小弟分享一下 音樂檔案儲存在 HDD 與 SSD 聽感之分別：

OS: WS 2016 Datacenter GUI + Fidelizer 8.3

Internal SSD vs HDD to store your music.

"I am in dual pc set up highly optimized and until now I had been storing my music on two Samsung 1tb SSD with some expensive pachanko sata cable.

I was needing more space for my music and I ordered a 3tb Toshiba 2’5” hdd that I connected in usb.

I was in for several good surprise. I am using Daphile and you can preload in ram the music played by the server.

I did compare the same file loaded from the SSD and the HDD. Even though it is played from ram , the file loaded from the HDD always sound better.

Then i disconnect the power to the SSD and I got an other nice sq increase.

I then deactivated the sata in the bios and got an other nice sq increase.

I have now a very organic and analogically sound in my system , there is no way back.



Several conclusions , SSD are very noisy and you should definitely not used them in your system.

Eventhough that I had in ram exactly the same file coming from the SSD or the HDD , since the HDD file sounded consistently better , it means that the noise coming from the SSD is somewhat stored also in the ram. "

"That's why it is best to avoid using SSDs powered from the motherboard. It's far better to power internal SSDs from an additional low noise +5V voltage regulator using the +12V rail for it's input, for improved isolation from each other and other sensitive areas via the power supply. Internal SSDs are then able to readily outperform HDDs for SQ..

I use a dual Low noise Voltage regulator PCB with 2 separate +5V outputs via John Linsley Hood designed <4uV noise PSU add-ons.
Unfortunately, this is DIY. "

According to Ed Hsu of Sound Galleries, SSDs emit a noise in the 6GHz range that is very difficult to filter and the faster the SSD, generally the noisier it is.  Based on what I was hearing, I had no reason to doubt what he was saying.

對策應該係好似 romaz 師兄咁樣 Roon Server／Roon Endpoint 兩邊都唔好駁任何 PCIe／SATA／USB drives，用隻手指 boot 起咗 OS 入 RAM 之後就掹咗隻手指，全部 files 放入去有 Wi-Fi 或者 SFP 嘅 NAS 就搞掂。

所以 romaz 師兄嘅路向係 Intel X25-E → eMMC → diskless（即係純 RAM drive），少隻香爐少隻鬼之餘 latency 亦都好很掂。

好

再硏究研究，差不多可定案了

Hi Vhs hing ,

以我在本地CAS server match with diff top notch DACs  的經驗 (from Audio NOTE Six Elements DAC,  Wadax, TrinityDAC,  MSB, dCS, CH Precision,totalDAC ,  Lampizator ,  EmmLabs DAC, NAGRA HD etc..) .  Emile 的saying is NOT totally correct .... ,  我唔認為同價錢有關.  同解碼的內部解碼方式. 關聯比較大.

for most of the R2R DAC,  may be true.  for most of the FPGA one.  depends ,  dCS Vivaldi is depends.  

有些解碼.  唔Best match and find out the best sample rate and fine tune ,  可以好好衰聲的 ..

小弟一定要試聽 Evo Extreme 夾 Totaldac D1-12 Mk II.....小弟估計一定會好掂。

不過，等小弟再攪埋部 DIY Roon Server (Xeon) 先，因為一試左 Evo 及 Totaldac ， 小弟死梗

Flac 16-44 都超靚聲

"Because they are solid state devices, their faster switching results in a much higher level of RF/EMI being injected  back into other areas of the PC via the PSU. These switching artifacts have much faster rise and fall times than with an HDD too, which results in a wider bandwidth noise profile. That is why you need to isolate them from the main PSU as much as possible by further attention to detail in the PSU area, at least with high quality Audio applications.

Incidentally, some HDD Data sheets also show the level and bandwidth of this noise output from the HDD going back into the power supply."

掂呀。樂器分隔度明顯強左，細節聽多左少少，立体感強左。高中低更平衡。

小弟做了幾日的測試，要修正一下。

外加 card 如 Jcat Net Card 及 SATA Card 插在 PCIE x4 或以上 的 slot (直接與 CPU 溝通，避免經過 Motherboard 的 chipset), 聲音有好大提升，分析力提高，好重要是細節多了，音場大了。低頻更實在。

測試時：

1. 裝了 Windows Server 2016 Datacenter GUI 版 及 Roon Core 的 850 EVO SSD 用 Afterdark 的 Clay.X SATA cable 駁 SATA Card （PCIE x4).
2. 儲存音樂檔案的 Ironwolf 10T HDD 用 Pachanko Pure Reference SATA cable 駁 SATA Card (PCIE x4).
3. 將原本儲存在 850 EVO SSD 的 2G 大 的 pagefile.sys 搬去 Ironwolf 10T HDD，並加大至8G.
4. Bios 關掉 CPU 的 pstate, cstate, hyberthreading, turbo mode 等等，令到 CPU 在穏定的最高速運行 (3.2 GHz).
5. 指派 CPU 的 其中一個核心 （例如 CPU 0) 剩係比 Roon 用. 其他 process 或軟件用其他核心。
6. 在 OS 上 開啟 Fiderzier 8.3 (Free 版）及 Process Lasso (Trial 版）
