Consumer HDD Committee Startup Purport IDEMA JAPAN Technical Committee
Startup Purport This committee will be established for expansion of HDD application and activate effective use for Emerging applications.
Activities Make absolute testing method which satisfy requirement of consumer system Definition of standard function Categorization of applications
Confuse Drive Engineer PVR Engineer? Mbps Hi Definition? Re-try MPEG-2?ms seek 3 stream Need standard measurement!
TIPS for Member Reduce development redundancy Activation of HDD business Set Company Reduce evaluation on each sight Easy negotiation about drive spec Easy select of HDD Tester Company New business for new testing method Device Company Standardize Device Reduce R&D redundancy Get early stage requirement information Drive Company Focus development target Standardize device Reduce material cost
2) (Open Discussion) Discussion about Consumer HDD Specs Capacity Cost Performance Reliability Copy Rights Management
Capacity Discussion Use Only Short capacity for Normal Recording Archived Program 3x12=about 36GB per year Short capacity for auto recording 21 hours for 1 week1=about 42GB (@6MbpsMPEG-2) Short capacity for HDTV Only 4 hours for 30GB@ HDTV(@24MbpsMPEG-2)
Evaluation for Fragmentation Discussion Use Only A B C D Data Transfer Rate (b/s) A B C D Time
2) (Open Discussion) Discussion about Consumer HDD Specs Each company s HDD is not same performance for AV application. LBA, Zone, Relocation, ERP etc ATA AV command set is good enough?
2) (Open Discussion) Discussion about Consumer HDD Specs Capacity Cost Performance Reliability Copy Rights Management
Reliability Different from PC STB Mobile Car 24 hours Intermittent
2) (Open Discussion) Discussion about Consumer HDD Specs Capacity Cost Performance Reliability Copy Rights Management
Application Categorization
Application Category (Example) Application Single Stream Quality Requirement Category-1 HD recording Pro-Sumer 24-30 Mbps 2 stream + 1meta,Data Category-2 SD recording DVD Level Ave. 6, Max 11Mbps 2 stream + 1 meta,data Category-3 Audio Juke Box Mobile < 256 kbps 2 audio stream + 1 meta
Category-1 (Example) Level-1 Level-2 Level-3 Data Transfer 1 stream 2 stream 3 stream Power Consumption Peak >10W R/W 5-10W Peak < 5W R/W 2-3W Peak < 2W R/W 1-2W Idol < 4W Idol < 1W Idol < 0.5W Reliability Set top Potable Mobile
3) Discussion for activities Definition of application(define target) Categorize Spec, Reliability Definition of Test Test method Benchmarking
4) Working Group Activities Categorization WG Categorize by application Define specification Commodity HDD&Device assessment WG Discuss Win-Win specs between set,drive & device. Testing WG Define testing specs Benchmarking Method Interface Spec WG Assessment for Interface
5) Activity plan for year 2001 Standardize AV specs by CY2Q Committee Once by 2-3month Continuous discuss by mailing list or BBS
