0TS2510 Western Digital Ultrastar 61.44TB PCI E NVMe 4.0 Solid State Drive
0TS2510 Overview
The Western Digital Ultrastar DC SN655 61.44 TB SSD (model 0TS2510) is a high-capacity enterprise-grade NVMe solid-state drive designed for read-intensive data-center and server storage workloads. It uses a PCIe 4.0 ×4 NVMe 1.4 interface in a U.3 2.5-inch (15 mm) form factor, making it compatible with hot-swappable enterprise drive bays and high-density storage systems. The drive delivers strong performance with up to around 4,300 MB/s sequential read and 3,150 MB/s sequential write speeds, and up to about 890,000 IOPS random reads, providing fast access to large datasets in demanding applications. Read-intensive classification with 1 Drive Write Per Day (1 DWPD) endurance makes it suitable for workloads where data reads dominate.

HTS545050A7E380 Overview
With 7mm ultra-thin hard drives all the rage, Hitachi aims to blast one out of the park with its new 500GB single-platter Z5K500 – that’s right, 500GB on a single platter. Getting to this higher capacity in such a slim package has been a big deal for drive manufactures, since in the 7mm drive space you are limited to a single drive platter, instead of two in a 9.5mm drive or three in a 12.5mm drive. While capacity might be the biggest selling point of this drive, it is also important to see how well it does in the performance category.
