Raspberry Pi のSDカードの出っ張りが気に入らない。割りそうで怖い。
SD カード怖い
SDカードは意外と丈夫なので、気をつけておけば問題はないと思うのですが、「気をつける」という一手間が面倒だと思います。
microSD アダプタ
Amazon でmicroSD アダプタが売られているが、高い。
千石通商で５００円（税別）で売られてた。出来はいまいちかもだけどちゃんとセットできればいい。
microSD をどれを選ぶべきか。
MicroSDはそのスペックも進化していて、単純に安いのを買ってあとで痛い目を見るのは勘弁したい。 Class10を買おうとおもってた。。。
class 10 を超える UHS-I 規格があった。
microsd
転送最高速で90MB/s がある。
シーケンシャル・リード 90MB/s もでるのか！ NAS のHDDと変わらない。
レビューを見ると、書き込みも速度出てる模様。
でも、最高速を出すにはUSB-3.0が必要じゃね？
一瞬ポチりそうになったっけど、ちょっと落ち着いて考えた。そもそもこの速度を活かせるのか？
usb
えっと、USB3.0だと余裕だけど、USB2.0だとちょっと活かし切れない。
Raspberry Pi は USB2.0だよね。
RaspberryPiはUSB2.0の一本に２本の端子口が付いているて、LAN-100base もUSB経由だから・・・
MicroSDだけ高速対応でも、USB2.0でWifi/100Base、LAN/100Base、SDカードも共有をしてるはずだから。。。。ちょっといいもの買っても完全に無駄金になりそう。
１６GB/８GBも必要なのか？
Raspberry pi の使用容量を確認してみたところ。
takuya@raspberrypi:~$ df -h ファイルシス サイズ 使用 残り 使用% マウント位置 rootfs 15G 2.7G 12G 19% / /dev/root 15G 2.7G 12G 19% / devtmpfs 239M 0 239M 0% /dev tmpfs 49M 264K 49M 1% /run tmpfs 5.0M 0 5.0M 0% /run/lock tmpfs 98M 0 98M 0% /run/shm /dev/mmcblk0p1 56M 9.5M 47M 17% /boot
結局安さ重視でいくことに
RaspberryPiの書き込み速度に限界を感じてるので、高速MicroSDに惹かれたけれど、正直生かせるはずもないだろうってことだし。NASにするなら、USB3.0対応ルーター買ってdd-wrt突っ込んでHDDつなげたほうがいいわけで。
USB-HDDで起動もできるし
ちょっと調べてた時に見かけた
RaspberryPiはどうせ、NFSマウントかAFP経由で、ネットワークディスクを使うことにすればmicro容量もそんなにいらないはず。。なんで殆ど空っぽでいいやと思うことにする。
bootloader だけ突っ込んだらそれでもういいわけで・・・
ちなみに 東芝製品もなかなか
レビューを見ると速度出てる。

ちなみに、インストール済みパッケージはこんな感じ
dpkg で確認してみたところ、インストールしてるパッケージはこんなもの。
８GB使いきるの結構大変なのかも。
