1Tb drive??

Post by **ADF-Baby** » Mon Nov 26, 2007 10:14 pm

i was online the other day looking for a new harddrive and saw that they now have 1Tb drives was wondering what the relyability of these would be? I mean the drive is the same size as a normal one so how do they fit all the extra info on it? is it higher compression on the drive ie. tracks are closer or are there more thinner disks in it?

hey all,
Guys, 1 TB is mainly used for servers and also for Digital video editing since 1 sec of DV takes up to 172MB, and the new coming DV format is called High Definition and this comsumes much more than normal DV.

there is a new technology out that will give you a lot more space...the best way to explain it think of 4 blocks of chees laying down in a circle (circle being data arount the disc) now take those blocks of cheese and stand them on there end....you can see how much more data you can fit...i dont know whether there using this technology yet but if i was you baby i would think about buying 2 500GB discs to start with and buying a drobo..........

I have yet to see a better solution for storage, this is the true meaning of plug and play in my book

Ill be getting one and it is absolutely awesome

The only downsides to it see is that it uses a mirror raid system. It may use less space for its mirror data/protection the hight amount of space you have but if you have some odd drive configs you could be wasting alot of space.

For example

Drives: 80 GB + 80 GB + 80 GB + 1.0 TB = 1.2 TB
Drobo: 221GB

Drives: 1.0 TB + 1.0 TB + 1.0 TB + 1.0 TB = 4.0 TB
Drobo: 2.7TB

Good if you want data safety and you have similar drive sizes. Bad If you just want size.

go here fridge

4 x 1TB = is really only 3.6TB

so you get 2.7TB of actual space and 931GB used for protection, its basically Raid 5 by the looks of that using Fault Protection Id say

Specifications:
Drives: One to four 3.5” SATA I or SATA II hard disk drives (full or half-height, no carriers required): Any drive manufacturer, any capacity (mixed capacities ok), any spindle speed or cache
Interface: High Speed USB 2.0
Dimensions: 6.0” wide x 6.3” tall x 10.7” long
Weight: 6 lbs. 11.3 ozs. (without power supply, hard drives or packaging)
Includes: Drobo storage robot, external power supply (100v-240v) with U.S. 110v power cord, USB2.0 cable, User Guide & Quick Start Card (printed), Drobo Resource CD with Drobo Dashboard application, Help files, How-to Videos and electronic documentation.
System Reqs: Apple Macintosh OS-X 10.4 or greater; Microsoft Windows 2000, 2003, XP or Vista

Approximate capacities: mixed drive sizes: Rated Drive Capacity (space available for data with redundant protection)
- with 3 drives (mixed capacities): 250GB + 300GB + 500GB = 1TB (510.2GB space available for protected data)
- with 4 drives (mixed capacities): 250GB + 250GB + 500GB + 500GB = 1.5TB (929.0GB space available for protected data)
- with 4 drives (mixed capacities): 250GB + 300GB + 500GB + 750GB = 1.8TB (975.6GB space available for protected data)
- with 4 drives (mixed capacities): 500GB + 500GB + 750GB + 750GB = 2.5TB (1.6TB space available for protected data)

Mind you you'll pay for it around $800 i think...

1 Tera drives are good, but not really quick - good for storing movies and music etc... but if you are going to be using them a "working" drives for file manipulation there are faster, cheaper solutions available.

I got a 750Gig a few weeks ago, awesome for storage all my... um... movies....

But I won't use it as a drive for working with files, just a place to store info....

the drobo is separate drives not 1 x 1TB drive and there sata 1 and 2 compatible....it would be plenty fast enough, but this is the ultimate in my opinion.....there are cheaper alternatives out there like cable said....this is just the one i want

I think I found a good cheap alternative, hasn't got the hot swap ability so turning it of the swap drive is a must. They say it can only use drive 750Gb max but i say they said that before TB drives where available.

You can get on for roughly 120$. its also got RAID 0 and 1 built in if you want them.

The other alternative is to get an old pc and put hot swap drive bays in. Right now my case has 13 spaces for hard drives with any modifications.
