Where can I get my hands on one of those with nice storage and at a good price?

5 gb will cost around $3500.

OMG !!!!!!!!!!!

I've been "out of the loop" for a while. What ARE SSD drives ??? A form of SCSI ???

I'm pretty sure it's basically using something like RAM as a Harddive. I'm not sure if it's non-volitile memory though, so you may still need to boot off a more standard drive.

If a person can't afford a $185 raptor on a 40k per annum salary then they either need to hire a new accountant or learn how to budget their finances.

Just what IS the average Mean Time Between Failures for a WD "Raptor" ???

Yes, the five year warranty IS nice !

You can still bench loading times, etc. That's the real world stuff that counts. And this is why I emphasize that the MaxLine III can come pretty close and beat the Raptor in some cases when we speak about REAL WORLD performance. Thus, while the Raptor's 10k RPM gives it superior synthetic benches, I bet if you were able to run the MaxLine III at 10k, it would win in an instant.

You didn't get the point at all. You have to understand that the "Real World Performance Bench" like game loading time, file copying tests, are all irrelavent. Why? They defragged their HDD each time they run the tests. An average user either never defragged their HDD or defrag once a year or so. On fragmentated HDD it is access time not transfer rate that counts the performance. It is true that MaxLine has better sequential transfer rates, however when come to "REAL REAL WORLD" performance I think raptor would definite outform it still.

Seriously do you defragment your HDD everytime you install a game?
People just can't bother because it takes time

People have been overlooking the fact that fragmentated HDD hurt performance A LOT. Especially notebook HDD where access time is as slow as snails. Since Raptors are great in their access times thats why people have been saying the system, application loading, seems to be quicker; While benchmarks are not confirming that.
So your point of it being psychological is wrong.

From the official site it is 1,200,000 hours
1 billion hours is about 137 years of continuous usage

When I finally got far enough into the thread I saw that SSD stand for Solid State Drive so yes it sounds like a type of RAM'ish drive, if that makes any sense. I would HOPE it is a non-volitle drive at those prices. To lose your information after every shutdown after spending $3500 for it, lol, NOT !!!!

That would be an interesting thing to know but we will never know will we ???

Raptors are great just wish Western Digital would upgrade them already. I would liked a 36 gig one with newer features like 16 megs, NCQ and sata 300.

Holy Sh*t Batman ! That's a long time. I guess one would really have to be hard on a Raptor for it to fail (barring any defects) ???

The solid state means it is made of semiconductor. But it doesn't meant that it can't be non-volatile. They are speaking Flash memory which is common on memory sticks. The data aren't lost even after power is off. They are also called solid state memory.

SSD is just a bigger memory stick that's all
Since flash memory is so expensive the price of SSDs are astronomical

Thanks you Annihilator, that clears up my confusion !

 

[SGtheArtist]

Yes SSD's would not be used if they dumped the data when the power was off. I heard of some DOS programs that can set aside a portion of your system RAM as a driver letter.

The idea is that you could then install Windows on it an have the performace of a SSD however if the power is turned off the RAM is reset and all data is lost on the RAM.

This is why those programs are not that popular, but only to those absolute geeks.

Yes, and no. 1.2 billion is indeed about 137 years, but it would be absurd to think any precision mechanical device like this could run for 137 years straight. It won't, and that's not what MTBF means. MTBF has little to no meaning for a single drive, it's an estimate of the reliability of a large group of drives. If you had a large group of drives, for every 137 years of on time, you would expect one failure. To apply MTBF to a single drive, you have to understand that MTBF is only valid during the designed service life of the drive, which is 5 years for basically every current drive sold, running at the designed power on hours. So if you replaced your original Raptor 27 times during that 137 year period (every 5 years), you should expect one of those drives to fail. Again, this is a drive manufacturer's prerelease estimate. Actual in field performance could end up being much different.

Just curious. Under what circumstances would a person use an SSD drive? Something like a supercomputer running at MIT? Or some company doing really high-end software development? Engineering firm? I didn?t even know such drives existed so now I?m kinda interested (not to buy, just to know). Thanks.

I'm guessing these don't go on sale very often at CompUSA? :Q

If they're even available from them that is!!

Ah thanks. Didn't know MTBF was defined as that. What a silly and misleading name.

Typical disk drives for personal computers have MTBF ratings of about 500,000 hours. This means that of all the drives tested, one failure occurred every 500,000 hours of testing.

I also found this formula:
Reliability = exp(-Service Time/MTBF)

Reliability for Raptor for 5 years service time = exp(43800/1,200,000) = 0.964
Which means 96.4% Raptor drives would run for 5 years without failing.

No, CompUSA doesn't sell them. Anyway, they are used to for things like DNS and database servers, as well as extremely high-end workstations. Baically, anything that can benefit from insane I/O and massive random access times. If you actually want to buy one, you have to go through special vendors, and it's hard to find them in anything other that large orders.

If you want to know more about SSD's, you can ask ribbon13.

You ever gotten to experience an SSD?

 

[stevem326]

Cool, thanks Tick for that info. SSD drives sound really fascinating and I can't wait to start reading up on them to learn more. I'll never be able to afford one...well, maybe one day...but for now it's just fascinating to think that a HD could actually be that fast.

Amazing...

Yeah. Sure. They are really amazing. It can be hard to find info on them though. And BTW, it's not technically a hd, as a hd refers to something using the gme effect. But anyway...

Linky

 

[stevem326]

Yeh, true. It's more like flash memory instead of a spinning HD platter. I was able to find some pretty decent links by going to Yahoo and just typing in "solid state drives".

Yahoo Search Results

Your link is a lot better though...thanks (great info there).

I think I'll just have to be happy with a 15K SCSI Cheetah from Seagate instead

Welcome. In reality, 15k is good enough for a lot of things. However, SSD's still smoke them.

 

[JBT]

I love the seek time of my raptor my Seagate 7200.7 doesn't compare. The seagate is pretty quick when I am doing fbig reads and writes but the Raptor smokes it in that too.

I personally like the low seek time on these drives its very nice and noticible in every day computing for me.

Definitely. I would imagine an SSD against a 15K would be like a 15K against a 5,400 drive...or maybe worse. If I ever win the lotto it's going to be SSD for me. I'll just use the crappy piece-of-junk 15K Cheetah for storage purposes....bwahahahahaha!

Yeh right....
