Plextor PX-LB950UE External 12x Blu-ray Writer Review


浦科特PX-LB950UE 外置12倍速蓝光刻录机评测


英文原文:http://www.pcstats.com/articleview.cfm?articleID=2605                        中文:七郎

PCSTATS began in the fall of 1999 and is now a leading online technology publication which provides in-depth reviews of a broad range of computer hardware.

PCSTATS网站建立于1999年秋,现在,它是科技类在线出版物的领导者,为读者提供关于计算机硬件的各种广泛而深入的评测报告。

 

In recent weeks the talk of the town has been a sleek black external 12x Blu-ray WRITER from the folks at Plextor. The Plextor PX-LB950UE connects via USB 3.0 or eSATA cables and is capable of burning single layer Blu-ray Disk (BD) media at 12x, double layer BD media at 8x and DVD-R media at 16x speeds. In addition, it supports the playback of Blu-ray 3D movie titles.

最近几周,亮黑色的浦科特12倍速外置蓝光光驱引起坊间热议。浦科特PX-LB950UE可通过USB3.0或eSATA数据线连接到电脑。能实现12倍速的单层蓝光刻录,8倍速的双层蓝光刻录以及16倍速的DVD-R刻录。而且,它支持对蓝光3D电影盘片的播放。

The drive packs in a 8MB buffer and supports LightScribe direct media labeling with the appropriate lightscribe media. This full sized external optical drive naturally accommodates DVD authoring in both the + and - formats, as well as reading and writing to DVD-RAM and Dual-Layered DVD-R discs, CD-R and CD-RW formats. Plextor ship the Px-LB950UE with PowerDVD 9 BD Software Suite (Power DVD, Producer, Director, 2Go, Backup, InstantBurn and LabelPrint software) and PlexUtilities.

该驱动器配备了8MB缓存并支持在光雕盘片上直接进行盘标光雕。这个全尺寸的光驱可原生支持以DVD±R为介质的内容编著,也支持读写DVD-RAM、双层DVD-R、CD-R和CD-RW。浦科特随PX-LB950UE附送PowerDVD9 蓝光软件包(包括Power DVD、Producer、Director,2Go,Backup,InstantBurn和LabelPrint等软件)和PlexUtilities软件。

External Blu-ray drives make the prospect of turning a simple computer system into an advanced Home Theatre PC for watching high definition Blu-ray movies quite alluring. With more and more computers sporting HDMI video outputs, it's not as difficult to connect a PC to a wide screen HDTV as it once was either.

外置蓝光驱动器可使单纯的计算机系统变身为可观看高清蓝光电影的家庭影院电脑,这非常具有诱惑力。随着越来越多的电脑支持HDMI输出,将个人电脑连接到宽屏HDTV也再是什么难事。

The bonus to going the Blu-ray writer route, is that BD-R media is even more useful than DVD media for archiving MASSIVE amounts of data, be that digital photographs, audio, movies or what have you. For ~$1.3 a disk, a single layer recordable BD-R disk will hold 25GB of data. Priced a few dollars higher, double layer BD-R media will soak up 50GB of data on one disk!

使用蓝光刻录机的好处:对于海量数据来说,BD-R介质越来越比DVD介质更好用,想想吧,你积攒的那些数码照片、音频、电影……随便什么数据。大约13美元一片的单层BD-R刻录盘片可以装下25GB数据。再加几美元,一片双层BD-R能容纳50GB!

Retailing for about $219 CDN ($220 USD ?140 GBP) (Newegg ), the Plextor PX-LB950UE brings top of the line 12x Blu-ray writing and playback, along with external CD and DVD authoring to modern PC systems. Minimum system requirements call for at least a 3.4GHz Pentium D or higher CPU, USB 3.0 or eSATA ports, minimum 1GB RAM and WinXP SP2. Blu-ray movie playback demands an HDCP compliant videocard and display as is typically the case.

