ADATA Ultimate SU630 specifications: new SSD with QLC 3D memory up to 960 GB
The manufacturer of solid storage devices, ADATA, has just presented its new ADATA Ultimate SU630 SSD, in which it assembles the new memory type QLC, with a total of up to 960 GB of internal capacity. These new SSDs would be the perfect replacement for the hard drives of users who still use mechanical storage units on their desktop or laptop computers.
Little by little we are witnessing the arrival on the market of the first SSD equipped with the new QLC type memories, which are called to be part of the new batch of cheap SSD. This is so because the QLC technology itself allows up to 4 bits of data to be stored in each memory cell, which causes the storage capacity of each block to increase by 33% with respect to the current SSDs, which employ the TLC technology. All this means that you can make SSD with fewer NAND Flash memory chips, which lowers your final price.
The new ADATA Ultimate SU630 are SSD that use the traditional format of these, that is, they will be sold only in format of 2.5 inches, without the possibility of acquiring this model in M.2 format. Because of this, the units are a good replacement for users who wish to replace their mechanical units with these new solid units in devices with little internal space, such as laptops. In front of the mechanical units, the ADATA Ultimate SU630 SSDs will represent a good increase in performance.
Since these new ADATA SSDs will be limited, due to their form factor, to be able to use only the SATA bus of the motherboard, the transfer speeds are much lower than if they could use the PCIe bus. Even so, these are not bad at all, given that these SSD can reach up to 520 MB / s in reading, staying at 450 MB / s when it comes to writing data in blocks of NAND Flash memory. Even so, these speeds can vary between the three storage capacities that will be available: 240, 480 and 960 GB.
A part of the device’s QLC memory is used as if it were SLC memory, acting as a data cache, which greatly increases the performance of these new SSDs. Although, the really interesting thing about these ADATA Ultimate SU630 SSDs is the use of LDPC ECC technology (Low Density Parity Check Error Correction Code), which allows to detect and correct errors in the data when they are recorded in the memory cells, which increases the reliability and duration of the data stored inside it.
Also, with the purchase of a unit of these SSD Ultimate SU630, users can access the download of the ADATA SSD Toolbox, which is the software of the manufacturer, responsible for monitoring and reporting the performance of the SSD to users, including the information of the wear of the memory cells and the remaining life time for the unit. This tool also allows the migration of data from a storage device that we want to replace.
ADATA has not provided data on when this new model of SSD will begin to be commercialized, nor has it provided the price they will have when it reaches the market.
