from today Western Digital Launches First 3TB Hard Drive http://www.informationweek.com/news/storage/portable/showArticle.jhtml?articleID=227900320&itc=ref-true
mentions that it is a FBA4096 drive (rather than FBA512 that has been standard for so long) & suggested retail is $239, $74/tbyte (2.5TB drive is $189, $76/tbyte) recent posts in comp.database.theory thread ... mentions future system and s/38. one of the early isssues was that s/38 treated all disks as one large pool (with potential scatter allocate across all disks) ... so system backup was all available data and single disk failure resulted in doing complete system restore (which was rumored could take days). Supposedly this was motivation for s/38 being early adopter of raid technology ... as countermeasure to single disk failure (since such occurance was so traumatic). http://www.garlic.com/~lynn/2010n.html#80 Hashing for DISTINCT or GROUP BY in SQL http://www.garlic.com/~lynn/2010n.html#81 Hashing for DISTINCT or GROUP BY in SQL http://www.garlic.com/~lynn/2010n.html#82 Hashing for DISTINCT or GROUP BY in SQL http://www.garlic.com/~lynn/2010n.html#83 Hashing for DISTINCT or GROUP BY in SQL http://www.garlic.com/~lynn/2010n.html#84 Hashing for DISTINCT or GROUP BY in SQL http://www.garlic.com/~lynn/2010n.html#85 Hashing for DISTINCT or GROUP BY in SQL even with million+ hr MTBF drives ... there is still some failures ... which has driven to RAID & hot-pluggable ... being able to transparently handle (mask) single disk failure (and do replacement and restore on-the-fly). some recent posts mentioning the fba512 to fba4096 move: http://www.garlic.com/~lynn/2010.html#1 DEC-10 SOS Editor Intra-Line Editing http://www.garlic.com/~lynn/2010.html#84 locate mode, was Happy DEC-10 Day http://www.garlic.com/~lynn/2010b.html#85 search engine history, was Happy DEC-10 Day http://www.garlic.com/~lynn/2010d.html#9 PDS vs. PDSE http://www.garlic.com/~lynn/2010m.html#1 History of Hard-coded Offsets http://www.garlic.com/~lynn/2010m.html#41 IBM 3883 Manuals -- virtualization experience starting Jan1968, online at home since Mar1970 ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: GET IBM-MAIN INFO Search the archives at http://bama.ua.edu/archives/ibm-main.html
