Pioneer BD Drive Utility是Pioneer在BDR-S07J附的工具程式
而因為BDR-S07XLB和S07J使用相同韌體，
所以Pioneer BD Driver Utility也可以在S07XLB上面使用。
不過Pioneer BDR-S07XLB並沒有附這個軟體......
有網友提供了Pioneer BD Drive Utility給我(在此感謝他)，
所以我就拿來玩玩看....= =+
Pioneer BD Drive Utility開啟後可以看到預設值
跟BD比較有關的就Advanced Quiet Drive Feature和Optimal Writing Speed Feature
下面就在這兩項作測試
先測測看Advanced Quiet Drive Feature，從預設的Quiet Mode改為Performance Mode
BD-ROM(壓片的單層片)
Performance Mode
Quiet Mode
BD-ROM DL(壓片的雙層片)
Performance Mode
Quiet Mode
BD-R DL
Performance Mode
Quiet Mode
從上面三個測試看來，Performance Mode和Quiet Mode在讀取方面互有勝負，
只有Burst Rate是Performance Mode是都占優勢的.....= =
不過Quiet Mode個人聽起來是比較安靜一點，所以在差距不大的狀況下，還是繼續使用Quiet Mode...
接下來是Optimal Writing Speed Feature，用Verbatim BD-R DL 4X做測試
首先先改成Disc Record Surface Quality Mode On
原本是設定2X寫入，被改成4X寫入....
結果燒出來測試機LiteOn iHBS212讀不到，預設OFF的4X寫入放涼還可以讀取，這次放涼也不能讀取....
(Pioneer BDR-S07XLB/S05XLB都可以正常讀取)

台灣販售的Pioneer BD燒錄機新型機只有閹割過BDXL功能的S07XLT和工業版本的207EBK，
如果要支援BDXL就必須買工業版本(沒有蜂巢靜音設計...等)
詢問過代購以後，發現對岸的Pioneer BDR-S07XLB價格(含運到台灣的運費)和207EBK價位差不多
於是就敗了S07XLB...

繼稍早在美國地區公布新款紅標 (Red)系列硬碟之後，WD也正式在台灣地區公布此系列硬碟產品，同時也進一步宣布未來將統一以藍、綠、黑、紅等系列色系區分旗下硬碟產品特性。

原本用的BD-R DL主要都是Panasonic，
但是近期Panasonic BD-R DL傳說要改由TDK大連廠來代工製作，
因此有找之後使用的BD-R DL產品的打算，
最後選定了在光儲存名聲不錯的Verbatim。
台灣現在販售的10片桶裝包裝
新加坡製
可列印的正面
Pioneer BDR-S05XL支援寫入速度有2X、4X、6X、8X
LiteOn iHBS212僅支援4X寫入
接下來先用Pioneer BDR-S05XL燒錄，LiteOn iHBS212做讀取測試、品質測試
S05 4X寫入曲線
iHBS212讀取曲線
品質測試，第二層的表現比較差
S05 2X寫入，iHBS212讀取曲線
品質測試，看起來比4X寫入好
iHBS212 4X寫入曲線
讀取曲線
品質測試
從品質測試看起來，S05 2X > iHBS212 4X > S05 4X
不過S05 2X寫入品質仍不如Panasonic BD-R DL 4X用S05 2X / iHBS212 4X寫入的品質...
在BD Player讀取方面，朋友2年多前的BD Player在換層點卡了一下，沒有Panasonic BD-R DL S05 2X燒順....
較新的BD Player讀取力比較強，但沒有借到就無法測試了...

原本在用的Microsoft Sidewinder X5有左鍵連點的狀況，RMA給Microsoft後，
Microsoft說Sidewinder X5已經停產，而且現在也沒有for Game的滑鼠.....就說要寄Touch系列的給我
但是，Touch系列的滑鼠不適合拿來玩Game啊~~~~

多方考慮之下，就敗了Logitech G500

　　上次泰國洪水引發的硬盤漲價風波剛剛平息，目前硬盤的市場售價已經逐步跌至災前水平。不過進入6月以後泰國南部又迎來了20年一遇的強降水，持續不斷的暴雨引發洪水，部分地區積水深度達3米，並且洪水越過泰國帕府以北以及程逸地區，導致該地區的鐵路、公路中端。不論影響如何，上游代理又獲得了抬價的機會，至本周硬盤全線價格再創新高。
 

http://www.isuppli.com/Memory-and-Storage/News/Pages/Hard-Disk-Drive-Prices-Not-Expected-to-Return-to-Pre-Flood-Levels-Until-2014.aspx
 
 

Although production of hard disk drives (HDDs) is rapidly recovering from the catastrophic Thailand floods that occurred in October, HDD average selling prices (ASPs) are not expected to decline to pre-disaster levels until 2014, according to an IHS iSuppli Memory & Storage Market Brief report at information and analytics provider IHS (NYSE: IHS).