零售价219加拿大元(220美元、140英镑)(新蛋网价格),浦科特PX-LB950UE带来最高12倍速的蓝光刻录和播放体验,只要电脑够新,同时还可胜任外置的CD和DVD编著任务。最低的系统配置至少是3.4GHz 的奔腾D或更高级的处理器,USB3.0或eSATA接口,最低1GB内存和Windows XP SP2以上的操作系统。蓝光电影播放则需要符合HDCP规格的显卡和显示器。

The Plextor PX-LB950UE is essentially an external chassis wrapped around a PX-LB950SA internal optical drive with a custom bridge board to split the drives' native SATA connection into USB 3.0 and eSATA. A small power brick allows this drive to be used outside of a computer chassis as it does not draw power via the USB cable. The entire unit weighs 1.2kg and measures 22 x 16 x 5cm; it fits nicely next to a laptop without taking up much table space.

其实,浦科特PX-LB950UE是在外置光驱盒中集成了PX-LB950SA内置光驱,并使用桥接电路板将原生SATA连接转换为USB3.0和eSATA连接。使用小型变压器单独供电。全部重量为1.2公斤,尺寸为22 x 16 x 5cm,可放置在笔记本电脑旁边,占不了多大地方。

The plastic chassis is finished in a shiny black coating that looks fantastic but gets smeared with fingerprints like no tomorrow. Since this is an external optical drive, chances are you'll be touching it frequently so Plextor kindly include a small micro-fiber cleaning cloth.

塑料外壳上的晶面涂层看起来美轮美奂,要是上面满是指纹就令人懊恼了。因为是外置光驱,频繁手摸接触是不可避免的,所以,浦科特还贴心附送一块超细纤维清洁布。

The only controls on the front of the drive are the eject button, a status LED and manual eject hole for removing stuck disks. Power is supplied by the aforementioned 12V 2A DC power adaptor. The PX-LB950UE connects to the PC via a USB 3.0 (blue) or eSATA cable. USB 3.0 cables are backwards compatible with USB 2.0 ports, but this is not recommended as the data rates for USB 2.0 are far far less than what USB 3.0 will deliver (for any use other than BD media, USB 2 should be fine). A clear plastic stand is supplied if you want to keep it one edge to save desk space.

光驱前面板上只有退片按钮,LED状态显示,用于退出卡住盘片的手动出片孔。电源是之前提到的12伏2安培直流电源适配器。PX-LB950UE可通过USB3.0或eSATA连接到电脑。USB3.0数据线向下兼容USB2.0接口,但不建议采用这种方式连接,因为USB2.0的数据传输率远远低于USB3.0(用于蓝光以外的介质,USB 2足够。)。要节省桌面空间,可用配送的透明的塑料座将光驱立起。

The rear of the Plextor PX-LB950UE features a USB-B 3.0 data port, eSATA data port, DC power jack and power switch. Incidently it's a bit of a tight fit to get the USB and eSATA cables into the slots as the surrounding plastic bezel is a tight fit. Be sure the cables are firmly seated before turning the device on, they will engage without excessive force if the cable overmould is not butting up against the surrounding bezel.

浦科特PX-LB950UE的背面板上有USB3.0数据接口、eSATA数据接口、直流电源插口和电源开关. 由于塑壳边缘配合的缘故,USB和eSATA数据线插入时偶尔会感觉有点儿紧。打开电源前要确认数据线已可靠连接。如果数据线和塑料机壳不相互挤压,无需太用力,就可将数据线插入。

Blu-ray Data Connectivity

蓝光数据连接

Blu-ray is the high capacity successor to DVD and the 'blu' in Blu-ray refers to the wavelength of light emitted from the laser. To be precise, a 405nm blue laser is used which has a shorter wavelength than the traditional 650nm red laser you're no doubt familiar with from the era of the CD. In simple terms, the finer stream of light allows more information to be packed into a the same space, thus data density can be greatly increased.

蓝光(Blu-ray)作为DVD介质更大容量的继承者,其名称中“blu”指的是激光波长,确切的说,使用了比DVD的 650nm波长红色激光的波长更短的405纳米蓝紫激光,而红色激光自CD时代就开始使用了。简单的说,相同的空间内使用更细的光束可装入更多的数据,从而使数据密度显著增加。

The default read rate for Blu-ray media is 4.5 megabytes per second (referred to as 1x speed), so a 12x speed rating for the Plextor PX-LB950UE is equivalent to ~54 megabytes per second of bandwidth! This much bandwidth requires a better connection speed than USB 2.0 can offer, hence we find a USB 3.0 and eSATA data ports at the rear of the Plextor PX-LB950UE external 12x Blu-ray writer.

