Thread: Crucial RealSSD C300

Back in June of this year we had the 128 GB version of the Crucial RealSSD C300 with SATA3 interface made in detail under the microscope. Meanwhile, the cheaper 64GB version found its way into our test lab and had the endurance to show what you put! As for the models with higher storage capacities, it is for the 64 GB RealSSD C300 is a solid state drive in the 2.5-inch enclosure, equipped with a 128 MB comprehensive reading and writing buffer. Crucial as controller relies on technology from Marvell, flanked by the company Micron Flash devices.



Crucial is a Marvell controller for connecting the flash memory cells to a SATA3 interface with 6 Gbps. In particular, these are at the 88SS9174-BJP2, which also comes in models with 128 GB and 256 GB used. The controller are a total of eight channels for communication with the built-in NAND flash cells. The 16 memory chips (eight on each PCB side) come from chip giant Micron (0JB12 NW273) and are delivered in MLC technology. Another Micron IC provides 128 MB of DDR cache memory. TRIM is also part of the repertoire of RealSSD C300.

The TRIM command allows an operating system of the SSD to announce that deleted or otherwise vacant units no longer in use. Normally, the operating system noted in the administrative structures of the file system that the corresponding areas are available again for new data; the controller of the Solid State Drive receives this information, but not in the rule. By the ATA TRIM command is communicated to the drive when you delete files that the affected blocks as invalid, rather than hold their data further. The contents are no longer co-written, so that the write access speed to the drive and also the effects of wear can be reduced.
