The ADATA Ultimate SU630 is one of the first consumer SSD drives on the market with 3D V-NAND QLC memory, available in 240, 480 and 960 GB versions. I would not rule out the possibility of more capacious options in the future: after all, QLC memory allows this due to increased write density. QLC (Quad-Level Cell) is a new type of MLC (Multi — level Cell) memory, in which 4 bits of information are written to a single cell. 64-layer 3D QLC flash memory chips are used.
What is included?
ADATA Ultimate SU630 comes in a simple blister with a plastic transparent outer part. You can see the drive itself from the front, and all the basic technical information is printed on a cardboard backing.
What does ADATA Ultimate SU630 look like?
There is not much to tell about the appearance of any 2.5-inch SSD drive. They are standard in size and design and usually differ only in the colors of the case and stickers. Before us-a typical modern SSD 2.5 format with a black metal case 7 mm thick. It is very light: only 47.5 g. on the Front there is a black and green sticker with the ADATA logo and the model name.
As ADATA Ultimate SU630 shows itself in the work?
In TLC-memory-eight levels of charge in cells, in the new QLC-sixteen, respectively, the density of writing information is higher and the price for 1 GB decreases. But, at the same time, the speed of work decreases due to technological features when writing and reading information. QLC is the optimal solution for high-volume entry-level budget models. Another compromise in this case is guaranteed data write volumes (TBW) – 100 TB for the 480 GB model, the manufacturer gives a 2-year warranty. The competition these figures are higher. TBW 960 GB model claimed 200 TB, while the nearest competitor, Samsung SSD 860 QVO on 1 TB, this figure is 360 TB.
Now let’s go to the technical characteristics of the ADATA Ultimate SU630 tested on 480 GB. It uses 64-layer QLC 3D V-NAND memory, a 14-nanometer dual-core Maxio MAS0902A-B2C controller without DRAM memory. SLC caching is used to increase the speed of operation. The manufacturer promises a maximum reading speed of 520 MB/s and writing speed of 450 MB / s. The speed of working with 4K blocks promises 65,000 IOPS when writing and 40,000 IOPS when reading.
Now let’s remember about SLC caching. The maximum speed of the drive is shown until the SLC cache is full. A test of linear writing in AIDA64 showed that at first the speed is kept at about 490 MB/s. But after writing about 30 GB (this is our SLC cache), the speed drops sharply and fluctuates around 50 MB/s with periodic subsidence up to 30 MB / s and short-term jumps to the maximum speed (attempts to clear the cache).
What you can do with proprietary software?
To work with the drive, ADATA has provided a proprietary utility SSD ToolBox. It looks pretty “clumsy”, but all the necessary functions are available. There are status diagnostics, TRIM settings, S. M. A. R. T. information, firmware updates, and an overheat notification function.
ADATA Ultimate SU630 demonstrates the claimed performance that corresponds to typical entry-level SSD drives. It is perfect for not too expensive transition to SSD from hard drives. The main and, perhaps, the most correct sphere of application will be home PCs and laptops with a scenario of use, in which it is assumed to write once and read information repeatedly. How interesting the drive is will be clear when mass market entry.
