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.
As the title suggests, I only see 476 GB in windows. I know traditional drives can have a difference due to bad blocks, but SSDs from other companies have (more a less) given me almost 'as advertised' disk space. Is this normal or did I get a dud?
I did everything correctly. I Initialized my ssd,formatted,cloned the old HD to my ssd and i was able to boot from my ssd using a external adapter. Then i replaced the old hd to the ssd. when i turned on, a flashing folder icon with a question mark was on my screen. triend to restart and hold "option" key , but the macbook didn't find my ssd.
This problems seems to get worse over time and I feel like nothing I do is helping. Before when I had this problem it was when my computer had an unplanned sudden power off which I understand effects most SSDs for not able to read for awhile. Now ever time I even do a restart or normal shut down when my computer turns back on the m4 SSD is not found and takes 40 minutes up to 3 hours to be found again. Does anyone have any suggestions? I am concered my SSD is getting close to the end.
I am sorry for the issues that you are experiencing with updating the firmware on your SSD. What is the make and model of the system that the SSD is installed in?
For PCs, both laptop and desktop, please try these steps:
•Verify that the system has the ability to boot from a USB drive
•Ensure boot order in BIOS is set to boot from USB drive first
•Disable any BIOS and HDD passwords
•Recreate the bootable USB drive, in case something went wrong
•Try the process with a different USB flash drive
If you are still experiencing issues, please give us a call or email us directly and we would be happy to look into the issue further. I am sorry for the inconvenience.
According the description of the lasted firmware 070H http://www.crucial.com/usa/en/support-ssd-firmware the power timing issue on M4 should be definitively solved.
Resolved a power-up timing issue that could result in a drive hang, resulting in an inability to communicate with the host computer. The hang condition would typically occur during power-up or resume from Sleep or Hibernate. Most often, a new power cycle will clear the condition and allow normal operations to continue. The failure mode has only been observed in factory test. The failure mode is believed to have been contained to the factory. This fix is being implemented for all new builds, for all form factors, as a precautionary measure. The fix may be implemented in the field, as desired, to prevent occurrence of this boot-time failure. To date, no known field returns have been shown to be related to this issue. A failure of this type would typically be recoverable by a system reset.
I run a M4 256 since one year with the lasted firmware and I just faced the same issue. I have to run this process to recover my SSD http://forum.crucial.com/t5/Crucial-SSDs/Why-did-my-SSD-quot-disappear-quot-from-my-system/ta-p/65215
Should I ask for a replacement ?