蓝光介质缺省的读取速率是每秒4.5兆字节(即1倍速),因此PX-LB950UE的12倍速约等于每秒54兆字节的带宽。这么高的带宽当然需要比USB2.0更好的连接方式。因此,我们在浦科特PX-LB950UE外置刻录机的背面板上找到USB3.0和eSATA接口。

So the obvious question is, which is better? USB 3.0 or eSATA?

显而易见,现在的问题是,那个接口更好?USB3.0还是eSATA?

USB 3.0 or eSATA Data Cable?

使用USB3.0数据线还是eSATA数据线?

Only one data cable should be connected to the drive at a time, and depending on your systems capabilities that mean either the USB 3.0 cable or the eSATA cable. Don't connect both at the same time. The eSATA cable is measures 1 meter long so this is ideal for desktop systems, the USB 3.0 cable is a little short (0.5m long) so it seems better suited to notebook/desktop situations.

两种连接方式无法同时使用,而且还要看电脑的兼容性,这意味着要么使用USB3.0,要么使用eSATA。不可同时连接两种数据线。eSATA数据线的长度为1米,适于桌面电脑。而USB3.0数据线有点儿短(只有0.5米长),看起来更适于将笔记本电脑放在桌面上的时候使用。

While you can use either USB 3.0 or eSATA cables to connect the Plextor PX-LB950UE to a computer system, some computers may experience issues with USB 3.0 delivered via third party add-on cards.

虽然可使用USB3.0或eSATA数据线连接浦科特PX-LB950UE到电脑系统,但若是使用第三方USB3.0界面卡进行连接,恐怕会出问题。

In PCSTATS tests we suffered a BD-R write failure in NeroDiscSpeed 5 Write test while the Plextor PX-LB950UE was connected via a cheap NEC-controller-based USB 3.0 add-on PCI Express x1 card. This issue was resolved upon switching to the motherboards' native eSATA port and the remainder of the BD-R disk burned satisfactorily. Another test system with onboard (native) USB 3.0 ran smoothly, so perhaps this was a one off.

在PCSTATS的测试过程中,我们将浦科特PX-LB950UE刻录机连接到基于廉价NEC控制器的USB3.0介面卡的接口上,就遇到了使用NERO DiscSpeed 5无法进行刻录测试的问题。切换到主板自带的eSATA接口后,其余的BD-R盘片刻录都非常令人满意。在另一套测试系统上,使用主板自带的USB3.0接口,运行也很流畅,不过也不排除偶然性因素。

The USB-B 3.0 plug goes into the back of the Plextor PX-LB950UE external drive.

USB 3.0 is marginally faster, but unless your computer has native USB 3.0 this may entail going through some form of PCI Express x1 USB 3.0 add-on card which doesn't appear to be ideal. Let's take a quick look at some problems PCSTATS encountered while testing this product them move along to a full suite of optical drive benchmarks.

USB 3.0速度会更快一点儿,前提是你的主板上带有USB3.0接口,若使用插在主板PCI Express X1插槽上的USB 3.0介面卡进行连接,体验可能不太理想。下面我们先看看PCSTATS在进行光驱全面测试时,在使用这种介面卡时所遇到的一些问题。

Problems During Testing

测试中遇到的问题

Before we get started we need to preface the following test observations by saying it's still quite difficult to find 12x BD-R media in our region so PCSTATS had to wait for the local office supply store to order in Verbatim 25GB 6X BD-R media (Grand & Toy). At $13 a pop to conduct a BD-R Write test, we only took one shot at it.

