Dell has officially started selling its new 2.2-pound Latitude E4200 this week with solid state drives as the only storage option, accelerating a trend in ultraportables away from hard disk drives. The popular ThinkPad X301 also comes with solid state drive options only. The SSD options on the E4200 come in two flavors, standard or "Ultra".
Dell pre-announced the high-performance Samsung Ultra SATA-II solid state drive in February. The SSD is able to read data at 100 megabytes per second (MB/sec) and write it at 80MB/sec, 60 percent faster than SATA I drives, according to Samsung.
The new SATA II SSD can resist up to 1,500 Gs of shock in a half millisecond compared with a shock resistance rating of 300 Gs in 2 milliseconds for a typical HDD, Samsung said.
