sandisk logo SanDisk is pushing for new, low power SATA interface

According to SanDisk, the SATA standard just isn't power efficient enough for mobile devices and the company is now proposing that a new low power SATA standard should be developed. The company wants to cut the power consumption of mobile SSDs by 10 times, which is no mean feat, but SanDisk expects this to be perfectly doable.

According to SanDisk, the SATA standard just isn't power efficient enough for mobile devices and the company is now proposing that a new low power SATA standard should be developed. The company wants to cut the power consumption of mobile SSDs by 10 times, which is no mean feat, but SanDisk expects this to be perfectly doable.

SanDisk claims that today's best-in-class low power SSDs consume 50mW and apparently part of the reason for this “high”  power usage is because the SATA interface doesn't allow SSDs to draw less power, even when they're not in use. As such, SanDisk is hoping that its SATA DEVSLP initiative will allow for lower power usage in the future with a proposed standard target of a mere 5mW.

What we're not following is the part where SanDisk starts talking about Ultrabooks, as we'd thought there is far more need for lower power SSDs in devices like tablets than in thin and light notebooks, although we're of course not going to complain if we get lower power SSDs in notebooks as well. So far SanDisk has gotten a couple of small industry players – Intel, Samsung and Microsoft – to join them in their effort to push the SATA-IO to further develop the SATA DEVSLP into a fully-fledged part of the SATA standard. It's of course going to take some time before this happens, but it's good to see that the industry is moving towards more and more power efficient hardware.
