Theres no difference.

Not even SATAIII SSD's can blow SATAIII bandwith let alone mechanical hard drives.

Happy?

There is as you can see in the link I posted.

Oh by the way, why were you bitching about motherboards? Nobody said anything about motherboards, we were talking about HDD prices, and suddenly you show up.

Wrong.

Latest SATA3 SSD's are doing already 550mbps transfer rates, which is very close to SATA3's maximum of 600mbps. I'm 100% sure every major SSD manufacturer could cap the 600mbps already if they wanted, but what's the point since there's no faster connection available.

That is why OCZ is working on the RevoDrive (plugs into 4x PCIe instead of slow SATA3).

Sata 3 for hard drives may slightly improve performance through burst, but usually what people would see is a newer technology drive difference.

Sata 3 only really benefits the latest ssd drives to any major degree.

So, for what its convenient to you, theres a reason to use SATAIII but for what it isn't, it isn't to use SATAII?
Make your mind up and stop contradicting yourself for the sake of contradicting me.

The difference between SATAII and SATAIII performance on Hard Drives is irrelevant and meaningless as seen on that Benchmark from OC.
The difference between SATAII And SATAIII on SSD's is noticeable if the SSD is SATAIII ready.
However, my point still stands, SATAIII SSD's can't use all of SATAIII bandiwith independently of the reasons for such.

Current revodrives utilize very heavy amounts of RAID0 though. As far as I recall, the upcoming model will use 8 separate 'units'.

You can certainly blow past the SATAIII limits with ease though given sufficient money for the NAND chips.

Oh ffs, get off your high horse. Did you just wake up on the wrong side of the bed or have you not had your morning coffee? Go get some and stop ruining the calm nature of, what frankly is, my thread where I'm asking about some HDDs. Others have answered, you're in here with some unreasonably negative attitude practically attacking everyone. Just back off, quit while you're behind, you've been derailing this thread.

All/most old bigger than 80GB SSDs used internally RAID0, that's why big discs were much faster than slower ones. Not entirely sure if they're still doing that, probably not, just heavily parallelized the RAM chips.

Can see whole SATA standard dying soon unless they shape up and getting limited to the old mechanical discs like PATA is for some DVD drives today, it's way too slow for SSDs really.

For your information, threatening to report someone is against the forum rules so you can be penalised for threatening to report my posts.
Still I dare you.

And by the way, chill down, you seem tense.

Fair enough, either way, stop being so negative or stop posting in my thread, *please*.

Simple.

Oh my, so much hostility in this thread. Calm down now, stop the personal attacks and stay on-topic.

More NAND chips and therefore more NAND channels yes (4 for low capacity, 8 for high capacity is a common division), but the REVOdrive uses multiple controllers - and they in turn have multiple NAND channels

The most notable issue that crops up with the REVOdrive is that this layout renders it incompatible with TRIM, just like when running regular SSDs in RAID.

I would not say dying. Its a solid standard for more traditional drives. But it may actually be something that Thunderbolt/Lightpeak could pick up on.

SSDs themselves also aren't confined to any particular physical shapes; which makes them highly flexible (both for connectivity and mounting purposes). A couple of desktop motherboards with mSATA have popped up within the last month for this very reason.

I just upgraded my entire build up to a Z68 motherboard with a WD Caviar Black 1TB SATA III hard drive and the speed difference is definitely noticeable over my old P45 board with a Samsung Spinpoint F3 SATA II 1TB hard drive.

Picture folders load instantly, there's almost no "stop and wait" with the drive whatsoever, burst extraction of archives is very quick (a 600mb TV show extracts in 2-3 seconds tops where it used to take considerably longer) if the file is under 1GB, and it generally feels like a definite upgrade compared to my old drive.

The Z68 board also has the ability to pair an SSD with a mechanical drive using Intel's Smart Response Technology to increase the access speed of commonly used files, so buying a mechanical drive is far from pointless as some people are insinuating. I haven't tried with an SSD yet (it's the next thing on my purchase list) but by all accounts it's pretty awesome.

Don't think anyones been suggesting mechanical drives are pointless.

They're still far far cheaper per storage unit, available in lower (usable size) prices, and have greater maximum capacities in the consumer market.

SSDs are strong system drives, but are ill suited as storage drives; also because they have a much lower data retention rate than HDDs. (A sector of a SSD that isn't written to for a few years will eventually loose its data and reset)

Sure your speed has increased, but most of that is not due to upgrading to a SATA III drive.

You're talking 2 different CPU architectures and on top of that 2 different drives made by other brands.

Now plug that WD Black into one of your SATA II ports and see if you notice a difference. It's unlikely you will.
