广告误导?读解蓝魔RM600前世今生
当初,在蓝魔RM600在刚推出的时候,蓝魔就大力宣传RM600采用高品质SLC闪存,比其它产品性能更优秀,不少消费者选择这款产品的理由就是因为它采用SLC闪存。

RM600之前的宣传广告
而最近降价的蓝魔RM600,其型号全称是“RM600Le”,只不过某些网站的行情报道标题中依然称其为RM600,某些JS也顺水推舟,把RM600Le依然称作RM600。那么RM600和RM600Le到底有什么区别呢?RM600是蓝魔在去年年末推出的产品,它的其中一个宣传卖点就是采用了高性能SLC闪存。而RM600Le则是蓝魔最近新推的RM600简化版(除非有特别说明,否则通常型号上的Le是代表简化版,大家千万不要理解成是Limited Edition限定版哦),根据一些资料以及我们的拆机证实,RM600Le实际上就是将原版RM600所采用的成本较高SLC闪存芯片换成了较为廉价的MLC闪存芯片。但许多不知情消费者并没有注意这个变化,根本分不清RM600和RM600Le的区别。

RM600Le的传输速度
从价格上来说,采用SLC闪存的RM600 2GB报价是429元,而降价的主角是采用MLC闪存的RM600Le,它2GB报价是399元,差价高达30元。本来,随着3月份闪存芯片价格的反弹,市场上部分MP3产品出现了罕见的升价现象,而绝大部分的产品都开始缺货。正如电脑城里面某经销商说的那样:“现在的MP3,只要有货就容易卖,因为闪存涨价很多MP3厂家都不出货了。”在这个时期,蓝魔RM600降价的消息无疑让不少准备购机的消费者欣喜若狂。但是这种表面上降价,但实际上却换了“芯”的做法,却实在让人难以接受。screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.style.cursor='hand'; this.alt='Click here to open new window\nCTRL+Mouse wheel to zoom in/out';}" ōnclick="if(!this.resized) {return true;} else {window.open('http://www.itime.cn/Article/pic/200703/20070316102900982.jpg');}" alt="" src="http://www.itime.cn/Article/pic/200703/20070316102900982.jpg" ōnload="if(this.width>screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.alt='Click here to open new window\nCTRL+Mouse wheel to zoom in/out';}" border=0>
三星闪存价格走势,在2月底3月初开始反弹
片面夸大!蓝魔的SLC与MLC游戏
大约在两个月前,MLC和SLC之争被炒得沸沸扬扬,几乎随手翻开任何IT类报纸杂志或者登录任何IT类网站,或多或少都会看见关于MLC和SLC相关的文章。某些知名网站上甚至还进行了专题报道,不过细心的读者不难发现,这些专题报道最后舆论导向都是:蓝魔RM600采用了SLC闪存芯片,是高品质的产品。正因为这些文章不断地向消费者灌注一个观点:“SLC才是高品质的闪存芯片”,造成不少消费者都对采用SLC的RM600趋之若骛,而对其它采用MLC的MP3嗤之以鼻。
screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.style.cursor='hand'; this.alt='Click here to open new window\nCTRL+Mouse wheel to zoom in/out';}" ōnclick="if(!this.resized) {return true;} else {window.open('http://www.itime.cn/Article/pic/200703/20070316102900132.jpg');}" alt="" src="http://www.itime.cn/Article/pic/200703/20070316102900132.jpg" ōnload="if(this.width>screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.alt='Click here to open new window\nCTRL+Mouse wheel to zoom in/out';}" border=0>
这样的专题报道,其偏向性非常明显
但认真看下来,专题中也并未能否定MLC闪存,而且还确实承认了MLC闪存是一个大的趋势,只是将MLC和SLC的问题又推回到厂家本身实力上面去了。专题段落节选:然后只从SLC与MLC参数上看,我们并不能只因此而断定视频和音频等设备的好坏。因为对影音类产品来说,使用MLC闪存芯片,必需具备ECC校验机制,主控芯片设计越出色,那MP3的性能也就越高。这其中使用MLC芯片的代表就有:苹果、三星、MPIO等国际品牌的机器。如果主控芯片跟不上MLC的技术要求,那么MCL闪存的出错几率要比SLC高。如去年业界闹的沸沸扬扬的欧洲大批量SD卡招回后国内倾销的风波。
不管MLC缺陷如何,将来MLC肯定会是闪存技术发展的方向之一,对于MLC出现的一些问题,已经出现了例如三星主控芯片,wear leveling,4bit ECC校验等技术解决方案,但这只是相对国外的厂商而言,对于国内品牌总体来说走向完善还需要相当的时间。

