The Ultimate SU750 comes in an eye-catching, black and blue box. Along with a picture of the drive, the front advertises many of its key features including its 512GB capacity, SATA 6Gbps interface and 3D NAND. The back of the box provides a bit more information regarding the SU750's features and performance. Surprisingly, the SU750 does not come with any accessories or documentation. I'm guessing this is an attempt by ADATA to make the drive as affordable as possible.
Physical Features:
The Ultimate SU750 looks very similar to ADATA's other 2.5-inch SSDs. The top of the outer casing is made out of black plastic with a large, blue and black sticker showing that the SSD is part of the company's SU750 series. The bottom of the casing is made out of metal and is painted black to match the top. The sticker on the bottom shows information like the model number, warranty code and WWN code.
The Ultimate SU750 is one of the first drives to use Realtek's new RTS5733DMQ controller. There isn't a lot of information available regarding this controller but after talking to Realtek we learned that it supports two channels with up to eight chip enables (CE) per channel. The RTS5733DMQ is also compatible with 3D TLC/QLC NAND flash and offers features like AES 256-bit encryption and low-density parity check (LDPC) technology for greater reliability. For whatever reason though, AES encryption does not appear to be enabled on the SU750.
For the 512GB version of the SU750, ADATA has opted to use its own 3D TLC NAND flash. Looking at the picture above, you can see that there are two 256GB NAND flash packages on bottom of the PCB. Also take note that there is no DRAM cache chip. According to Realtek, the DRAM cache is embedded in the RTS5733DMQ.
