The Choice Between Speed and Capacity is Over -- Choose Both
Traditionally, SSDs have offered powerful speeds and extra features, but at a high cost per gigabyte. Enter the Crucial MX100 SSD. Leveraging years of R&D and NAND technology, the Crucial MX100 offers a low cost per GB, combined with unrelenting performance and one of the most complete feature sets available.
Micron Quality -- a High Level of Reliability
As a brand of Micron, one of the largest flash storage manufacturers in the world, the Crucial MX100 is backed by the same quality and innovation that has produced some of the world's most advanced memory and storage technologies. With more than 1,000 hours of pre-release validation testing and hundreds of SSD qualification tests, the Crucial MX100 has been thoroughly tried, tested, and proven. Make the switch to the Crucial MX100 SSD and start outlasting and outperforming your hard drive.
Feature-packed Capacity. Proven Reliability
The Crucial MX100 provides plenty of cost-effective storage for your photos, music, videos, and documents -- all while backing your data with a higher level of reliability than a hard drive or competing SSD.
Note:1 GB = 1 billion bytes. Actual usable capacity may vary.
Run Your System for Longer -- using Less Power
With Extreme Energy Efficiency technology, the Crucial MX100 is up to 89% more energy efficient than a typical hard drive.*
* Hard drive active average power use based on published specs of 1 TB Western Digital Blue WD10JPVX internal hard drive. According to NPD data published February 2014, this was one of the most popular hard drives available and an accurate reflection of a common internal hard drive.
Attain Consistently Fast Speeds without Compromising the Reliability of Your Data
Engineers created RAIN technology to protect your data at the component level, similar to how RAID is used with multiple hard drives. This enterprise-class technology increases the security and protection of your data to a level that's rarely available in consumer-class SSDs.
Keep Your Memories, Photos and Files Safe
When a photo or file gets corrupted, it often becomes unusable. Prevent this from happening in the first place with the Crucial MX100 SSD, which arms every storage component with four layers of Exclusive Data Defense to guard against corrupt files.
Push Your Drive to the Limit and Avoid Overheating.
Adaptive Thermal Protection technology enables the Crucial MX100 to dynamically adjust storage component activity based on how you're using the drive, allowing your system to stay cool and react to changes in use.
Do More -- Faster
Get true 550 MB/s sequential reads on both compressible and incompressible data -- and leave your old 177 MB/s hard drive in the dust.**
**Performance level based on comparative AS SSD benchmark ratings of 512 GB Crucial MX100 SSD and 1 TB Western Digital Blue 7200 RPM hard drive (WD10EZEX-00U). Actual performance levels may vary based on benchmark used and individual system configuration. Test set-up: Intel DZ87KLT-75K motherboard, Intel i7-4770K 3.50GHz processor, BIOS Rev. 0446, and Windows 7 Ultimate 64-bit operating system using AS SSD test suite.
Save and Transfer Files in Seconds Rather than Minutes
Native Write Acceleration technology spreads the drive's workload across several elements, enabling you to write data in seconds rather than minutes.

You should note that the performance on the 128GB, 256GB and 512GB models are different and at the time of writing, I believe the descriptions on the Amazon page are incorrect.
All variants have a 550 MB/s sequential read, but they have different sequential write speeds; the 128 GB SSD has 150 MB/s. The 256 GB SSD has 330 MB/s. The 512 GB SSD has 500 MB/s. Real world measurements may differ, but those are the numbers you should see. You can get proper, more detailed numbers if you search for reviews on reputable sites such as Bit-Tech or AnandTech.
In terms of performance compared to other SSDs, this is pretty much neck-to-neck, making it a great value for money, so whether you're going for a low, mid or high end build, this will do the job just fine. Also, I have bought this in addition to an M500 480 GB SSD, its 'predecessor', which it does outperform slightly.
One of the main reasons to get an SSD is to improve your experience with your laptop/computer. So while different people may get different boot-up times, it's the wrong thing to focus on. You only reboot a few times a day (at most), but you use applications and read/write far more often than that. It doesn't matter if your computer boots up in 8 or 10 seconds, what matters is that your applications load faster than before. In terms of the big ones, these are Photoshop, Lightroom, Visual Studio, IntelliJ and SQL Server and all of them benefit from the performance improvement. (Actually, you may get misleading and overly-optimistic SQL query times on your SSDs and may want to do a proper performance profile when deploying).Read more ›
Rather than cloning I used the more secure Backup / Recovery approach described in the include Acronis software users’ guide. I used a Western Digital My Book Studio for holding the backup. As this SSD had a bigger capacity than my existing HDD’s 320Gb, I had no need to shrink or omit anything
This worked well once the SSD had been initialised so that it was recognised by the system. This was not clear from the stand alone step by step description of the Backup / Recovery process.
My laptop running Windows 7 32bit now comes out of hibernation mode in a couple of seconds – very impressive & the SSD measured performance is now close to the Windows maximum. Subjectively it seems to have produced a much greater improvement in speed on this laptop than a previous in stallion of a similar but small SSD on my Windows 7 32 bit desktop. Not sure why – might be related to the amount of RAM 16Gb in the Desktop cf 4Gb in the laptop
The capacity of this SSD is easily sufficient to hold all my system, application & data files.
Overall I’m very satisfied.
Anyone using Win 8.1 who follows the advice on the Crucial website, downloads the free version of Acronis TrueImage 2014 that Crucial make specially available to purchasers via a slip in the packaging, installs TrueImage on their current hard disk, then uses it to clone their current hard disk partitions on to the MX100 may be in for a surprise when they then boot from the newly-installed MX100.
In some cases (mine included) the system will boot (pleasingly quickly) and appear to run without hassle... for a while. But then, without warning, it starts to seize up in a very strange way. Applications load and start up as normal, but any attempt to select from their menus produces no response. You still (for a time) have control of the mouse and keyboard, and you can go to your desktop and try to start any other application, which will also duly load, put up its opening screen... then refuse to do anything else. Once you've tried this with a few different applications, you find that you no longer get any response from the keyboard. You can still move the mouse, and use it to select areas on your desktop, but aside from that, no mouse clicks have any effect. You now have an unusable desktop, with no way of getting to the Task Manager to attempt to close any applications or reload Explorer. Your only way out is to force a power off.
If you go to Crucial's user forums you will find many Win 8.1 users complaining of precisely this behaviour over the past several months.Read more ›
The laptop only has SATA2 on board so I chose the MX100 over the slightly more expensive and slightly faster MX550 and I used the bundled Acronis software to clone and shrink her existing Windows 7 installation. The whole process was easy and took around an hour to transfer around 120GB of data (using a 2.5" USB drive kit that I bought separately). After a couple of false starts due to the boot information not being written properly, which I fixed using a windows recovery USB stick, the laptop's absolutely flying now.
In the spirit of trying to be scientific about it, I noted the Windows Experience scores and Crystal Diskmark benchmarks before and after installation as well as measuring the elapsed time from 'off' to arriving at the Windows password prompt...
...and here are the results:
The Windows Experience score for hard disk performance increased from 5.9 to 7.9 (the maximum for Windows 7).
The Crystal Diskmark scores were:
1000MB sequential read: 73.16MB/s
1000MB sequential write: 65.23MB/s
512KB read: 19.87MB/s
512KB write: 20.53MB/s
4KB random read: 0.273MB/s
4KB random write: 0.Read more ›

I have had this for a little over a year and it has decided to stop working. For a product that costs what it does I would not expect it to fail after 15 months. Very disappointed.Published 27 days ago by Client d'Amazon
