which hard drive config is faster?

for an apple powerbook laptop:

which is faster, and how much faster?
internal at 5400rpm, or external 7200rpm using firewire 800 (800mbits/second)?

i dont have any of the stuff- im just trying to learn as much as possible before i purchase the laptop this summer. im trying to figure out if its worth it to get a bigger internal, or to go for the smaller capacity internal, and get an external drive in addition.
 
Hi, I have no real experience with your delimma, but a serial (USB/Firewire etc.) device will probably never come any place near the speed of an internal drive. Jim

The question is why do you need a fast drive? Sure things load a bit faster, but unless you move lots of Gb's frequently it doesn't matter that much IMHO.
 
i dont- but if it is faster, theres no point in spending more $ per GB for the bigger internal drive.

agreed on the wrongness
realize that SATA is also serial, and also that the transfer rates on HDDs (excluding exotic ones like 15K SCSI drives) are quite a bit lower than the 100MB/s provided by FW800.
 
Typically, a laptop hdd ran at 4500 RPM or the newer ones at 5400 RPM with a size of 2.5". External HDD assuming you are using a 3.5, it's probably 7200 RPM. With a firewire interface, the laptop hdd is no match at all! USB interface? It's all theoretical! But a FW will kick ass a USB 2.0 anytime any place! Remember the topic is on a external hdd and a laptop hdd. So don't even mention internal desktop models!
 
A modern External FW800 7200rpm HDD will be faster than any 2.5" laptop drive w/ the possible exception of the HGST 7K60, but the most important factor is that it will be much cheaper and can go up to 400GB in capasity compared to only 60GB for high speed stuff in the laptop.

Well that all depends on how old the 5400 RPM HDD is. Newer Seagate 5400's are almost as fast as a Hitachi 2.5inch 7k60. How old are these drives that you are considering using?

My 7200 rpm 7k250 out perfoms many 8 year old 10,000 rpm HDD's.
 
if you want to load your OS faster, you want a 7200rpm Internal hdd. no contest. good luck booting up from a FireWire drive.
also, make sure you have a cache size of at least 8mb. this helps immensely with speed.

Lol it's not wrong but correct.
Performance of USB2.0 and Firewire 800 CANNOT match the performance of PATA, don't even mention SATA. It is due to the latency in bridge chip from the HDD to firewire/USB

If the HDD has SATA interface, it's bridged to firewire, then no way it's performance is greater than SATA!!

Also booting from an external drive is a pain. You want to carry a separate bulk of HDD whenever you carry a laptop? I am not sure whether it even supports booting from a firewire HDD. Anyway if your applications and majority of data are stored in the external HDD, it wouldn't make a lot of difference if the OS is installed internally.

Firewire800 vs PATA of the same Drive so there's no way 1 5400RPM Drive will beat it...

Bench1

Bench2
 
yeah. I know 5400rpm drives are no match for FireWire / PATA / SATA of a drive which was 7200rpm

I was just saying for same drive speed, performance-wise, SATA>SATA-FireWire>PATA>PATA-FireWire
 
The external 7200RPM drive will be faster.

The benchmarks I've seen show that Firewire 800 enclosures perform basically just like a standard PATA controller inflicting no penalty on drive performance. Mechanically identical SATA, PATA, and Firewire 800 drives will all perform pretty much identically, with the interface playing no role at all.

Why not have the best of both worlds? Hitachi makes a 7200 rpm notebook drive
Standard 7k60

Ruggedized version

The second drive is not a ruggedized version of the first. While shopping for a new laptop drive a while back I researched the difference between those 2 models and came up with nothing, they appear to be exactly the same except that the newer "E" version has a 40GB and 60GB version, while the first version has only a 60GB version. Hitachi does have a couple ruggedized series known as Endurastar, but neither is 7200RPM.

Well I could go with that analysis by theoritical speeds but the OP wanted to know which was faster between a Firewire800 vs 5400internal and you might want to edit your bytes :

as it can on Firewire 800
