A breakthrough in innovation, the Crucial M550 SSD is over 20 times faster than a typical hard drive* and consumes significantly less power. It enables your computer to boot up almost immediately, load files and programs almost instantly, accelerate demanding applications, and manage power so that your battery lasts up to 50 minutes longer.
Every manufacturer has ideas about how to deliver better performance. Some use file compression schemes, but those don’t help video, audio, or graphic files that are already compressed. Some steal system memory to improve a slow drive. The Crucial M550 treats all files the same, regardless of whether they’re compressed or uncompressed, so the specs we advertise are the same ones you’ll see in real world use: true 550 MB/s sequential reads across all file types.
Our engineers are relentless and passionate about the products they create. To deliver consistently fast write performance, they developed a more efficient and dependable way to write data called Native Write Acceleration. This technology spreads the drive’s workload across several elements, and links the controller, custom firmware, and flash storage components together, enabling you to achieve inherently faster downloads, saves, and file transfers.
Run your system longer than ever before - and use less power. Based on published specs, a common laptop hard drive uses 2.5 watts of power on an average workload, compared to 0.15 watts on the Crucial M550 (which is up to 94% more energy efficient).
If one of your videos, photos, or files happened to get corrupted, there’s a good chance it would no longer be usable. That’s why we’ve taken additional safeguards to ensure the integrity of your data. As a leading manufacturer of the flash storage components that go into SSDs, our exclusive multi-step data integrity algorithm is built into the components we use, arming them with four layers of defense against data corruption.
You probably save lots of sensitive and personal information on your computer - encrypt it and keep it safe. As a self-encrypting drive, the Crucial M550 incorporates the highest level of hardware encryption into the controller, allowing the drive to operate at full speed without the performance loss associated with software-based encryption.
Push your drive to the limit and avoid overheating, even in ultra-small, thermally constrained systems. The Crucial M550 includes Adaptive Thermal Protection technology, which enables the drive to dynamically adjust NAND activity based on usage demands. With this technology, the drive is able to maintain optimal operating temperatures, even when you overwork it.
I am sorry for any issues you may be experiencing on your drive. Is your system crashing currently or are you only seeing the error on the drive?
Both traditional hard drives and SSDs will have a number of bad sectors as standard, however before a hard drive leaves the factory, the number of bad sectors is set to zero.
The industry standard for SSDs is different and the bad sectors count is not reset. This can make some SMART reporting tools believe the drive has a problem and is about to fail when in reality it is fine.
The best way to gauge an SSDs health is through its actual performance. If you are experiencing any crashing or performance issues with the SSD, please let us know and we can provide support on these.

I got a mSATA M4 here and "Power on hours" smart value won't update. I updated firmware, tried garbage collection and looked around but nothing..
What's weird is : while i let it run for hours in bios, after restart, these hours were counted. However in Windows nothing's counted. Changed power settings but no luck.
I've read that Crucial SSD had issues with haswell platworm (my laptop is one if them) so i plugged another non sata M4 SSD with its last firmware and it updates! I don't get it..
I would suggest checking for BIOS update and verifyng storage controller driver version. You can check the driver version with Device manager -> IDE ATA/ATAPI Controllers -> right click on the selected controller -> Properties -> Driver tab
Also I am not sure why your SMART screenshot has not been moderated yet but as for your SMART data it is not likely that all factors exceeded the thresholds. Please post text SMART data from CrystalDiskInfo ('Edit -> Copy' option) just please remove drive's serial number befor posting the data.
That is interesting. Few Mac users have been reporting similar issue but for other model, M500 as far as I can remember. How big are the files (data amount) you are trying to write at a time? Is the TRIM enabled on your system?
I was shocked today when I looked at my remaining available drive space.
At first I thought I had a partition problem when I saw I only had 307GB of capacity.
I normally expect some difference between raw capacity and reported capacity but this seems EXCESSIVE!!!!
Is this truly normal or do I have an issue?
