Real-World Insights & Considerations

• Designed for Bulk Storage: Particularly excellent if you prioritize capacity and reliability over top-tier speed—perfect for media libraries, backups, and content archives .

• Write Performance Caveats: After the SLC cache (Turbo Write buffer) is exhausted, sustained write speeds can drop (e.g., from 500 MB/s to 100 MB/s)

• Performance vs HDD: While sequential and random IOPS performance trails NVME SSDs, it still massively outperforms traditional hard drives .

• Price-to-Value: Offers compelling value per gigabyte, though performance under sustained heavy write loads may lag due to QLC limitations .

• User Perspective (Reddit): As one user put it:

  “You’d probably want to buy these drives especially if you don’t have tons of writes, and if you have somewhat large amount of data…”
