i was thinking of getting pcie based drives instead of sata
i think i saw a revodrive 3 x2 in viewnet .. 240GB .. the quoted price was 2.4K
any benefits over sata?
or get 2 vertex 3 in raid 0?
The benefits depends on how you used a PCIe or RAID-0. Home user or gamer? 99% of the time, it will be terrible bang-for-buck.
But a relative strength in all of those benchmarks doesn't necessarily translate into a positive gain in user experience. Does an extra 25% jump in testable data throughput cut your Windows boot time or make backing up a game on Steam faster by a corresponding percentage? Does it even directly translate into file copies that finish that much faster? Not at all.
So, here's the thing. Yes, there are clear cases, particularly if you're a power user, where owning a motherboard with 6 Gb/s is going to allow your 6 Gb/s-capable SSD to shine. However, if a friend were to ask us if he should hold off on an SSD purchase until he could upgrade his old Core 2 machine to something newer with 6 Gb/s connectivity, we'd say no. For someone using a hard drive today, a fast SSD (even one artificially hobbled by a 3 Gb/s port) will yield massive and immediate gains in nearly every aspect of computing.
Snagging one that does work with 6 Gb/s link rates ensures you get the most out of it after an upgrade, sure. However even Intel's SSD 320, based on an older proprietary controller constrained to 3 Gb/s remains an admirable piece of hardware.

We've used this chart before, but it tells a compelling story. There's a huge gap between the cluster of SSDs, the high-end hard drive in the middle of the graph, and the low-end hard drive in the upper right-hand corner. You have to zoom in quite a bit, though, to distinguish between high- and low-end SSDs. At the end of the day, even if you're a fairly hardcore enthusiast, there's fairly little sense in agonizing over which SATA 6Gb/s SSD is the fastest. As we mentioned, even Intel's 320 still stacks up remarkably well.
So banish any thought that you must save for the newest, most expensive, and highest-rated SSD. If you have the money for a platform upgrade, there are certainly measurable gains to be had from upgrading to a SATA 6Gb/s-capable motherboard and the best solid-state drive. On a tighter budget, however,
buying the SSD that everyone says is the fastest isn't as important as buying an SSD you can afford, particularly if it means replacing a hard disk as your system drive.
