Most hard disk drives (HDD) last between three and five years before some component fails. That doesnât always mean the drive is irrecoverably busted, but three to five years is still about how long they last, whether youâre talking about an internal drive for a server or desktop, or an external hard disk drive.
Of course the answer is, it depends. Smaller signal tubes, such as the 6DJ8 are rated to last about 5,000 hours and the more durable versions will last incrementally longer. An output tube is typically thought to last 2,000 hours, but then you are talking about using them to drive speakers. When used in a headphone amp, such as the EL-34 in the ASL MG Head, the demands will not be so great, as when driving speakers, so they should last longer.
