Hard disk drives
« on: 21 October 2009, 13:18:48 »

I am looking for a bit of advice from the experts on here.  IT build quality varies from time to time.  When I was really into this stuff Seagate and maxtor were considered the best for reliability, nowadays I dont know...

I am looking at beefing up my PC when I am next in the US.  I reckon I will need 2-3TB (the missus has a lot of music and I have a lot of films)

Which makes/models do people recommend?  I will be there for Thanksgiving where the sales are just ridiculously good !  :y

TIA  :y

My fav have long been Western digital.

last time I looked they still offer one of the best warranty's too.

to me that shows confidence in the product.

ive used their returns once for a fault, very quick and easy.

Or a marketing ploy to push sales and possibly get an extra quid or 2 for the drive (which is the more common reason).....ala Dyson just recently!

Try and find an enterprise drive, rather than a home user one.

The difference will be the MTBF (mean time between failures). Most manf's will tell you what the MTBF is on the website. If you aren't having any luck this way, find the range of models used in low end servers and try and locate those when you are in the US. TBH I would have thought it would work out more expensive to buy in the US with the exchange rates ATM.

Also might I suggest that if you are going to have some much data on a PC, that you consider a hardware controlled redundant raid array. Or you could end up with no data.

Any MTBF (as per Telcordia and BT HRD5) on an item with moving parts is meaningless, its a measure that is only truely relevant to fully solid state items.

The exchange rate is good for USD, not for EUR.

MTBF is only useful really if you are managing large numbers of systems with lots of drives as its an average.  If you only have one an average of the failure rate means much less than if you have 1000.

So Samsung or WD.  Noone going to pipe up for Seagate? ::)

edit: The Thanksgiving sales are huge regardless of exchange rate :y

As said, ignore MTBF of items with mechanical moving parts as they mean jack.

Reason being is that the life is very dependent on the type of useage and installed environment.

Remember also that an MTBF of say 5 years does not mean it will last 5 years, it means that at 5 years a goo percentage of those made wil already have failed!

MTTF would be a more interesting figure......but few supply that!

Cheap Sata interface :
Samsung and Western Digital..



Expensive SCSI:
worth only if you use 15K RPM disks like Seagate Cheetah.. But prices are high really..(Used in servers)
also raid controllers are not cheap..But imho not necessary for home use..Unless you are TheBoy..

SSD:
they are fast but capacities are low..

note : you must use  a mobo supporting raid level 1..

(if you are not after high performance)

for data protection..with that you will use 2 same capacity disks (1 original 1 for mirror) .. Sata is ok for that ..
