DVD+R Double Layer writing speed and compatibility
The Matshita DVD-RAM SW-9585 supports the DVD+R9 DL standard for writing Double Layer discs with a size of 8.5 GB at a writing speed of 4x. We used a Pioneer DVR-109 drive in order to test the readability of the Double Layer discs that were produced in this section.

Ouch! This media definitely has some trouble starting at the layer break and continuing throughout most of the second layer. This is one of our 'older" DVD+R DL discs manufactured by Ritek, so let's try one from a newer batch next.

The MATSHITA DVD-RAM SW-9585 is an average 4x DVD+R DL writer in terms of speed.
Standalone DVD-Player compatibility
We have 3 standalone DVD-Players available to test the DVD+R DL media (Book Type: DVD-ROM).
- Philips DVP-642
- Koss KD-365
- Philips DVD 704
Compatibility results:
| Drive | Philips DVP-642 | Koss KD365 | Philips DVD 704 | Comments |
| Verbatim | OK | OK | OK | No problems. |
| Memorex | OK | OK | OK | No problems. |
| RiData | OK | OK | FAILED | Freezes on second layer. |
| Fujifilm | OK | OK | OK | No problems. |
All tests went well except for the RiDATA DVD+R DL media on the Philips DVD 704 standalone player. Trouble with this RiDATA disc could be expected due to the large amount of PI and PIF errors reported by the Kprobe scan.
DVD+R9 DL Summary: The Hammer Storage MATSHITA DVD-RAM SW-9585 is an excellent DVD+R Double Layer writer and can even write very well to newer Ritek DL discs at a speed of 4x. This drive would be a good choice for Double Layer writing.
Additional note: Unfortunately the current firmware (B101) does not support writing to DVD-R Dual Layer media. It is interesting to read that Panasonic states that DVD-R DL writing support is possible on this page. We do not know whether or not this feature will be supported in a future firmware from Hammer Storage.
Before we round off this review, let us run the drive through some advanced tests at next page…

Looks like overall bad burner to me. I'm not buying something like that, looks like the burn ZCLV is slow too.
Ritek are bad, full stop!
