3 out of 5 eggsGood Performance, Low Durability

Pros: This drive, as do most SSDs gives great performance. My boot-up time was cut in half.

Cons: I purchased this 512GB SSD on 15 March 2013. I installed it on 3 April 2013. The drive failed 20 May 2014. No longer boots.

Other Thoughts: After I fully installed the new replacement HDD, I tried to use the Transfer utility thinking it would refresh the SSD and make it bootable again. But, I get nothing but errors.

4 out of 5 eggsUpdate to original review of 8/10/2012

Pros: VERY fast; MacBook Pro booted in 15 sec under Mountain Lion; now with Mavericks, about 10 sec. All operations are fast and fluid. Heavy Photoshop work and related are quick. Installation and data transfer were uneventful. See Other Thoughts.

Cons: Bad experience on purchase in 2012 (see review of 8/10/2012) but replacement SSD performed as it should. At present a subtle system flakiness (mysterious "Disk Removed Improperly" warnings in OSX, although all disks internal and external remain connected and mounted) has shown up. Investigation continues. See Other Thoughts.

Other Thoughts: This SSD has been great. Newegg and Crucial have responded without delay, both at purchase time, and at present with the flakiness that has shown up. Crucial's diagnosis is that the Mac, with "Stop Hard Disks When Possible" checked, is not completing its "garbage collection". I am following instructions to do power cycles and let a long run with no data I/O permit garbage collection to complete. I write this review in good faith -- will add an additional comment only if this maintenance leaves the problem unchanged.

I see in the comment policies that my discussion here may verge on what is discouraged, but I think it appropriate to note this: if the "garbage collection" is as important to disk maintenance in this case as it now seems to be, it is disappointing that Crucial and perhaps Newegg did not provide more documentation, in particular for Mac owners. Although that said, and having received detailed advice on how to proceed and on how to maintain the disk in good condition going forward, I can only compliment both Crucial and Newegg for their help and prompt communications.

1 out of 5 eggsFailed on first use

Pros: It's probably fast. The benchmarks say it's fast.

Cons: I connected it to a PC using the included Apricorn USB/SATA adapter. Everything seemed fine, until about 15 minutes into the copy it failed with write errors. The drive was burning hot, well over 120 degrees.

After disconnecting and reconnecting the drive, Windows would no longer recognize it. Another similar USB/SATA adapter didn't work either.

Now, when I plug the drive into the Apricon adapter, it emits a faint squeaking sound. So it's possible the Apricorn adapter destroyed the drive.

Other Thoughts: Unfortunately, I purchased this drive while living in China and it didn't get to me for a while, so I can't return it. Hope I can get a Certificate of Appreciation for making such a generous donation to Crucial.

5 out of 5 eggs

Pros: To those complaining about your crucial ssd dieing. Update the firmware. There is a bug that causes it to fail after a certain amount of boot ups.

While this should not be a problem it is, but after using 4 different manufacturers and multiple ssd's from each, Crucial is by far the fastest and most stable other than the shipping with broken firmware.

Cons: the broken firmware

1 out of 5 eggsDied after 3 months

Pros: Easy to install, quick, quality brand.

Cons: Drive completely died, doesn't even get recognized by computer as being plugged in. Plugged into other PC's, the same story. Unfortunately I lost all my data going back 3 months. One idea of SSD is moving parts so the drive doesn't crash. I guess that is no longer a viable selling feature since this drive just flat out died!! Really angry...will not by crucial again, will stick with Vertex and Samsung both of which have been flawless for me for years of use.

5 out of 5 eggsAwesome upgrade!

Pros: Easy installation. Super fast boot times. My MacBook Pro boots in about 8-10 seconds from a cold boot. I also added a 16GB RAM upgrade from Crucial. My laptop flys through every task. VMs in Parallels Desktop are a lot faster. Photoshop launches blazing fast. Everything runs super fast. I highly recommend this upgrade.

Cons: None. This SSD has been great!

Other Thoughts: For reference, the MacBook Pro that I installed this SSD into is a late 2011 MacBook Pro, 2.2GHz quad-core i7. It was very fast and capable before this upgrade, but after, it was like having a whole new computer. Adding the SSD and the 16GB RAM upgrade mean that I can hold onto this system much longer, and get a much beter resale value.

3 out of 5 eggsdead

Pros: fast for a boot drive, load my OS very fast. Loved when it worked.

Cons: star crashing on me, after running great for almost two months, unable to recover win 7 or re install OS. error oxcoooo225 the boot selection failed because a required device is inaccessible.

Other Thoughts: after troubleshooting with crucial tech support for two days they send me a RMA and UPS label to return for a replacement. Will see when I get the new drive.

5 out of 5 eggsGreat drive

Pros: The transfer kit was simple and worked great. No problem swapping out the drives. Very fast, 7.4 on windows 7 index (I know, that doesn't always mean much!). The software came with the next version up, didn't have to download the latest. That Cd/DVD was bootable and ran fine from there.

Cons: so far, none. I could wish for a mounting bracket for a 3.5 slot. That is all that was missing and I had an extra one.

Other Thoughts: I7 950, Asus saber-tooth, 12 gig ram - a pretty fast rig that includes 2 sata 2TB drives as well. I do video editing and need the storage!

5 out of 5 eggsGreat upgrade for my late 2011 MacBook Pro

Pros: Easy install (if you know what you're doing), very fast boot times, fast application launches. This model includes a really good SATA to USB adapter, and cloning software. I didn't need to use them, but they will be useful for other things. Although I have not used my laptop on battery for a full day, it appears that the SSD has improved my battery life slightly. My MacBook Pro has typically given me about 6 hours of run time on battery but the rate of battery use appears to have slowed a bit with the SSD installed versus the 7200RPM hard drive that I had installed before.

Cons: None so far

Other Thoughts: My only concerns have been related to garbage collection. When you delete files, the SSD marks them for deletion. Later, it performs "garbage collection" to finally remove the old data. At first, it was a little unclear on when this happens exactly. A process in your computer's OS called TRIM is supposed to tell the SSD to clean out the old data. For some reason, Apple has chosen to only support TRIM on their own SSDs. There is a third party utility that will turn on TRIM, and I installed it. It appears to be working properly. I later found out from Crucial tech support that installing TRIM support really should not be necessary. The SSD will use idle time to perform its garbage collection activities. I was really worried about the lack of TRIM support from Apple, but it appears that I may have been worried over nothing. This is not Apple bashing really. I'm sure they have their reasons. There may be some unique characteristics in their SSDs that I'm not aware of.

3 out of 5 eggsNot exactly 100% ...

Pros: Fast
Was around $300 at the time I bought it

Cons: Has locked up the computer several times
Some timing issues playing the Freecell card game

Other Thoughts: When you buy any drive, you naturally expect to have no issues with the drive or the computer, if it worked well with a regular hard drive, you should be able to run an SSD just as reliably.

I have tried to get this drive to run right by every tweak I could find online, and it still has some strange behavior at times. While it works correctly much of the time, the frequent strange behavior makes me think I will ultimately sell it and try something else.
