Western Digital 0TS2459

Overview

The Western Digital 0TS2459 is a 7.68TB UltraStar DC SN655 internal solid state drive designed for enterprise environments requiring high-speed storage and reliable data access. It uses a PCIe Gen4 interface with NVMe 1.4 protocol to deliver up to 6,800 MB/s sequential read speeds and supports a U.3 form factor for easy integration into modern server and storage systems. This drive is tailored for read-intensive workloads such as transaction-heavy databases, virtual machines, and real-time analytics where consistent performance and low latency are critical.

Key features

• High-capacity 7.68TB storage that accommodates large datasets and extensive log files.
• PCIe Gen4 interface with NVMe 1.4b support for fast data transfer and reduced bottlenecks.
• Dual-port design providing two independent PCIe paths to ensure continuous operation even if one path fails.
• End-to-end data path protection that verifies data integrity from host to NAND memory.
• Built-in power loss protection safeguards data in transit during unexpected shutdowns.
• Optimized for read-intensive enterprise workloads with steady throughput and low latency.
• Compatibility with Windows, Windows Server, and Linux operating systems without requiring additional drivers.
• Designed for deployment in dense server racks and all-flash arrays with a projected 2.5 million hour mean time between failures.

Connectivity and compatibility

This SSD fits into any server or storage shelf equipped with a U.3 interface, making it straightforward to deploy in existing infrastructure. It supports dual-port PCIe connections, which enhance reliability by providing redundant data paths. The drive is recognized natively by current versions of Windows, Windows Server, and Linux, eliminating the need for extra drivers and simplifying integration into diverse IT environments.

Performance and reliability

With a proprietary controller and Western Digital BiCS5 3D TLC NAND, the drive delivers high sequential and random read speeds that help eliminate storage bottlenecks in demanding applications. Its endurance rating supports frequent read operations and occasional batch writes, while power loss protection and end-to-end data path checks ensure data integrity. The dual-port design further enhances uptime by maintaining access through an alternate PCIe path if the primary one fails.

Ideal uses and environments

This SSD is well suited to data centers and enterprise setups that require fast, reliable storage for big data analytics, AI and machine learning workloads, content delivery networks, and hyperconverged infrastructure. It fits well in environments where steady throughput and consistent quality of service are essential, such as transaction-heavy databases and virtual machine hosting. Its robust design and high endurance make it a strong choice for continuous operation in dense server racks.

Orders are processed within 2 business days, which includes verification, packing, and dispatch. Shipping costs are calculated at checkout based on destination, total weight, and selected speed. Free shipping applies to carts over $100 (excluding heavyweight items). All available options and final pricing are clearly shown before payment so you can choose the service that best fits your needs.

Deliveries are handled by major carriers such as USPS, UPS, and FedEx. Estimated delivery times are displayed at checkout and may vary depending on service level and location. Please note that these are estimates and can be affected by weather, holidays, or carrier volume. Once your order ships, you’ll receive a tracking number for real-time updates from pickup to final delivery.

Providing an accurate shipping address helps prevent delays, and changes may be limited once the order has been dispatched. P.O. boxes are supported only when permitted by the selected carrier. Packaging and handoff are optimized to protect items during transit, though oversized or high-weight products may require special handling. All shipping methods and any related constraints are clearly shown during checkout.

Returns are accepted within 30 days of delivery. Items must be unused, in the same condition received, with tags, manuals, accessories, and original, unaltered packaging. Any item kept will be deducted from the refund. Start a return by sending us an email. Items sent back without approval may be refused or returned to the sender.

Some items are not returnable: opened TVs/combos/monitors 37″+, opened computers or software, electronic downloads, opened consumables (film, paper, bulbs, media, ink), custom or modified computers, special-order or “nonreturnable” items, submerged underwater gear, and opened educational media.

After inspection, refunds are issued to the original payment method; allow 5–7 business days for the credit to post. Shipping, handling, customs duties, and import taxes are nonrefundable. If an item is used, incomplete, or not in original condition, a 30% restocking fee may apply. Direct exchanges are not offered; purchase the replacement and return the original for a refund.

We act solely as a reseller. Any product warranty is provided and administered by the manufacturer, not by our store. That means eligibility, coverage, and outcomes are determined by the manufacturer’s policy for each brand and model. Before purchasing, we recommend reviewing the warranty terms on the manufacturer’s website or in the product documentation to confirm what is covered and for how long.

If you need warranty service, please file the claim directly with the manufacturer. They may require proof of purchase, the product serial number, original packaging, photos, or basic troubleshooting. Some brands ask you to register the product or obtain a case number before shipping it for repair or replacement. We don’t submit or approve claims, but we can point you to the correct support links and contact details.

Keep your invoice and packaging in a safe place, and report any functional issues to the manufacturer as soon as they appear. If you’re unsure whether a problem is covered, the manufacturer’s support team can confirm next steps and timelines. While we cannot intervene in decisions or outcomes, we’re happy to provide purchase documentation or guidance so you can move through the warranty process smoothly.
