<p>Solid state media data is saved to a pool of NAND flash. NAND itself is made up of what are called <a href="page.php?w=Floating-gate_transistors">floating gate transistors</a>. Unlike the transistor designs used in <a href="page.php?w=DRAM">DRAM</a>, which must be refreshed multiple times per second, NAND flash is designed to retain its charge state even when not powered up. The highest capacity drives commercially available are the <a href="page.php?w=Nimbus_Data">Nimbus Data</a> Exadrive© DC series drives, these drives come in capacities ranging</p><p>
