Tape has always been denser geometrically than HDDs. More surface area on a reel vs a platter. SSDs would be the opposite of tape. Big$/GB low latency vs. Low$

SSDs would be the opposite of tape. Big$/GB low latency vs. Low$/GB high latency. Obviously SSDs would replace almost all other media if it could beat tape on $/GB.
- stephengillie 14y agoWhen you consider the $/GB, do you consider the cost of operating these as mechanical devices - mechanical wear and fatigue, increased electricity usage, administrative costs (tape storage, space for robot to work, robot repairs, etc), and possibility of damage (dropped tapes)?
- johngalt 14y agoYes of course those are considered and the results may surprise you. One of the beautiful things about tapes is that you can store them unpowered. All you power is the robot(s) and the drive(s). 100 tapes sitting idle in a silo will last much longer than 100 hard drives spinning at 7200rpm. SSD's failure rates are even higher than HDDs.
