When is OCZ or any other company going to release SATA3 SSDs? Crucial Real SSD is the only oe out for a while now.
 
Real SATA 6Gbps SSDs will come after intel releases its new controller and 25nm NAND flash memory near Christmas this year. Likely others will follow around that date.

I don't think the Crucial can be seen as a real SATA 6Gbps SSD; its more like a SATA 3Gbps controller 'pimped' with a 6Gbps interface, and barely manages to make use of it. A real SSD should be 550MB/s read and 400+ write. That's in line with what i expect from the newer Intels.
 
The market for sata3 drive doesn't really exist yet not to to mention even current one's still need a lot of maturing, if you want 500MB/s+ speed go PCI-E.
 
Yeah AMD's chipset doesn't do SATA 6 Gbps very well, so we need to wait for Intel to fill that gap. SSDs will come near that chipset release.

Are you sure it is that or is it really that there are no devices available that actually can transfer data at over 300MB/s?
 
So, is there any news about 25nm drives in the future? Looks like from what I have read, is that Intel/Micron will be out 1st. Will these drive feature a true SATA3 Interface?
 
Has Intel released a roadmap for 6Gbps support on its motherboard chipsets? I have no doubt they will put it in their next SSD controller, but last I heard they were being quiet about it on the host side.
 
Isn't sandy bridge coming out in Q4 2010 or Q1 2011. No doubt that this will have SATA3 and USB3.
 
I believe that the upcoming Sadnybridge will have 2 SATA 3 ports and no USB 3.
 
AMD 800 series southbridge has 6x SATA/600; but no USB3 as well. Personally i think 2x SATA/600 PLUS USB3 would be much more logical to consumers. USB3 really is noticeable; the effects of SATA/600 are controversial. You may be seeing cheap'n'dirty SSDs which get very high MB/s scores but still are very slow due to crappy IOps performance. Samsung/Toshiba/Jmicron fall into this category. They don't care about IOps performance; high MB/s sequential scores will make these products sellable.
 
Ahh, ok now that you mention it, I remember now that it was USB 3 that Intel seemed to be dragging their feet on, not 6gig SATA.

Yes, in the end you will see SATA 6Gbps and USB3 chips from third parties being integrated on the 'retail' motherboards (i.e. not those shipped to Dell/HP etc). I'm not a huge fan of those. It highers the cost price of the board, wastes real estate and generally its better to just have one package one chip one driver package etc.

SATA 6Gbps won't really change much for speeds, sure benchmarks will tell you that it's faster, but...
1) even if it is so much faster, any copy action would likely involve another disk/storage medium which is much slower; nullifying your benefit
2) true performance lies in IOps as sequential I/O is already quite fast; SATA 6Gbps does give a boost to IOps but nothing spectacular.

Nevertheless, having a chip with modern interfaces is important as it prolongs the economic lifetime of the product, before it becomes obsolete. Having USB3 + SATA 6Gbps may mean you insert a high-performance SATA 6Gbps in four years into this system again, reviving and boosting its overall performance and usability.

Note however, that few people actually 'upgrade' their systems, but do spend a lot of money on thinking about upgrade path. In most cases this might not be the best way to spend your money, but instead look for products at great value and quality bought at the right time. For example, RAM prices now are excessively high in my opinion. I remember 1GB = 10 euro times; now we're close to 2.5 times that for DDR3 and 2.0 times that for DDR2. CPUs are quite affordable now, in the sense that a 'value' class chip already puts out a lot of performance often at little power consumption. If RAM prices were lower, i would love to build a 4x4GB=16GB server, where i think 400 euro total would be a reasonable price for the RAM. But currently, you're looking at 1000 euros for that kind of space. :(
 
At the rate flash memory is moving I'm not sure the new SATA standard will be the norm in 4 years. I could very well be wrong and the drastic increase in speed we have seen form HDD to SSD could just be a honeymoon and now it will all level out. Time will tell. Until there is something drastic I'll stick with my Vertex.Otherwise I think you made some great points.
 
NAND SSDs are just filler 'till PCM drives are developed for consumer use any way :D

(however long that takes... hahaha)
 
Starting to hear some news about upcoming SSD manufacturers new SandForce SF-2000 chipsets and 500MB/s. When do we think these drives will be out?
 
soon. but dont buy them. SF drives have horrible real steady-state performance.

the new ones will probably be even worse

look at this thread, and the results from this test, and this is read only

and this is the current crop, and many are complaining about unsteady performance with these drives, and they are still very new. you will hear more of this as time goes on...

Thanks for the info there... So, it seems like the C300 SATA3 drive is the fastest currently and does not have degrading problem...
I've got an old 74GB SATA 1 Raptor sitting in my new i7 920 4GHz system. I am dying to get a SSD, but trying to wait until the real SATA3 drives hit. Maybe I should just go for the C300 if none are coming out by early next year.
 
They are supposed to be faster, around 500mb/s. The insides of the drives aren't there yet.

They support SATA6 even if they don't saturate the bandwidth and who knows when a drive will hit 500mb/s.

All this from a guy with a Gen1 Raptor? :D

I know, right? I had an old Raptor from my P4 System. Bullt a new system and wanted to wait for SATA3 drives to come out.

SATA6 drives are here...maybe not to your lofty expectations, but they're here.
 
Here's some SATA6 mechanical hard drives and here's a new contender besides the Crucial lineup.

I'm not sure if this will be of any interest to someone who's looking for 500mb/s from a single drive.

You'll probably hafta hold onto the Raptor a little longer. ;)
 
they are using it, they had initially said they were going to go with their own spec, lightpeak, but instead will go with both.
