From the Manufacturer

The Crucial m4 SSD

Award-winning quality. Award-winning performance.The award-winning Crucial m4 SSD delivers powerful performance gains for SATA 6Gb/s systems. Designed to empower your system, the Crucial m4 SSD offers faster application load times, faster boot times, and increased durability compared to a traditional hard drive. The results speak for themselves: blazing-fast sequential read speeds of up to 500 MB/s for any file type.

Cutting-edge technology. Quality component testing. Built with advanced controller technology, Micron proprietary firmware and high-speed synchronous MLC NAND, the Crucial m4 SSD is engineered to deliver consistent, blazing-fast SSD performance. From the extensive research and development that led to its ultimate design, to the hours of testing and validation spent on each NAND component, to rigorous compatibility testing in the Crucial Performance Labs to ensure component functionality, the Crucial m4 SSD is built to last.

Consistently fast speeds. No exceptions and no fine print. Theres a reason the Crucial m4 SSD has garnered numerous international awards since its launchit does what its supposed to do. No matter what kind of files youre working with on a Crucial SSD, youll experience high speeds with no drop in performance.

Unlike other SSDs on the market, Crucial SSDs treat all files the same, regardless of whether theyre compressed or uncompressed. This is important because the files most people use everyday videos, mp3s, advanced graphics files and zip files - are compressed files and thus unable to be compressed any further. While many SSDs on the market achieve faster speeds by using file compression, many of the most common file types cant be compressed, resulting in SSDs that often deliver drastically slower speeds than originally advertised. With the advanced technology of a Crucial SSD, however, youll never have this problem!

Crucialquality you can depend on. Crucial is a trusted name when it comes to SSDs, and thats no coincidence. As a brand of Micron, one of the worlds leading manufacturers of SSDs, we work with our engineers to design, refine, and support our drives. With over 15 years of experience in the memory industry, NAND component testing, and the ongoing development of advanced technology, we continue to innovate without sacrificing what has made us great: high-quality upgrades and outstanding customer service.

Crucial SSDs. Performance you can trust.

Not only is the boot time faster, but now opening programs is super fast.
Greg Acuff
This is probably the best upgrade aside from buying a whole new system that you can purchase to make your old system quick again.
gstboy
The boot up speed is so much better now and it uses less power than the old mechanical hard drive.

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.

Size Name: 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.

Size Name: 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.
