Will my SSD wear out or lose performance the longer I use it?
我的 SSD 固態硬碟是否會隨著使用時數的增長而有所耗損或發生效能減損？
The NAND Flash used in USB, SD cards and SSDs all have endurance limits meaning one cannot continue to write to them forever. Flash based products will eventually wear out however with features like wear-levelling and over-provisioning an SSD will typically last longer than the system it was installed into. We measure drive endurance in TBW (Terabytes Written) and depending on drive capacity one can write hundreds of terabytes, up to petabytes. Performance of the SSD will remain the same throughout the life of the drive. Learn more about TBW.
• 使用在 USB、SD 卡和 SSD 固態硬碟當中的 NAND 快閃記憶體都有其耐用性極限，一旦超過後就再也無法繼續寫入。儘管快閃記憶體型式的產品終究會有損耗，但搭配如平均抹寫和超容量快取等技術，SSD 固態硬碟一般的壽命都能夠超過其所安裝的系統。我們以「寫入兆位元組」(TeraBytes Written，TBW) 來測量硬碟耐用性，而依據硬碟容量的不同，可寫入的資料量可達數百 TB 至 PB。在整個硬碟的生命週期內，SSD 固態硬碟的效能都能維持相同。深入瞭解 TBW。
