We purchased one of these drives to compare to the Samsung 840 and 850 drives we use in the majority of our laptops and workstations. From a speed perspective, there are no concerns. The Crucial drive more than holds its own against the EVO-series drives. Samsung's 850 Pro drives are faster, but cost twice as much.
Overall performance consistency is reasonably good as well. If the drive is nearly filled there are noticeable stalls until TRIM completes. Underprovisioning the drive by 20% solved this issue (see below).
The MX100 claims to have TCG Opal 2.0 support for hardware encryption. This is flaky at best. The first drive we had did allow encryption using a passphrase, but lost its configuration after three weeks. This led to a bricked drive - no available partitions. Crucial does not offer a utility to reset the PSID - essentially wiping the drive clean. This is a problem with other Crucial SSDs, but hdparm could reset those back to factory default conditions.
The MX100 is reported as not being Opal 2 compliant by hdparm, so the drive could not be reset. Crucial sent a replacement MX100 with newer firmware, which did not allow setting a drive password at all. Not only did hdparm in Linux complain about lacking Opal 2 support, but so did Bitlocker and Symantec Endpoint Encryption under Windows.
If having hardware-encrypted data is a requirement for your use, the MX100 is not a good choice. Crucial's tech support claimed this should be fixed in a firmware upgrade, but 7 months after launch no revised firmware is available.
We opted to stick with Samsung SSDs - the EVO series for most work, the Pro series for high performance needs. The $30 price premium buys a more compatible drive with full support for firmware upgrades and optimization utilities.
Having a SSD where, depending on the firmware revision, encryption either needs to be done through software (with the associated performance hit) or is unreliable and can brick the drive isn't worth the lower cost.
If encryption is not a requirement for you, the MX100 offers excellent speed. To keep performance consistent, however, we found the drive needed to be underprovisioned. When installing the operating system simply make a partition having 80% of the drive capacity. This gives enough free space for Crucial's garbage collection algorithms to maintain performance without causing noticeable hangs and slowing.
Very fast, so fast that the Windows 7 logo doesn't have time to finish animating on bootup.
It died after three months. PC goes through a POST loop with the SSD plugged in. Going to file a warranty claim.
This is my third SSD, but my first Crucial. I've used Crucial memory products many times in the past and always considered them a top brand. This SSD experience is disappointing.
