CMS 512GB mSATA Internal SSD Compatible with Dell M6800 - Fast 6Gb/s

In this review the CMS 512GB mSATA Internal SSD is evaluated as a straightforward upgrade for users who need a reliable, high-capacity internal drive for a Dell Precision Mobile Workstation M6800. The bottom line: this is a practical replacement drive that delivers the key advantages of SATA 3.0 throughput and solid-state responsiveness without unnecessary extras. It is best for technicians and workstation owners seeking a direct-fit 512GB mSATA module to restore capacity and improve sustained transfer speeds compared with older mechanical drives.

Key Features

• 512GB Capacity: Provides ample space for large project files, virtual machines, or a primary OS and applications on a mobile workstation.
• Full-size mSATA Form Factor: Fits the mSATA slot in compatible systems such as the Dell Precision M6800 for an easy, internal upgrade.
• SATA 3.0 6Gb/s Interface: Ensures compatibility with modern SATA controllers and supports higher transfer ceilings than SATA II.
• Performance Read/Write: Up to 550 MB/sec read and 470 MB/sec write for quicker boot times and noticeably faster file operations than typical HDDs.
• MLC NAND Flash: Uses multi-level cell NAND for a balance of endurance and cost, appropriate for workstation workloads.
• Compact Dimensions: The 50 x 30 x 3.5mm module is small and unobtrusive, making installation simple in cramped internal bays.

Who It's For

This module is aimed at owners of the Dell Precision Mobile Workstation M6800 and similar systems that accept a full-size mSATA module. It is a good choice for professionals who run CAD, content creation suites, or large data sets where faster read/write speeds improve responsiveness.

Users who need extreme write endurance for heavy constant write workloads or those looking for NVMe-level speeds should look elsewhere; this SATA 3.0 mSATA drive is not an NVMe device and therefore does not reach PCIe transfer rates.

Pros & Cons

Pros

• Direct compatibility with the Dell Precision M6800 makes replacement or upgrade straightforward.
• High sequential read and write numbers (up to 550/470 MB/sec) noticeably speed OS and app tasks versus HDDs.
• 512GB capacity gives ample room for programs, projects, and scratch space without relying on external storage.
• Compact, industry-standard mSATA size simplifies installation into internal slots.

Cons

• Being a SATA 3.0 mSATA drive, it is inherently slower than contemporary NVMe SSDs and will not deliver PCIe-level throughput.
• MLC flash is a solid compromise but may not match the endurance of specialized enterprise SLC or newer TLC variants designed for heavy write cycles.

Frequently Asked Questions

Will this drive fit my Dell Precision M6800?
Yes, the drive is specified as compatible with the Dell Precision Mobile Workstation M6800 and uses the full-size mSATA form factor required by that model.

Is this an NVMe SSD?
No, this module uses a SATA 3.0 interface at 6Gb/sec and is not NVMe; performance is limited to SATA bandwidth.

What kind of NAND does it use and what does that mean?
The SSD uses MLC NAND flash, which balances durability and cost and is suitable for typical workstation workloads though not the highest-end write-intensive enterprise tasks.
