Hi Tech Gurus!,
My Query : WD 500 Gigs - Which one is the best?


Requirement :
I need it as a RELIABLE primary drive for EVERYDAY usage.Copy/Pasting atleast 10GB data everyday.
SATA III preferred since mobo has 2 of these ports.
Choosing WD since service reports are better.


My Questions: (please answer a/w a reason,I would love the technical explanation you have to offer

)
Answers from EXPERIENCED and current WD users really appreciated

1)Is Green 1TB better (more cache?) w.r.t. 500Gig WD Blue
2)Does SATA III give better speed than SATA II (how much improvement in REAL performance % or MBps)??
3)will there be much difference in speed/performance wrt Green (if not too much,I'll go for the cheapest one)

I am confused between :

Most of these aren't available on any of the Indian sites,any idea where I can get them in Mumbai??

BLACK

750Gb Western Digital (WD7500AZEX) 64Mb 7200rpm SATA3 (if AVAILABLE???)
WD Black WD5003AZEX 500GB 7200 RPM 64MB Cache SATA 6.0Gb/s (if AVAILABLE???)
Western Digital WD Black WD5002AALX(if AVAILABLE???)

GREEN

Western Digital WD Green WD5000AZRX 500GB IntelliPower 64MB Cache SATA 6.0Gb/s 3.5" Internal Hard Drive -Bare Drive (if AVAILABLE???)

WD Caviar Green 1 TB Desktop Internal Hard Drive (WD10EARX) @4.3k
WD Caviar Green 1 TB Desktop Internal Hard Drive (WD10EZRX) @4.5k
Western Digital Caviar Green WD5000AZRX 500 GB IntelliPower 64MB Cache SATA 6.0

BLUE SERIES

WD Caviar Blue 500 GB (WD5000AAKX) @ 3.6K

4)Any other drive you would suggest???
5)Also anybody knows about EXTENDED warranty from WDC?

Thanks a lot for your time and replies

1 TB would have the lowest Rs/GB ratio so that would be the capacity to buy. There wont be any difference between SATA II/ SATA III drive performance because HDDs cant saturate SATA II interface speed.

For regular use green/blue/black shouldnt have any noticeable performance difference. Either get the cheapest one or get the black if the price difference justifies the 5yr warranty (please confirm though).
 
What adityamunshi said.
WD Black series has 5 years of warranty which is much better than 2 years warranty on blue and green hard drives.

Thanks I guess its WD Blue 500GB then since it's within the budget.

WD blue 2 yrs should be good.WD black a little costly.

WD drives are pretty reliable, I recently switech over to WD when my seagate drive failed, I have the
WD Caviar Blue 500 GB (WD5000AAKX)
pretty much satisfied with it

Thanks for the reply.WILL GO FOR IT :)

Thanks again for the reply guys! :-D
 

Hi,
I was asking about other drives buddy.
Thanks for your response :D

I called up WD distributors and they told me 500 GB black unavailable in INDIA due to "low" demand.Apparently nobody buys "500GB" black.
Anyways,I decided to go in for 500GB WD Blue,will post my thoughts soon.

RATES I GOT -> 3375 WD Blue WD5000AAKX
5800 WD Black WD1002FAEX (claimed 3 yr warranty instead of 5,misinformed seller I guess)

Thanks :D
 
It's WD for me,got the BLUE WD5000AAKX!

WD5000AVDS - 3600
WD10EARX - 4150
WD10EZEX - 4150

I used Acronis WD Edition (free for WD users).you can download it (search on google for link) ,about 147MB file.
It will work ONLY if you have on WD drive detected by the BIOS.
After connecting,boot up and install it.
Use AUTOMATIC method and clone it,change boot to new drive and VOILA!
(SuperTip -> Check for ERRORS on the source disk and repair them using CHKDSK before copying/cloning/imaging)
Everything works SMOOTH!

Booted from the new drive.Changed old drive letter names.
It's all good now
