Review: Toshiba |
Despite how far SSDs have come, where even
the most basic SSD beats every hard disk on the market on performance, hard
disks do still currently have one significant advantage in that they are much more
affordable for storing data. In this review, we will take a look at Toshiba's
latest 1TB 2.5" 9.5mm HDD, which features two platters that spin at
5400RPM. Many competing 1TB 2.5” hard disks have a 12.5mm height to fit in 3
platters, making them too tall for laptop bays designed to take a 9.5mm hard
disk.
As a frequent use for large capacity HDDs
is for storage of bulky files such as photos and video, in this review we will
focus heavily on file handling performance, along with testing real world
performance using VirtualBox.
