The Samsung 870 QVO 8TB is a clear example of the value of QLC memory in reducing cost per gigabyte in general consumption SSD drives, a sector where the degree of demand in terms of reliability, resistance to writing cycles and useful life is less marked if we make a direct comparison with the professional sector.
Amazon has listed the Samsung 870 QVO 8 TB with a price of $ 899.99, a pretty good figure, since it translates into an approximate cost of 11 cents per gigabyte. It is true that we are still moving at a level far from traditional hard drives, since today we can find 8 TB HDD drives at 7,200 RPM with an average price between 200 and 250 dollars (from just over 200 euros in Spain), but we must also remember that between an HDD and an SSD there is a world of difference in terms of performance, and also in terms of latencies and access times.
To shape the Samsung 870 QVO 8 TB, the South Korean giant has used QLC (quad level cell) memory stacked in 3D (V-NAND), a type of memory that allows you to store four bits per cell, and that is a step forward compared to TLC memory (three bits per cell) in terms of costs, although in return they offer less resistance to writing cycles and have a shorter useful life. All in all, it shouldn’t be a problem considering it’s targeting the general consumer market, a level where most users do read operations.
We know that the Samsung 870 QVO 8TB uses the 2.5 inch format and SATA III interface. They have not transcended their read and write speeds, but we can assume that they will be in the range of 540 and 520 MB / s (sequential reading and writing).
What type of user is the Samsung 870 QVO 8TB intended for?
It is a good question, and the truth is that we can consider it as a “niche” product, since being a high-capacity model based on QLC memory, the ideal is to try reduce the write cycles and the size of these. Obviously, this contrasts with its own nature, since it is a high-capacity unit and therefore serves to store files and heavy content.
It could give its best in the hands of users who want keep your favorite games installed for long periods of time, for example, and also to those who use applications and heavy contents that benefit from the greater performance and the shorter access times that an SSD drive offers.
The difference between an HDD and an SSD, although the latter is SATA III and not PCIE, it’s abysmal, do not forget. I understand that with the rise of the latter and with the announcement of PS5 and Xbox Series X, SATA III-based drives have been losing interest, but are still perfectly viable for mounting high-performance equipment at an affordable price.
