I really don't see a problem adding 3.1 oz to a wearable.  I am assuming
that you could build the OEM drive right into a small wearable case, and
since it draws 3.3V you could wire it into your wearables' power supply
(with a toggle switch in case it doesn't go to sleep on it's own well
enough.)  these specs look prety kewl.

OEM Drive Dimensions 
Drive (LxWxH)   3.37in. x 2.126in. x .256in.
(85.85mm x 54.2mm x 6.5mm) 
Drive weight
(w/o Battery)   3.1 oz. (88gm) 

Clik! Mobile Drive Dimensions 
Mobile Drive (LxW)   4.6in x 2.75in 
Mobile Drive weight (with battery)   5.9 oz.  
Mobile Drive weight (w/o battery)   3.1 oz.  

Clik! Disk Dimensions 
Cartridge (LxWxH)   2.16in. x 1.98in. x .077in.
(54.9mm x 50.1mm x 1.95mm) 
Cartridge weight   .35 oz. (10 grams) 

High performance for fast data transfers 

Performance 
Average seek time   Less than 25ms  
Sustained transfer rate   700KB/sec avg.
1.22MB/sec max.
500KB/sec min. 
Rotational speed   2941 rpm 
Latency (average rotational delay)   10.2 ms 
Average start/stop time   1sec/.5sec. 

Able to survive the environmental extremes of mobile devices 

Operating Conditions 

Temperature 
Operating   -20 to +65c 
Storage   -40 to +65c 
Shipping   -40 to +65c 

Relative humidity 
Operating   10% to 90% 
Non-operating   10% to 90% 

Vibration 
Operating   1.0g P.P 5-17Hz 
Non-operating   1.3g P.P 5-27Hz 

Shock 
Operating   100g, ½ sine wave for 3msec 
Non-Operating   300g, ½ sine wave for 3msec 

Altitude 
Operating   Up to 15,000 ft. (4,572m) 
Acoustical Noise 
Operating   32 Dba at 1 meter (3.2 feet) 

Extremely durable and reliable 

Reliability/Service 
MTBF   100,000 hours 
Service life:   5 years 
Disk estimated shelf life   At least 10 years 
Data reliability   Less than 10 errors in 1013 bits 

Voltage 
Operating   3.3 volts

Speaking of storage, the clik disc/catridges/whatever seem like a good
idea.  40MB worth of data on a "disc" about 1.5" in diameter.  This
seems
like the type of technology that would work well for wearables.  Only
problems though is that the read/write unit for the clik currently
weighs
about a pound.  It can run off a rechargeable battery which is a plus
though.  If the read were able to drop in size so that you could plug
the
reader into a type I PC card slot, then slide the clik into the reader
it
would be perfect.  Has any one here had experience with them?
