There's been quite a bit of dialog on SSD performance, but no mention of the associated hardware requirements to achieve that performance.
To get the advertised transfer rates on the Samsung 840Pro for example, you need a very good SATA 3 controller. Quite a few of the controllers on recent motherboads, despite being SATA 3, have abysmal performance, the Marvel 9128 SATA 3 chipset on my Gigabyte I7 board is slower than the SATA 2 interfaces on the motherboard.
I've investigated aftermarket cards, but the only PCI slot suitable on the motherboard is used by my video card, the performance demands for add on PCI sata 3 cards are very high. I'll be looking at replacing a perfectly good i7 (socket 1156) and motherboard to get the full performance from the 840Pro, as soon as the latest socket change happens (due over the next few weeks apparently)
In the meantime, I'll install the 840 on a SATA port and take a slight hit on performance, not as bad as the benchmark figures would suggest from what I've read.
