SAS HDDs

[ikix]

There is some £16ish difference between these two hard drives and the only thing i can see that is different is the tick under "SAS" in the specs, what is it and is it worth the price?

Non-SAS
SAS

SAS is serial attached SCSI.
If you're just using a standard SATA Port on your mobo, i dont think it makes a blind bit of difference.
The 320NS is the enterprise level version of the AS.
Go for the cheaper one

Not sure where the serial port comes in - unless you meant SATA port.

SAS is Serial attached SCSI and is to convential SCSI what SATA is to IDE - a serial interface for hard drives that uses the SCSI command set and protocols.

At present it is slightly slower than SATA but next generation drives willbe faster. SATA drives are supposed to be able to connect to a SAS backplane, but not the otherway round - so if you wnat to use SAS, you will need an SAS controller card.

sorry yeah, meant sata port
i've got serial ports on the brain just now with this project for uni!
i'll edit the post to avoid confusion!

peter, when you say SAS card, would that be one of the cards which uses the funny connector with 4 SATA ports coming off of it?

I think the tick next to SAS is either a mistake or missleading.

If it isn't a mistake then it means that the drive can be used with SAS RAID cards/systems that can take standard SATA drives. There are a good few cards that can do this. And if thats what it means then in reality any SATA drive can do this, it's just the more expensive drive has a better warrantee and is recomended for 24/7 enterprise use.
