16-year-old SSD surpasses 1 petabyte in data writes
A test conducted by an enthusiast shows the aging storage drive outlasted the manufacturer's endurance rating by 25 times.
An experiment conducted by a technology enthusiast has demonstrated the remarkable durability of an aging hardware component. A SanDisk P4 SSD model, released 16 years ago with the older SATA II interface, managed to record a petabyte of data through continuous writes.
The volume of information written to the solid-state drive was 25 times higher than the equipment's official endurance rating. This metric, known as TBW (Terabytes Written), indicates the amount of data the manufacturer guarantees the device can withstand before experiencing structural failures or loss of capacity.
The feat stands out because it involves technology considered obsolete by current market standards. Storage interfaces have evolved significantly since the tested model was released, but the experiment highlights that the write limit stipulated by manufacturers often serves as a conservative guarantee, far from the hardware's actual breaking point.
Although the drive surpassed the one-petabyte mark, the test did not detail the current state of corrupted sectors or the degradation of transfer speeds—common effects in processes of extreme flash memory wear. The result, however, provides empirical data on the longevity of solid-state storage drives subjected to massive workloads.
How much data did the 16-year-old SSD write in the test?
The 16-year-old SanDisk P4 SSD successfully recorded 1 petabyte of data through continuous writes during the experiment.
How does this compare to the manufacturer's endurance rating?
The 1 petabyte written is 25 times higher than the drive's official Terabytes Written (TBW) endurance rating, showing that manufacturer limits are highly conservative.
What is the TBW metric in solid-state drives?
TBW (Terabytes Written) indicates the amount of data a manufacturer guarantees an SSD can withstand before experiencing structural failures or loss of capacity.
