Now, several manufacturer announced their SSD. With a big slogan, higher transfer speed. But actually, now, intel must be the most successful one.
Intel X25-M,X25-E,X180M SSD provide high speed, good reaction time and longer lifecircle. The read-out speed of most SSD now is just around 110MB/s, and write-in just 75MB/s. But these three, provide a pretty higher speed than others. The X25-M, X180M read-out speed up to 250 MB/s, but write-in only 70MB/s(lower than others). One more thing is that its stability is not good enough. Maximum read-out speed can up to 250MB/s, but minimum speed only around 110MB/s. A very big drop. In the contrast, write-in speed seem stabler. The X25-E, for enterprises, read-out speed also 250MB/s(stabler than the other two), but write-in speed up to 170MB/s. And by the way, Intel lengthen the SSD's life(with Advanced Dynamic Wear Leveling function). But also, its capacity only can up to 250GB, like the other make, WD, Transcend etc. So, that is still a big problem now for user.
