Need a HDD to get read speeds around 85MB/s

I'm looking to add a fast HHD to an older system (P3 450mhz). it doesnt need to be very large (30G is big enough), but i dont want to spend much (willing to spend $100 or more if needed)

any recomendations?

(in case your wondering why i need 85MB/s, I've got a RAID0 setup and want to be able to transfer files to it at a similar speed across gigabit lan, another RAID system is not an option, it needs to be able to do mulitple reads and writes)

1 year warranty is good enough for me.

thanks!

1 ATA-100 drive will only get max around 35mb/s. If you want similar speed you would need another raid array. Maybe a wd raptor then you would also need a sata card.
A scsi drive plus a scsi controller and stuff. That one would probably cost the most.

I found this Seagate on newegg, they mention 150MB/s. is that just BS?

Edit:They also mention that in needs a poewer supply adapter...

I realize to go SATA i will need a controller card, since it's going to be PCI will it slow me down?

That's what SATA is rated at so far, but most don't come close.

just like ATA 133.

can someone explaine the ATA100 to 133 difference, can i take advantage of 133 in my old box P3 450 mhz, or my new box P4 2.4b (see sig)

what kinda speeds is the seagate capable of?

Your P3 probably only has ATA100

But that shouldn't matter as current hard drives rarely break the 100MB/s mark while bursting data.

Sustained Transfer Rate on current hard drives around the 35-45MB/s area. (The Seagate is in this area)

Seagate has never been the fastest hard drives either. The most quiet, yes, but not the fastest.

If you're looking for a 30G, 40G or so, you should check out the Maxtor DiamondMax 8 single platter drives.

Also, writing is always slower than reading... I think you'll get around 20MB/s writing.

I have ata 133controller built in, and an ata 133 controller card. I cant tell the difference between the ata 133 and ata 100 in real life, I do share a lot of files/music/videos with the other pc's in my house. You would probably be very happy with an ata 100 controller card and an ata 100 8 meg cache hard drive. [the controller card- ata 100, is justifiably cheaper thatn the ata 133].

Or you may find a scsi card/hardrive for close to $100

The difference between ATA100 and ATA133 is the "33" and the alleged speed difference it provides. Real world differences are about nil. ATA133 was essentially created as a marketing tool by Maxtor. Maxtor marketing guys would have you believe ATA133 provides 133 MB/s. Just like they say ATA100 provides 100MB/s. Neither happens. I don't think you will find a single hard drive that gives you the kind of performance you want. And I don't think another RAID array will assure you those speeds either. I don't necessarily blame the interfeces (ATA100/133, SATA150) so much as the hardware. The drives themselves are not really able to give you that much speed. Maybe a nice SCSI drive with 15,000 rpms would give you closer to the speed you want, though not at your listed budget. Maybe not, I don't know, as I never worked with 15k drives before. Nor do I benchmark, so I wouldn't have any idea about the speed anyhow.

Well, considering the budget, I'd just get a nice 80GB 7200RPM 8MB cache drive and just have and your other hard drives will slow down to compensate for the lack in speed.

There is simply no drive that can attain the speed you desire. Even the fastest current drive, the Fujitsu MAS3735, can only attain 78MB/s at the beginning of its media. Only RAID will be able to attain the speed you seek.

That's what SATA is rated at so far, but most don't come close.

just like ATA 133.

It's not BS since a person should know that the 150 figure only specifies the interface speed. What would you prefer? That they should make the interface slower?


another RAID system is not an option, it needs to be able to do mulitple reads and writes
What do you mean? You sound confused about drive technology.

the disk i currently using is 8m 7200, transfering to a pair of those in RAID0.

I really want to up the transfer rates across the netwrok, so i'm setting up a Gigabit lan.

so now the bottle neck is that single drive on my old box, i'd like to get something alot quicker.

Oh and non of the current SATA / IDE drives are capable of reading 85mb/s as a single drive...yet

I think a SCSI U320 2X15k RAID0 would do that. Even 2 Raptors would be stretching to get those speeds,probably not. No matter what, you'll need some controller card.

Gigabit LAN will get no where near 85MB/s on a slow system like a P3 450. You're not going to get more than 50-60MB/s even on highend desktop systems with something better than 32bit/33MHz PCI.

Just a little tid bit on PCI RAID controllers:

PCI bus maxes out 133mbps, 64bit PCI is double that (266mbps), all of your PCI cards share this bandwidth. Most boards that come with RAID still go through the PCI bus so you're using up the same 133mps bandwidth you're board has. If you're board uses the ICH5-R southbridge, it has SATA built-into southbridge (as with you're standard IDE drives) which will not limit the performance of you're drives.


So do the math of the number drives you're gonna get and the max/read speeds combined they'll achieve so you won't run into bandwidth bottlenecks. BTW PCI-Xpress should fix this in the near future.:)

I can get a max transfer rate of 84.somthing with my RAID0 (according to HDtach and Winbench)

I would just like to get somthing closer than the 35-40MB/s that the 7200 IDE gets now
