New interfaces and multi-tasking demands require more from your system than perhaps ever before.

From its nearly instantaneous boot times, powerful data transfer speeds, increased multi-tasking capability, and rock-solid reliability, the Crucial M500 delivers dramatic performance gains--all at an affordable price

For Business | Secure Your Data. Protect Your Customers' Privacy

Your data is your competitive advantage. Whether it’s the inside information on your latest product or your customers' credit card numbers, information in the wrong hands has the potential to devastate your business. The best strategy for protecting your sensitive data is to implement a defence that includes top-level hardware-based encryption.

The Crucial M500 SSD is a self-encrypting drive (SED) based on the rigorous standards established by the TCG Opal specification. Combined with applications like Microsoft BitLocker or Wave Systems EMBASSY Trust suite, our AES 256-bit hardware encryption engine (that’s integrated into the controller of the Crucial M500) allows the drive to operate at full speed without the performance loss that’s typically associated with non-SED drives using software-based encryption technology.

For All Users | Consistently Fast Speeds. No Exceptions

No matter what kind of files you’re working with, on a Crucial SSD you’ll experience high speeds with no drop in performance across different file types. Crucial SSDs treat all files the same, regardless of whether they’re compressed or uncompressed. 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 slower speeds than advertised. This is important because the files most people use every day - videos, mp3s, advanced graphic files and zip files - are compressed files and thus unable to be compressed any further. With a Crucial SSD, the specs we advertise are the same specs you’ll see in the real world.

Crucial SSDs. Performance You Can Trust

Crucial is a brand of Micron, one of the largest NAND manufacturers in the world, and we design and develop our SSDs in-house using state-of-the-art technology. This means: hundreds of SSD qualification tests, more than 1,000 hours of pre-release validation testing, 1.5 billion dollars invested in R&D, and more than 30 years of industry expertise. We’re dedicated to quality and your SSD has been designed with cutting-edge technology and has been rigorously tested and approved. Don’t settle for anything less.

Having worked my VAIO SR Series into the ground over the 3 years I've owned it, I decided to replace the HDD with an SSD to breathe some new life into it. At first I was a little sceptical about how much of a difference this would make, but I can honestly say that the M500 SSD has made a world of difference to my laptop. The startup time has been cut from about 90 seconds to only 20, programs start almost instantly, and the computer runs Adobe CS5.5 Master collection without even a hint of difficulty, something I could only have dreamed of before upgrading.

In terms of installation it was extremely easy, I purchased an OCZ upgrade kit with the M500 which gave me the necessary software, cable and enclosure in order to do a clone of my HDD. None of these items were included in the box with the M500, so you'll need to get them from elsewhere as I did. To clone, there's just a few easy steps:
1. Put the SSD into the enclosure and connect it to your computer using a USB cable.
2. Run the cloning software and select the source and destination drives
3. Sit back and grab a coffee while it clones the whole contents of your HDD, this takes a little while!
4. Shut down your computer and remove all power sources including the battery, remove the back panel and swap your HDD and SSD over (you'll probably need to find some instructions from your manufacturer on how to do this correctly)
5. Start up your blisteringly fast computer!

You can then use your old HDD as an external drive, or if you have any spare bays, as a secondary drive in your computer.

In summary, the M500 is an SSD that oozes quality both in its construction, as well as in its performance. It pulled the Hard Drive rank on Windows experience index up from 5.4 to 7.7 and has made a huge difference to my computing experience. I simply can't recommend it highly enough!

Before tossing away your ageing laptop, you might want to consider upgrading to an SSD. This could work out as a much cheaper option considering that the decreasing prices of SSD drives. I do feel that SSD drives in general are still slightly overpriced when considering the fact that these are now mainstream and no longer belonging to a niche market. Yet to be fair, it could still work out much cheaper than buying a new laptop or desktop computer.

The Crucial M500 is definitely a proved and tested, fast and very reliable drive. It is not the fastest SSD, yet it makes up for that in the reliability department. After all what is the use of having a blazing fast SSD if your data could be compromised. The controller houses an numerous capacitors, so in case of a power failure, there is enough juice stored to write the otherwise lost data. Another crucial factor is that the drive is fail operational. This means that if a single nand fails, the drive will still remain functional. On many SSDs if a nand fails the whole drive fails. This technology is referred to as RAIN (Redundant Array of Independent NAND) or "cross-die redundancy". (It has to be noted that SSDs use nand flash to store data).

+ Very fast and reliable drive
+ Super easy installation
+ Light on batteries (great for laptop use)

Cons: (Applies to all SSDs due to the large number of writes)
- In order to achieve longer drive longevity, indexing should be turned off

I have not disabled indexing on my drive. My system is on 24/7 and the drive has been installed well over a year ago. Drive performs flawlessly.

○ To use the drive to its full potential, AHCI Mode must be enabled in the bios, and motherboard should support SATA 3.

I bought this from Amazon in November 2013. It really made a difference to the start up time, so I was very happy with it.

BUT after a while, I noticed that one regular activity - the automated look through the list of installed packages to see if any had available updates - became very very sloooooow. If I did it after booting, the progress counter would get to 100% in a blur of digits. But after a few hours, it would be as fast as a quick count, and after a few days, it would take many minutes and I could start it, go off to have a meal, and it still wouldn't be finished when I got back.

I started filing bug reports about this, thinking it was the system software that was the issue. Other people had the same problem and, when they gave details, many of them had Crucial SSDs too. Hmmmm.

This was one of a number of things have convinced me that, no, it's the drive that is quick each time it is rebooted, but then becomes increasingly slow, with read speeds dropping to 1% or less of what they were. It turned out that there's an update to its firmware which has amongst its evasive list of changes fixing some unnamed "issues" and I did a rare reboot into Windows to install it. That didn't help either.

So today, I contacted Amazon. I was expecting to have an argument (erm, 'discussion') about the way it was defective when it was bought so I should be able to return it for a refund long after the normal 30 day period had expired. I was very pleased when a full refund was offered very quickly, almost as soon as I said what the product was. (Does that mean they knew it's defective?)

Its replacement won't be from Crucial, but it will be bought from Amazon. If you want to give this drive a try in case I, and the various other people who've had problems with this drive are merely unlucky, I strongly suggest that you get it direct from Amazon too.
