ADATA SX300 128GB mSATA SSD Review



Even though I wasn't able to fully stretch the legs of the ADATA SX300 128GB mSATA SSD since my mSATA port is only SATA2, I still feel like the visible performance is very comforting. Most likely, this drive will be used in a laptop or other small form factor device, where either a SATA3 mSATA port will be unlikely or the raw performance from SATA3 is just not necessary and won't typically be missed.

The closest "apples to apples" comparisons I was able to see came from the small file read/write tests where the drive's bandwidth isn't capped by the SATA2 interface. In these tests, we find the ADATA SX300 mSATA SSD to be matching up quite well with the other top competitors. The SandForce controller is certainly an excellent medium for excellent drive performance, even if limited by a SATA2 port on a SATA3 drive. Moving to an SSD on a laptop, in particular, creates a much better experience with must faster startup and shutdown times and improved battery life. With an ADATA SSD in my laptop, it can shut down and restart in the time that it can hibernate and boot up. For just under $1 per gigabyte, the ADATA SX300 provides very nice enhancements over a conventional mechanical hard drive. Even though I'm using it on a SATA2 interface and I know I am missing out on some raw performance, to the naked eye, day-to-day tasks would not show much difference.



  • Cost-effective upgrade to conventional HDD in mobile machines
  • mSATA interface allows user to retain HDD as a storage drive
  • Less than $1/GB for mSATA SATA3



  • None
