Hello, here, I have a question for the storage experts here. I just got myself a new 2 TB external drive, type WD Elements SE, and there is something which puzzles me: this is the first time I use this type and its reading speed is significantly faster than any previous models. As I always do with new drives, I ran a surface scan of the drive and it took off with speed of 150-170 MB/s (previous WD models I possess start at about 115 MB/s and Seagate at almost 140 MB/s): but, what is most surprising is that it never slowed down towards the end of the platter, as all others did. As a result, it ended the scan also with around 150 MB/s, in just 3 hours 30 min, while other drives of comparable sizes took at least 5 hours.
The seller was one of the two biggest electronics retailers in my country so a scam (at least a deliberate one) is impossible. Could anyone tell me how come this drive never slows down towards the end of the platter? Did Western Digital implemented a way to avoid this in their SE models?
