as the title, as far as i know hard disk speed stops you from getting maximum speeds?
7,200RPM Sata
10,000RPM Raptor
10,00RPM Raptor x2 Raid0
what's the potential of them? emm thanks
Ignoring SSD's...
edit / 136MB/s for 10k @ raid0...apperently

Umm, your going to have to go into more detail.. because your asking a question that has a lot of depth and areas behind it.Originally Posted by AnDy
Let me ask you a question, what's the purpose behind the question? Then maybe we can give you more help.

No you are wrong, disk speed has NOTHING to do with transfer speeds.
SATA 1 has speeds of up to 1.5 Gbit/s
SATA 2 has speeds of up to 3 Gbit/s
SATA 3 has speeds of up to 6 Gbit/s
The "disk speed" only determines how fast something will load (aka. the "seek time"). It has nothing to do with the transfer speed.
Umm.. you can't transfer data faster then a disk allows you.. for example. most harddrives transfer at about 18-40mb/s (about average), therefore a hard drive is a limitor and of course that is if your read medium is a hard drive, and as for seek speeds, what seek speeds? any good admin knows how to remove this problem, 2nd, ethernet cables also limit things, for example, a 1gbit connection can only transfer at 125mb/s ish in real time on a standard pci-bus, but on a pci-e bus, you would be looking at 250mb/s ish in real time, and of course the network card does limit things a lot, for example, a card without any "buffer memory" wouldn't be as effective as a card with "buffer memory" purely because it can get the job done quicker with it, then without it you would know this if you studied networking. There are mainly limitations to 'speed', even the type and length of the cable you use limits stuff, theres no point using a stardard patch cable if your connected to a high speed (10-40gbit) network.
May I suggest you read up on networking, maybe buy yourself a Network+/A+ book, it will teach you all you need to know, I would recommend it for any person who wants to setup a solid network/server.
Also, server configrations make a massive difference, but i'm not going to spend the rest of the day explaining that to you, so i suggest you need up on different types of servers and there uses.
Please don't flame someone who has been working with servers for years, and does Actutally have a solid cluster network.

Quoting: Gigabit Ethernet (1000base-X) 1,000 Mbit/s = 116 MB/s
if you have good chipsets and good sata2 disks you can get 100MB/s throughput without any raid.
The number 1 thing that will be slowing down you 1Gbps is, a moron who has no idea of bandwidth, doesnt know the difference between bits and bytes. When ever you have morons talking about tech they dont understand, thats when you have failure and slowdowns in the internets/networks.
Also watch out for ADHD posters, they post random bits of information and and put a question mark at the end. Somehow everyone must dance and firstly find the question then find the answer.
... did you just try and tell a network admin how a hard drive works? Oh no you didn't...
Listen mate, go dunk your head in a toilet to freshen up, then come grab a seat because class is about to start.
Transfer rates are dependent on the connection type of a hard drive. IDE is the slowest, followed by SATA and SATA 2 ect. I have already told you the transfer rates of these in my previous post.
Call yourself a professional but have no idea what the "seek time" is? The seek time is the amount of time it takes the physical disk within the hard drive to spin 360 degrees (ie. the maximum time it will take the hard drive to locate any piece of data). It has nothing to do with transferring any data of any sort, it is simply locating the data. The only difference between a regular 7,200rpm HDD and a 10,000rpm raptor? The seek time. Please please please tell me that you knew that.
Btw, did you just claim that a pci-e NIC can transfer at 250mb/s? that is quite impressive considering the fastest speed a physical gigabit Ethernet connection can transfer at is roughly 120mb/s.
You have NO idea what you are talking about, and all your "facts and figures" are all wrong. Typical hard drive transfer speed is 18-40mb/s? That's strange, cos i am getting about 70-80mb/s when transferring files over a gigabit ethernet connection to another PC.
Honestly, how do you turn on your PC in the morning?
lol.. i know what i am talking about, i'm studying at degree level and this is common place. The reason you could have been able to transfer at the speed, is purely because of how the computer uses ram. I'm not going to get into a flamming match with you because i don't think your worth it..
All i am trying to say, is that there are many limitors to transfer speeds when you take into account other parts of the computer.
I am talking about real-time transfer, not the stuff on the title. And for your informaton, Ethernet cables come in many types and sizes, some allow you to transfer data at massive rates, others dont.
I will write up a guide, using references etc, when i get a spare chance to prove my point.

You are studying this, i already have qualifications doing this. No, do not waste your time writing anything up, you have proved your knowledge here quite enough.
You have proved here enough that you can not even grasp the simple concept of bits and bytes, which is why your facts and figures are all wrong.
