Toshiba S300 4TB 3.5-inch SATA Surveillance Hard Drive, 5400 RPM, 256MB

Description

The Toshiba S300 4TB is a 3.5-inch internal hard drive for surveillance storage. This exact SKU is identified by HDWT840UZSVA and uses a SATA 6Gb/s interface.

It runs at 5400 RPM with 256MB of cache and SMR recording. The manufacturer lists a maximum sustained transfer rate of up to 184MB/s. SATA 6Gb/s is the interface bandwidth, not the sustained read or write speed of the disk.

The stated workload rating is 180TB/year, a measure of annual data activity rather than capacity. Toshiba specifies HDWT840UZSVA as the 4TB bulk S300 model. It is designed for surveillance recording, supports up to 64 cameras and up to eight drive bays, and uses SMR recording with a 5400 RPM spindle and 256MB buffer.

A SATA 6Gb/s host connection and a free 3.5-inch drive bay are required. Capacity, cache and RPM, together with recording technology, in this listing are tied to this exact model and are not copied from another capacity in the same series. For NAS, RAID or surveillance use, the host system should support the exact drive model and required SATA connection. The 3.5-inch format is intended for systems with a matching internal bay, SATA data connection and standard drive power connector.

    Returned items should be complete, securely packed, and returned with all original accessories and packaging where possible. Once the item is received, it will be inspected before any refund or replacement is approved.

    For CPUs and other delicate electronic components, we check for physical or installation-related damage, including bent pins, damaged contact pads, socket damage, thermal paste contamination, missing parts, or other signs of incorrect installation, misuse, or handling damage.

    If the item has been damaged after delivery or used beyond what is necessary to inspect it, this may affect refund eligibility, and a deduction or refusal may apply where permitted by law.
