CMS 1TB Mini m-SATA SSD Drive SATA III 6GB/s - High Capacity mSATA

In this review the CMS 1TB Mini m-SATA SSD is evaluated as a direct upgrade option for owners of supported Dell Precision mobile workstations. The bottom line is simple: it provides a full 1TB of solid-state capacity in a compact full-size mSATA form factor with SATA 3.0 throughput, making it a practical swap-in for systems requiring a high-capacity mSATA module. The drive's principal appeal is its balance of capacity and respectable sustained performance, especially in older Precision M3800, M4800 and M6800 systems that accept a single mini SATA socket.

Key Features

• 1TB Capacity: Offers a large single-drive storage upgrade suited for applications, large media libraries and project files without needing an external drive.
• Full-size mSATA Form Factor: Fits the mini SATA socket used in compatible mobile workstations for a straightforward internal replacement or upgrade.
• SATA III 6Gb/s Interface: Uses the SATA 3.0 interface to deliver up to 6 Gb/sec bandwidth where the host supports it, reducing transfer bottlenecks compared with older interfaces.
• Strong Read/Write Performance: Up to 550 MB/sec read and 470 MB/sec write performance provide noticeably faster boot, load and file-transfer times compared with traditional hard drives.
• MLC NAND Flash: Built with MLC NAND for durability and consistent performance in typical productivity and content-creation workloads.
• Limited Lifetime Warranty: Backed by a limited lifetime exchange or repair warranty from the manufacturer for defects, giving extra confidence at purchase.

Who It's For

This mSATA SSD is aimed at professionals and power users who own Dell Precision M3800, Precision Mobile Workstation M4800 or M6800 systems and need a high-capacity internal storage upgrade without replacing the laptop. It is also a good choice for users who prefer internal, single-unit storage over carrying external drives.

It is not for systems that lack an mSATA socket or for users who require NVMe performance; newer laptops with M.2 NVMe slots will see better speeds from NVMe drives. Those who need enterprise-level endurance ratings or specialized RAID configurations should consider other enterprise SSD lines instead.

Pros & Cons

Pros

• High 1TB capacity in a compact mSATA module ideal for large local storage needs.
• Solid SATA III sequential performance with up to 550 MB/sec read and 470 MB/sec write speeds.
• Uses MLC NAND and is manufactured by Computer Memory Solutions, avoiding generic sourcing concerns.

Cons

• Limited to SATA III interface speeds, so it will not match NVMe performance available in newer systems.
