Need your assitance - open letter to Hard drives manufacturers
Hello all,
This is long - I would appriciate if you will tahe the 5 minutes and read it. Thank you.
I just thought of making a group petition to hard drives manufacturers.
I have been into computers for the last 20 years or so. I have seen many hardware/software problems.
one that really gets on my nerve is the Hard drive quality theses days.
Drives of good make - don't make up to their first "birthday".
In the other hand old hard drives are with far better quality and reliability. I still own and Use my good old WDC23200 (3.2 Gb) and the WDC21600 (1.6) - I had no problem with them whatsoever. to add on it - both drives are most of the time inside my Motocycle cases - I use them as portable data storage - with case. In the motocyclke trunk "they" suffer from high temprature and G and shock. Still no problem whatsoever.
New drives are Fast, cheap and have large capacity. But their quality is bad. and this is by far the down on new hardrives. Hard drive is the most important thing in your system. It holds your OS, application and most important your Data. so what good is a Data container if it fails to do the primary intention.
this is also true about SCSI drives - thier quality is not what used to be.
I don't know what is the cause - but I have a feeling that this is Due to the High rotational Speed. Magnetic density and heat generated by new drives.
I would like to ask all of you tech Guys and Girls from around the world to join me on a open letter to hardrives manufacturer. explaining them that the sittuation is unbareable.
Hardrives manufacturers should take their enginneering effort and put it on reliablity and durability. and not upon speed and size.
Thank you all,
Gabriel Levi
Our strengeth is in Numbers (Tactical thinking...) ;)
Ps - NooNoo/scott, if you feel that this subject is not good fot the tech longe or the Windrivers BB - contact me.
RAID =safe .... No it doesn't ! RAID = FAST

4) I've been using computers since the late 70's when I was just a young lad, but one of the first and most important things I've learned is to ALWAYS ALWAYS backup your data. I don't care if it's a floppy, 173mb hdd or 200gb hdd,... When it comes to data loss, the ONLY prevention is backup, backup, backup.
To point 3 : NO ! NO ! NO ! NO ! NO! NO ! NO ! NO !
Is that enough times ? RAID is NOT 'safe' in data terms, it is less safe than a single disk .... Read MacGuyver's post above!!
But at least you know BACKUP is important !
I've finnished my rant now ! You can come back out now Webhawg ;)

raid 1, 3, and 5 are a safer form of backup then a single hard disk, however, these only protect from hard disk failure... NOTHING ELSE. Viruses, Wrong clicks and power surges will not be protected. The advantages of raid 1, 3, and 5 are more in the disk access speeds for servers then they are for backup.
A proper backup solution has an EXTERNAL system to backup the data and if posible, offsite. I've seen a few setups where servers are tunneled together across the internet, and use each other for backup..
I currently use multiple methods of backup.
The critical stuff sits on my raid 1 array and is copied on my laptop also, my data storage drive is in a hard disk caddy in my system and is easy to take out.
Sure, if my place burns to the ground, (and my laptop was left there) i'd loose my data, but i think if that happened, i'd have bigger concerns then my e-mail from several weeks ago. Each person has to decide HOW important the data is, the more important, the more steps one needs to make in order to protect it.

Maybe you need to reread Mac's post. RAID is safer than a single disk. RAID 0 is the only RAID that is less safe than a single disk, because you rely on the availability of 2 disks to maintain the volume.
Backups complete the safety, which the Hawg made very clear in his post.

Ok you got me,.. well sorta. What I meant by that is that RAID (depending on which type or how many disks, etc.) is safer then just relying on one single harddrive without RAID to store your data on. If you have 2 drives, and all your data is mirrored to both drives and one drive craps out, then at least all that data isn't gone. But anyway...
Now that I've explained that, you can now feel free to walk away with your tail between you legs confus-ed. ;)
