And a LOT of SSD's have been shown to not provide any significant boosts. And of course, cost defeats all.
The moral is, I'll wait for numerous others to attest to a SSD being all positives and no negatives over a HDD. Until then, I'll use what's tried and true.
Apparently, you haven't done any research if you are waiting for these nebulous "others" to attest to the performance advantages of SSDs, because there are plenty of reviews. The big problem with SSDs in the consumer/prosumer market is primarily an issue of perception. Saying
"a lot of SSDs have been shown to not provide any significant boosts [over HDDs]" is irrelevant
because every SSD model is different. Unlike the mature technology of platter-based harddrives in which it is fairly easy to determine performance and power usage by size and rotational speed, and which all are pretty much built with similar architecture,
the technology utilized in flash-based SSDs is very diverse -- All SSDs are NOT built alike. In addition to utilizing either SLC NAND flash or MLC NAND flash, the largest component of an SSD's performance lies in how advanced the flash controller hardware is and how many independent channels it uses. Besides the huge range of performance, different SSDs also use dramatically different amounts of power, again based on the architecture, flash controller, and optimizations.
Perhaps many of you on this forum are uneasy about SSDs because unfortunately Apple used a very poor performing 64GB SSD in the original Macbook Air (not sure about the new one). Well, do not let that color your perspectives of all SSDs, because there are many that are MUCH faster from companies like Samsung, OCZ, Supertalent, etc.
Intel's name gets thrown around a lot because they have entered the SSD market (in a partnership with Micron technology) with next-gen flash controller technology that has blown away speed records. And one of the biggest advantages of Intel's SSD technology is that they have been able to get much better performance out of the vastly cheaper, higher-density "MLC" type of flash. As seen here on an initial Anandtech review, the 2.5" 80GB
X-25M (the cheaper MLC version) absolutely
blows away many of the fastest 3.5" 10,000RPM harddrives on the market. Compared to an average 5400RPM laptop drive, this thing is in another league.
