For an experiment, the host of the YouTube channel “Good Choice!” decided to buy several cheap SSDs: DEXP C100 (128 GB, 1050 rubles), Netac SA500 (120 GB, 1290 rubles), Digma Run Y2 (128 GB, 1067 rubles), HikVision C100 (120 GB, 1190 rubles), Kingspec ( 120 GB, 1090 rubles). All of these models were exposed to 1400 hours of stress load.
After 1420 hours on the HikVision C100, 580 TB of data was written and just over 13 TB of data was read. He was running out of resources (he only had 10% left).
At the same time, everything worked fine with Digma Run Y2 in the CrystalDiskInfo program. I managed to burn a 171 TB SSD. But it also needed to be reformatted.
The DEXP C100 recorded 415 TB, while the Netac SA500 recorded 303 TB. Their remaining resources were 32% and 47% respectively. The internal structures of these SSDs are the same at first glance.
Kingspec was able to record 326TB and had 100% resources.
As for the reading speed, in all cases the indicators turned out to be close to those at the beginning of the test.
I chose this instead of advertising.
If we talk about the recording speed, for the DEXP C100 it ranged from 67 to 164 Mb/s (linear recording). Steady drops of up to 1 Mb/s were noticed during random recording.
A similar situation exists with the Netac SA500. But it turns out that linear registration is more uniform than random registration. In a random save, the first 30 GB are recorded more or less normally, and then there is a distribution with drops.
Digma Run Y2 froze while trying to record linearly. But in the random registration test, everything was fine, even without strong drawbacks. However, it had the slowest overall speed throughout the entire test – 171 TB payload.
Kingspec also froze after 10GB of linear recording. In a random recording, the average speed of this SSD was 220 MB / s and there were no problems.
HikVision C100 recorded the most data during the entire test: almost 600 TB. At the same time, their schedule was also smooth. The linear reading dropped slightly as the drive filled, but the speed was still reasonable. With Random it was the opposite: it had the best speeds – with drops of 50% in the second half of the test.
