Known-good drive manufacturers, known-trusty PC review sources

Dad used to use 1" tape on a data drive. The reels contained

He used two floors of them after the two floors of disk overflowed.

Floors - in a building larger than the Great Pyramid! Big radar installation.

Three parallel processing Computers streamed processed data for storage to review.

NASA uses the radar now - as a watch guard for satellites.

Yeah, that's a somewhat unknown fact- with this kind of RAID setup at best your MTBF is actually divided by N for N drives because it will stop until you feed it a new drive to its satisfaction (good luck if it dies when nothing similar is easily available). Even if you don't lose data, you can lose a lot of time. Being of the BFI persuasion, I just mirror the drives with a daemon that copies from A to B, no RAID, no fuss. The S.M.A.R.T. parameters are monitored automagically with another daemon that sends me an e-mail if things start looking dodgy on any of the drives. Dumb, but, hey very reliable so far.

In my day, we defragged core memory by hand, with magnets.

It kind of depends on what you mean by "back up".

I back up my work (religiously!)

But there's no way I'm going to back up the entire 225 thousand files on this machine - and think I can actually do a restore from that and have it work.

Or if you're on a budget.

The rubber button on the print hammer of my ASR33 turned to goo, possibly because I reinked a ribbon too heavily with stamp pad ink. I made a mold and hot-pressed replacements made from rubber windshield washer hose. I weighed out the rubber, heated the mold until a drop of solder on it melted, then squeezed it in the bench vise. jsw

Your nickname should be "The Vulcanizer". ;-) Or "Mouldy Madman"

When I worked at a W.U. Telegraph Co. repair center as a TTY repairman I always had to replace rubber print hammer. It either was gummy or too hard. If it was gummy it smeared over the type wheel and if it was too hard it would damage the letters it hit.

I backup and restore full machines regularly and they always work perfectly. Granted these are not Windoze machines, but the folks in that area also do full backups and restores without issues as far as I know.

We've got libraries that hold hundreds of tapes, not just 5, be even with that the primary backups are going to disk based with data de-dup. It's faster and takes less floorspace in the DCs.

The first 4 hard drives I ever bought were over 10x the size of the last. Now we have to wait 5 years for a 50% increase.

What kind of POS controller stops servicing the host(s) if one member of a mirror set dies??? I've been using "real" controllers for many years and they never stop servicing the host(s) for anything short of loosing both members of a mirror. Not even a controller failure stops them since the controllers themselves are redundant and the remaining controller will pickup the load. A failed disk will be automatically replaced from the spare set and the mirror will be back to full redundancy in short order. You get to select on a unit by unit basis whether priority should be given to shortest reconstruct time with some performance impact to the hosts or no performance hit, but longer reconstruct time.

Well, I have to admit that saying it as "only 4,700,000k" sounds much more impressive.

Wish we could get the media to start reporting the National Debt as "16,000 billion" rather than "16 trillion". ( Of course, "four times the Federal 2012 budget", and "nearly seven times the expected Federal

In Europe they use the term "thousand million" rather than billion.

(for 1x10^9)

It would take days!

A few hours at most using "real" tape drives that sustain 10+ MB/S throughput.

The best current practice is to use an SSD for your operating system and programs, and use a conventional drive for your personal data (what you can separate from the primary drive).

I buy namebrand hardware and look at reviews for the specific product I'm interested in. Newegg and Amazon are my two currently favorite online shops. Reviews are not always accurate, even the consensus can be wrong, but you can get an idea of the pluses and minuses of a particular product by looking at both positive and negative user reviews. I value negative reviews, by determining whether the alleged problems are something I can live with. Otherwise, you get what you pay for.

yeah right.

If that's really possible, it's gonna cost wads...

I always get a bit paranoid when someone refers to "real". :)
