Dell Inspiron Mini's Guts Reveal Upgrade Opportunities
On the upper left, you'll see the system's SSD, which we have identified (through perusing the BIOS and consulting with our friend Kevin Toefel of jkOntheRun) as a STEC UM-SSD. Unfortunately, we have the Linux version of the Inspiron Mini so we haven't been able yet to run a serious disk benchmark like HDTach or Sisoftware Sandra to tell us what the read/write performance is like. However, STEC's description of its SSD claims 85MBps read / 25MBps write, which would be a really great read time, but a rather poor write rate.
The really interesting thing about the Inspiron Mini's SSD is that it's attached via a mini PCIe slot so, if you can find a mini PCIe drive for sale somewhere, you can replace it or, bettery yet, add to it by using the empty mini PCIe slot on the lower left. We took an ASUS-Phison mini PCIe SSD out of our Eee PC 901and tried to pop it in, but found that the Eee PC's SSD was twice as long as a normal mini PCIe card and just wouldn't fit in the space allotted. We couldn't find a single vendor selling STEC SSDs or any mini PCIe SSD that would fit in this slot, but we know somebody's going to figure out a way to hack this.
