Hi,

We got today an old NEC Tape backup station reading LTO2 tapes that's about to give up.

We received two quotes on diffrent LTO 5 Tape backup stations,

First one is a Quantum with 8 slots and LTO 5

Second one is a Overland with 12 slots and LTO 5, and it's about $1000 cheaper.

Both have bar code readers

1. question

What's the difference between these two (more like what's the better brand)?

2. question

Which one would u recomend?

3. question

What is good too know before buying?

4. question

Any other tips, other brands, tape stations etc. and why?
We are using a backup software called Presstore running on a Mac Pro and we have a mixed enviroment with both PC's and Mac's.
Today we backup about 3TB and growing.

Both Overland and Quantum are respectable companies. Overland have been around for a long time, and used to manufacture half-inch reel-to-reel drives, but now are more of a VAR that re-badges drives and puts them into its own autoloaders/libraries- so the actual internal tape drive in the Overland autoloader may in fact be originally from Quantum.

In terms of which to buy - how do the warranty lengths compare? What is the callout time for emergency drive service? Do the libraries contain full- or half- height drives (full is generally better - if you take the drives apart you'll see that the FH versions are usually made from sturdier components, as they are designed for heavier-duty use). What are the libraries' respective tape load/cycle speeds? How do the maximum read/write speeds compare? Do they have the same interfaces? Do the libraries have very different MTBF (Mean Time Between Failure) figures?

Is space an issue? If so, how do they compare for size? Is cooling an issue, or noise, or power consumption? Look at the respective specs for those, too.

BTW - Are you aware that LTO5 drives won't read your old LTO2 tapes?

Thank you, we'll compare and see which of these two will be the best choice.

About "Do the libraries contain full- or half- height drives"
What would be the benefit with a full -height drive? is it different tapes or has it something to do with how fast it can load a tape?

As for the LTO 2 tapes, we only keep a 2 week backup on the tapes and then overwrites, old files is being moved to an archive that ends in on a BD disc.

The main benefit of FH drives is their longevity. FH are released before HH and are aimed at early-adoption purchasers who are paying more because they're buying while the price is still high. Consequently, they're more demanding and more likely to be annoyed if the drive fails. Once the technology becomes established, the manufacturers bring out the HH variants, which are aimed at the 'value' market - ie, companies that are more cost-conscious. The build quality reflects this.

The FH drives are usually faster, too. But the HH variants often consume less power, as they're later models than the FH and consequently use more modern motors, the efficiency of which is constantly improving. They also need to consume less power, because their smaller form-factor makes ventilation more difficult and over-heating more likely.
