We really have to look at the SX900 two ways. The first comes from the enthusiast in me who would be pissed off about buying an SX900 last year and just now getting TRIM support. Along the same line, the SX900 has at least three different builds, so unless you bought all of your drives for RAID at the exact same time, your chances of getting matched pairs for RAID are like trying to win big at a carnival game. You are not going home with the giant stuffed bear for your girlfriend! ADATA still advertises the SX900 as "The most powerful SSD on Earth", so enthusiasts must still be on their radar. The advertisement shows an SX900 in space and that's about the only place where that claim can be made - someone's head is way above the clouds.
Back on solid ground, the SX900 is a strong competitor for the mainstream crown. It delivers solid performance at a good price point. SX900 is not a Samsung 840 Pro or OCZ Vector, but it doesn't cost as much either. Keeping with the mainstream theme, it delivers better battery life than either of the two drives mentioned above and it doesn't have that absolutely awful latency found on the Samsung 840 120GB.
The battery life is the real standout feature on the new SX900, but it's not like you can buy an SX900 and even know what you are getting. There are three major components to an SSD - firmware, controller and flash, and the drive we reviewed today only shares the firmware with the unknown other SX900 configurations that have shipped. We know of two others making it three... that we know of! We asked before how many Ford parts you can fit on a Ferrari and it still be called a Ferrari. Well, if battery life is your concern then how many Ferrari parts can you fit on a Ford?
We would love to be able to point to some type of indication that says the drive you want has the new B02/20nm parts, but there isn't one. Hopefully ADATA will take this mini rant to heart and revise some type of product numbering scheme - hello VERSION 2, SX901, SX900.5, or something!
The sad thing is somewhere inside ADATA an engineer was smart enough to build a really good SSD, but once the project was passed on, the significance of the part was hidden behind a marketing budget. ADATA thought the new 7mm z-height was a big enough improvement to release a press statement, but the increased battery life wasn't. I bet you can guess what the new SX900 7mm's product name is.
