480GB is the highest capacity of BX300 SSD. It’s also the fastest version as you can see in the table above.
Below are screenshots from diagnostic software. Crucial Storage Executive provides about everything you may need with heath status and additional options to update firmware or enable additional caching to boost performance.
Above window is showing SMART status. As you can see, our SSD is in perfect condition. Below is also screenshot from CrystalDiskInfo, one of the most popular applications which is showing info about the storage devices.
In the package we will find 2.5-inch 7mm SSD with SATA connector, 7mm to 9.5mm spacer, Acronis HD migration software key and installation manual. Most users wont need the manual while cloning software is always good addition.
Package is typical for Crucial SSD. It’s a small, flat box which is enough to protect the SSD. Package is simple but includes all we need to know about the product inside. On the other hand most users will purchase the SSD via online stores so package won’t matter much.
Also the SSD isn’t much different to what we are used to see. Last BX/MX series SSD were looking similar. Front label looks about the same for last 2-3 years if not longer. Also simple but looks good so there is no reason to change it.
Reviewed Crucial BX300 SSD is 7mm thick what means it will work with all new laptops and ultrabooks where is space for 2.5″ drive and also with attached spacer it’s possible to install it in older laptops.
Under the hood we will find Micron 256Gbit 32-layer 3D MLC NAND and Silicon Motion SM2258 controller. Write endurance is expected at about 160TB what is about the same result as for older, Crucial MX200 MLC SSD. At the same time is lower than the MX300. The MX300 also provides hardware encryption which isn’t available in BX300. Here are the most important differences while performance wise, both SSD shouldn’t be far from each other.
On the PCB there is also 16GB SLC cache and 512MB of DDR3 DRAM. Crucial is Micron brand so all memory chips are made by Micron. I guess it’s logical. Micron provides top quality computer memory for years so it’s clearly an advantage. Many competitive brands are using cheaper chips to balance costs what sometimes affect performance or endurance of the SSD.
This is our first SSD on the new Silicon Motion controller. Let’s move to the next page to check how it is performing.
