What is the difference between Different sata

[alanwest09872]

Ok Harddisk are very confusing to me and I just wanna get this all straight.


The links next to shows where I got my data from
1. Sata = 150MBps http://www.wisegeek.com/what-is-esata.htm
2. Sata2 = 300Gbps http://www.wisegeek.com/what-is-esata.htm
3. External USB2.0 = 480mbps
4. Gigabit = 1000mbps (3-6 http://www.lyberty.com/tech/terms/usb.html)
5. Firewire 1394a = 400 mbps Firewire 1394b = 800mbps
6. 100 mbit Ethernet = 100mbps
7. Esata Not sure

Bar with me a bit and if my info is wrong up top please tell me so I can learn how this goes.

Different questions.
1. If a sata2 drive is 300Gbps why does hd tune state its max is 100MBps it doesnt make any sense.
2. If a Network is setup with Gigabit setup (with linksys 160n wireless N router everything hooked up wired though) why is my max transfer rate only 10MBps (either a little higher or lower)
3. What is the Esata Transfter rate.
4. I have read that the sata cables that you buy doesnt matter just buy any one of them. How is that possible if one is designed for 150MBps and one is 300GBps. I dont see how it could be the same. Just like you dont wanna use a usb1.0 cord with a usb 2.0 device.
5. If I wanna add more hdd to my WhS setup can I hook up Esata drives will that slow down my transfer rate or will it be uneffected by them.
6. Each sata2 port on a motherboard can handle 300MBps Now why would they say sata2 HDD are 300Gbps if the max is 300MBps and the intel raid chip max speed is 600MBps.

I have other questions please bare with and Thanks in advance for all your help I really do appreciate it and I am sorry for being such a big pain in the YOU know what lol.

sata-1 is 1.5gbps
sata-2 is 3.0gbps
sata-3 is 6.0gbps

if you had a sata2 bus expander it would take one sata-2 3.0gbs and provide it to many drives - the 3.0gbps limit could in theory be hit with a large # of simulatenous transfers.

sata is half-duplex too.

esata is essentially sata with a nice locking external connector (thats crude but good enough for mostly.

if your drive only puts out 100MBPS and you are getting 10MB/s (bits to bytes) then you are right on target mate.

Wait so if my network is Gigbit thats 100MB/s and the hardrive is 100MB/s then wouldnt the transfer be 100MB/s
See when I look at task manager-Netwoking it states only link speed 100Mbps and Gigabit networking is much faster then that isnt it.

Gigabit internet is = to 100 MB/s which is the same speed as the hardrive so why wouldnt it be 100MB/s instead of 10MB or 100Mbps.

Now Just wanna make sure 100Mbps = 10MB


Ok I just ran everything to check where my speed was at. I used hd tune to get my exact information so I can understand this better.

Ok I have a Gigabit Network Setup = 100MB\s or 1000Mbps
On my Server my hdd runs at 102MB\s (wd cavalier green)
On my Windows 7 pc runs at 155MB\s (veloratptor system)
I just transfered a 1.8GB file from the server to the windows 7 system. My max transfer rate was 13MB\s No where near the max.

So is my math wrong should my network be running like this. Or should it be running much faster.

My Networking involves an
1. Abit ip35-e motherboard it is Gigabit Networking 1000Mbps (WHS)
2. Evga 760 Motherboard. Dual Gigabit Networking 1000Mbps. (Windows 7)
3 linksys router 160n. Everything is hooked up wired though. http://www.linksysbycisco.com/US/en/products/WRT160N

I dont know what the max speed on the router is though.

While running speedtest my results were 28Mbps Download and 2Mbps Upload

To eliminate the router as a bottleneck, use a crossover cable between the systems.

If your system is negotiating the link at 100Mbps, then you'll be limited to 12.5MB/s theoretical, which usually translates to about 10MB/s reality. So your numbers seem to line up.

If you're expecting gigabit speeds and you have all the right hardware for it (both switch and NIC), then you've got a driver, hardware, cabling, or negotiation problem. Start by verifying switch/card settings. Check the cable. Update drivers/firmware if it all looks good.

"Four 10/100 Ethernet ports "
That's your problem right there. You need to purchase a gigabit switch, and uplink it to your router. Make sure that you disable jumbo frames in that case.

 

[alanwest09872]

Not to be a pain but can you point me in the direction of the stuff I need. Sorry just networking isnt my strong point. Its easy to hook up but a pain to setup

 

[alanwest09872]

Ok I did a bit of research after talking to you guys. I own a linksys 160n which is 10/100m. I thought it was 10/100/1000. Now if I were to purchase a Dlink wireless n 10/100/1000 will that increase my data transfer rate?

Also does it have the system needed inside of it to run a server. Its called something like pnup or something like that. I dont remember exactly but will it allow for file sharing and media streaming to a ps3 and xbox 360.

Information on the Dlink DIR-655 http://www.newegg.com/Product/Product.aspx?Item=N82E16833127215

Sorry to be a pain and ask alot of questions but I really want the best setup I can get. And I am hoping with this setup I will be able to get 100Mb transfer rate. I believe 1000Gb/s = 100MB/s right now I am at 100Mbps = 10MB/s

And would (AMC CC5E-B50G 50 ft. Cat 5E Gray Cat 5E 350 MHz UTP Gray Network Cable - OEM) work at hooking up everything at top speed. Or do I need to get crossover cables. Right now I have 3 of those hooked up to my system and thats what has me at the 10/100m

You don't need to replace your wireless N router if you are happy with it. All you need to do is add a Gigabit switch.

