drive use wet tantalum capacitors in its design?
No. For reliability reasons, the E-Disk® drive uses only solid tantalum capacitors. A solid tantalum capacitor is an electrolytic capacitor in which the anode is a porous pellet of tantalum. The dielectric is an extremely thin layer of tantalum pentoxide (Ta2O5) formed by anodization of the exterior and interior surfaces of the pellet. The cathode is a layer of the semiconductor manganese dioxide (MnO2) that fills the pores of the anode over the dielectric. Solid tantalum capacitors, well known for their high levels of reliability and stability, are used where high reliability and long service life are important. They are used in critical, long life reliability applications such as aerospace, hardware and medical implantable hardware and are also extensively used in electronic circuits for filtering and by-pass applications. A wet tantalum capacitor is a capacitor with a liquid acid electrolyte in the can, which is the equivalent of manganese dioxide (MnO2) in solid tantalum capacitors
