Capacity Capacity			500GB			240GB

Probably the best SATA III SSD you can buy for 60 US Dollar. Offered excellent performance (albeit it won't match any NVMe ones!) and suitable amount of capacity for that price. Overall a reliable all around SSD for nearly every computers unless if the computer has no support for SATA which means your computer is too old! ^{[Nov '19 ColdSpy]}

MORE DETAILS

Crucial’s BX300 SSD is a 3D MLC entry level SSD, with debut pricing in line with the Samsung's 850 Evo, the current market leader. The BX300 is one of the faster consumer SSDs available, with a 2% performance improvement over Crucial’s older MLC based MX200 and a 25% performance improvement over the TLC based MX300 which are both from Crucial’s more expensive MX product line. MLC NAND offers more consistent performance and has higher endurance than TLC NAND. Although Samsung’s 850 Evo (which is based on proprietary TLC V-NAND) has a 10% effective speed advantage over the BX300 the BX300 wins on write consistency. The 240GB BX300 has a three year warranty or 80 Terabytes Written (TBW) compared to five years or 75 (TBW) for the 250 GB 850 Evo. This makes for an interesting choice between the BX300 and the 850 Evo. Each model has an SLC cache which is proportional to its capacity, as a result the larger capacities offer better performance. The 120 GB BX300 has a 4 GB SLC cache, the 240 GB has 8 GB and the 480 GB has 16 GB. SLC caches improve burst write performance beyond the already respectable MLC write performance. Unfortunately, at least for now, the BX300 only comes in modest capacities, with the largest being 480 GB. For write consistency, thanks to its MLC NAND, the BX300 punches well above its price point. ^{[Nov '17 SSDrivePro]}