我们有必要事先说明,本地目前仍然很难买到12X的BD-R盘片。所以我们不得不等待Grand & Toy(加拿大的办公用品供应商)本地办公室为我们订购威宝(Verbatim)25GB 6X的BD-R。进行一个写入测试居然要花费13块美金,所以我们只测试了一次。

Unfortunately, the Plextor PX-LB950UE BD-R failed to complete Nero DiskSpeed 5's CreateDisk Write test when connected via USB 3.0 add-on card as we previously alluded to. Here's what happened, specifically;

不幸的是,装在浦科特PX-LB950UE里的BD-R没能完成NERO DiskSpeed 5创建测试片的写入测试,原因可能你已知道了,是通过USB3.0介面卡进行连接造成的。事情就是这样的,的确是。

After 9278MB of data being written, the PX-LB950UE stopped responding. 37 minutes later what should have taken 15 minutes to burn was stalled.... The drive's blue status LED kept blinking after Nero was closed down and did not respond when the Eject button was pressed. Nero was listed as "running" in Task Manager and the window responded to mouse commands so the Nero program didn't appear to have crashed. The only recourse was to power off the external Plextor PX-LB950UE drive and curse the heavens over the $13 BD-R coaster it spat out...

在写入9278MB后,PX-LB950UE就没有反应了。预计15分钟的烧录任务用了37分钟还未完成…… 关闭Nero后,按驱动器上的退片按钮,没有反应,蓝色LED状态显示灯一直闪烁。打开Windows任务管理器,Nero仍在运行中任务列表里,并未显示该程序崩溃。唯一能做的就是,关掉浦科特外置PX-LB950UE的电源,然后拿着光驱吐出来的价值13美元的BD-R茶杯垫,气的骂娘。

At best, we can tell you peak write speed was 2.78x before data seemed to flatline... but as only 37% of the 25GB of data space was written, this is not an accurate figure.

充其量,我们只能告诉你,最高写输入速度是2.78x,然后数据传输率就像是直线了,而且,只写入了25GB数据空间的37%左右。

A quick test with PlexUtilities v1.3.0 drive diagnostic tool after the failure indicated a memory failure within the PX-LB950UE. Running the test again to confirm these results gave us a 'Pass'. Go figure. We switched over the native eSATA connection coming off the test computer and using ImgBurn, closed the unfinished BD-R session. The remainder of the BD-R was filled with approx. 13GB of data, burnt to the BD-R via an eSATA cable in 20min at a rate of 6x (26,970 KB/s).

测试失败后,使用PlexUtilities v1.3.0驱动器测试工具进行快测,提示PX-LB950UE内存崩溃。再测一次进行确认,测试结果报告“Pass”。猜猜看,怎么回事?我们换用了测试电脑板载的eSATA接口,并使用了ImgBurn关闭未完成的BD-R写入任务。剩下的BD-R空间里,大约刻入了13GB数据,通过eSATA数据线连接,以6x(26970KB/s)刻录,耗时20分钟。

Nero DiskSpeed's BD-R Read test ran without issue and achieved the rated speed for this BD-R media - a peak of 8x read, 6x on average.

Nero DiskSPeed的BD-R读取测试没有问题,达到了该BD-R介质的评测速度:峰值8x、平均值6x。

Blu-ray Movie Playback Fail - '10,000 BC' Movie Goes Unrecognized

蓝光电影播放失败——“史前一万年”电影无法识别

Keep in mind that Blu-ray Movie playback on computers can sometimes be a rather tricky affair due to excessive Copy Protect requirements. Sometimes, for no apparent reason, a Blu-ray DVD movie just won't play in certain optical drives - we've seen this a couple times at PCSTATS. Other times it's a software or firmware issue, Blu-ray movies on the PC are kind of a pain in the ass in this respect.

记住,由于过度的拷贝保护要求,在电脑上播放蓝光电影,有时会非常棘手。有时根本找不到明确的原因,某个蓝光电影光盘就是无法在某种光驱中播放——这种情况在PCSTATS的测试过程中发生过数次。软件或固件有时也会出问题。在PC上播放蓝光电影,有点儿蛋痛。

Such was the case with the Plextor PX-LB950UE; no matter what DVD software we used (Cyberlink Power DVD8/9), no matter what update we tried, now matter that Cyberlink BD Advisor v2.0.4017 gave the test system a pass, no matter that Plextor PlexUtilities scanned the disk and found it Defect free, PCSTATS could not get its official test Blu-ray movie ('10,000 BC') to play in the PX-LB950UE. The drive simply wouldn't recognize the BR movie disk. It had no problems playing DVD movies or recognizing and reading from BD-R media.

