Hm, i phrased that poorly actually. What i was meant to say is that, while RAID0 can increase both IOps and throughput, its effects are limited when using software that cannot use the potential of striping RAID, due to it processing only one thing at a time. This is something Windows in particular is susceptible to. In this case, it might be better to have one single SSD which is very fast, because it can speed up the I/O more than multiple disks in RAID0. You also wouldn't need to use RAID-drivers, which are not always doing the work properly (like with JMicron, Promise, Silicon Image, AMD onboard RAID drivers).
100 Vortex in RAID0 will be very fast, for sure. But it's very hard to reach 40MB/s when doing strong
random I/O, especially with mixed reads and writes in it. I calculated that 40MB/s Random I/O means in the worst case 81.920 operations, or 82 thousand IOps. No consumer-level SSD can reach this high with this kind of 'worst case' workload, though SSDs are alot faster in this than HDDs are, since they only do 100-300 random IOps, that's it.
I actually searched a bit about the Vertex. It's very different from the OCZ Apex and Core series in that it doesn't use JMicron controller but rather a controller from an Mtron-daughter company, Mtron is already present in the high-performance SSD market and is quite reputable. The benchmarks look alright, but the Vertex is ofcourse a low-cost consumer drive. Its really worth the money i believe. Though regardless of its sequential performance being on par with Intel X25-M, i do believe the latter can produce more IOps than the Vertex is able to, making it faster. It may even beat two vortexes in RAID0. Then again, two Vortexxes will beat the Intel on other areas and will do very well in throughput benchmarks like ATTO, HDTune, HDTach if you care about those (i wouldn't
).
It depends on the price i guess. With Intel's recent price cuts the X25-M has become a viable option too for a moderately expensive system. Then again, i certainly don't think two Vertex disks in RAID0 are a bad choice, they have a decent controller it seems and are very different from the Apex and Core series, which use the plagued JMicron controller.
