0TS2468 Western Digital 7.68TB PCI E NVMe Ruby Solid State Drive
0TS2468 Overview
The Western Digital Ultrastar DC SN655 7.68 TB is an enterprise‑grade NVMe solid‑state drive designed for demanding data‑center and server workloads where large capacity and consistent performance are critical. It uses a PCIe 4.0 ×4 NVMe 1.4 interface in a U.3 2.5‑inch (15 mm) form factor, providing broad compatibility with hot‑swappable enterprise drive bays. The drive is built with TLC 3D NAND flash and offers strong sequential performance with up to about 6,800 MB/s read and 2,600 MB/s write speeds, along with high random I/O performance — roughly 980,000 IOPS for random reads and 80,000 IOPS for random writes — helping accelerate access to large datasets in read‑heavy environments.

WD5000BPVT Overview
Quiet – In a notebook drive, silence is golden. WD’s exclusive WhisperDrive™ combines state-of-the-art seeking algorithms to yield one of the quietest 2.5-inch hard drives on the market. These algorithms also optimize the way a drive seeks for data, which significantly improves power consumption. So now silence (and longer battery life) is golden.
Reliable and Rugged – WD’s ShockGuard™ technology protects the drive mechanics and platter surfaces from shocks. WD’s SecurePark ™ parks the recording heads off the disk surface during spin up, spin down and when the drive is off. This ensures the recording head never touches the disk surface resulting in improved long term reliability due to less head wear, and improved non-operational shock tolerance.
