Review: Lite-On iHAS422 |
Lite-On was kind enough to send us the iHAS422 for review. In this review we will be seeing how this drive from one the world’s best known electronics manufacturers performs in our tests.
The Lite-On iHAS422 supports 22x DVD±R, 8x/6x DVD+RW/-RW, and 8x DVD+R/DL-R DL writing technology, allowing Double/Dual Layer discs of 8.5GB to be written. The Lite-On iHAS422 also supports DVD-RAM reading and writing at 12x speed, LightScribe direct to disc labelling and SmartErase features.
Company Information
We are sure that most of you know Lite-On already, but for those of you wishing to find out more, you can read about it on the Lite-On website.
Drive Specifications
Packaging
Let’s now take a look at the packaging that the drive is shipped in.
The drive that Lite-On sent was the retail version and, we can see the package and contents below.

What’s inside the box
Now it’s time to take a look at the drive itself and what the drive came shipped with.
Our package was the retail version.

The package contained the Lite-On iHAS422, SATA cable, Silver bezel, software disc, fixing screws and bezel removal tool..
Now let’s take a look at the drive.

Black bezel

Silver bezel
The bezel of the Lite-On iHAS422 is nicely styled. We can also see various logos, an emergency eject hole, single green LED and an eject button.

Drive top

Drive bottom

On the bottom of the drive we found one label and we can see the drive was manufactured in China during September 2008.

On the rear of the drive we can see some unspecified jumpers, an SATA power connector and data connector.
Now let’s head on to the next page where we can take a look at the features of the drive….

Summary: The LightScribe feature of the Lite-On LH-20A1L worked perfectly with the exception of the iHAS422 model number, we assume a glitch in the SureThing labelling software, rather than a problem with the iHAS422. |

Thanks for reporting it.
| ... however, 22x burning speed is no more than a gimmick. The iHAS422 only burned one media at 22x and in my opinion, this is too fast for most 16x rated media. It would be more sensible to change to a fast P-CAV writing strategy, starting the burn at 8x and limit the burning speed to 16x. There would not be a drastic drop in writing performance using this writing strategy and burning quality would for sure be much better. |
Unfortunately, it's all about the perception of speed (i.e. the highest X-number) and not about actual speed when drives are designed and marketed these days. And quality takes a backseat to the X-number.

| On our tested DVD+RW media, writing quality was excellent. |
And DVD-RW is excellent too! 
About the Taiyo Yuden 16x DVD-R (TYG03) result...
| The result is pretty good however, Jitter is high and once again we can see that burning 16x rated media at 22x is asking too much of the media. |
...maybe a partial SmartErase kicks in when burn speed exceeds 16x ?

About the Taiyo Yuden 16x DVD-R (TYG03) result...
With that jitter (18.6% maximum!), I'd personally call that a bad result. I would never accept such a result myself - the poor thing was butchered because of the high burning speed, and I suspect the disc would not be fully readable in a lot of older drives due to the very high jitter. The jitter goes berserk as soon as the burning speed climbs above 16x in that scan. |

Good to see the jitter so low on most of your burns. Hopefully, one day, OHT will burn discs even better than this but currently it appears to make things worse.
I have a question about the jitter HT/OHT relationship. I am very much and amature, so, for give me for not completely understanding what I am looking at in the scans. The answer I seek is probably there, I just don't see it when I look at the scans. Anyways, I'm reading that the jitter becomes a problem when burning speeds exceed 16x. It has been stated above that the problem appears to be a result of having the HT/OHT feature active while burning above 16x. So, I have few questions.
Does HT/OHT being active("on") cause problems at slower burning speeds, say 4x or 8x(4x is where I normally burn a dvd)?
Is the HT/OHT problem a result of the firmware, hardware, or both?
If it is a firmware problem, do you think it will be addressed with future firmware updates or patches?
Thanks for the clearing this up for me!

It's still the first firmware so you should give LiteOn a chance to develop the drive, for the first release it works already good.

With CD-DVD speed no, not yet I think Erik Deppe will implement support for that. That the drive is able to do it shows the Plextor version of IHas322 with Plex Utilities. You will only see the TA jitter TAB when you have a A* series also in your system.

I tried a Maxell disc, and it couldn't read it. Lite-on support was not surprised by that. They said the drive may have some issues with Maxell media. They were surprised by the results with the Verbatim discs, but didn't really have any answers. I could understand poor burn results with specific types of media, but I'm really suprised that it cannot read a disc that was just burned in another drive.

I just purchased two of these, and they are going back. I spend an hour on the phone with Lite-on today, and they did not seem to think my drives were defective. The drives will not burn my current blank Verbatim DVD+R MCC 004 discs. They will not even read them, if I burn them my Pioneer DVR-108. If I insert a blank Verbatim, it takes almost 60 seconds to determine what it is . It gets the media code correct, but it thinks it's a DVD+RW, when it's really a DVD+R. If I insert a Verbatim disc that was already burned, it doesn't even think there is a disc in the drive. Every other drive in my house can read these discs. The Lite-on can read some older MCC 004 discs.

. No problems with Maxell discs. 
Two defective drives (with the same problem) is pretty strange. Have you bought the PATA or SATA version? Which is your hardware configuration and have you installed a virtual drive software?
The main media i currently use for burning dvd's is rated 8x (YUDEN000T02). Do you think burning at this speed with this burner will cause issues? i.e. poor burn quality?
Cheers
It's a technicality and almost on the borderline of complete bullshit.
They should just design a dual laser drive that uses two lasers at the same time burning @ 6x. You'd get an average speed of 12x, which is probably faster than these 22x drives.
Oh well, nice review anyways. Agree with Drage on the jitter result. 18% is absurdly high. A high speed scan on that would show massive PIE and PIF increases.

Another 22x DVD burner, the Lite-On iHAS422. How does it compare to the competition? Read the review and find out. |
