Samsung has led the way, now moves to Crucial and upgraded to. The decisive innovation in the Crucial CT250MX200SSD1 250GB (6.4 cm (2.5 inches) 7mm, SATA III) variant is the so-called Dynamic Write Acceleration. This is a second level cache, which Samsung has already since the introduction of EVO series in use. MLC memory is written only partially, only one bit and so to speak, used as a pseudo SLC memory.
Thus, the memory cells are filled directly, but only when the electronics has decided that they should be described. Thereby, the memory cells are protected and also the overall performance increases. If Samsung is available for this technique only a certain range of SSD. Crucial are theoretically all the memory cells can be used as a pseudo cache. According to Crucial Dynamic Cache is limited to half of the drive capacity and the memory should be adapted dynamically.
The durability of the new series is the 250GB variant at 80 TB over 3 years, equivalent to 73 GB per day. The EVO 840 is about the half. As memory cells are 16-nm MLC Micron used as a controller of Marvell 88SS9189 (8 NAND Channel).
The technical data at a glance:

* As a mean time to failure of 1.5 million hours are indicated.
In principle, the power was increased by 4 to 10% compared to its predecessor. Whether the extra cost for the new technology is worthwhile, everyone must decide for themselves. Especially good at Crucial is the life indeed. I had already bought several disks of different series, is never a failure. The firmware updates always run at Crucial without problems, which can not be said of all manufacturers.
In particular, the hardware-based BitLocker Drive Encryption in conjunction with a TPM module (Trusted Platform Module) is useful. It no longer comes to extreme slowdowns or show wear the SSD. The modules are available for current, standard motherboards in stores and can be plugged directly onto the motherboard in the corresponding well. Subsequently, the module must be activated and set in the BIOS and in Windows. On the Microsoft homepage all essential steps are well explained. If you want any additional passwords, can tie the module to the Microsoft account, so that the Windows password the BitLocker password and the PC is automatically activated immediately with the Windows Start and unique password input at the same time. For your own safety, you can save the password to a file or make a printout. A USB flash drive, you can set as a key, but should not be lost. Better 2-3x secure, otherwise the PC can no longer be used and the hard drive is locked forever. However, the drive encryption leads to loss of speed that are subjectively imperceptible, however. The read values are almost the same, only when writing halved performance because the data must be encrypted so. From the BitLocker support I am very impressed. In times of NSA, Trojans, spam, hackers and cybercriminals should maximally protect the domestic data from external intrusions.
The equipment is rounded off with Acronis True Image HD software. This allows you to transfer the old drive to the new SSD. However, Acronis is not as reliable in our experience. If you have problems with Acronis, should pick up the freeware tool 'DriveClone 11' of FARSTONE. This software is provided by various journals on the download page for free. Thus, it works without problems. To convert a cable is also required, which is not included.

In a Sony VAIO SVE 15.5 inch notebook with Intel Core i3 3110m processor with 2.4GHz, 6GB RAM, AMD HD 7650M (1GB) graphics chip, DVD, Windows 8.1 achieved the Crucial MX200 has a score of 1029 'a very good value for a notebook built in December 2012. The values specified by the manufacturer, however, can only be achieved in a desktop PC or a notebook latest design. Power consumption is especially gratifying. According CPUID HWMonitor this is even below the 840 EVO series, which is very economical. Thus, the SSD is also suitable for laptops. The fan in the Sony VAIO jumps to rarely, what constitutes a standard hard drive or SSD older design was absolutely impossible. The fan then ran permanently. Who the latest technology is not as important, has no actual hardware in use and also something you want to save, may also draw to its predecessor without hesitation, if it is still available. For the new series will probably replace the old soon.

These two 2.5-inch versions come out even without second level cache, as they fully utilize the SATA interface.
