Raptor or SATA II - Page 2

It has been for a long time that I want to see the performance of the raptor, now that I can afford it, would anyone shed some lights on the performance of raptor against a standard SATA II drive?
When it comes to dying quickly nothing can outperform the raptor.
Here's difference between my 160gb 7200rpm sata II and my 80 gb 7200rpm IDE

[root@localhost Jonathan]# hdparm -tT /dev/sda

/dev/sda:
Timing cached reads: 2256 MB in 2.00 seconds = 1128.99 MB/sec
Timing buffered disk reads: 222 MB in 3.02 seconds = 73.62 MB/sec
[root@localhost Jonathan]# hdparm -tT /dev/sdb

/dev/sdb:
Timing cached reads: 2328 MB in 2.00 seconds = 1164.77 MB/sec
Timing buffered disk reads: 170 MB in 3.02 seconds = 56.34 MB/sec

My 40gb maxtor is nearly as fast as that 80gb but too small to be useful so it sits in desk drawer. I have a Western Digital 80 GB ATA 100 that is just a dog in my other system.
You might get 95 or 100 mb/sec out of a raptor but they are risky. You might get 85 mb/sec out of a huge 7200 rpm sata II drive but that has nothing to do with the interface its just that a huge drive packs the data closer and comes off faster. You might get 140 150 out of a 3 250 gb drive raid 5 but as you said its alot of pain for a little bit of gain. If you raid anywhere close to 2 terrabytes you are guaranteed to not have any fault tolerance as it will destroy everything if it tries to rebuild a replaced drive just from error rates.
Solid state drives aren't that fast and the are expensive and small compared to paladium coated frisbee drives. You have to load alot of saved games to get your time back fussing with anything. I got the 160gb sata II cause it gave me 4x dvd burn without the occasional buffer underrun. It gave me about 1 more x on verify speed.
Just don't expect alot of speed from drives.

Now a radeon 4850 or 4870. You can expect alot of speed from that. But a nice 250 to 320 gb hitachi or maxtor would give the game loading a decent boost. You'll notice but you won't go wow.

How much are you looking to spend? G.Skill and OCZ both have some nice, relatively inexpensive SSD's on the market now.

Back on the main topic, for the price of one decent-capacity raptor you can get 2 and a half normal disks. Add in a little more cash and you get three Segae/WD industrial disks which, in RAID0, beat the crap out of any Raptor in terms of speed, capacity and reliability. Just make sure you get the server-grade WDs which have 60months warranty. The other ones aren't worth it over their Segate counterparts.

This will go about 170 kb/sec and hit about 3gb/sec on cache. But needs about 160 buck controller.

No cpu overhead. Uses a powerpc to do the transfering.

I don't think you are going to be beating this even with 2 Velociraptors:



The price of 3 WD640AALS drives is amazing considering the performance. This is also with the onboard 780i controller until I buy a Dell PERC 5/i
can you please test your 640's in X2 raid instead of x3. i'd love to know how fast 2x gets compared with 3.

i'm seriously considering getting 2 x 640's Western Digital Caviar Black.

would appreciate it.

reps waiting.

That's lovely! It's industrial server class hard drive. I wonder if it runs on PC. It needs a controller which means I can't do CrossFire when I get another 3850?

No you can get a pcix x1 controller. It's not industrial it's just scsi. A big gang of them under Serial Attached Scsi would be industrial.

http://www.newegg.com/Product/Produc...82E16816103045

Not a huge card doesn't look like it would interfere with many big video cards unless they had bunch of stuff hanging off backside.

I used scsi II for almost forever. Had a really hot 250mb scsi ii drive and nec 4x scsi II cd-rom. Switched to 4gb maxtor and 24x cdrom after bunch of years even though I lost hard drive speed. The switchover to IDE destroyed scsi's presence in market in weird ways and you couldn't get good high quality cd players any more. If the DVD burner makers would go back to scsi III you could actually burn DVD's 16x instead of just talking about it or paying more for blank disks that say they can do it.

The technical problems are that drives have to go 2.5 inch and go to 9800 rpm and then 14400 rpm. Trying to keep all the processing on the drive instead of the controller is making them burn up even though they are still mysteriously touting decades of mean time between failure.

That drive gets hot, really hot but a little airflow works on it cause it's parallel. That controller gets hot too but still only needs a little bit of airflow. Velociraptors get hot too but even burying them in aluminum doesn't look like it's going very well. I'm beginning to see the same screw up of lets all switch to ATA and then make excuses why 133mhz ata doesn't work and then lets all switch to Sata and then make excuses as to why it won't work.

All those drives under the 15000 rpm section use SAS or SCSI-3. They can't make them straight up sata even though the interface would support that much data because any board on the bottom of the drive that can do it would fry in the attempt. So western digital has to run around and play with SATA fail or we have to all raid a bunch of too cheap drives with junk interfaces or the drive manufacturers have to stop trying to set up a bread and butter drive market that only competes with it's too cheap no profit consumer market.

I was digging through my old stuff and found a spare 68 pin scsi 3 cable from back when i was shoving those things in CAD systems and Novell file servers and I'm thinking about just letting the economy do a number on all the corporations that can afford those and rebelling back into scsi again.

All the board makers are going to put onboard video on everything so you have something to use to browse the internet while your 800 watt quad SLI is sleeping because they want to pull a ghost of S3 past and dig through buckets of messed up chips to find a few that they can throw on a board. They can't afford to do that with low power chip processes because it will be too expensive.

Yes I think it's time to go ahead and finish my build and lock the doors while the collective stupidity that is the computer industry runs amok AGAIN. If that drive is too noisy, I'll buy a 12 foot external cable and mount it in the attic to keep ann frank company. Let's make everybody change everything so it can make pedantic improvements and then go nowhere is getting old. Do I really need all these 7 pin connectors on my motherboard so we can have 1 bit scsi and call it sata.

That's how you judge real world performance? That's about as accurate as the sequential reads I see spammed from HDTach.

For what it's worth, I bought Raptors because members in my guild with Raptors loaded first every single time in EQII. Connection speed should have a major impact, but they loaded first every time.
