Anyone Interested In A NEC 6500A & 8790S Review - Page 2

Post 18 was updated/edited.

Now, once again, I need more media. I have some on order and will wait for that. Don't know how long it will take to deliver. Verbatim 4x DVD-RW, 8x DVD+R, and 2.4x DVD+R-DL.

My wallet is shot for the time being.

I'll hold my thoughts regarding KC. It would not be nice to "place it". HeHe

You are all a bunch of plagarists when it comes using relative geographic locations
I had "down under and over easy" almost since joining and it's taken you guys this long to copy me... What? the cold got to your brains or something

Thanks for doing the testing G-Omaha .
I am about to order one of these beasties for my (nearly two) 8890's.

Actually, the drive is not too bad. It is much better than the Toshibas; however, I have not yet found the "sweet spot" regarding the media. Even at 6x and the 8x that I have attined, it is a substantial improvement over the other laptop units. It's just not as fast as the externals. BTW - I would not buy the Pioneer unit that has close specifications... fear that it will not be as good.

Now, are there times that you are really "over easy" and "done through"? HeHe....

HP DVD Plus R was tested. It will only work at 6x. Media ID is CMC MAGE01. This is the same media sold by Memorex only the brand name has changed.

I have completed buring 200 HP DVD+R's and have encounterd 5 coasters. In each instance, there was a mediaerror at the point that the write speed ws to change to the next higher level.

The burner is a good device. HP Media was OK for the price. Was on sale for $19 per 50 pack. Even though it is limited to burn at 6x max, the experience was not too bad.

Keep us updated on the success of burning to DL media. I would love to get this drive if it indeed burns to DL media with relative reliability.

Thanks for the review.

The DL is backordered. They state that it should ship next week.

Would this be the same on an external burner? I'm assuming not...

If the PC is real slow, you MAY see a degradation in the burn speed; however, I have never experienced this for either the internal or external drive. This is for both the high speed 8790S and and lower speed 3360V that I have. The "multi-step" process is associated with the CLVC (I think that's what it's called) formula used by the burner and the media. When you begin, and then at certain points, there is an "OK" encoded on the media to proceed to the next higher speed. To attain the designated speed both the burner and the media must be in sync.

Both observations apply to internal and external drives. Normally the external drives will start at a faster speed; however, this is not always the case (depends on the drive).

I was just curious about the generalization of this issue (the multitasking slowdown) being attributed to working on a laptop. A couple years ago this would be a fair statement, but I would think that todays laptops are good enough in all aspects to not cause performance issues with a DVD burn while multitasking. If there's some internal architectual bottleneck that is inherent to most laptops that causes this, then I was wondering if that design limitation would also effect an external drive.

I know it's anal, but it's not an afront. I'm just asking for my own clarification.

Thanks!

It really boils down to the buffer over-run and buffer-underrun conditions. The DVD devices that are available today are programmed so that they are protected from these conditions. Now if anyone is brave enought to render a video and try cutting a DVD at the same time on a none HT enabled system, there could be a delay for either the attached or external burner. I burn hundreds of DVD's while working on word documents, browsing the web, and a variety of other activities and can not see a difference in the burn rate/time. There is always a few seconds difference burning DVDs even with the same media and an idle machine - or at least that has been my experience.

Now "rendering" an image to be later cut to a DVD will generally be effected by anything else that is running on the machine - laptop or desktop alike whenever there is a resource conflict.

Read this for a more detailed explanation on what is going on. This pertains to both internal and external drives.

Single Layer(4.7GB) write speeds
1x (CLV) = about 58 minutes
2x (CLV) = about 29 minutes
2.4x (CLV) = about 24 minutes
4x (CLV) = about 14.5 minutes
6x (CLV/ZCLV) = about 10-12 minutes
8x (PCAV/ZCLV) = about 8-10 minutes
12x (PCAV/ZCLV) = about 6.5-7.5 minutes
16x (CAV/ZCLV) = about 6-7 minutes

Dual/Double Layer(8.5GB) write speeds
1x CLV = about 105 minutes
2.4x CLV = about 44 minutes
4x CLV = about 27 minutes

Single Layer (4.7GB) read speeds
6x CAV (avg. ~4x) read speed is max 7.93MB/s = ~14 minutes
8x CAV (avg. ~6x) read speed is max 10.57MB/s = ~10 minutes
12x CAV (avg. ~8x) read speed is max 15.85MB/s = ~7 minutes
16x CAV (avg. ~12x) read speed is max 21.13MB/s = ~5 minutes


DVD Write types
CAV = Constant Angular Velocity, the DVD is written at a constantly increasing speed.
CLV = Constant Linear Velocity, the DVD is written at a constant speed.
ZCLV = Zone Constant Linear Velocity, the DVD is divided into zones. After each zone the write speed is increased.
PCAV = Partial Constant Angular Velocity, the DVD is being written at an increasing speed until a certain speed. After this speed it will not increase anymore.

Great info G-Omaha.
Thanks for all the work you have put into this.
NEC should give you a drive for free.
You have probably sold more of these units for them than they could ever do.

Thanks for the compliment.

Did you buy one for your 8809(s) yet?

I think that I might look at some YUDEN media, that is if I can get some for a decent price - I'm cheap.

Having trouble getting companies to ship internationally and use paypal.
Real pain. A friend of mine in NY said she would cross ship for me so I might have to take up her offer.
