Serious capacity issues may exist with Samsung 990 Pro SSDs

Some customers have reported serious issues with the health of one of Samsung’s flagship SSDs, which might severely impair the device’s performance.

Available in 1TB and 2TB capacities and sporting sequential read/write speeds of up to 7,450 / 6,900 MB/s and a price tag of roughly $170/£160 and $290/£280, respectively, the PCIe 4.0 990 Pro SSD is a major upgrade over the 980 model it replaces.

In addition, it has Samsung’s Magician software at its disposal, which may be used for performance optimization, data security, firmware upgrades, and drive health monitoring.

SSD Samsung 990 Pro issue

For Samsung, that piece of software has caused more problems than it has solved. Many 990 Pro owners have reported sudden health declines, even when they haven’t come close to filling their drives.

After utilising Magician and other tools for a few days, Robbie Khan of Neowin reported a 1% decrease in the health of his 990 Pro. Khan also operates other Samsung drives with enormous quantities of data saved on them, and he reports still seeing 99% health after a year and a half, so he knew this wasn’t typical.

The percentage decreased to 98% after another day or so, and by that time I hadn’t even written 2TB on the disc. A few more days passed, and the drive was at 95% health, he added.

After Khan’s 990 Pro plummeted to 94%, he sent it in to be fixed. However, he was then informed that “there was no problem identified,” and his original hard drive was returned to him after being reformatted.

Other Internet users, such as those on Reddit (opens in new tab) and Twitter (opens in new tab), have since complained about their own 990 Pro SSDs.

Following this, Samsung Germany released a statement saying:

“Samsung guarantees the high standard of all of its SSDs, including the brand-new NVMe M.2 SSD 990 PRO. Since there is a wide variety of user setups, we are aware of complaints of this problem and are looking into it.
