5 out of 5 eggsPretty good

Pros: Just enough room for my software. It's fast and reliable. 2 years now an not a single issue for me.

Cons: Have to go into the bios setting and change some things to install OS.

Other Thoughts: Had the 128 gb version and wasn't enough space. This one is good but not enough room for games.I'll be upgrading too a larger ssd once the price goes down.

5 out of 5 eggsStill Going Strong!

Pros: Easy to install, reliable! Its been running flawlessly now for over a year (installed Nov 2012)

Cons: Pricey!

Other Thoughts: This was my first SSD and now I'm hooked. With some minor BIOS configuring I get a operational boot of 15 seconds using Win 7, SP1. I have my OS and my favorite games on this SSD. I don't miss staring at load screens in Battlefield 3/4 or Skyrim!!!

1 out of 5 eggsFast when it works, slow when it's a brick

Pros: Fast, easy to install.

Cons: Died abruptly after nine months of use in a home PC. It would only sporadically appear to the BIOS, and when it would actually show up, it was buggy and slow and over-run with errors, and then would just disappear again. It's a brick.

Other Thoughts: I dread going to Crucial to RMA this, but I must.

3 out of 5 eggsGood so far

Pros: Its an SSD,fast,small form factor,3 year warranty

Cons: Have had it not show up during boot 2 times,reset and it reappears,I don't use sleep mode, hibernate or defrag (which win 7 should turn off)

Other Thoughts: It was overpriced when bought, but i thought it was time to give it a try since i have always ran raid 0 setups and didn't like the idea of always having 3 hds, 2 for raid, one for back up.I'm a gamer and have never had it crash during play,because of the ssd itself.I have done 3 firmware upgrades which seem to slightly improve performance and reliability. Overall good so far.

5 out of 5 eggsSSD THAT WORKS!

Pros: Almost two months using this on windows 8 doing a clean install. This is my first SSD and the speed is amazing. Once you have your first SSD you will never go back to an HHD.

Cons: its time for a 1TB that everyone can afford, I am using 256gb because it was a reasonable price.

Other Thoughts: For the person on the fence, now is the time to try an SSD.

5 out of 5 eggsGreat

Pros: Even though my motherboard is not SATAIII it is still a big difference from a standard HDD. I am only running 224 read and about 212 write but its still blazing fast, just ordered a new GIGABYTE MB, I cant wait untill it gets here to see what this baby really puts out on SATA III.

Cons: NONE YET, Hope it lasts

5 out of 5 eggsVery Enjoyable Drive

Pros: Hasn't died. Increased battery life. Sped up my netbook like crazy. Vibration resistant champion. Quiet (lol). Pretty much instant on time out of standby or hibernation.

Cons: None.

Other Thoughts: I ride a motorcycle all over the place. I throw my netbook in my saddlebags and go. Used to always be worried about hard drive platter damage from all the crazy vibration it would have to go through on the road. When I decided to take a trip across the United States, I decided to upgrade to solid state and pretty much rule out vibration induced damage. Needless to say, this thing takes a pounding and keeps on humming. Even left my netbook on a few times, drove around for a few hours, and whipped it out only to find it happily chugging away at the desktop screen. lol. I love this solid state drive. I couldn't imagine what that would have done to a traditional hard drive. All my mobile computers will be SSD from now on. I've been using this one for almost an entire year now without a single problem. Crucial did nice.

5 out of 5 eggsJust Get One!

Pros: Easy Install, Fast Boot times, Good Size for the Price

Cons: I wish it was a little cheaper, but that's just greed on my part. I'm sure these will be a hundred dollars within a year.

Other Thoughts: I got this for my gaming PC. I just have the OS and a few games on the drive. Everything else is on a 500GB data drive. The PC now boots within 20 seconds of pushing the On button, recovers fast from sleep, and opens and closes games quite quickly. Makes me wonder what my system performance would be if everything was on SSD.

5 out of 5 eggsWorks great!

Pros: Built a new computer with this as my main drive about 6 months ago. So far it has worked great and boot times are amazingly fast. Game loading times are fast too! Path of Exile loads maps so fast that the loading screen doesn't even have time to appear!

Cons: I had a Crucial M4 go bad on my office computer ; makes me slightly worried about this one. Hopefully it will last.
