Well u guys could u help me pick up a couple of disks [80GB] for setting up raid..

which amomng these is the best
1. Hitachi
2. seagate
3. samsung
4. western digital (if its not too costly, NO RAPTORS)


 
Everything is going to be an opinion, as there is no real clear best. Everyone has had different experience with different drives. No drive is especially good or bad right now, as they all have their failures. Get something for a good price, and with a good warranty...
 
I have both re2 and seagate 750gb in raid 1

RE2 -
With 1.2 million hours MTBF, 100% duty cycle, 5-year warranty

Made for raid adapters
RAID-specific, time-limited error recovery (TLER) - A feature pioneered by WD, significantly reduces drive fallout caused by the extended hard drive error-recovery processes common to desktop drives.

Seagate ES Only, regular 7200.10 has less duty cycle
Less duty cycle 73% @ 24/7

only the ES are made for RAID, the regular will have drive fallout issue if you use it on a raid controller

Duty cycle are important if your pc/server stays on 24/7

All drives fail, thats why you use raid 1.. 🙂

Right! Or get a pair of 160s and have RAID1.

Choice of brand today makes little difference. Whoever gives the best value and warranty.

 
MTBF doesn't mean much to me, 1.2M hours = 50k days = 136 years? Doubt a drive is going to spin for 136 years of uptime. The measurement is of course average failures based on testing or warranty or some other measure, but it doesn't seem meaningful to me, other than longer MTBF = less chance of fail = good.

Exactly. And besides...most 80Gig HDD's are going to be almost as expensive; the price per gig is absolutely horrible at that low end.

Is there any particular reason why you want to run RAID. Be forewarned, it is a hassel a lot of the time. There is the "cool" factor and that you get some experience, but in a lot of cases it causes some problems.

the best price / $ for drives (assuming you live in the US) is the 250 or sometimes the 320. Both can be had for under $100.

RAID is only worth it if you really need extra speed (working with uncompressed HD video for example requires a minimum 3 drive RAID 0), or really need the peace of mind of RAID 1.

If it's just for your media drive it's really not worth it.

Still, it really is cool 🙂

for not a whole not more money than a single 80gb hdd you can get a 25gb or a 320gb hdd....320gb is usually the sweet spot for price/size but 250gb also hits a fairly sweet spot.........buy one of those instead IMO

it does mean something...

ibm publish their deathstar mtbf based on 11 hour usage daily... the big fiascal was that people were using it 24/7 and they started to die early..

check chapter 9.4.4 life, page 64 / 209
http://tomen.net/reference/d60gxp_sp.pdf

333 power on hours per month

333/30 = 11 hours a day.. wtf does that mean.. u can only use it for up to 11 hours a day ?

and out of the 11 hour, you can only use it 20% seek, writing, reading operation.. ~ 2 hours a day.

 
you guys should read this

Even the so called "Nearline" (Seagate) or "Raid Edition" (RE, Western Digital) SATA drives which are made to operate in enterprise storage racks, and which are more reliable than desktop disks, are not made for the mission critical, random transactional applications. Their MTBF (Mean Time Between Failure) is still at least 20% lower than typical enterprise disks, and they will show the similar failure rates when used with highly random server workloads as desktop drives.


the re & nearline definitely has more or higher reliability than the desktop drives.. seagate proved it..

 
Depends what you backup.
I only back up essential files, not the whole disk.
My main drive went belly up with bad sectors so now I've set up a Raid1 array - if one drive goes down I can mirror the whole lot to a new drive.
Obviously this won't protect against a major malware/virus attack, but will stop the hassle of a couple of days reloading all the stuff.

I've always been a fan of Quantum, then IBM, so now Hitachi.

Regarding price here in the UK an 80GB drive is about £30, 160GB about £40.
Then I guess it depends what size your mobo/os detects up to and whether you use fat32 or ntfs.
