Behind the brand Crucial is Micron, the company far from being a lightweight in the fiercely competitive SSD market, so you made some time ago with the Crucial C300, the first SATA 6Gb / s enabled before SSD and was primarily in the sequential transfer rate to travel to areas that were with the previous SATA 3Gb / s interface is simply not accessible . Meanwhile, many manufacturers have refills and 6 Gb / s are taken for granted, the Crucial m4, the closer we look at in this review, it has so easily this time not as the Crucial C300 in their time.
Micron is one of the few manufacturers that produced even flash memory, while also producing its own SSDs or sold, to this group also include Intel, Samsung and Toshiba, the latter two are more in the OEM and the retail market presence.
SSD manufacturers to buy all the components must be because they do not own production must be addressed when shopping for availability, this often leads to a model that are as different types of flash memory is used, this is usually straightforward, often arise but measurable although not significant differences in performance. This problem has obviously not because of Micron's production, the only component that needs to buy the Micron is the controller, this comes from Marvell, and in contrast to the SandForce controller is not supplied as a complete package that is, including firmware, this, however, more on the next page.
In the retail market with Micron Crucial brand is active, the Crucial SSD there is m4, in the OEM market, the drive under its own name as Micron C400 is sold, technically there is no difference between the drives, so it's legitimate to talk of the m4 and C400 alike.
