HGST Ultrastar SSD1600MM HUSMM1640ASS200 400 GB Internal SSD

In this review the HGST Ultrastar SSD1600MM HUSMM1640ASS200 400 GB internal solid state drive is evaluated as a straightforward upgrade option for servers and storage systems that need consistent, durable flash storage. The bottom line: this is a no-frills, brand new 2.5in SSD aimed at enterprise or prosumer setups that require a 400 GB capacity and proven OEM model numbers like P/N 0B31066 and P0002847-001. The review focuses on build intent, compatibility cues, and expected reliability rather than consumer-focused extras.

Key Features

• 400 GB Capacity: Provides a mid-range capacity suitable for system volumes, caching, or dense virtual machine images without overspending on larger SSDs.
• 2.5in Form Factor: Fits standard 2.5in bays in servers, workstations, and enclosures for easy installation and replacement.
• Enterprise Model IDs: Uses factory model identifiers such as HUSMM1640ASS200 and P/N 0B31066 which aid in exact replacements and inventory matching.
• Brand New Condition: Arrives new from the manufacturer packaging, reducing the risk of prior wear that can be a concern with used enterprise drives.
• OEM Part Reference: The P0002847-001 reference helps when confirming firmware and compatibility with blade or rack systems that expect OEM parts.

Who It's For

This drive will appeal to IT administrators, system builders, and prosumers who need a dependable 400 GB 2.5in SSD for server caching, boot volumes, or compact storage arrays. Those replacing a specific HGST industrial drive or matching fleet inventory will appreciate the exact part identifiers listed in the product details.

It is less suitable for casual desktop users who want consumer features like bundled cloning software, flashy retail packaging, or mainstream retail warranties; likewise, buyers seeking the fastest NVMe consumer performance or large-capacity consumer drives should look elsewhere.

Pros & Cons

Pros
