The result is also a lot bigger, single layer BD-R media is still
expensive and my quick peak didn't even give me a price for writable
dual layer media (is it available yet). You also need a BD-R writer
which I also presume isn't exactly free.
Last i priced one at Best Buy it was $200+ whereas DVD writers were
mostly in the $50 - $125 range.
I checked on Newegg and I see what appears to be good quality DVD
burners for $20-23 (plus freight). Their cheapest Blu-ray burner is
$210, about 10 times the price of DVD burners.
Blu-ray media is also a lot more expensive, you get premium single
layer DVD+/-R for $0.40 to $0.28 per disk with 25/100 "cakebox".
Premium dual-layer is about $1.45 per disk (20 disk "cakebox").
BD-R media is about $8-$11 each, not quite 10x of the DVD DL but not
far from it either. They have only one type of BD-R Dual media, at $38
for a single BD-R DL disk (ouch).
You can put it on a hard disk, modern hard disks are big and cheap
enough that it's not TOO bad
Someone - WD? - just introduced a 1.5Tb disk for under $180 list.
Seagate introduced the first 1.5TB disk a while ago but they only
recently became available for real. I see it's listed at $179.99 at
Internet retailers for the bare drive, so no signs of downward drift
yet. But then it's actually the same cost per GB as it's smaller
cousins which is quite amazing (and not the historical pattern).
But even 1500 (salesman) GB can get eaten up pretty quickly if you try
to store Blu-ray disks directly, you could get about 30 full
dual-layer disks on it (or 60 full single-layer). Not all disks are
full so perhaps on the order of 50-75 Blu-ray dumps?, not quite as bad
as I though actually :-)
But storing it on disk even in origina form is actually much cheaper
($0.12/GB) than burning on Blu-ray media ($0.32-0.44/GB or $0.76/GB
for dual layer), in fact the per GB cost is actually lower than that
of DVD dual-layer media ($0.17/GB). Only single-layer DVD beats it at
$0.06-0.085/GB. All those assume 100% full burnable media, in all
other cases the comparison prices would be higher.
I think the 500 GB 2.5" (9.5 mm thick) disks are in many ways more
impressive actually, both WD and Samsung have them now. Hitachi has a
400 GB but it's 12.5mm thick which makes it too thick for many
laptops... Only 5400 RPM spindle speed though, have to go down to 320
GB for 7200 RPM models which is still impressive.
The 5400 RPM 2.5" disks uses less power (no fan), small formfactor,
sturdier and quieter. The only drawback is price really, 320GB 5400
RPM disks gets down to $0.22/GB but the 500GB (and 7200 RPM 320GB) is
$0.30/GB. Even those still beats the cheapests single-layer Blu-ray
media though.
