typically for read-intensive and boot/logging applications. TCG OPAL 2.0
support means interoperability with leading industry security ISVs applications.
For products built around high capacities and thin form factors
From ultrathin consumer notebooks to corporate platforms, the X400 SSDs
range of form factors and capacities deliver a variety of design and integration
options for manufacturers and systems builders. With a 1.5mm single-sided
form factor (M.2 2280 module), X400 SSD’s performance and capacities
make it ideal for ultrathin designs. Additionally, the X400 SSD is available in
2.5”/7mm-height as a true drop in replacement for mechanical HDDs. Both
form factors are available in 128GB, 256GB, 512GB and 1TB1 capacities.