In the wake of the floods, the ASP for the entire HDD market soared to $66 in the fourth quarter of 2011, up 28 percent from $51 in the third quarter. The ASP held steady at $66 in the first quarter, and is expected to decline marginally to $65 in the second quarter, as presented in the figure below.

Meanwhile, after flooding caused a 29 percent plunge in shipments in the fourth quarter, HDD production is rising and will recover completely by the third quarter.

Shipments rose by 18 percent to 145 million in the first quarter and by 10 percent to 159 million in the second quarter.

In the third quarter, shipments are expected to rise by another 10 percent to 176 million. This will mark the first time in 2012 that shipments will exceed their 2011 quarterly levels, up from 173 million in the third quarter of 2011.

Despite exceeding pre-flood shipment levels in the third quarter, pricing is expected to remain inflated.

“HDD manufacturers now have greater pricing power than they did in 2011, allowing them to keep ASPs steady,” said Fang Zhang, analyst for storage systems at IHS. “With the two mega-mergers between Seagate/Samsung and Western Digital/Hitachi GST, the two top suppliers held 85 percent of HDD market share in the first quarter 2012. This was up from 62 percent in the third quarter of 2011, before the mergers. The concentration of market share has resulted in an oligarchy where the top players can control pricing and are able to keep ASPs at a relatively high level.”

 

Potentates of Pricing
Owing to concerns over HDD availability, an increasing number of PC original equipment manufacturers (OEMs) in the second quarter have signed long-term agreements (LTAs) with HDD makers. These LTAs provide shipment guarantees, but lock in pricing that is approximately 20 percent higher than pre-flood levels.

Even if all the OEMs stop entering into LTAs by the end of 2012, it would take about four quarters with a 6 percent sequential decline in the HDD ASP to reach the pre-flood pricing level. However, given that there have been no consecutive 6 percent sequential quarterly declines during the past three years, the likelihood is remote that this would happen now and that HDD pricing will decline accordingly.

Pricing Particulars
Beyond the supply-side factors, demand-related issues also will contribute to inflated HDD pricing throughout 2012 and 2013.

From local drives for media content, to cloud storage of social media and corporate data, the requirement for large quantities of HDD capacity continues to increase.

Meanwhile, PC sales are also projected to climb in 2012. Growth will be driven by the rising adoption of Intel Corp.’s Ivy Bridge microprocessor, the surging sales of ultrabooks in the second half of the year and the proliferation of Microsoft Corp.’s new Windows 8 operating system.

做為消費級固態硬盤中使用最普遍的主控芯片之一，SandForce SF-2281已經出貨了一年
多，但直到現在才被Intel發現，原來這貨竟然是不能正確支持AES-256硬件加密技術的。
AES-256/128加密一直是SF-2200系列主控及相關固態硬盤的宣傳要點(數據加密密鑰長度
分別為256-bit、128-bit)，但是Intel在對產品質量進行檢驗的時候意外發現，該主控中
存在一個缺陷，導致AES-256加密工作不正常，而且問題出現在硬件級別上，是無法通過
更新固件來解決的，只能等待SandForce推出新版本。
為此，Intel已經更新了SSD 520系列固態硬盤的技術規範，將其中的AES-256加密部分統
統降降為AES-128。
如果你是一位SSD 520用戶，又需要AES-256加密或者覺得“上當了”，Intel貼心地推出
了退貨服務。 2012年7月1日及之前購買的SSD 520可以聯繫Intel全額退款，不過必須在
2012年10月1日前完成請求。

在定期整理資料順便檢查HDD狀況時，
發現了Seagate Barracuda Green 2TB出現了SMART警告，就只好趁還能讀取時把資料COPY出來RMA....
搜尋了一下，入手了現在每元/G較低的Seagate 晶鑽 3TB USB 3.0外接式硬碟
(內接式的都比較貴....Orz 且保固大多數都沒有三年.....)
外盒正面照
標示了支援USB3.0和向下支援2.0
外盒背面照
2012/04/20出廠，在對岸組裝，HDD泰國製
內容物有外接硬碟本體、USB 3.0線、變壓器、變壓器電源接頭
變壓器是對岸製造的，全域電壓輸入，+12V 1.5A輸出
外接硬碟上方照....
正面照，運作時會有綠色燈
背面照，USB 3.0接頭是Powered-B的，那個空出來的孔不知道是做啥用....
下方照，有散熱孔
接下來接上PC，做一些簡單測試
硬碟資訊
值得注意的是使用模式在UDMA Mode4
可以看到HDD健康資訊
HD Tune Pro 5.0標準讀取測試
可以看到速度被限制在UDMA Mode4之下.....= =
ATTO Disk Benchmark
總結一下優缺點
優點
1.便宜
目前台灣算是每元/G最便宜的....
2.操作簡單
連開關都免了，開機只要接上電源後，有接到PC就自動啟動
缺點
1.外殼塑膠製，散熱不是很好.....
如果改用鋁外殼散熱應該會比較好，但是價格應該會上漲吧
2.速度受限
看測試可以知道速度受限在UDMA Mode 4.....= =
總之，我只是拿來堆資料，希望不要掛點....
