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.
SMART data seems to look healthy in my opinion. I think I would try to check for BIOS update and also I would verify versions (and probably try to update them) of Intel Chipset Drivers and Intel Management Engine - either from Asus or from Intel site.
You can try to use Intel Driver Update Utility for that - sometimes it works
I know there are threads about this topic already. But I want that Crucial is aware of this issue. I builded a new PC on friday the 5th September. Until yesterday, the PC was working fine. But yesterday I was playing a game and for the first time with my new PC I got an Bluescreen and Windows shutted down. Then after a restart I became the message that there are no bootable drives available. In Bios my SSD was not shown.
So I turned off the PC and restarted it and still no SSD in Bios. Then another reset and there it was again and booted normally. Then I played about 4 hours without any problems.
Today I started my PC and immediately get the message that there is no bootable drive availabe. PC shutdown and turned it on again. Yet no SSD in Bios. Then I did a warmstart and there the SSD was back again. And since then I am using the PC normally again.
AHCI in Bios is on and the SSD is set to first boot drive. I also changed the SATA and even the power cable with a new one. And still got the problem.
ASRock H97Pro4 (newest Bios FW)
Windows 8.1 (brand new fresh installation)
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.
two years ago, I bought Crucial M4 128GB SSD and it was very fast. For last 6 months I have a problem with very slow write speed even for big files. The write speed starts at 200 MB/s but after few seconds it starts to going down to 30-35 MB/s and keeps there for rest of writing. Read is OK.
I use Macbook Pro early 2011 and tried both the newest firmware and the original 0309 with similar result. The amount of free space is there average about 30 GB. Now about 70 GB and still the same.
I also tried to let the ssd connected for few hours without booting system to activate garbage collector as I read here from some guru, it helps for few hours but then this issue came back.
Do you have any idea how to solve it? Thank you so much!
I have my Windows 7 installed on the following drive: M4-CT256M4SSD1
Recently Windows and a range of different programs have been freezing quite often, along with an occational blue screen of death.
The first time I noticed anything was wrong was while taking a backup of the entire drive to an external disk with EASEUS Todo Backup. It resulted in a BSOD in the middle of the backup process, and when restarting the computer the SSD had been deprioritized in the BIOS boot-sequence.
I've run SFC /SCANNOW, which tells me there are corrupt files in the Windows installation.
The CHKDSK also tells me there are errors/bad sectors that can't be fixed.
I've also kept track of the S.M.A.R.T.-stats of the M4 SDD, that have developed somewhat over the last days.

Especially the BB-field (Reported Uncorrectable Errors) has increased considerably from thursday to monday -- from 140466 to 166293.
It seems there might be something wrong with the disk, and that reinstalling Windows might not fix the issue?
