At the end of August Crucial introduced the third generation of its BX-SSDs. The new BX300 is available with storage capacities of 120, 240 and 480 gigabytes and is designed to eliminate the biggest weakness of its predecessor, the slow write rate. We will clarify whether this succeeds in our test.
According to Crucial, the BX300 should write with about 520 MByte/s and read with 560 MByte/s. Crucial no longer uses cheap TLC flash, but instead relies on high-quality MLC memory. The controller used is a Silicon Motion SM2258 with four memory channels, which accesses eight NAND chips.
The SSD also comes with a mounting spacer so that this thin SSD can also be used in laptops without the SSD flying back and forth. You also get a license for Acronis True Image HD.