浦科特PX-LB950UE就是这种情况,无论使用什么DVD播放软件(Cyberlink PowerDVD8/9),即使进行了软件的更新,即使Cyberlink BD Advisor V2.0.4017报告系统通过了蓝光播放性能测试,即使浦科特的PlexUtilities扫描整整张盘片没有缺陷,PCSTATS就是无法在PX-LB950UE上播放其官方测试用的蓝光电影《史前一万年》。驱动器视乎不能识别这个蓝光电影盘片。(原文BR含义不明,应为BD。 译者注)。播放DVD电影,或对BD-R介质的识别、读取都没有问题。

A quick search of the internet to find a resolution only turned up a lot of people complaining about the inability to play certain Blu-ray movies on their PC, apparently regardless of Blu-ray drive manufacturer or DVD software. Perhaps this is a Digital Rights Management issue relating to Warner Brother movies - we honestly don't have an answer.

立即在互联网上搜索解决方法,只得到一大堆关于某种蓝光电影无法在电脑上播放的抱怨。显然,蓝光驱动器制造商还是DVD播放软件都有问题。也许这是和华纳兄弟电影相关的数字版权管理问题——我们确实没有找到答案。

No firmware was available at the time of this review to update the Plextor PX-LB950UE. The supplied Cyberlink Power DVD9 software was used. No dice. Several hours trying to find a solution, on Plextor's Support Forums and elsewhere, proved fruitless.

进行此次评测时,PX-LB950UE固件没有更新的版本可用。使用的是随机附赠的Cyberlink Power DVD9软件。不成功,在浦科特的支持论坛上和其他地方用了几个小时寻找解决方案,未果。

Firmware Fix?

固件维修?

The Plextor PX-LB950UE PCSTATS received for testing shipped with firmware ver 1.01 according to Nero InfoTool5. In a last ditch 'hail mary' effort to fix the issues and (hopefully) give its Blu-ray playback a proper evaluation, PCSTATS stripped the internal PX-LB950SA optical drive from its external chassis and installed it in a computer via a direct SATA cable connection. Firmware ver 1.06 was downloaded from Plextor's website, but.... because the drive thinks it's a PX-LB950UE we could not proceed with the the firmware update.

根据Nero5软件的报告,PCSTATS收到的浦科特PX-LB950UE刻录机,固件版本是Ver1.01。为了给出关于蓝光播放的正确评估,我们最后决定孤注一掷,PCSTATS将内藏的PX-LB950SA光驱从外壳中取出,装入电脑机箱,用SATA数据线直接连到电脑主板。从浦科特网站上下载PX-LB950SA内置光驱的Ver1.06固件。但是, 驱动程序还是认为那是PX-LB950UE,所以我们无法进行固件升级。

An oversight on the part of Plextor... no firmware is available for the PX-LB950UE at the time of this review, in spite of the fact that both models are the same device, and thus one would assume, would require the same level of firmware updates.

也许是浦科特公司的疏忽…… 此次评测时,没有PX-LB950UE可用的固件更新。尽管事实上两种型号是同一种设备,如果其中一个型号有更新,那么另一个也应有同级别的固件更新才对。

DiskSpeed 4 is a CD/DVD-ROM benchmark which can test the most important features of an optical drive. In this particular benchmark, we use a pressed CD-ROM with about 640MB of data as the test disk. Using a CD-R or CD-RW as the test disk may impact the results slightly, so pressed CD-ROM media is the standard testing tool.

DiscSpeed 4是CD/DVD-ROM基准测试软件,可用于测试光驱的大部分重要特征。在这个特别的基准测试过程中,我们使用一张内含640MB数据的预录格式CD-ROM作为测试盘。使用CD-R或CD-RW作为测试盘会对测试结果产生轻微影响,所以我们采用预录CD-ROM作为标准测试工具。

Nero DiskSpeed 4 is a CD-ROM benchmark which can test the most important features of a CD-ROM drive. In this particular benchmark we use a pressed Audio CD with about 65 minutes of audio on it as the test disk. CDROMs in general have a harder time processing audio data and hence the results can be drastically slower than equivalent 'pure' data tests.

此番测试我们选用长度为65分钟的音频CD作为测试盘。通常,对于CD-ROM光驱来说,处理音频CD的难度更大,因此测试结果会比相同容量的“纯”数据测试慢很多。

Nero shows us how the Plextor PX-LB950UE stacks up when tasked with reading a BD-R disk. In this test the advertised read speed is 8x, the system achieves that speed.

