Hi,

Will two of these fit in an Empeg? How did you mount it? They look like the 2.5" Laptop Form Factor.

They draw about the same current as the Rotational Magnetic Media drives. The 5V to 3.3V Regulator is probably an LDO. Examples...

The Crucial M500 480GB mSATA drive is 0.95A. The Adapter is probably another 100mA = 1.05A


The older Laptop example drives are:

IBM TravelStar 4200RPM PATA 10GB 0.5A
IBM TravelStar 4200RPM PATA 12GB 0.5A
Toshiba 4200RPM PATA 12GB 0.7A
IBM TravelStar 4200RPM PATA 20GB 1.0A
Toshiba 4200RPM PATA 40GB 0.7A
Hitach TravelStar 4200RPM PATA 120GB 1.0A
Western Digital BEVE 5400RPM PATA 250GB 0.55A
Western Digital BEKT 7200RPM SATA 250GB 0.58A
Seagate Momentus 7200RPM SATA 320GB 0.451A
Western Digital BEVT 5400RPM SATA 500GB 0.55A


As shown, power efficiency has evolved over the years. Huge differences is storage capacity, with even less power drawn, even at higher platter speeds.


But then, some of us remember the old 10 platter plus servo platter pack disk systems. Some of them had 14" diameter media in an overall package with a handle to help remove it - they were heavy. 80 MB was very large capacity. And who can forget the 8" 230KB Floppy Disks like Shugart?

Back then GUIs were simple (fill in the protected display fields), unlike today's GUIs that suck alot of storage, but give a much better feel of operation. I prefer today's operation.


Thanks.
