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.
Hi, New to SSD. I installed Win7 64 bit on MX100. When it rebooted for the first time, it said hardware not compatible. I ended up setting the RAID function to ACHI and was able to install OS and get the SSD working. However with ACHI mode instead of RAID, I cannot use the existing RAID array in my computer. How do I get both of them to play nice together? I have an Asus Rampage Extreme LGA 775 Intel X48 motherboard. Was I supposed to add the RAID driver in during Win7 installation? I remember doing that years ago... I hope this is enough info to get some help. Thanks for reading! If I do need to add the RAID driver, during Win 7 installation, will that setup a NEW RAID? As in wiping out the existing data?
I got a brand new MX100, just did a couple of OS installs. While checking the SMART data, I noticed the D2 value of 2D000000000000. I couldn't find attributes for MX100, but in M500 it's Successful RAIN Recovery Count. Is this value normal? I'd think it should be zero for a new disk.

Don't even bother to use you "supposed 3 year warranty", I tried to do so with a faulty V4 64Gb and Crucial tried to scam me:
[Edited per Guidelines: Be relevant.]
I'm having the exact same issue on a HP Pavilion G6 notebook. Warm boot OK, but cold boot (removed battery and unplugged power to clear charge) the drive goes missing.
The machine worked fine with original HDD, another HDD I imaged to as a test, and two different other SSDs (one Sandforce and one Silicon Motion based).
I just bought an 512gb crucial mx100 for my macbook pro as a second ssd a few weeks before. It's a late 2011 macbook pro 17" - the drive sits in the optical bay. Since I have not used the drive much I have not noticed it till today but when I am trying to play a video on it the drive just stalls every 5-20 minutes for like 10-20 seconds, then it continues like nothing happened.
First I thought it was a bad video file, but it happens with each file. I also have to add, that when I first installed the drive and moved cca. 100gb of data back to it, it was not going entirely smooth, as it also stopped during write operation, after like 30-40gb, and stayed in a halted state for like 20-30 secs, then went on like nothing happened - I did not think it was a bug, just thought some caches filled, etc therefore the wait.
But now I looked after this bug since it seems more severe, and itt looks like lots of people are having the same problem, I/O operations stop for no apparent reason.
I use this drive as a second drive, my boot OS drive is a s---ung 840 240gb drive. I've previously used a 750 gb normal hdd next to it, it had no problems whatsoever - so the sata connection inside the laptop is 100%.
This is not my first SSD, it's the third, I have no problems like this with any of the other drives.
Let me write what I've tried so far:
- I have tried turning of TRIM (trim enabler was running) - no changes even if it's on or off, does not matter
- I have turned on in system prefs that the ssd always has power (so it could do garbage collection) - nothing changed
- I tried installing the latest OSX update, 10.9.5 - system rebooted, same symptoms.
- I do not have any acronis app installed. Never did, never will. Only use the built-in time machine for backup.
I do not have any windows machines only macs, so don't tell me I should try it in a windows machine with xx intel driver, or change some things in the bios (macs do not have a pc like bios) - I cannot do any of that.
I also will not try swapping the drives, so do not write to me that I should get the crucial drive out of the optiocal bay and put it to the normal hd place - it is exactly the same, would be a waste of time anyway.
I do not think that "power cycling" or how you say would solve it, it is a brand new drive, barely used, having it sitting idle for 2 x 30 minutes makes no sense to me at all.
I also noticed that by checking the copying of data to/from it, that when it reads, it reads at around 250-260 mb/sec (should be around 500-550), when the drive writes, it writes as it should around 500-550 mb/sec. The read operation usually stalls after around 0.5gb-6 gb, then it stays that way for 10-20 secs, and then goes on. Write operation seems a bit better, it seems to stall less often, I could write bigger files, I'd say it stops after 5-12 gb is written, then waits a bit and continues.
SMART data seems OK, 200-300 gb of data was written to it max so far. It all seems like a firmware or driver issue, however macs do not have drivers in such abundance as on windows (it's all more controlled), also there is no firmware upgrade whatsoever for this drive yet.
If any of you guys have something to add to this, please go on. I have read through the forums now quite a bit, there does not seems a satisfying solution to this - except on windows, where some driver changing solves it, also uninstalling acronis seems to be a solution for windows guys.
So far it's a big dissatisfaction.
