[#1] Blogs: 數碼音樂重播專欄 (4) http://www.review33.com/news/news.php?news_id=355 電腦數碼音樂重播專欄 (4) - 高效能電腦與影音的結合 - 德國 Cebit講了幾期 CAS 基本理論知識後,今期停一停來介紹三月德國 Cebit 電腦展其中一部份。現今高階電腦主要都是遊戲世界。Intel 今年卻有一個專為電腦影音而設的 Home Theater Cube. 事緣在本年初的 CES 2011, Intel 高層聽過(還未完成的) Weiss MAN202 作高清音樂檔案的效果後,邀請了 Weiss 到 Cebit Intel 作示範。當然 Weiss MAN202 是使用 Intel 處理器和 SSD 硬碟,自家開發 Linux OS 和 iPad 搖控。 Home Theater Cube 內的高級影音椅聽說每張是 5,500 歐元!! 全套音響組合由11.1 聲道的 B&W 800 系列喇叭,Classe 前後級與 Cardas 線連接。DTS 在 Cebit 首現其 NEO:X™ 11.1 新制式 - 由 7.1 聲道再加上另外 2 隻前面左右遠聲道和 2 隻前面高度喇叭。 Home Theater Cube 內使用 Intel® Atom™ 處理器和單一 SSD NAS Server 來同時播映有 7 個獨立高清影像 (每個大約是 40MBit/s) 和 Weiss MAN202 高清音樂播放。示範重點是高效能電腦及中央網路儲存設備支援多媒體的威力。 中央網路儲存設備: 最高層: 8 個 3TB 硬碟組成 24TB 中央網路儲存。空閒時只使用 4W 電,開動時 50W。這是 NAS 其中一個優點。 第二層: 8 個 125GB SSD 組成 1TB NAS。所有高清影像及音樂檔案都由這一組 NAS 儲存。 第三層: 左面 Weiss MAN202 連接上 NAS 作兩聲道高清音樂播放。右面 3 個多媒體播放器將 NAS 內影像和 DTS NEO:X™ 作為 Ethernet 轉 HDMI 最低層: 電源處理器在下半年度希望在本地可以成立一個這樣的示範。在不久的未來,中央網路儲存將會是家居必備電器。 |

[#4] Blogs: 數碼音樂重播專欄 (4) traditional hard disk has moving parts. the disc rotating and read write head moving in similar fashion like a turntable with tonearm and cartridge. ssd uses solid state non volatile memory chips to hold data. there is no moving parts. it reads and writes faster and generate no noise. |

[#5] Blogs: 數碼音樂重播專欄 (4) But this SSD is placed inside the NAS which is far away from the MAN202. There is simply no advantage of using SSD in this manner |

[#6] Blogs: 數碼音樂重播專欄 (4) whenever there are moving parts there will be noise plus heat. with heat u need to add fan and there will be fan noise. |

[#7] Blogs: 數碼音樂重播專欄 (4) advantage of Use of SSD should be very stable throughout data rate and speed for smooth video playback of HD and 4K format without any dropout of frame, not for audio. |

[#9] Blogs: 數碼音樂重播專欄 (4) Maybe the NAS in the show were fan-less and passively cooled to eliminate all moving parts including cooling fan to reduce noise, as 8 HDD in a NAS need a big and high flow rate to cool, if using Magnetic Platter based HDD. |

[#11] Blogs: 數碼音樂重播專欄 (4) i cannot understand why u need to think. just do it and verify. after that come back here and report to us. the read/write and transfer rates of ssd should be superior than mechanical hhd. similar with data transfer from ram than from hhd. 最後修改時間: 2011-06-06 23:03:58 |

[#16] Blogs: 數碼音樂重播專欄 (4) nas has processor, simplified operating system, memory, raid card, network card similar to a computer. the differences are computer may have operating system cater for other application software rendering management of ram and processor computing differently from a dedicated nas together with unnecessary services such as firewall, auto update etc which eat into memory and processing. |

[#17] Blogs: 數碼音樂重播專欄 (4) """or we can try replace hdd of our pc to ssd and hear the different with our cas system""" yes u may try this but u have to ensure your pc is fanless to reap the benefit of using ssd instead of hdd how to deal with the heat from power supply and processor is a big question. dont forget the reliability issue. 最後修改時間: 2011-06-07 10:19:46 |

[#19] Blogs: 數碼音樂重播專欄 (4) > Whats the benefit of using SSD in NAS? Speed. There are 7 high definition video (each about 40MBit/s) plus MAN202 audio stream playing at the same time. You can treat it as a home of 7 people watching different HiRes streams at the same time. It doesn't really matter what CPU MAN202 is using because it is keep changing and final product will be some additional things we are trying to imply. > Should we apply SLA on all CAS related equipment and Enterprise Storage as well! =) I thought there is commitment under each sales. |

[#20] Blogs: 數碼音樂重播專欄 (4) To be precise, Blu-Ray could reach even higher than 40Mbit/s on some scene. How could 7 people stream over the ordinary HOME network with a router device?? For pure audio source replay, no need to talk about SSD. We should pursuit for the best format - RED Book. If RB is true then what is the real RAW format identically to RB? |
