) 2-3 yrs IMO for kindofblue
Kind Of Blue
Well they wont really "compete" with normal HDD.. THey are a better technology so they'll *phase out* magnetic drives. You're talking of affordability; yes right now its only for the early adopters.

First Law of Economics. Mass production of generics = low prices.
I am still stuck with a sata1 disk. But compared to my ide ones, it is fast.
sata1 works at 150MB/s , IDE does 133MB/s @UDMA 6.
the only thing SATA is good at is burst speeds, how noticeable is this anyway ?..if u already have a 16MB buffer on either of the drives. SATA2 isn't all that much faster either. Overall there isnt much to be impressed about.
Assuming ur talking 7200RPM drives

It's that and a little more. Demand and supply dictates at one level. But there's also the notion of "hottest" in teh market. So you get something just a rung below the current 'object of desire' and you get reasonable VFM.

One gets to notice it in processor releases. I observed this happen with AMD dual cores.

@blr_pTell that to my machines. On one, I have a 160GB SATA1 drive + a 80GB IDE one. The ide one is slow (I see the difference when copying files). The sata one is fast (os loads quickly). On another, it is ide all the way (a 40-80 combo). And it takes ages to boot (considering the f/w, a/v etc).And I am talking 7200 rpm drives here. I have only one 5400 rpm drive and that is 6+years old. The difference might be coz of the interfaces supported by various m/bs. Not every board supports ATA133, even if the drives do.So, maybe there is not much of a difference. But who cares. I want fast disks so that I don't have to wait for files to copy and the os to boot.@ramaseshanYep. Who will buy diamonds if they are sold at street corners? The 'flaunt value' premium. It is another economic fact.

Well going from a 80GB-->160GB will give you an increase of at least 20% on load-up right there (even if you stuck with IDE), for the simple reason that the head has to move less since the drive is denser, same with other reads, writes etc. If as it turns out you were running at 100MB/s or UDMA 5, then yeah, you expect at least a 50% increase going to SATA and the fact the HD is now dbl the size of the previous one.
To know what your current speed is, get HDTune and look at the Info tab
..bottom right where it says 'Active', this is your current transfer rate, Normally supported & Active should be the same otherwise you're running at under system performance.
You could even do a benchmark with HDTune, the only meaningful metric is the avg. transfer rate.
If you want faster performance then you need to up the RPMS of the drive to 10k or even 15K, but be prepared to get hit in the wallet
As to prices for the 1TB i guess it would around Rs.12k, the 750GB recently dropped to 9.5k.

As a technology, SATA and IDE are two different beasts. I do have yet another machine with a 160GB IDE drive plus the 20GB (6yr old hd I was talking about) and that won't win any 'fastest drive in the world' prizes either.In real world circumstances, IDE depends on what devices you have on the same channel and the max speed supported by the m/b. To my knowledge, if I have a device with max speed being UDMA2 (say a cdwriter) and another device with the max speed being UDMA 4/5 (say an ATA 100/133 IDE HDD), the entire channel will run at lower of the two speeds. SATA does not suffer from such eccentricities and SATA2 (is it 300Mbps or 3Gbps, BTW?) at least doubles the theoretical bandwidth.I have never done any benchmarking stuff. Will try hdtune. What I talk about is my perception of things. it is possible that I am seeing what I want to see; I can't deny that fact.
