ADATA's Ultimate SU800 is their first SSD to use 3 chiều NAND and the first 3 chiều NAND SSD from a company that doesn't manufacture their own NAND flash memory. The SU800 pairs Micron's 3 chiều TLC NAND with Silicon Motion's SM2258 controller khổng lồ produce an entry-level consumer SATA SSD, available in both 2.5" & M.2 size factors.

We've previously reviewed the Silicon Motion SM2258 controller in the hãng sản xuất intel SSD 540s, which uses SK Hynix 16nm TLC NAND. We also had the opportunity to test an SM2258 engineering sample/reference design from Silicon Motion that used the same Micron 3 chiều TLC but earlier firmware và different overprovisioning settings. Silicon Motion's controllers are known for low cost và low power, và it's worth noting that their SATA SSD controllers are one of the few remaining single-core designs.
Micron's 3d TLC is the first 3d NAND lớn hit the open market in high volume & with reasonable cost. For the moment, Micron's 3 chiều NAND is the only viable option for most SSD manufacturers looking lớn move beyond planar NAND. Samsung is keeping almost all of their 3d NAND for their own very successful SSDs. Toshiba và SK Hynix are technically shipping 3d NAND but in limited supply and the poor cost effectiveness have prevented any third parties from adopting it for commercial SSDs. Toshiba & SK Hynix each have at least one or two token models in the supply chain using their 3 chiều NAND, but still no mass-market consumer or retail availability. (Toshiba and SK Hynix have seen more success in the điện thoại cảm ứng thông minh and memory card markets, where performance requirements are lower and the large die sizes of Micron's 3d NAND are a problem.)
Micron's only consumer SSD with 3 chiều NAND so far is the Crucial MX300, và Intel has released their SSD 600p, both using the Intel/Micron 32-layer 384Gb 3 chiều TLC NAND flash. The Crucial MX300 has been quite successful, with acceptable mainstream performance, great pricing, & great power nguồn efficiency. The hãng intel 600p is the most affordable NVMe SSD on the market và it offers real-world performance that exceeds any SATA SSD. That leaves plenty of room in the market for other models with 3 chiều NAND, và plenty of interest from consumers seeking the benefits of 3 chiều NAND.

Micron's 32-layer 3d TLC NAND has a capacity of 384Gb (48GB) per die. This odd capacity means that while the SU800 has typical usable capacities lượt thích 128GB and 512GB, the die counts & raw flash capacities aren't powers of two. The 128GB SU800 has just three packages with one die each for a raw capacity of 144GiB. The 256GB & 512GB SU800s use three và six dual-die flash packages, respectively. Since the SM2258 controller has four channels for communicating with NAND, the smallest SU800 cannot make full use of the controller's capability and has reduced performance as a result. The larger capacity SU800 variants are rated lớn mostly saturate SATA on sequential transfers.
