magnetic media?? for home use? like what. Just askin:)<br>
I have about 70GB of photos that I have right now on a number of USB<br>
sticks.. the 64GB stick took 24 hours to complete the copy command..<br>
oops, sorry, just checked, now it is 92GB of photos..<br>

Yep, magnetic media :)<br>
<br>
Since the whole thread was focusing on long term storage with some of<br>
the stored data being decades old I opted to point out the problem with<br>
the goal versus the media. If this data is to continue to reside in<br>
some long term storage then flash is right out because of its retention.<br>
<br>
The other topic point was the value of the data to the end user. The<br>
thread overall makes a suggestion that the data is irreplaceable and<br>
therefore quite valuable to the end user so I went with that, too.<br>
<br>
Option one is a spinning hard drive. Plug it in, back up the data,<br>
power down and store in a cool, dry place. If the long term storage<br>
backups are very infrequent, the drive will last many decades and the<br>
data retention is high for the platter media in proper storage<br>
environments (20-25 C, 40-60% RH non-condensing or dry nitrogen if you<br>
go all out).<br>
<br>
Option two is tape. You can use the DAT format like DAT-160 which stores<br>
80GB uncompressed per tape (and may be cheaper than the more recent<br>
DAT-320 -- 160 GB per tape.) HP currently sells a DAT 160 drive for<br>
$700+ while DAT 160 tapes are about $40 each.<br>
<br>
DLT is another option for tape media. SDLT I is 110 GB per tape, SDLT<br>
II is 300 GB, or go so far as DLT S4 which is 800 GB per tape. There's<br>
a drive on Amazon for about $500.<br>
<br>
LTO is yet a third option with some giant capacities in the later<br>
versions. LTO-1 is 100 GB uncompressed and the current LTO-6 is 2.5 TB<br>
(not GB, but TB). LTO would be one of the most current though an older<br>
LTO-1 or LTO-2 drive could be purchased.<br>
