SSD PCI-E

PCI-E card (HHHL)

— drives made in the form of expansion cards and plugged into PCI-E slots (just like external video cards, sound cards, etc.). The HHHL marking means half length and half height, so these modules are suitable not only for full-sized PCs, but also for more compact systems, such as nettops and even some laptops. The PCI-E interface allows you to achieve good data exchange speeds, moreover, it is through it that NVMe is implemented (see "Advanced"). On the other hand, these features are also available in more advanced and compact form factors, in particular M.2. Therefore, there are few SSD modules in the PCI-E card format on the market today.
