Revisiting Solid State Drives

Super Talent's new SSD drive offers 128GB of storage, a significant increase in size from the first SSDs to hit the market, as well as cost.  They estimate ~$4600, though I guess that is cheaper than 128GB of RAM.  When The Tech Report did their testing, they proved that the drives technology has come a long way from the first batch, and it's random access times are awe inspiring.  Unfortunately, the drive cannot perform that well for all of the tests.

"For example, hard drives feature platters that take a fair bit of energy to keep spinning at thousands of rotations

per minute. Power consumption is of course a greater concern for mobile applications, but it's become a key metric

for desktops, as well. Those spinning platters also introduce a measure of rotational latency that severely impedes

seek performance. The drive head can't just go and grab data from a given target; it has to wait for that target to

come 'round on the platter. And then there's the not-so-trivial matter of fragility. Hard drives have become

considerably more robust over the years, but moving parts are still prone to damage from jostling and other physical


Solid-state drives (SSDs) aim to solve the problems associated with hard drive mechanics by replacing them with

memory chips. On paper, it looks like a great idea. The first batch of SSDs did offer low power consumption and

quick seek times without moving parts, however, actual throughput was dismal and capacities were quite limited."
