This SSD, being based on SLC technology, and not MLC like the other 90% out there, means it's ENDURANCE, write performance, and life-span are significantly better then the competition.
Having endured 5 different SSD's to date, this is without doubt exactly what I was expecting of an SSD when I took the plunge the first time.
Reads are about 250MB/s and writes are around 170MB/s. My X25-m had writes of only about 70 MB/s at best, which was disgraceful.
There is none of the SSD 'stuttering' of the operating system, which some of you may have come to know and hate, and program installs seem almost instant, save for huge game installs, which write 11GB at a time these days...
I just won't replace this SSD, until Intel make another SATA-based Extreme edition SSD. Currently they plan only to launch a PCI-e version @ 400GB I hear.
Some come on Intel, some of us are willing to pay the extra, for reliablity, and performance, so get with it! I want 256GB of SLC flash, on a SATA-3 interface!
