Identification mark : hard-disk SATA & SATA2

H

hi how can I identify a harddisk that it is SATA or SATA2 ?

I am going to buy a seagate 80 Gb hard-disk . before buying what questions I should ask to the dealer ? :twisted:

basically I want to buy a SATA hard disk . so how I can be sure that he is giving me the right thing ?

please reply

support for SATA2 depends on mobo too....
which MOBO are u using...??

and as far as getting a right product is concerned,do NOT buy without its bill !!

boss almost all sata hdds in the market now are sata 2....but they are backward compatible if ur mobo dosent support sata 2....i herd of some hitachi drives which are not backward compatible..but u can distinguish easily..

I recently bought a 250GB HDD , it had a jumper for setting 1.5GBPS/3GBPS.. Im confused does SATA1 have 3GBPS speed support? I have intel 915GAV mobo.

The best way is to go to the website of the brand of the hard disk (seagate/wd) you wish to buy and check the model no. of the SATA II products. Simply select the model no. according to the interface speeds, buffer etc you want and grab it from the dealer.
It makes no difference to them. They base their prices on the hard disk capacity, brand and whether it is PATA or SATA (though lately, the latter also doesn't matter)
In this way I was able to get myself a Seagate Barracuda 7200.10 250 gig PATA.

no re the 915 series does not have sata2 support itll work only in sata 1(1.5gbps)mode and if im not mistaking the drive ur using either has jumpers set to 1.5gbps mode or they have been removed

SATA 1 -1.5GBPS
SATA 2 -3 GBPS

@Ambar and janitha . Thanks for the reply. So my HDD is a SATA 2 Running at 1.5Gbps mode

good for me that I bought SATA2 HDD

simple if it supports 3gbps its sataII

Can SATA1 and SATA2 HDDs be installed in one PC?

^ I dont think so. Because the ports will either be SATA1 or SATA2. There wont be any manufacturer who give both. Although in case of RAM its there in the market.

dood see either ur board will be sata1 or itll be sata2.....so no confusion....but yes u can force one hdd to work in sata1 mode using the jumpers....

also check whether the cache is 4/8/16 MB.
it is good benchmark for any harddisk (higher cache will improve performance)

Bought a 250 GB Seagate HDD and I saw there was a marking on it which says about jumper. Not to use any to make it work at 3 Gbps and use jumper to make it work at 1.5 Gbps . So I guess its a SATA 2 HDD. Your HDD has any marking like that ?