专题报道中的SLC和MLC传输速度差距,何来的5-7倍差距?
随着这些专题报道以及相关文章的推出,不少消费者被误导觉得非SLC不买,更有人借此机会去抨击其它采用MLC的产品说是“黑芯”产品。而两个月后今天,蓝魔推出RM600Le,将本来的SLC闪存芯片改为采用MLC闪存芯片,那么小编不禁想问一句,之前说RM600是采用SLC闪存芯片的高品质产品,现在改用MLC闪存后,是否就变成了所谓采用“普通闪存”的低品质产品了呢?澄清:为MLC正名!
实际上MLC和SLC之争本来就不是什么新鲜事,大概在2、3年前就已经有文章详细分析过了,相对于SLC来说,MLC主要有三个缺点:
1、擦写寿命比SLC低,SLC可重复写入次数约10万次,而MLC写入次数则为1万次,寿命理论上存在10倍差距;
2、传输速度要比SLC慢,如没有采用任何优化技术的话,MLC的理论读写速度仅为SLC的1/2-1/3;
3、耗电量比SLC更大,在相同使用条件下SLC比MLC少15%左右的电流消耗。
而MLC的优势在于成本较低,同样的生产工艺,采用MLC技术总是能提高将近一倍的容量,降低1/3左右的成本。换句话说,在容量一路飙升的今天,MLC的优势已经越来越明显,所以包括三星、苹果等国际大品牌在内的绝大部分的MP3厂家都已经转向采用MLC闪存。

上图是苹果iPod Nano 2拆机图,使用编号为HY27UV08AG5M的现代闪存颗粒,经过与现代官方的PDF技术资料对比,确定这是MLC的闪存芯片。
时至今日,随着新技术的应用,MLC的缺点已经逐渐被克服。例如使用耗损均衡技术可以将少部分的频繁读写被分布到了整个存储介质上,从而使得闪存芯片各处的擦写次数趋于一致,减少芯片的局部老化的现象,让寿命获得提升。再者,即使是原来MLC那1万次的擦写次数,假设我们平均每天进行3次擦写,也可以这样一直持续使用至少10年,这个生命周期已经超越了普通MP3产品的生命周期了。传输速度方面,通过采用多块芯片同时工作或者在一片晶元集成更多的读写单位同步运作等方法(大家可以简单理解成和显卡的双通道技术类似),也可以有效提高读写速度。

苹果iPod Nano 2的传输速度,读取速度甚至比采用SLC闪存的RM600快了接近6倍
而随着闪存芯片生产工艺的进步,功耗也在一步步降低。虽然说SLC在功耗上还是占有一定优势,但相比起MP3产品中另外一些如主控芯片、DRAM芯片和音频控制芯片等众多功耗大户来说,MLC比SLC那高出来的功耗对产品整体的影响并不算大。从上面分析不难看出,并不能片面理解成采用MLC闪存的就是“黑芯”产品,而采用SLC闪存的就一定是高品质产品。由于篇幅限制,这里就不再进行深入分析,更详细的资料可以查看:超详细全面透析: 漫步在后SLC时代 这篇文章。
结语:理智看待
其实专题也好,广告也好,换“芯”也好,都是厂家的一些策略,大家不必过激去对待。但是现在的厂家都很精明,所以消费者也必须要精明起来,要看清楚那些含糊其词甚至带有误导成分的灰色地带,面对某些内容片面的广告宣传语也不要轻信,更不被那些错误的舆论所误导。
当然,对于明眼的人来说,这种一开始大肆鼓吹RM600采用SLC闪存,然后突然推出RM600Le改用MLC闪存的行为,也未免有点贻笑大方。
最后,教大家如何分辨RM600和RM600Le版,千万别让JS给忽悠了:1、RM600在包装盒的侧面醒目地贴有“本机内置高性能‘SLC’闪存”的标签,而RM600Le则没有。2、RM600Le的产品正面是有点状的装饰,而RM600的正面则是光亮的屏幕屏。3、RM600Le在包装盒以及机身背部的RM600型号后面都会加上Le的字样,RM600是没有的。
