Solid state drives in the usual format of a laptop disk have been around for eight years, the range of offers with SATA interface is wide and varied both in terms of volume and in terms of price accessibility. But here’s the bandwidth of SATA exhausted, and more and more SSD is released in the form factor M.2. One of these innovations is the A-Data SX8200NP, based on a fresh controller from Silicon Motion. Let’s look at it in action.
On the eye to distinguish one SSD form factor 2280 from the other is only on the marking and the number of chips on the textual. In our case, there are seven of them – a controller, two “buffers” of DDR3 and four NAND-memory chips. A controller of the new medium-budget, Silicon Motion SM2262. It was introduced last year, supports NVMe version 1.3 and is designed to work on the PCI Express x4 interface. Maximum sequential read and write speeds are 3.5 and 3 GB / s, respectively. User data is stored in four chips with a three-dimensional TLC-memory manufactured by Micron, a “useful” volume of 894 GB. To the drive is attached a small heatsink made of a 0.3 mm aluminum plate, decorated with the manufacturer’s logo.
All ADATA drives are managed by the SSD Toolbox, a small utility with a user-friendly interface. Two of her goals are: informing about SSD parameters and conducting the simplest maintenance operations: disk condition test, data deletion, firmware upgrade. The utility reports about 22 ° C on the controller, while in the room the air warmed up to 28 degrees. Earlier similar jambs at work with disks ADATA did not arise. Apparently, you need to make adjustments to the algorithms of interaction with new drives.
Looking at CrystalDiskMark results, it becomes clear where the data on the speeds of sequential reading and writing in the specifications on the site come from – 3181 and 1757 MB / s, respectively. No less impressive are the random reading/writing parameters: 2599 and 1728 MB / s. AS SSD produces much more modest: sequential read / write 2277/800 MB / s.
Indications CrystalDiskMark and AS SSD
The closest to reality picture shows the charts in AIDA: the average values for sequential access do not exceed 2458/825 MB / sec, random – 829/595 MB / sec. Despite the significant difference from the declared parameters, for an inexpensive SSD, the figures are decent.
The disc is definitely bright. But full sale can show only sales of this device.
