Here's a boot time comparison performed on same box:
Tier 1 SSD - 15.6 seconds (Vertex 3 Max IOPS)....
Tier 1 HD - 21.2 seconds (Seagate Barracuda XT)
Hybrid SSHD - 16.7 seconds (Seagate Hybrid)
On a newer box w/ UFEI boot, Samsung 840 Pros in RAID 0 are slower than all of them....broke the array (samsung's advice) and still not happy (26.7 secs) ....haven't had time to play w/ it tho.
For $120, I'd get the Hybrid. I have two lappies here, one with an SSHD and one with 240 GB SSD and 7200 rpm HD ..... can't tell which is which even running AutoCAD and whatever.

I won't build a box anymore with less than a 120 GB SSD, tired of peeps bringing them back 6 months later asking me to clean them off cause they are full..... even with the 120's.
Of course, to get those HD numbers ya can't use any old HD....the Barracuda XT and the newer 3TB barracuda (30% faster then WD Black) are needed to see that kind of performance.
