![]() ![]() The TBW, which stands for total bytes written, meaning the amount of data written on the drive before it begin to experience tearing problems. The bigger issue with TLC memory chips, compared to the two-bit MLC chips (and even more compared to the SLC memory chip, that store only one bit per cell) is the shorter lifespan, because there is more cell wearing on the erasing process (executed before writing new data). It allows a higher data density and, thus, a smaller manufacturing cost for a same capacity chip. This kind of memory stores not two, but three bits per cell. ![]() Just like most new SSDs, the A400 uses TLC (triple level cell) memories. Now we are including a new inexpensive SSD: the Kingston A400 120 GiB. Recently, we tested four 120 GiB new-generation entry SSDs: the WD Green, the Corsair Force LE, the Kingston SSDNow UV400, and the SanDisk SSD Plus, which are some of the most inexpensive SSDs available today. Let’s see how does it perform against its competitors. We tested another low-cost SSD, the Kingston A400 120 GiB. ![]()
