755 Review (by HWP)

Taiyo Yuden -R 8x (TYG02)
PX-755a, FW 1.02
AS: OFF
Burn speed 12x P-CAV, no slowdown

Very good burn. TA Test says excellent across the disk. My 716 can't do these as well @12x.

Ritek +R 8x (Ritek R03 02)
PX-755a, FW 1.02
AS: On (did create strategy)
Burn speed 8x P-CAV, no slowdown

From a batch of the worst media i ever bought. Here's what the 712 manages to do (the 716 does even worse) for comparison; http://club.cdfreaks.com/showpost.ph...postcount=1527

TA Test says not good to bad. The 755 stopps the Read Test @.7GB position with the same error as it does @ the layer break when scanning a DL disk for Beta/Jitter. In the 716 the Read Test runs the whole disk but shows some problems.

Imation 700MB 32x (CMC Magnetics Co. Type 6)
PX-755a, FW 1.02
Burn speed 48x CAV, slowed to 40x @77min mark

48x seems to have been a bit too much for this 32x media. Powerec kicked in when problems arose. Speedread did not work. Instead of 20-48x only 18-42x was read (but only 17-40x exists by default?)

C1/C2, Beta/Jitter, Read (755) scans:

Imation 700MB 52x (TDK Corporation Type 5)
PX-755a, FW 1.02
Burn speed 48x CAV, slowed to 40x @ about the 68min mark

Speedread did not work. Reading problem towards the end.

I think it's interesting to note that with the 755A and 760A, the recommended speeds for using Mori media are 4x 6x and 8x (with most drives 8x is not recommended).

I got the 755 SATA version on saturday. While I've not got a range of newer media to burn and test I've got over 10 burst tests on Panasonic TYG02 discs (burnt with 755) and i'm getting similar PI's to you on TY media but my PO's are virtually 0 with only none or upto 2 spikes on each scan.

TYG02's burnt on my older NEC 3500 have triple the amount of PI's as the 755 burns.

No issues with the SATA yet despite having nvidia's drivers installed for my mobo. Thanks for the review tho, really makes me want to buy Verbatim Dual layer media now!

Wow hwp, thanks for sharing your results! Excellent work

Here is a scan of a TYG02 (Panasonic) burny on my Plextor 755SA.

I've actually had TY scans that have had 0 red spikes but didn't save them.

This seems to be a pretty good drive I guess i consider buying it. But somehow i want to wait for the 760...

Verbatim -RDL 4x (MKM 01RD30)
PX-755a, FW 1.02
AS: Auto (did not create strategy, AS does not support DL)
Burn speed 6x CLV, no slowdown

Very nice burn concerning PIE/PIF/POE. The 716 with FW 1.09 produces a nicer Beta, also Jitter looks a bit wild on layer 1. However TA Test says very good, very good and good on both layers.

ritek are not the worst disc you can buy, but you can buy better burners for them:
1. scan: px755 1.02@6x AS on (created write strategie - full mode - before)
2. scan: Benq1640 BSLB @12x

Well, sadly Ritek seems to have a great variance in media quality. That is they'll produce any media according to the cost limit a costumer sets them. Never mind if the result is usable or not (at least that is my impression). I still have a remaining stock of older Ritek CD-R that are truly first quality but things have been going down since then IMHO. If we look at http://club.cdfreaks.com/showthread.php?t=84705 (for example) we see lots of bad results and some occasional gems. Now, what good is it if your writer manages somehow to burn them with a good result, when the media start to self-destruct some days or weeks later as show here http://club.cdfreaks.com/showthread.php?t=168559 ?

From my experience Plextor has always had a very extensive media support in their writers. The 716 is a good example IMHO. There is almost nothing that this writer can't burn, albeit you might have to lower the writing speed in some cases. As for the rest that still doesn't work it's my experience that such media are best left alone. There is amost always a good reason why they don't work...

Ritek is too inconsistant from disc to disc to really make a fair test. Personally, I love my Plextor 755-SA. I've not had a Plextor drive since 2000 and this to me seems as good as that one in terms of quality. I'm so glad I made this purchase.

well these scans are from maxell branded riteks, same batch. i can post 5 similar scans from both burners....plex with AS on, auto and off - all extremly bad.

in my opinion plex755 just doesn't like ritek r03.

TDK +RW 4x (RICOHJPN W11 00)
PX-755a, FW 1.02
AS: Auto (did not create strategy, AS does not support RW)
Burn speed 4x CLV, no slowdown

Sony +R 16x (Sony D21 00)
PX-755a, FW 1.02
AS: On (Forced)
Burn speed 16x CAV, no slowdown

In the earlier test of this media (http://club.cdfreaks.com/showpost.ph...12&postcount=7) AS was set to AUTO and did not create a writing strategy. I tried another burn with AS set to "On" and it still failed to create a strategy (same result as in above link). So i went and used 'create strategy (quick)' to create a strategy. A 6x strategy was created. Not what i wanted. I deleted that strategy and used AS with the setting "On (Forced)" to burn this disc. It did create a 16x strategy. It looks like AS has a bit of a 'detection'-problem with these media.

Very good burn IMHO. TA-Test says good, very good, very good. Contrary to the linked burn above, the 716 could read this only with minor problems. The 755 produced a smooth read curve.

Sony +R 8x (Sony D11 00)
PX-755a, FW 1.02
AS: Auto (did create strategy)
Burn speed 8x P-CAV, no slowdown

Good burn IMHO. TA-Test says good, very good, good.

Taiyo Yuden +R 8x (Yuden000 T02 00) as sold by Plextor
PX-755a, FW 1.02
AS: OFF
Burn speed 12x P-CAV, slowdown to 8x approximately between 3.3 and 3.6GB, speeded up again to 12x afterwards.

Very good burn IMHO. Jitter jumps around a bit but TA Test says good, very good, very good. The 712 and 755 read this fine, the 716 has some problems and slows to 2x.

Burst, Sum1, Beta/Jitter, Read (712, 755 and 716) scans:

Hewlet Packard +R 8x (MCC 003 00)
PX-755a, FW 1.02
AS: Auto
Burn speed 8x P-CAV, no slowdown, no 12x overspeed offered (but should be there according to supported media list?)

Very good burn IMHO. Beta has a big jump @ 0.8Gb position but it does not seem to hurt the result. TA Test says good, not good, good (mainly due to big peak shift). Both the 755 and the 716 read this fine.

Burst, Sum1, Beta/Jitter, Read (755 and 716) scans:

Not if it was the first version of MCC003, with a stamper serial ending in X47A.

Heh, right, it's marked "...-X47A"

I've seen the speed drop and then speed back up again on my various 716A drives.

Here you'll find a complete review of a PX-755 with FW 1.02 (czech language): http://www.cdr.cz/a/17017

Taiyo Yuden -R 4x (Yuden TYG01) as sold by Panasonic
PX-755a, FW 1.02
AS: OFF
Burn speed 4x CLV, no slowdown (8x overspeed is not offered)

To compare with an AS burn here: http://club.cdfreaks.com/showpost.ph...7&postcount=23

Better Beta and Jitter than with AS. TA-Test says 'very good' across the whole disc.

Sony 650MB 4x CDRW (Mitsubishi Chemical Type 2)
PX-755a, FW 1.02
Burn speed 4x CLV, no slowdown, full erase done first
Gigarec: 1.1

I don't use 4x CDRW anymore these days. Found this media when cleaning up a drawer. Still the 755 can burn these fine.
