Windrose Early Access Game Reportedly Damages SSDs

The early access release of the pirate survival adventure Windrose has drawn significant scrutiny after players discovered the game was generating excessive disk I/O workloads that could potentially shorten the lifespan of solid-state drives (SSDs).

Developed by Kraken Express and released on Steam on April 14, 2026, the game quickly became a commercial success, selling over 1.5 million copies in just over two weeks. However, the title soon made headlines for its storage behavior, which some users reported was quietly killing their hardware through abnormal write cycles.

Technical Cause of Excessive Disk Writes

The issue stemmed from the way the game handled player progression data. Kraken Express utilized the RocksDB database system, but the implementation was misconfigured. Specifically, the game ran three separate RocksDB databases with a very small cache budget.

Because the cache was quickly exhausted, the system was forced to perform frequent, direct write operations to the disk. This resulted in a massive amount of data being written during standard gameplay, particularly when players were moving through the world.

Technical analysis revealed that the game could write approximately 108 GB of data per hour. In a typical four-hour gaming session, this could result in 432 GB of data being written to the drive. Disk usage frequently spiked to 30 MB/s when a player’s character roamed around a base, and the workload intensified further when piloting a ship.

The scale of the resource consumption was highlighted by YouTuber Pixel Operative, who compared the storage workload of Windrose against other survival titles. In a test spanning 60 to 90 seconds, Windrose read 32 GB and wrote 1.3 GB to the drive. During the same interval, Enshrouded read 7 GB and wrote 695 MB, while Valheim read 1 GB and wrote 5 MB.

Impact on Hardware Lifespan

The primary concern for users was the wear on NAND flash memory. SSDs have a finite number of write cycles, often measured as Total Bytes Written (TBW). While modern TLC (Triple-Level Cell) SSDs are generally robust enough to handle such workloads without immediate failure, other drive types are more vulnerable.

Reports indicated that QLC (Quad-Level Cell) drives and older, already worn-out SSDs faced a higher risk of degradation due to the sustained I/O pressure. Some users on Steam forums also reported that the constant writing caused their drives to overheat, with one user noting a system drive temperature of 83°C during play.

Developer Response and Patch Resolution

Kraken Express responded to the reports by deploying a housekeeping update on April 30, 2026. Patch version 0.10.0.4 specifically addressed the SSD and CPU usage issues, along with various connectivity bugs and missing building assets.

The patch significantly altered the database performance. Pre-patch testing showed RocksDB generating between 90,000 and 130,000 writes per second. Following the update, average writes during sailing dropped to between 20 and 30 writes per second, with peaks remaining below 60 writes per second.

According to findings from Pixel Operative, the update resulted in a 60% to 75% improvement in disk usage. Post-patch write speeds were measured between 10 MB/s and 16 MB/s, dropping below 1 MB/s when the player character remained stationary.

Additional Fixes and Future Roadmap

Beyond the storage fixes, the April 30 update introduced several quality-of-life improvements, including:

• A new Force Relay Connection setting to improve networking stability by bypassing the standard P2P loop and using Kraken Express relay servers.
• The addition of over 40 missing wall triangle pieces and three floor triangle pieces to improve building consistency.
• A reduction in the crafting costs for a wide range of building pieces.
• Fixes for high CPU usage on idle servers and clients.

Kraken Express has stated that the studio is now focusing on stability to prepare for future expansions. The developer confirmed that the first major content drop will feature the Ashlands, a new biome described as being covered in volcanic ash and occupied by undead. The studio noted that the Ashlands will take at least six months to deliver.
