Is QLC SSD worth buying? It is believed that many of you are wondering about this question. As a matter of fact, this is depending on the brand's warranty and price of the brand QLC SSD. Here, this post will discuss this question in 3 points and you should be sensible to buy this SSD.
According to the current data released by flash memory manufacturers, it is not a problem that QLC solid-state drive (SSD) can be used for three to five years. And you don't have to worry too much about the drop problem of speed. It will definitely drop, but it won't affect your use.
But if there was a QLC SSD, perhaps you would hesitate to buy it. Well then, is QLC SSD worth buying? Let's see three points.
QLC and TLC are two types of flash memory. But as for QLC vs TLC, what are the differences and which one is better? This post answers to you.
1. Overcome Anxiety of QLC
HDD is easy to hang and has many bad sectors although you use the HDD very carefully. Besides, the computer using HDD starts up very slowly. Therefore, SSD is a good choice for data storage.
However, SSD is expensive although some SSDs can cost $1 each 1GB. Especially for users who have a need of large SSD, it's still too expensive to use as a storage disk and there aren't any solid state drives with too much capacity.
Then, QLC SSD seems to be the only option since its capacity can reach TB and the speed seems to be fast. So is QLC SSD worth buying?
Firstly, you need to overcome the anxiety of this SSD - the lifespan. Micron and Toshiba both say their 3D QLC flash memory can be erased for 1000PE. This is basically the same as TLC. Thus, if you're using TLC right now, you can use QLC with an easy mind.
2. 3D NAND Increases the Life of QLC SSD
The reason for the high erasure life of QLC is 3D NAND. It can be said that without 3D NAND, QLC may appear after several years. In fact, TLC was accepted by the enterprise because of 3D NAND to a great extent.
With the help of 3D NAND, QLC can achieve the lifetime of 1000PE. At present, all manufacturers that have announced the launch of QLC also use 3D NAND.
Here, we won't calculate in detail how long the QLC SSD of 1000PE can be used. For common users, it is not a problem to use the SSD for more than 5 years and this is why Intel's QLC SSD product offers a five-year warranty. Currently, QLC will be used in the enterprise first, so ordinary users should not worry about the lifespan.
3. Don't Worry about the Speed of QLC SSD
The data offered by many manufacturers is slightly different. Intel's 660P supports NVMe with sequential read and write speed up to 1800MB/s and 1100MB/s. The sequential read and write speed of Samsung SATA SSD can be up to 540MB/s and 520MB/s. According to the official data, QLC solid state drives can work well in speed.
But some of you may worry about the speed of SSD will drop. Even so, random read and write performance will be better than HDD's. As a system disk, the startup speed is still fast.

After knowing so much information, as to the question "is QLC SSD worth buying", we want to say: please be sensible. And the main thing is to see how long the brand's warranty lasts and whether the price is cheap enough.
