Product Description

Product Description

Award-winning performance. Tiny form factor.
The Crucial m4 mSATA SSD delivers all of the award-winning performance and reliability of the Crucial m4 SSD – in a drive that's an eighth of the size. Measuring in at about one-third the size of a standard business card (3cm x 5cm), the Crucial m4 mSATA is designed primarily for ultrathin laptop users who want to dramatically increase their system's performance. Featuring the same advanced controller technology, Micron custom firmware and high-speed synchronous MLC NAND that have made the Crucial m4 SSD a mainstay on the market, the Crucial m4 mSATA SSD is engineered to deliver the same blazing-fast performance as our award-winning 2.5-inch SSD – in a smaller mSATA form factor.</br>

Ultrathin form factor means flexibility. Because of its tiny mSATA form factor, the Crucial m4 mSATA SSD can do things that hard drives and other SSDs often can't. With the Crucial m4 mSATA SSD, save valuable system space by mounting it directly to the mSATA socket on your motherboard – and free up a hard drive bay in the process. Or just keep your existing hard drive and use the Crucial m4 mSATA SSD as a cache to accelerate the system's performance. Validated for Intel® Smart Response Technology and NVELO Dataplex™ caching software, it's designed to work as a cache or as a standalone SSD for ultrathin laptops. No matter how you use the Crucial m4 mSATA SSD, experience high-performance storage in a tiny, low-power package.

Consistently fast speeds. No exceptions and no fine print. There's a reason that Crucial SSDs have garnered numerous international awards – they do what they're supposed to do. No matter what kind of files you're working with on a Crucial SSD, you'll experience high speeds with no drop in performance.


Unlike other SSDs on the market, Crucial SSDs treat all files the same, regardless of whether they're 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 can't be compressed, resulting in SSDs that often deliver drastically slower speeds than originally advertised. With the advanced technology of a Crucial SSD, however, our advertised speeds are tied to real world use.</br>

Crucial - quality you can depend on. Crucial is a trusted name when it comes to SSDs, and that's no coincidence. As a brand of Micron, one of the world's leading manufacturers of SSDs, Crucial engineers work tirelessly to design, refine, and support a powerful line of SSDs.

    I've been using this drive in a Samsung Series 9 laptop for 3 months and it has worked perfectly every day. Read/write speeds have been good, it has improved performance over the drive that came with the laptop, and provided me with the space that I need.

    Unfortunately, the drive stopped working yesterday. The screen froze whilst using Chrome and I had no choice but to long-press the power button to shut the machine down. On re-boot, the laptop no longer recognised the SSD. Going through bios implied that it wasn't connected at all; an invisible drive.

    The first thing I did was to re-install the original SSD that came with the laptop. This was recognised immediately and allowed me to boot up the machine, proving to me that it was a disk fault rather than a laptop fault. I then did a few searches online and discovered a number of people who had experienced the same problem with this drive. The 1 star reviews on Amazon alight to the problem, which lies in the firmware that ships with the drive. If you experience a problem with a piece of software, or have a blip in the power supply going to the drive, it will freeze (or the SSD equivalent) and render itself invisible to the bios. Thankfully there is a solution which worked for me (and a few others) and has been suggested by Crucial:

    You will have to boot the laptop into bios (the first bios screen is fine) and leave it there for 30 minutes. You then power the laptop down and remove the drive for at least 30 seconds. You then insert the drive back in, boot to bios and leave it powered on for another 30 minutes. The advice from Crucial is that you should now remove the drive for 30 seconds and then try and boot the machine normally. I didn't have to do this.

    I just bought one of these to install in my new Lenovo Y500 (ordered at the same time). It's my first experience of using an SSD. As I write I'm using a laptop which absolutely flies along thanks at least in part to this device. I can't believe how quickly the laptop starts up and shuts down and applications launch in the blink of an eye. I've kept the 1TB HDD which came with the Y500 and am now using this SSD for OS & programmes and the HDD for the bulk of the data.

    I noted other buyer's warnings about the firmware revision and checked mine as soon as I had installed it and before cloning over my system partition. This was purchased on 5th June 2013 and the firmware was fully up to date - version 07MH. Installation was a doddle, simply plug it in and screw it down, and yes this drive comes supplied with two of the required screws (my Y500 only needed one of them).

    It's early days yet and I'm still in the process of setting up my laptop and getting my data transferred over etc, so I've not done any intensive work with it yet. I'm really looking forward to seeing how Lightroom responds with this baby to hold the catalogue. I would imagine I'll pop back to give some more impressions once I've been using this rig in anger for a little while.

    I bought this as an upgrade for 128 gb card on my Dell Precision M4600. I used an "Aleratec MiniPCIe mSATA to SATA SSD Adapter" and an external caddy to make up an external disk drive. I plugged the drive into the usb port, looked in "my computer" and it didn't appear. I did a whole lot of other things to try to make it visible. I went into the "Disk Management" in the "Computer management" bit of "administrative tools" in "Control Panel". There the disk was showing and I initialised it. I didn't go back to "my computer" to see if it was showing, at this stage, but went straight to Acronis True Image. It was showing there and I was then able to clone the disk. I replaced the old mSATA and the new one is working fine (although I have only had it a couple of days at this point).

    having bought a new laptop with built in 32gb SSD as a swap drive, realized for a none crucial storage these SSD's finally gives a chance to have a hard drive in to the same ball park as modern processors and memory.
    Fitted this as a primary hard drive and it really is fast, used the built in 500gb as storage with this drive having the operating system and programs on, windows benchmark score 8.1 on my system just beating processor and memory scores, impressive but time will tell if is going to last.

    I bought this to put in the Intel Nuc Intel BOXDCCP847DYE Desktop PC - (Celeron 847, QS77, DDR3, USB 2.0, 2x HDMI, Windows 8). I'm happy to say installation took only 30 seconds and it's working well, can't ask for much more really. I've only had it a couple of weeks so reliability remains to be seen, no problems so far.

    I forever find it amazing how things in the IT world constantly shrink over time. The Crucial M4 mSATA SSD is no exception. 256GB of fast solid state hard disk storage in the space of half a credit card. This SSD was purchased for a boot drive on a machine built with an Asus Maximus V Gene motherboard. The motherboard has a special mSATA daughtercard slot which should not be confused with a normal SATA port. If you need SATA (rather than mSATA) Crucial sell a M4 SATA 256GB also Crucial 256GB M4 SATA 6Gb/s 2.5 inch Internal Solid State Drive.
