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've got an M550 SATA that fails to be recognized in the laptop's BIOS (no boot, etc). The same thing happened about 4 months ago, when i just bought the combo. I had to format it in another computer and afterwards it started being detected again (lost all the data) on the E7440. At the time i tried the reinitialization procedure in vain.
Is there a known issue between these 2 pieces of hardware?
As the title states, it cannot be done.
It is clear from the "Introduction" part of the instructions (and in practical terms) that the update process is supposed to be done only from the firmware 02 or 03 to 05, but not from the 01... Is there a way to do so, I mean, update from MU01 to MU05?
Maybe it is just a matter of a two steps process, like from 01 to 02 or 02 then to 05, but I cannt seem to find but only the latest firmware.
Thanks in advance
Windows 7 would have to be SP1 and if you have Intel chipset drivers installed, make sure they are up to date: https://downloadcenter.intel.com/SearchResult.aspx?lang=eng&keyword=%22Intel+Rapid+Storage+Technology+%28Intel+RST%29%22
Otherwise you won't support advanced format (4k sector) drives.
I bought new Crucial MX100 256GB for my laptop.
Theoretical transfers should be about 550MB/s.... ok thats is thery.... but my SSD has 200MB/s MAX.
Disk was tested without any partition in my deskop PC as additional drive.
Desktop PC Config: GA-P67A-UD4-B3 (rev. 1.1) + i5 2500k + 8GB DDR1866 + WIn7
then I put this disk to destination laptop (toshiba p75a7200 with i7 4700MQ and I recovered win 8.1
the results was even worse
Please tell me why?
To weak configs ?
I've seen a couple of other cases where people have mentioned this.
By the way, there is a forum rule that we don't mention other drives or SSD makers by name. In any case, for those not familiar with the history behind these tests, there is a well known SSD using TLC NAND, where prior to the latest firmware release, the read speeds when reading old data appeared to be significantly degraded.
in some cases the read speeds for this SSD were reported to be slower than 100 MB/s and it was claimed that the difference could be seen with data that had been written only one month prior to the read speed tests.
The read speeds for freshly written data was still good with these drives and since most benchmark software writes a file and immediately reads it back again, most people were unable to measure the drop in performance. Now people are checking other drives to see if the same problem occurs in other makes and models of SSD.
Since I don't have Windows I can't run HD Tune with my M500 240GB SSD, but I do have some older files on my macbook pro and I can tell from the directory timestamp, that these files were written 6 months ago or earlier.
Using the dd command in the Mac terminal:
$ dd if=misc/centos/CentOS-6.5-x86_64-minimal.iso of=/dev/null bs=256k 1592+0 records in 1592+0 records out 417333248 bytes transferred in 0.962690 secs (433507465 bytes/sec)
The read speed for this file appears to be better than 400 MB/s.
The test using the dd command would not be valid if the file has had been cached in RAM, so would only be valid for files not read since boot time. I've checked some other files and got similar speeds. Perhaps I should reboot and test again.
This file was written in 2013.
$ dd if=misc/apple/osx/10.8.4/InstallESD.dmg of=/dev/null bs=256k 16927+1 records in 16927+1 records out 4437341116 bytes transferred in 10.484844 secs (423214788 bytes/sec)
Once again, the read speed is better than 400MB/s, so I'm not seeing any problem here.
I'm running Firmware MU05 on the M500.
$ smartctl -i disk0 | egrep 'Model|Firmware' Model Family: Crucial/Micron RealSSD C300/M500 Device Model: Crucial_CT240M500SSD1 Firmware Version: MU05
Hopefully others can test their Crucial SSD and we can get some indication about how common this problem is.
