Final Thoughts


Micron's 3D flash has been on our radar for about a year now. Crucial's MX300 is the first end product to employ Micron's innovative 3D flash, and we are pleased with the results; especially when we take into consideration that the MX300 is a first-generation product. Crucial is marketing the MX300 as a mid-level performer and we believe that's exactly what it is. Our results show that the MX300 isn't a synthetic powerhouse, and that's fine by us, because it does deliver good performance where we believe it matters most; moderate workloads. We only need to look at our standard PCMark 8 testing to see that the MX300 is indeed more powerful than the vast majority of planar-based TLC SSDs.

When evaluating TLC-based SSDs, we really focus in on sustained write performance. In our opinion, every SSD should be able to, at the very least, deliver sustained write performance that matches or exceeds that of the fastest consumer-based spinning HDDs currently on the market. All SSDs do deliver a vastly superior end-user experience when utilized as an OS disk, due to much greater random performance than any spinning hard disk can deliver. However, tasks such as installing large games and transferring large amounts of data are common everyday tasks for most users. This is why we need to see a minimum of 200 MB/s sustained write performance from any SSD for it to even be considered for a TweakTown recommendation. At 374 MB/s of sustained write performance, or 3.6x that of the BX200, the MX300 easily meets our requirement for write performance.

At TweakTown, user experience while running the test subject as our OS disk is a big factor in determining whether or not it will receive a TweakTown recommendation. The user experience delivered by Crucial's MX300 is very good. Our system booted quickly, programs launched extremely fast, and the MX300 handled multi-tasking very well. Overall, Crucial's MX300 delivers an excellent SSD experience. With an MSRP of just 26.7 cents per gigabyte for 3D flash, we feel Crucial's MX300 750GB SATA III SSD is attractively priced at launch.

Crucial's MX300 750GB SSD is TweakTown recommended.
