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 abuse.
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.
Now a new wave of SSDs is upon us, led into our labs by Super Talent's SATA25. This 2.5" drive packs a stunning 128GB of total capacity and claims sustained read and write speeds of 60MB/s and 40MB/s, respectively-huge improvements over previous solid-state drives. But how does it hold up in the wild? We've run the drive through our comprehensive suite of performance, power consumption, and noise level tests to find out.
