Crucial has learned a lot from their previous BX Series SSDs and have applied that knowledge and experience toward making the BX300 one of the best price to performance values on the market today. The BX300 is indeed targeted at first-time SSD upgraders. As such, the BX300 is only offered in three capacities - 120, 240 and 480GB. This makes sense for a value line of SSDs because 240GB is overall the best-selling capacity point and new adopters aren't usually willing to shell out a lot of money for an SSD experience. So, what can you expect when you upgrade your spinning rust bucket to a Crucial BX300? Your computer will boot in seconds, apps load almost instantly and files save faster. Crucial says the BX300 will give you about 300% better performance than a traditional mechanical HDD. The BX300 runs cooler, quieter (silent) and consumes far less power than an HDD. Lower power consumption means longer battery life for laptop users. Crucial claims the BX300 is 90% more power efficient than an HDD. Additionally, SSDs are far more reliable than mechanical storage media. SSDs are superior to HDDs on all fronts. Once you have an SSD experience, you will never want to go back.
