The SSD resource is melting right before our eyes. Some Samsung 990 Pros have begun to wear out too  ...

Several owners of the Samsung 990 Pro SSD have complained about their SSDs failing too quickly. Despite the fact that the entire amount of overwritten information on the media was only a few terabytes, their condition indicator decreased by several percent, indicating the SSD's rapid wear.

After a short story about the rapid degradation of Samsung 990 Pro drives, much attention was devoted to the author of the Neowin portal, who himself discovered this issue. After only two days of using the device, the wear on the SSD was already 2%. After a couple of days, the drive's resource dropped to 94%.

All modern SSDs have support for SMART technology, which can read various media indicators. These statistics can then be displayed using dedicated monitoring applications such as CrystalDiskInfo. Samsung also has its own SSD monitoring application called Magician.

Just a few terabytes of overwritten data should not be considered as a significant decrease in media overwrite resource as is the case with the Neowin editor's drive. For the 1TB Samsung 990 Pro model, which claims 600 TBW, 1% wear is equivalent to overwriting 6 TB of information.

The Neowin editor encountered a similar situation on a 1TB Samsung 990 Pro, according to the ComputerBase portal at the end of December. In the second case, the 2 TB model lost 7% after overwriting 2 TB of information.

The same TBW for both drives is declared on the Reddit forum, where Samsung 990 Pro owners make their observations. For example, one user provided a visual comparison of the Samsung 990 Pro's wear rate using the Hard Disk Sentinel monitoring software.

The cause for the rapid wear of Samsung 990 Pro drives isn't clear at the moment. It's possible that a software bug is involved or that the monitoring applications are failing to recognize them correctly. If the issue is something else, then the rapid wear of these drives might indicate that the manufacturer's rewriting resource (TBW) is lower than it is. In this case, we would definitely need to replace the drive.

By the way, the Neowin editor contacted Samsung technical support, filled out the SSD return form, and even returned it to the owner for diagnostics, according to the report. Only after the story was published in the media, Samsung representatives wrote to the editor of Neowin, promising to replace his drive with a new one.
