0R755K Dell 2TB 7200 RPM 3.5ft SAS HD - Server Storage

Our review of the 0R755K Dell 2TB 7200 RPM 3.5' SAS hard drive looks at who needs a reliable, original Dell hot-plug drive and why it remains a sensible upgrade for older PowerEdge servers. The bottom line: this is a straightforward, genuine replacement drive meant for administrators who need predictable capacity and compatibility with a range of Dell PE-series systems. It stands out for being an original Dell part with a tray included, making it easy to drop into compatible servers without adapter hassles.

Key Features

• Original Dell part: Ships as a genuine 0R755K unit so buyers get an OEM-quality replacement that fits Dell PowerEdge bays without modification.
• 2TB capacity: Provides a sizeable 2000GB of storage useful for bulk data, backups, or capacity expansion in server arrays.
• 7200 RPM performance: Delivers steady rotational speed suitable for general-purpose workloads and sequential I/O tasks.
• 3.5' SAS interface: Uses a 6Gb/s SAS connection for reliable enterprise-level link integrity and hot-plug support in supported chassis.
• Includes drive tray: Arrives ready to install in PE-series servers, removing the need to reuse or find a separate caddy.

Who It's For

This drive is best for IT teams and system administrators maintaining older Dell PowerEdge servers such as R310, R320, R410, R720 and compatible T and R series models listed with the part. It is a practical option for organizations that prefer OEM parts for predictable fit and supportability.

It is less suitable for users seeking NVMe-level performance, very high IOPS storage tiers, or the smallest physical footprint; those buyers should look at SSD or newer SAS/SATA options. Also, because this is a spinning media drive, it is not ideal where the absolute lowest latency is required.

Pros & Cons

Pros

• Genuine Dell part ensures proper fit and compatibility with many PowerEdge models.
• Good capacity at 2TB for archive, bulk storage, and capacity expansion tasks.
• Hot-plug ready with included tray for fast drive swaps and maintenance.
• 6Gb/s SAS interface offers robust connectivity for enterprise environments.

Cons

• 7200 RPM HDDs have lower IOPS and higher latency compared with modern SSDs, so not ideal for latency-sensitive databases.
