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.

The range of scores (95th – 5th percentile) for the WD Blue 2.5″ 320GB (2009) is 27.9%. This is a relatively narrow range which indicates that the WD Blue 2.5″ 320GB (2009) performs reasonably consistently under varying real world conditions.

The Western Digital WD2500BHTZ is a high‑performance 250 GB internal hard disk drive from Western Digital’s legendary VelociRaptor family, engineered for users who need faster access and responsiveness than traditional 7200 RPM drives can provide. Unlike standard desktop HDDs, the VelociRaptor spins at a blistering 10 000 RPM and features a SATA III 6 Gb/s interface, allowing it to deliver sustained data throughput and quicker read/write access that benefits workstations, creative applications and performance‑oriented systems.
Whether installed in a desktop chassis or integrated into a high‑performance storage array, the delivers a notable combination of rotational speed, cache efficiency and sustained throughput that makes it a strong choice for applications where traditional HDDs fall short.
The 2TB X5 Portable SSD from Samsung is built with a 2TB NVMe SSD and a Thunderbolt 3 interface. Thanks to the combination of both technologies, this portable drive can deliver read and write speeds of up to 2800 MB/s and 2300 respectively. In addition to fast speeds, SSDs are built without any moving parts, making them more durable than their hard drive counterparts. For additional protection, it’s built with magnesium alloy to survive drops from up to 6′ high, as well as Dynamic Thermal Guard technology and a heatsink to keep things cool and prevent throttling. Physical security aside, the X5 also supports password protection via AES 256-bit encryption to keep your data safe. Please note that software updates for the X5 are only supported on Windows PCs