This is the "green" version, apparently they no longer sell the older versions, but I have several of their older versions in a metal case and they are quite bulletproof. No problems that I can see.

Also does it have the system needed inside of it to run a server. Its called something like pnup or something like that. I dont remember exactly but will it allow for file sharing and media streaming to a ps3 and xbox 360.

That would be UPnP streaming, or DNLA support (for PS3). Usually, those are supported by the networked storage device that you have that actually stores the data. So these features would be supported by a NAS, not a router.
If you plan on using your PC as a media server, then you can get software that runs on the PC, and supports those two standards. Which router or switch you get wouldn't matter in that case, other than the fact that gigabit would allow you to stream easier.

Either way, any decent Cat 5e or Cat 6 cable should allow you to run gigabit speeds. So that AMC cable you linked to is fine. Do you really need multiple 50-foot runs though? It is pretty cheap, for a 50-footer.

 

[alanwest09872]

So how do I hook it up.

My best guess would be

1. Cable modem --- Eithernet Cable ---> linksys (in Spot)
2. One of the 4 Outputs of The linksys Router --- Eithernet Cable --- > 8 Port Switch
3. 8 Port Switch --- Ethernet Cable ---> TO the Pc.

Would this be correct?

Do I need a crossover cable for anything and what would a crossover cable be used for. I only mention It because someone stated it somewhere in this post. What does a crossover cable do.

Thanks again for the help I know I am asking alot of questions and its very kind of you to take the time to help me out.


EDIT: One more dumb question and I'm done I promise lol. My evga 760 has duel gigabit lan outputs. what are both of them used for. Is there anyway I can take advantage of them. I have an extra cord so I am capable of running to my pc so it isnt going to cost me anything My server pc doesnt have duel gigabit lans only one.

1. Windows 7 pc has 2 gigabit duel lan connection (evga 760) Motherboard type
2. WHS pc has 1 gigabit lan connection (abit Ip35-e) Motherboard type

 

[Elixer]

No, you don't need a crossover cable. You only need those if you are NOT using a switch/hub/router...

For your lan ports, if you are thinking that you can 'share' them, then it isn't as easy as that.
You could set one up to access only LAN, and the other for WAN, but then you will need to set things up and I am not sure you want to go into that.

modem <-> router <-> switch <-> all the PCs
If you want to hook them up via ethernet, then fine. You could also do it wirelessly via a wireless bridge, but you are going to spend more $$$ and it won't be as fast as a gigabit connection.

 

[alanwest09872]

Wait so I dont use eithernet to connect the cable modem router switch and pc togeather. I though thats how yhou did it.


quaote If you want to hook them up via ethernet,

 

[MagnusTheBrewer]

Other folks have addressed possible network issues but, I wanted to comment on the implied differences in speed between the various storage devices. Many folks get this confused. A device with a higher maximum throughput does not mean it's faster than one with a lower maximum throughput.

I'll use a car metaphor to explain. Imagine your computer is a car driving on different highways (different storage devices). Your car has a maximum top speed but the highways all have different speed limits (maximum transfer rates). Now, if your car's maximum speed is higher than the speed limit, the road deteriorates so that your speed can not increase beyond the posted limit.

If you car's maximum speed is less than the posted limit, it doesn't matter how high the speed limit is because you can't ever go that fast.

 

[alanwest09872]

Ya that maks sense my current network is only cabable of running 100Mb/s (slow Highway)
My Network card is capable of running 1000Mb/s (fast car gigabit)

So I need to increase the speed limit of my network and to do so I ordered

http://trendnet.com/products/proddetail.asp?prod=515_TEG-S80G&cat=113 Manufactor

So now my Network speed will be 1000Mb/s
My Network card are all 1000Mb/s

So know I have a fast car and a higher speed limit.

Am I correct in thinking this. This is what you meant right.

I also have all cat 6 cables hooking everything togeather.

..............................................................................................Please Main Question Below This Line................................................................
My last question is about the switch. Will that switch be able to be hooked up to my router.

I tried looking online but I couldnt find anything that said it could be. I am guessing that I just hook the router up to slot 1 on the switch and then use the rest of the slots to hook up my devices. Is that correct. Or can I just get rid of my router all togeather.

So how do I hook it up so I have internet connection and my home network setup.

1. Internet --->Cable Modem---->Router <-----> Switch <-----> All the pc's

Or
2. Internet --->Cable Modem --->Switch <-----> All the pc's.

I am looking to get my best connection possible. To get my max Internet (either 30Mb/s or 30MB/s I cant remeber its really fast though lol best Time warner offers) And I wanna get file transfer speed up to at least 100MB/s instead of the 100Mb/s that I have been running at.

Also I dont see a specified slot for the internet on the switch. Routers always have 5 slots. The first one is used for the cable modem to the router and the other 4 are used for the pc's. Where should I plug the cord that is either coming from the router or the switch.

 

[Elixer]

A switch is a really 'dumb' router.
Like I said before, you want modem <-> router <-> switch <-> all the PCs
The router also should have a firewall built in, so that is a big +, handles DHCP, and all that good stuff. In other words, the router will be the one to assign LAN IPs to all your devices.

 

[alanwest09872]

Ok but where do i plug the router into the switch. The router has a dedicated slot for the cable from the cable modem. The switch on the other hand only has 8 slots all the same. Do I just plug it into number 1?

 

[Elixer]

It doesn't make any difference. Use whatever port on the switch. The job of the switch is basically traffic control.
