Crucial MX100 SSD img1
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.

    I bought one of these to replace the hard disk in my wife's 3-year old Samsung laptop. It's a reasonably specced machine with a Core i5 dual-core CPU, 8GB RAM and a 750GB hard disk but the boot times had been creeping up recently to annoying levels so, with the price of SSDs falling to sane levels, I purchased one of these. I chose Crucial having had a C300 SSD in my desktop gaming machine for the past 3.5 years with no issues whatsoever. My wife won't need anywhere near the 750GB that her laptop had originally being a typical home user so I judged that 256GB would do nicely.

    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.

    Worked great. If you plan to use the cloning software then make sure that the SSD is the same size as the hard drive being replaced or make sure you have software that can clone just a partition (the one you have the operating system on). The supplied software didn't seem to do this, could be me though. Win 7 needs a system partition of 100mb to work and Microsoft recommend that this partition is on same drive as the operating system so bear this in mind when installing because if you are leaving the Win 7 system partition on the old hard drive things will work but you are doubling your chances of failure because you now need 2 drives for everything to work. I bought a 256 SSD and kept the old 500 gb hard drive in place and went for a clean Win 7 install. Worked perfectly and disk installed the 100mb partition too. I reformatted the old 100 mb partition on the old drive in just case of conflict. Had a bit of a problem with Microsoft's 200 plus updates. It got so far and then wouldn't configure. Guessed that it was a time out problem so installed the updates 50 at a time without problems. Now have a lightning fast i5 machine with 16 gb RAM. Now that MS says it will give Win 7 users Win 10 free I don't think there's any more I can do for my pc. Product once installed works great. Please read about the problems I and other users have had with wrong size screws being supplied with adapters if you want to put the 2.5 SSD in a 3.5 bay in your pc. Laptop replacements should be ok.

    I have a much loved (used daily) but ageing Dell Inspiron 640m E1405 laptop which must date back to 2006. Has a SATA 1 hard disk controller on a 150gb HD. Intel 945GM chipset. 2gb RAM. Its built like a tank but sadly was struggling to cope with the demands of modern life.

    I thought about spending money upgrading the memory from 2gb of ram but when i ran the memory scanner it recommended this SSD drive. Everything I read said it would not run a SSD very well due to its age and there may be BIOS issues etc etc. But had to give the old girl a chance and took the plunge.

    Crucial drive comes with licence for True Image from Acronis to clone the drive but I also purchased their SSD upgrade kit which provides all the leads and a spare case to turn the old HDD into a portable drive. Probably dont need this is you know what you are doing and have the correct leads but this helped me. I had terrible problems getting the drive cloning to work from within windows but read that it is more reliable using a boot disk version created within True Image to USB. I did this and it cloned first time in about 15 minutes. It allocated the extra storage equally across the 2 existing partitions which was fine.

    My new SSD fitted perflectly in the cradle with the 4 existing screws. I then fired it up and held my breath and to my amazement it started perfectly. Windows loaded and all my programs and files were there. It needed one reboot to settle everything into place and now works perfectly just as before but feels slightly quicker but a lot more stable.

    In terms of speed then it is not a massive improvement. The drive is read/writing about 125mb/s which is roughly a quarter the speed you would expect from sata 3 but it feels like a much more stable machine.

    I purchased this for my Apple MacBook Pro (MBP), Late 2011 model just over a year ago. It's done wonders, my MBP will now boot up within 12 seconds. File transfer speeds are also a lot more impressive than the standard HDD which it came with.

    I have conducted a test to display the speeds which I receive on my Apple MacBook Pro, before posting these results I also tested the SSD in my Windows PC and the results are identical. I used the Blackmagic Disk Speed Test to conduct these results.
    - Highest recorded read speeds were 570MB/s
    - Highest recorded write speeds where 331MB/s

    *Please bare in mind these disk speed tests are after using the SSD for over a year - so they are very impressive.
