can't speak to that, but I was able to get some of the programs I want to see load up faster moved to it. The Adobe suite loads in seconds. PHPStorm loads in seconds (It takes over a minute to start installed on my hard drive). My games load in seconds.
Reliability: Wasn't DOA, and didn't find any bad storage blocks when formatting it.

Cons: None so far.

Other Thoughts: Couldn't get the OS moved over to it without downgrading from EFI to legacy boot, so I haven't bothered yet. That's really a problem with Windows 8 OEM installs, not this unit. Eventually I might try it and will update here if and when I do.

5 out of 5 eggsJust wow...

Pros: Bought my first laptop that supports mSATA, a Lenovo Y500, and let me tell you something...
Great amount of storage for my needs (and most people's needs)
Reduced weight to laptop by being able to remove laptop HDD
Increased Battery life
MOST IMPORTANTLY: My computer boots, to the homescreen, in 12 SECONDS.
Always go SSD.

Cons: Absolutely no cons here

Other Thoughts: None
