But the speed in not guaranteed right? I mean the bandwidth, not all the device can support max speed. And there will be some losses in translating the data with the interface and computer.

Er..sure ? I've never see a device can work 100% with the bandwidth it is capable to support.Got screen shot or not?

erm... i thought SATA2's max speed is 3Gbps (3 Gigabits per sec)??? meaning it's abt 375MB/s (375 Megabyte per sec)

USB2.0's max speed is 480Mbps, meaning it's 60MB/s...

The cable and connector for SATA and SATA2 is the same?

i read in a review that usb is all mroe than enough for to support sata2 data transfer

it is enough by just a bit

on the sata2 and usb, i dun see any difference in file transfer

@ac_N1
It was.

@Ray & astria
Yea.. I think there is no devices which can work with 100% full speed atm. Sure there will some losses right? If USB version of external storage, it depend on the chipset on the casing as well. Some chip can corp with the speed and some cant.

Theoretical i think USB is faster but then the problem on the connector of the devices. That what i can think of.

tried transfering on USB2.0 to my external 2.5" PATA HDD with cha pa lam casing...

max transfer speed i get is 20MB/s only... looks reasonable for USB2.0... since PATA's transfer speed is 100MB/s max...

anyway:

SATA - http://en.wikipedia.org/wiki/Serial_ATA

it is 1.5Gbps for SATA1 and 3.0Gbps for SATA2

USB 2.0 - http://en.wikipedia.org/wiki/USB_2.0#USB_2.0

it is 480Mbps only...

thus for external HDD, their speed is limited by USB severely... unless u use eSATA...

I never really study sata2 This morning see sang_karim is using sata2 only then realise that my board also can run sata2

Ur board only can run SATA. Meaning if u plug in the SATA2 HDD into it, it only run at SATA speed, which is 1.5GB/s.

Eh fylon, didn't notice you also using the same casing as me. Cheap and good.

@pengster
Heheh.. Yea! Got mine for 265! I like the interior! Lol..

@ac_N1
Haha! Migrate than u will get SATA2 + AHCI!

@fylon
stop poisoning me >_<

this device create a lot of problem to ppl who noob with pc special this using acer 4530 ><

Dont know there solve it or not i am interest on this notebook

@ac_N1
Haha.. Mr google will tell u a everything la! Just google! Sometime the explanation is too long! Lazy to type.

@bai1101
Not to this AHCI is bad. Well.. It is because 4350 were running on SATA HDD and actually the hardware in it were create for Vista. But people tend to force XP into it. By right XP do not support AHCI, that is why when people face problem with formatting it. Anyways, just slip stream the SATA driver into your XP installation disc then problem solved. Im currently running on AHCI mode on my rigs in XP. Everything is running fine. Atleast the potential of SATA HDD been unleashed.

@fylon
The reason i din google for it because every explaination comes in essay form @@ Maybe u guys can help me summarize it

Haha.. Dont be lazy man. We do get the info from Mr. Google and digest on ur own.
