1.0 out of 5 stars
I received faulty discs (and how you can avoid same), March 20, 2010
This review is from: AmazonBasics 8.5 GB 8x DVD+R DL (50-Pack Spindle) (Electronics)
It's silly to buy any inexpensive rebranded discs. They multi-source and you never know what manufacturer's discs you will receive. The "Amazon Basics" discs I received are UME Disc Ltd. which digitalFAQ.com ranks in the lowest quality category (Jan.2010). Someone else in this thread reported getting Ritek. It's the principle reason why consumer reviews vary so wildly and are not helpful to other consumers. With global marketing, fluxuating wholesale pricing/availability, and warehousing timeframes it's fair to assume that source variability increases as rebrander purchase prices decline.
Stick with the widely available Verbatim(1) or Taiyo Yuden(2). Burnable discs are actually a very crude storage technology(3) with inherent product variability even within a single high-end facility. It's worth minimizing the many points of failure by (trying to) buy from a single known-good manufacturing source (and using a known-good burner). It affects burn success rates, write-ability across many burners, readability across many devices, and media shelf-life(4).

(1) Verbatim's better lines reportedly use only Mitsubishi Chemicals discs. Mitsubishi's proprietary and closely guarded metal AZO dye is considered absolute tops. Verbatim's "Value Series" multi-sources with Ritek & CMC being reported by users. Not so good.
(2) Taiyo Yuden is the only maker who also retails their discs. As of Dec.2009 they're known as JVC/Taiyo Yuden. Manufacturing standards are considered the best with their dye running a close second to Mitsubishi's. The reason to buy TY is you know what you're getting ... counterfeits excepted of course. Buy from reputable sources.
(3) Commercial optical discs the reflective surface is mechanically stamped metal foil which is then sandwiched in plastic. An entirely different technology which is superior at all levels: raw materials, the fab process, ease of quality control, and shelf life (essential limitless). By comparison we're stuck
+ shooting a low-power laser through a rapidly spinning disc
+ using dozens of differently manufactured $25-50 mechanical devices
+ in hopes of achieving consistent melting patterns in varying dye-soaked layers of plastic
+ which are impossible for manufacturers to always get evenly spread on all discs
+ and fabbed by different people in different locations using different proprietary dyes
+ with our different software to control the process
+ then using different devices to read the thing.
And that's why commercial discs are always readable by even the crappiest of hardware whilst the best of burned discs are never readable on even all good hardware. It's kinda amazing burned discs work as well as they do.
(4) Mostly an issue confined to re-writable media. They require crystal-laden inks which breakdown much faster. While there is some variability in write-once ink stability it's far outweighed by realities fully in the control of endusers: moisture & temperature levels & swings. These are what breakdown all materials over time. Plastic and ink are no exception.

Good Solid Media, September 23, 2009
This review is from: AmazonBasics 8.5 GB 8x DVD+R DL (50-Pack Spindle) (Electronics)
Dual Layer DVD's are harder and harder to find. It's almost impossible to find them on sale anywhere. I was excited when Amazon introduced this Baiscs program and included Dual Layer discs in the mix.
The discs do not disappoint. A spindle of 50 arrived in a nice neat cardboard box. The packaging was easy to open, except for destroying the packing slip while opening. The spindle is a 'cake box' type, and it seals up very nicely. The outer shrink wrap is clear plastic. The DVD+R DL you see in the picture is a paper wrapper around the discs inside. Fortunately the DVD+ DL words are printed large and in dark black ink on a silver background on each disc, and the cake box is crystal clear. If this hadn't been the case, it would be extremely difficult to identify which discs are inside (I have spindles of four different single layer manufacturers, and two other dual layers).
The first question I had, do they burn at 8X and do they work? Well a good solid resounding yes they do burn at the published speed. They do work well. They are not a magic silver bullet. I have a DVD player that refuses to play any dual layer discs; I've tried Sony, Verbatim, Memorex, and now Amazon Basics - none work at all on this player. However, the Basics disc does play in players that are happy with dual layer discs.
The critical question everyone should have on their mind - the manufacturer. Pretty simple to fire up DVD Identifier; and voila RicohJPND01, revision 067. That should make everyone fairly happy. They fall exactly in the class of DVD blanks with Sony and Memorex - dual layers (the Sonys I have were moserbaerIndiaMBIG101's), not the first class grouping.
I'm very pleased with these discs. Any time I can find Dual Layer discs for under one dollar each, I'm happy. These fit into a very sweet spot of media quality and price per disc. If you need dual layers, this is a good place to purchase.
September 28, 2009 - Burn number 10, not a single flaw yet. No failures, no disc problems. For the record, my two DVD burners are under 1 year old, with current firmware, and are both manufactured by TSST corportation, Models S203N and S223Q, Samsung burners. Product links for my burners: 20X DVDRW DVD Burner - Black SATA, and Samsung SH-S223Q/BEBS Internal Half Height Supermulti SATA 22X Lightscribe DVD-Writable Drive.

Wonderful, September 25, 2009
This review is from: AmazonBasics 8.5 GB 8x DVD+R DL (50-Pack Spindle) (Electronics)
I ordered a pack to try these out since they are fairly new and there inst a lot of information on them. as stated in another reviwe the media code on these as of this date are Ricoh, which are not great, but there are worse, mine were made in china.
that being said, they worked great, i had no problem burning them in my liteon drive.
re: xbox360 backups, they work, i tested these on a liteon drive and a benq drive, both read these disc wonderfully without a single hitch, i usually burn at 4x, but i burned a 360 backup at 8x just to test and it has been reading perfectly no problems at all.
at this price point i can say i am very happy with this product.
