or does it use Ultra DMA 2 (33MBps)?
or does it use Ultra DMA 2 (33MBps)?
66MB/s for both GSA-4120B and GSA-4163B.
Well, the retail box talks about UDMA2, and in my pc with U/ATA100 connector with 80pin cable it doesn’t show up as UDMA4…
The “Burst Rate” tests here.
Which is not possible with ATA/DMA-33.

By the way, IEEE 1394a allows up to 400Mbps which is about 50MB/s. UDMA-33 allows up to 33MB/s. Most IEEE 1394a and USB 2.0 cases use 40/40 UDMA-33 cables. Maybe there are other bottlenecks as well.
Well on the official HP of Hitach LG it says: Interface Type - E-IDE/ATAPI/Ultra DMA33
for the GSA-4120B same goes for 4160B and 4163B. Now im getting a bit confused…
LG Japans Homepage…
It says that the UltraDMA Mode4(66MB/s) on the retail Package is a missprint and that it is UltraDMA Mode2(33.3MB/s)
Or maybe Kenshin got another drive…
Kenshin, have you been able to reach 16x writing with the GSA-5163D or is it more like 12x?
Did you read my GSA-5163D thread?
The LG4120, LG4160, and LG4163 drives all use UDMA-2 NOT UDMA-4
i think thats how UDMA-4 should look like …
Sorry about the windows is in chinese :o …
can some one confirm that LG have UDMA-4…
by the way this is my HDD 60GB seagats
my 4163 is on my second ide cable as master it detects as UDMA 2, and before anyone says second ide sometimes are only UDMA 2 not on this board as I had my pioneer 108 on this cable for while and it sees it as UDMA 4 in bios auto detect and in xp but the 4163 is seen as UDMA 2 in both bios and xp. Could it be firmware related, I wonder?
I don’t even know why my motherboard sees both my 4120B and 4163B as ATA 66 drives. :o
if you see the DVD buner under BIOS as UMDA-4…this could mean that may be its hardware support it but when it goto windows there may be an driver issue that make the drive only limit at UDMA-2???
the picture i just post above is just gone …over bandwidth
this is going to get confusing.
Why should LG officialy say its UDMA-2 when its UDMA4?
Why should they make an announcement and say UDMA-4 on the package is an error and change it to UDMA-2??
Mine is also reported as UDMA-2
With the writing quality and speed that we have all seen, does it really make a difference ?
Maybe there are some problems. Samsung also said there are some driver-specific problems. Unlike most other ODD companies, LG and Samsung sell a lot of computers, notebooks, PDA’s, servers, desktops, etc. on both OEM and retail markets so they are probably more sensitive to minor compatibility problems. From what I heard, they sounded very reluctant to add UDMA-66 support at Samsung. As far as there’s no serious need to do it, they won’t, was my impression. The same about S-ATA. I mean, if compatibility problems aren’t solved, why add UMDA-66 support when even 16x recording does not require 66MB/s bandwidth and there are people who use 40/40 IDE cables for ODDs?
Does Nero CD-Speed “Burst Rate” show possible peak transfer rate correctly? If so, it must be 66MB/s, not 33MB/s, but not always correctly supported.
Kenshin, have you tried different media with Nero CD-DVD Speed ? I tried it on the 4163 with different CD and DVD media and I get different results (sometimes 21 sometimes 25 MB/sec, but always the same with the same media). Obviously, burst rate should not be dependant on the type of media inserted. So I am not sure what I should think of this test …
What does the device manager tell you? The device manager tells me the LG runs at UDMA2, while a PX-716A runs with UDMA4.
Of course, I tried different types of media. I actually ran the “Burst Rate” tests more than 10 times on GSA-5163D alone.
My Device Manager doesn’t show whether an ODD is UDMA2 or UDMA4.
I burned a UDF 2.1 Data DVD using GSA-5163D@4163B A100 and YUDEN000T02 Fusion 4x DVD+R at 8x. Connected to IEEE 1394a.
And scanned the disc in GSA-4120B@4160B A302 connected to the secondary channel of ICH4.
By mistake, I forgot to set the booktype to DVD-ROM.
