ThinkPad X200 – What Kind of SSD Does It Come With and Is It Good?

As Phoshi mentions, there is probably little difference to random read/write performance. It's possible that with RAID0 the sequential write speed increases, because it is relatively low on the Intel X25-M drives at about 80MB/s max. However, the effect of using the drive over time, causing fragmentation, is shown here (see the table near the bottom): TRIM would help mitigate this performance drop. Also, there are the usual caveats with RAID0, such doubling the chance of data loss due to drive failure and the RAID controller itself being a single-point of failure.

This is similar to Dell and HP, but instead you hold the power button in for 15 seconds with the AC and battery power removed, it discharges the motherboard of any residual voltage, sometimes this fixes small bios issues.

For a more complete bios reset, remove AC power, main battery, and then the cmos (RTC) battery, leave the cmos battery out for 15 minutes before re-connecting it. You will need to immediately enter the bios and set the date and time after this procedure.
