Crucial BX300: Cheap SSD at high speed

Tuesday, August 29th, 2017 | Gadgets

The BX series is traditionally the SSD series at Crucial, which should convince mainly by its low price. The new BX300 models follow the BX200 family of last year and are equipped with modern technology. This allows Crucial to significantly increase the speed of the SSDs, which is important for the extremely slow BX200.

Instead of planar flash memory with three bits per cell (Triple Level Cell, TLC) the manufacturer uses 3D-NAND with layered cells, each storing two bits (Multilevel Cell, MLC). The flash memory comes from the parent company Micron, specifically it is this with 256 GB capacity. They are controlled by Silicon Motions SM2258 controller, a low-cost chip with four flash channels and Sata-6-Gbit / s interface. The BX300 is available with 120 GB, with 240 GB as well as with 480 GB and only in 2.5 inch construction with 7 mm height. A 1 TB model like the BX100 or BX200 is missing.

Crucial uses a pseudo-SLC buffer of 4 over 8 to 16 GB depending on the capacity. The SSDs achieve their full write speed of up to 510 MB per second. If the cache is full, however, the performance drops only slightly due to the fast MLC FLASH memory. Reading, the SSD creates up to 555 MByte the second. Measured values ​​from Anandtech and computer base show that the BX300 can compete with Samsung's 850 Evo.

However, it lacks a hardware encryption and the warranty is three instead of five years. The BX300 is too expensive to travel with lists of 61 to 91 to 153 euros. If the SSDs in the coming weeks but as expected is still somewhat cheaper, they are a recommendation.
