Product Description

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.

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.


Crucial MX100 SSD img4
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.

Crucial MX100 SSD img5
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.

    When it comes to SSDs, you can't go wrong with Crucial. This is their MX100 line, which is intended to replace their M500 line (not the M550 line).

    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).

    Cheap and reliable. We buy quite a lot of these, and so far have had no issues. It isn't as fast as a Samsung 850Pro, but it is half the price and you would be hard pressed to notice the difference.

    Size Name: 256GB Verified Purchase
    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:

    BEFORE:
    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.

    Installation on my Dell XPS M1330 was straightforward.
    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.

    I replaced the drive in my mid 2010 MacBook Pro with this. Yosemite left the Mac struggling with the old drive, but this has made it feel pretty new again. Easy to install; open the back cover of the Mac, undo two screws, lift out the old drive, move four tork screws from the old drive to the new one and redo the steps in reverse order. Turn on your Mac holding the command (Apple) key and R at the same time. Wait until you see a spinning globe and it'll download and install Yosemite. Then you can attach your old drive via USB and use migration assistant to transfer your old stuff to your new one. You'll need a way of running your old drive - you can buy a simple case that lets you swap drives in and out for around a tenner - well worth buying anyway. I recently bought one that's designed for 3.5 inch drives; this new 2.5 inch SSD attached and worked just fine, although as it's not fixed in place is not a permanent home for the old drive. All in all the process took around ten hours; about five or six to download and install Yosemite and about four hours to transfer the old data (~130 Gb). I let most of it happen over night.
