But with block size 64KB read speed is 130MB/s. The thing I want to point is, that my second HDD drive with 64KB and 1MB block size always got 70MB/s. That means, that SSD drive has other speed problem. Even with 100x better Random Access Times than HDD it does not handle small blocks well. And real world test shows, that SSD on my computer are faster than HDD, but not as much as their specification claims.

It does depend on other components as well. If you got a blazing fast video card but a slow cpu you will not experience the speed advertised. I can only say that I'm more than happy with the read speed of the OCZ Series II SSD drive but that the write speed (or the consequences of that write speed) forced me to move write intensive tasks (temp, pagefile) to another directory.

When HDD has 70MB/s read speed, it is 70MB/s. I got 2x155MB/s SSD drivers, and read speed is about 130MB/s. Where's the math?

The latter mentioned technology has been very much refined (version 9, anyone?) that they already have managed to squeeze every bit of power-saving technique out of spinning those platters and moving those heads. In the meantime, the usual SSD consistently eats up the same amount of watts even when the host system is idle. The performance on the current SSD technology still doesn't hold up on its promises for all-aspect-gains over the older platter-and-head technology. I still agree that SSD is the future though, but there may need to be some radical changes too with respect to its interfacing with its host system.

You could have 32 GB for $50. Lets say, double that for the sata support and larger case. Where does the rest of the money go?

Frankly, I haven't owned a board without RAID since the 90's. These SSD drives look promising, but for now I can’t justify it over my 2-640GB Samsung Spinpoint drives in a RAID 0 array.

Well, except floppy disks. I'm really glad that I bought the OCZ Core Series II SSD with 32 Gigabytes. It has an incredible performance once you move many of the write processes to a different drive. A drive with a better write speed would really be appreciated to take advantage of it even more.

But will have to wait until the price drops significantly. Though reminds me of the days back around 1995 when I paid $650 for a 1GB SCSI drive! 1GB was a good amount of hard disk storage back then. :) Nice!
