What is TBW SSD?
What is TBW SSD?
Another metric used for SSD write endurance is Terabytes Written (TBW), which describes how much data can be written to the SSD over the life of the drive.
What is a good TBW for SSD?
A typical TBW figure for a 250 GB SSD lies between 60 and 150 terabytes written. A normal office user writes approximately between 10 and 35 GB on a normal day. Even if one raises this amount up to 40 GB, it means that they could write (and only write) more than almost 5 years until they reach the 70 TBW limit.
Is SSD TBW important?
This is why TBW is important, because it indicates how many times you could re-write an SSD drive before it can no longer hold on to your data. It is a different way to indicate the lifetime of the device.
Does TBW matter SSD?
But when it comes to storage, that’s more important than you might think. That’s where Total Bytes Written, or TBW, becomes crucial. However, it’s not so with storage. When a hard drive or SSD fails, if you don’t have a backup in place, you can lose priceless data.
What is the life of SSD drives?
Current estimates put the age limit for SSDs around 10 years, though the average SSD lifespan is shorter. In fact, a joint study between Google and the University of Toronto tested SSDs over a multi-year period. During that study, they found the age of an SSD was the primary determinant of when it stopped working.
What happens when you reach SSD TBW?
When it does reach that, your warranty will be void (if it’s not already due to the age). Most likely nothing will go wrong with the SSD for a long time after; SSD manufacturers tend to greatly underestimate the write capacity of their drives. Eventually, the drive will show down, then stop working all together.
How do you know if SSD is TBW?
Spec sheets often provide TBW cumulatively, which you’ll need to divide by its lifetime. For example, if your drive has a warranty period of 5 years, then 4 TB × 365 days/year × 5 years = 7,300 TBW = 7.3 PBW total.
How long will a 600 TBW SSD last?
A TBW of 600 with a usage rate of 9.25TB/year (half of the 18.5 I used in two years) would indicate 64 years of life left. Well beyond the calendar warranty of five years, and certainly longer than my machine — and I — are likely to be around.
How do I increase the lifespan of my SSD?
Contrary to popular belief, solid-state drives can benefit from occasional defragmentation — there is such a thing as too much fragmentation — but it does not have to occur on a regular basis. Disabling the system’s pagefile or moving the pagefile to a different drive can also extend SSD lifespan.
What does TBW stand for in reference to a SSD?
TBW stands for Terabytes Written. It can also be referred to as “endurance”. It is a metric indicated by hardware manufactures to state how many terabytes could be written to the solid state disk (SSD) during it’s lifetime.
What is the best internal solid state drive?

What is the life expectancy of a SSD drive?
The life expectancy of a SSD drive is said to extend to 50 years, which is pretty hard to believe and most likely not applicable to servers. It must be somewhat close. Unfortunately, SSDs as we know it have been around only for a couple of years, so no one really knows.
How many write cycles SSD?
An SSD that stores a single data bit per cell, known as single-level cell (SLC) NAND flash, can typically support up to 100,000 write cycles. An SSD that stores two bits of data per cell, commonly referred to as multi-level cell (MLC) flash, generally sustains up to 10,000 write cycles with planar NAND and up to 35,000 write cycles with 3D NAND.
