LSI Implements SAS 12 Gb/s Interface

Well if you believe post #21 (not saying anyone should) and he only meant high I/O scenarios this whole time, then he does have at least a little standing.

It wouldn't hurt if John Doe stated that at the BEGINNING of the thread instead of at the END.

i'm pretty sure he changed his argument as to not look so bad.

Yes SSD will take over, but right now? Not even close, SSD's in enterprise solutions is still quite rare, it is getting in there but SAS HDD's still hold their ground.
The biggest issue with SSD is their number of writes, they would be raped in heavy write environment. And this I say from my own experience.
SCSI/SAS HDD's have no issues working for 5 years 24/7 while getting hammered, now let me see an SSD do that.

Wrong. You should do some research regarding to current flash cell write levels. Especially on those that're true single cell.

Well if you believe post #21 (not saying anyone should) and he only meant high I/O scenarios this whole time, then he does have at least a little standing. Million IOPS systems were comprised of ~750 short stroked 15K hard drives only five years ago. Performance of two full racks now can be had in 4U thanks to SSDs.

It's not a "little standing". The OP was %100 on about high I/O scenarios, so I went on about that. No in no line I said "HDD's aren't used anymore". They obviously ARE still the most used way of storage. Let it be home or enterprise. The thing you said there is the reason to prefer an SSD instead of hundreds of HDD's.

P.S, the guy on drugs needs reading compherension. You know who I'm referring to. But he seems to like banning people.

This arguement was done late at night. That's why I couldn't word it properly at first.

Really can't see why you would have been banned on the EVGA forums

Well I was referring to "I banned the mailman". Now I'm not going to lie. Yes, the other reason I was banned for was attacking people. I got pissed off of their fanboys and sometimes even went as far as insulting and calling names (but that's not the point).

He, as a mod, called me "on drugs" and didn't give credit to anything I said.

You keep talking about research, well then please show me an SS based drive that can last 5 years like I said (And tested!). And please don't just put some theoretical numbers up because we all know real world isn't like that.

Companies wouldn't bother with improving SAS drives if SSD is taking over so much like you are saying. SSD's still have a long way before they enter heavy enterprise environments.

And also how can I be wrong when I experienced it first hand? I guess you like marketing slides more than real life.

Those numbers are according to RW. SLC can write off tens of Gigabytes per-day.

Companies that can afford are moving to PCI-E SSD's and especially I/O drives. You didn't seem to have experienced anything;

Per day? How many per 1-2-3-4 or more years, if they survive that is.

You did exactly what I said you should not, you gave me some theoretical numbers and those are performance numbers. So I'll ask you again, can you give me any numbers after 5 years of constant duty?

I never said they won't move to SSD, they are as we speak but for now only on those areas where you don't need very high reliability.

And who are you to say what have I experienced and what I haven't? And even more funny you link me some marketing crap after that sentence

So just to sum it up, give me real world (Not predictions or theoretical stuff) data about SSD's reliabilty in heavy write environment after a longer period of time.

Anyway, I see that you are just trying to save yourself here so I'll just end it here, my last post.

50 petabytes. Do the math.

It hasn't been 5 years SSD's became a norm. The first line of SSD with Micron controller started coming out in around 2007, and those were plagued with controller issues. That's why some people are still concerned. They have nothing to do with the enterprise SSD's of today.

To think that SAS HDD's are the only reliable option is laughable at best, really. I/O drives have unmatched reliablity, more so than a mechanical disk. Google ZeusIOPS...

very impressive!

I will jump into it, I feel frisky and cocky. You said they "aren't much used anymore", which is incorrect if we are to believe bta's sources, which I think we should.

No, I said, they aren't "much use" anymore. Not used. Under high input/output conditions since SSD's are superior in that case.
