裸族＋穀物＋火縄＋キャビア
Mac Pro のオンボードから Newer Technology eSATA Extender Cable で拡張した eSATA はホットスワップできないのでやっぱり不便だった…。なので FireWire800 も使える 裸族のお立ち台 スーパーコンボ を導入。秋葉館の FireWire Toaster と同等品と思われるが、Amazon で裸族買った方が安かったので…。名前がアレだが、箱を捨てれば見た目は同じ。さっそく Xbench してみる。
試したハードディスクは 3.5inch 1TB(333GBx3) 7200rpm 32MB Cache の Western Digital Caviar WD1001FALS。ついでに 2.5inch 320GB 7200rpm 16MB Cache の HGST Travelstar HTS723232L9A360 でもテスト。

当たり前だが 800Mbps の FireWire800 より、3.0Gbps の eSATA の方が速い（Travelstar は 1.5Gbps）。普通に使う時は FireWire800 で、もちっとスピードが欲しい時は eSATA にすればいいか。eSATA だと HD 解像度の ProRes422 でも４ストリームとか行けたのでそれなりに実用になる感じ。つーかこれは裸族じゃなくてハードディスクの性能だな。HD 編集が RAID 組まなくてもできるなんてすごい時代だ。
