A device twice as big should be able to handle twice as much data in its life. You can see that the warrantied life is proportionate to size: 600TBW per terabyte of device storage, which makes sense.

Most SSD manufacturers specify how many bytes can be written to the drive within the device’s guarantee.įor example, the machine I’m using has two SSDs. The more you write to them, the more SSDs wear out. The drive may last longer or fail earlier, but this lets you judge your risk against the manufacturer’s expectations based on your current usage.

You can then use a tool to examine the amount of data written to your drive to determine how close to the TBW it is. The specifications for an SSD model may include a TBW, or “terabytes written” measure of the minimum life expectancy.
