  "Seagate and Samsung announced that they have entered into a definitive
   agreement under which they will significantly expand and strengthen
   their strategic relationship by further aligning their respective
   ownership, investments and key technologies.  Major elements of
   the agreement include:" (7項目のうち 2項目だけ引用)



*)"Samsung combining its hard disk drive (HDD) operations into Seagate"
*)"A NAND flash memory supply agreement under which Samsung will
 provide Seagate with its market-leading semiconductor products for
 use in Seagate's enterprise solid state drives (SSDs), solid state
 hybrid drives and other products"

これで HDD製造は、Seagate、Western Digitalと東芝だけになりますよね。
Toshibaのちょっと気になるプレスリリース：

"Toshiba Achieves Highest HDD Performance In Benchmark Testing"
 2011/03/28
  http://sdd.toshiba.com/techdocs/Toshiba_Supermicro_Release.pdf

  "Toshiba MBF Series 2.5-Inch Enterprise Drives Deliver Superior
   Performance and Reduced Power Consumption"
最後に
  "* All testing information and chart are from the "SAS2 Performance
   Benchmark Test Report by Supermicro," 01/07/2011."
とありますが、この Test Reportは見つかりませんでした。

Seagateは Oak Ridge研究所との共同研究でスーパーコンピュータを利用
した次世代磁性体 (素材) 研究を進めていました。下記に紹介するのは
2006-8の資料ですが現状はどうでしょうか。

Seagate側共同研究者の Oleg Mryasov博士は現在は University of Alabama
の准教授です。
