In the table below, we compared the tested units.
This value is usually very high and will not be a problem for typical home usage, but it makes these models inadvisable for applications that need a big amount of data writing, like servers, for example. The main 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 smaller lifespan, because there is more cell wearing on the erasing process (executed before writing new data), which reflects in a smaller TBW (Total Bytes Written, which means the amount of data that can be written to the drive before it can have problems). It allows a higher data density and, thus, a smaller manufacturing cost for a same capacity chip. This kind of memory stores not two, as on most MLC memory chips, but three bits instead. Because of this, now we tested the 240 GiB model from the same line, which is the most recent entry-level SSD family from Western Digital.Īs most of the recent entry SSDs, the WD Green uses TLC (triple level cell) memories. Recently, we tested the 120 GiB WD Green, but we know SSDs from different capacities, even from the same model, have different performances.
Let’s see how it performs, comparing it to other SSDs with the same capacity. This time we tested one more value SSD, the WD Green 240 GiB.