在BD-R盘片的读取测试中,Nero向我们展示了浦科特PX-LB950UE的能力。广告声称的8x读取速度,在测试中得到了证实。

Easy Blu-ray Writer & Frustrating Blu-ray Movie Playback

方便易用的蓝光刻录机,可惜蓝光电影播放令人沮丧

From a performance standpoint the Plextor PX-LB950UE drive did well for itself by meeting all of its different recordable media speed ratings. There were a few hitches with writing, but PCSTATS is chalking that one up to a cheap USB 3.0 PCIe x1 add-on card. Subsequent BD-R write sessions over eSATA cable ran smoothly.

从性能的立场上看,浦科特PX-LB950UE驱动器在不同可录介质上的表现都不错,有些小故障,不过PCSTATS将其归咎于廉价的的USB 3.0 PCIe x1介面卡。后续通过eSATA数据线连接进行的BD-R刻录环节都很顺利。

BD-R read performance was great. It's important to stress that you'll definitely want a quick computer with a massive amount of hard drive space and plenty of memory if you're thinking about burning BD-R 25GB media. The burning software typically caches all the data to memory before attempting the burn, so drive space is crucial.

BD-R的读取性能优异。如果你要烧录25GB 容量的BD-R介质,无疑需要一台大硬盘、大内存、够快的电脑,这很重要,因为刻录软件一般都会缓存所有要刻录的数据,所以硬盘空间就变得至关重要了。

Since the Plextor PX-LB950UE would not recognize the '10,000 BC' blu-ray movie PCSTATS uses for testing we're a little unsure how to ultimately gauge the Plextor PX-LB950UE 12x external blu-ray writer for Blu-ray movie watching. Plextor's PlexUtilities troubleshooting software was able to scan this Blu-ray movie disk and report back no defects.

由于浦科特PX-LB950UE不能识别PCSTATS用于测试的《史前一万年》蓝光电影光盘,所以我们无法给出浦科特PX-LB950UE 12速外置蓝光刻录机在蓝光电影播放性能方面的最终评价。使用随机的浦科特PlexUtilities故障排除软件扫描这张电影测试盘,报告没有缺陷。

The PX-LB950UE failed to recognize the movie we had on hand yet the Blu-ray disk was not damaged? I suspect a few readers will suggest using this DVD software or that, but in this case the movie didn't show up in Windows Explorer, indicating that the optical drive was the fault point. Why it wouldn't read a Blu-ray movie produced by Warner Brothers is not known.

PX-LB950UE 不能识别我们手上的电影光盘,而且光盘并未损坏?我想有些读者可能建议使用这个或那个DVD播放软件,但是在这个案例中,电影无法在Windows 资源管理器中显示,说明光驱是故障点。为什么它不能读取由华纳兄弟出品的蓝光电影,原因不明。

Retailing for around $220, the Plextor PX-LB950UE is an easy way to add BD-R data archiving to just about any recent PC with an eSATA or USB 3.0 port and plenty of spare hard drive space. Plextor bundles this external Blu-ray reader with the tools to get the job done; Cyberlink's BD suite, as well as is own PlexUtilities software. The software has everything you need to read/write Blu-ray discs, burn CDs and DVDs, as well as a few utilities for creating CD labels.

零售价大约220美元,对于最近购买的有eSATA或USB3.0接口电脑,硬盘空间也足够,那么浦科特PX-LB950UE是获得BD-R数据归档能力的捷径。浦科特为这个外置蓝光光驱配备了完成任务的各种工具:Cyberlink的BD软件包和自行开发的PlexUtilities软件。囊括了用于蓝光读写、CD和DVD刻录,甚至用于创建盘标的几种软件,应有尽有。

By most measures this would be a great external Blu-ray writer, however because the Plextor PX-LB950UE failed to play a commercial Blu-ray movie PCSTATS cannot recommend this drive.

通过多方面考量,这应该算一款极好的外置蓝光刻录机,然而,由于浦科特PX-LB950UE刻录机无法播放一种市场销售的蓝光电影,所以PCSTATS不能对该光驱进行推荐。
