👎 Cons
- The 3.5-inch form factor may not be suitable for smaller server enclosures or systems that require 2.5-inch drives.
- The advanced technologies like ePMR, CMR, OptiNAND, EAMR, and TSA, while beneficial, are highly technical and may not be fully understood or utilized by general consumers.
- The high capacity and enterprise-grade features likely come with a premium price point, which may be a barrier for non-enterprise users.
- While the 2.5M hours MTBF is a strong indicator of reliability, it is a "projected" figure, not an absolute guarantee for every single drive.
- The drive is designed for enterprise applications, meaning it might have characteristics (e.g., noise levels, specific firmware) that are less ideal for personal desktop use compared to consumer-grade drives.
