5.0 out of 5 starsMade my old laptop lightening fast
By David D. Arnold on August 5, 2011
Size: 128GB
Test Laptop - Dell Latitude D630 - 2.0GHz core 2 duo with 4GB ram
I installed this drive and then installed Windows XP pro. When complete I then installed Windows 7 home premium and set laptop up as a dual boot system. I then tested both by booting into Windows XP and Windows 7. I then ran every update and every service pack on both Windows XP SP3 and Windows 7 SP1. I installed antivirus, adobe reader, Microsoft Office 2007, Firefox 5.0, etc. When all was perfect with both operating systems I pulled out he HD and cloned it over to a brand new standard SATA drive. Then came the fun of testing both HD's and OS's for boot times, etc.
----------------------------------------------------------------------------------------------------
Pros: $2 per GB is a great price. Drive will breathe new life into ANY PC. Easy to install, lots of fun. Drive has NEVER locked up for me, not with hibernation, sleep mode anything.
Cons: $2 per GB is a lot higher than a standard SATA drive. Firmware was hard to locate, although easy to install.

5.0 out of 5 starsWorks great in 2011 Macbook Pro (and mid-2012 MBP)
By J. Z. on August 30, 2011
Size: 256GB
I originally wrote a glowing review about this SSD which I purchased about 6 months ago and after updating this review so many times it became cluttered. I still stick to my 5-star review but I'm going to reorganize this review for the sake of everyone else out there.

Before I get started, this review is for the 256GB model. The Sequential Write speeds (as advertised by Crucial) vary between the models:
64GB model: 95 MB/sec; 128GB model: 175 MB/sec; 256GB model: 260 MB/sec; 512GB model: 260 MB/sec.

This drive was installed in my current 13" Macbook Pro and I have had excellent results. After 6 months: No hang ups; no problems going in and out of sleep; everything is SO much faster. Bootup is less than 30 seconds; Firefox opens nearly instantly; About this Mac loads instantly; Disk Utility permission repair runs in under a minute; multitasking is smoother; just overall snappiness. The first thing I showed to a friend when he scoffed at the price was to open every single app in my dock at once (multiple browsers, the CS-3 suite, final cut, all of the iLife programs, LibreOffice). While on my old HDD I probably would have sat there loading forever, this time I didn't even get a pinwheel. Even my websites would load quicker. I've noticed my system backups are quicker when writing to an external harddrive using a Firewire 800 port, and my DVD ripping is about 15% quicker.

I always see people saying that a huge benefit of an SSD is better battery life. I've noticed almost no change in real world usage although I'm sure there is a minimal difference. Don't expect your battery life to change dramatically though. My computer is significantly quieter (and has less vibrations) which is very nice when I'm watching a movie late at night.Read more ›

3.0 out of 5 starsWARNING - Built-In Defect - MUST UPGRADE DRIVERS!
By Biz Person on November 1, 2012
Size: 256GB Verified Purchase
I bought this SSD and made it my boot drive, and it worked wonderfully at first.

After 6-9 months, my computer started to crash. It was an intermittent Blue Screen of Death (BSOD) about once per hour. (If you disable autoreboot, or snap a quick photo, you can see error codes on the BSOD. Mine included STOP: 0x0000007A and also second parameter 0xFFFFFFFFC00000C0 which I include here only in case someone finds this post by search term.)

Unfortunately if you go to Microsoft and look up "How to Fix BSOD", they give you a list of five or six things to try, all time-consuming and none helpful here. I was about to throw away my PC.

It turns out that the original firmware of this SSD drive has a usage counter that counts up to 5000 hours of use, and then starts counting usage by hour. The counter resets once per hour and it is bugged and that will hard crash the machine! Going to the manufacturer website to download the new firmware takes less than 15 minutes and fixes the problem completely.

So everyone who has ever bought this SSD MUST update the firmware immediately, or suffer a nasty disabling of their PC that takes many hours to figure out.

NOTE: About a year after writing this review, Crucial had apparently made the change on all shipping products, and I upgraded them from 1-star to 3-star.

5.0 out of 5 starsExcellent product
By H. Singh on June 7, 2011
Size: 128GB Verified Purchase
I purchased this product for my Asus U36JC-B1 which is the super slim notebook offering from Asus. The speed on this laptop is already very good, but I know with the 500gb SATA at the heart of it, slow down would be inevitable. So after purchasing the Crucial C300 for my HP DV7-2040us I decided to pick up this newer model for my Asus. I cloned my original 500GB SATA drive to this using Acronis True Image 2009 and a external USB 2.5" case. Acronis adjusted the partitions so everything fitted perfectly, including the recovery partition which are critical on these drives considering there is no optical drive.

I also made sure all setting were adjusted in Windows 7 64bit to account for the new drive, including disabling defrag and indexing, enabling TRIM, and if need be disabling LPM in the registry. Make sure you download the latest Intel Rapid Storage Driver, this can have a dramatic impact on speeds and how the drive is handled by Windows.

Intel Rapid Storage Driver: [...]

I am not disappointed with this hard drive, here's why:

Boot times are much quicker,
Application response is very quick,
No unreliability issues (thus far),
Battery life appears to have improved,
Switching from steel to plastic makes it slightly lighter,
Easy to install, remove your old SATA drive and plug this one in, easy!,

Installing one of these is like having a new laptop (in my opinion) the speed increase is dramatic, over and above a CPU upgrade.

I'm not trying to be a poster boy for Crucial but I am so impressed with these drives, I purchased another 2! 1x 128gb and 1x 64gb M4. I have a total of 4 Crucial drives running in different computers.

I highly recommend this product.
