Metal platters and silicon wafers are hardly similar, and now that it's possible to make affordable NAND flash drives it'll only get better for the SSD makers in perfect cadence with Moore's Law.Quote:

My 10K Raptor is loud enough. We don't need this. It's a waste of engineering, they should focus on making 7.2K RPM drives as fast as possible before they get phased out by SSD's altogether.
But it's nice to have both, isn't it?Quote:

Totally agree with this. The point I was trying to make with my last post is that i'm already on my 3rd RMA for my Raptor. I have no doubt running @ 10,000 rpm's is a significant factor in the failure rate i have experienced. This time i didn't catch it before it went down and I lost a bunch of data i can't get back. I got lazy and didn't backup. Lesson learned.Quote:

Oddly enough the ol IDE 7200 rpm drives in the family rig keep pluggin away just fine. (knocks on wood)
you totally forgot about mobile right?Quote:

have you seen, any flash device how fast they became larger and cheaper in 2 o 3 years give the market for ssd another 2 or 3 years and you will see more capacity more speed and cheaper prices
2.5" VR 10k Drives are very quiet. In fact I can barely hear them unless they are seeking.Quote:

The 2.5" SAS 15k rpm drives I use (at work) are not extremely loud either, if you ask me WD should have started by slapping a SATAII / NCQ interface on a 15k RPM 2.5" mechanicals and sold that as a stop gap instead of the VR.
6ms access times would have dropped to about 4ms and you'd probably be doing burst reads @ the capped bandwidth of SATAII and sustained not too far behind.
I agree. They are queter and running cooler.Quote:

The few articles I've read about it actually state that SSD's are using more power right now than their HDD couterparts. This may change in the future, but it seems right now the only advantage for mobile users is reliability from being more robust physically.
Also they do generate heat and from this point of view they are quite close to their HDD counterparts (5-8 C less than a Velociraptor if I remember correctly)
the THG article was debunked, most SSD's will run with < 2w
where's the heat coming from?
Yeah sure there's no heat coming from them in fact they run sub-zero :cool:Quote:

Yep, raptors are actually more reliable than most slower drives. If you managed to kill three of them, then it's obviously user error - the failure rates for them are very low and they have 1,000,000 MTBF (which makes 3 failures under normal conditions extremely unlikely).Quote:

hard drives have generally become more reliable and cheaper
but 20,000 RPM needs a lot of R&D for that spindle speed then you have to take in to account reliability then accuracy it is gonna be expensive, with SSD getting cheaper the market is limited for this kind of drives
If your laptop's harddrive is burning hot through the laptop, then your laptop has some serious cooling problems. 2.5" HDDs usually peak at 2.5 watts of power usage, so you can't get more then 2.5 watts of heat out.Quote:

But don't think for a minute that SSD's don't come without a price. The flame that burns twice as bright burns half as long.
I have a 1 74, 2 150's and a 300 now. I've lost one 74 way back when I had a board that didn't lock the bus correctly, so that was my lesson learned. Raptors are very durable, not just fast. If WD could manage to bring 15k or 20k to a 500gb drive I think folks would be stunned at the performance. SSD's will match that capacity eventually, but can you imagine the cost? And the more you scale up the size of SSD's, the more the reliability comes into play. Don't even dream of what a 1-2TB 7200 drive would cost when turned into a SSD version.
Physical HD's have more life in them than they are getting credit for. There will be a changeover for laptops, where cost is already high per MB. But don't overestimate how long it's going to take to get durability perfected, capacities high, and costs down and do all that as physical drives are doing all the same things, lowering cost, increasing capacity and durability and speed.
I honestly like the speed of SSD's so don't take this the wrong way, but if folks are thinking that cost is going to come down by a factor of 50-75% on SSD's in a year or two, you would be wrong on that.
What do you base this on ?Quote:

It not unreasonable to see another reduction of ~50% within 2 years time.
Capacity isnt an issue for the Desktop market is concerned either, once 120-200gb drives become the price the current 32gb ones are then it will take off. You really cant fill up 200-300gb with programs alone, people will buy the SSD's for their OS and all the games/programs then pickup a cheep 1TB normal HD for their random files.Quote:

Not really, 15k RPM Enterprise drives have been around for ages. The first 10,000 RPM drives were in the mid 90s, and I would exactly call enterprise drives unreliable.Quote:

They're good for laptops, but they've got a while before they will have enough speed and capacity for desktop usage.
There can't be no heat even my 2GB Patriot flash drive generates heat (higher than the room temp),also it means that all the review site's who tested the temperature of SSD's are lying.Quote:
