2019年8月末に購入したLenovo ThinkCentre M720qのハードディスクをSSDに交換した。
Amazon.co.jpで12月初旬に購入したCFD販売 CSSD-S6B960CG3VX (CG3VXシリーズ 960GB) 9,295円を利用した。
RAMと同じく、SSDの価格も下落を続けていて、1TBが1万円を切る段階までやってきている。

TRIMコマンドに対応しているのを示している部分を赤で着色した。なお、交換前のHDDもTRIMコマンドをサポートしていたので、システム側から見れば交換前後で何ら変わらないことになる。

パーティション12を、現在の容量
230 GBytes (230×1024×1024×1024/512 = 482344960セクタ)を、
新たな容量 204 GBytes (204×1024×1024×1024/512 = 427819008セクタ) に縮小すれば、
末尾のセクタが 1445445632 + 427819008 = 1873264639 になるので、
1873264639 < 1875385008 となって新しいSSDの最大セクタ数内に収まる。
$ resize2fs /dev/sda12 427819008s Resizing the filesystem on /dev/sda12 to 53477376 (4k) blocks. Begin pass 3 (max = 1840) Scanning inode table XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX The filesystem on /dev/sda12 is now 53477376 (4k) blocks long. $ parted /dev/sda (parted) unit s (parted) resizepart 12 427819008s
resize2fsのメッセージで『53477376 (4k) blocks』は、4K/512B=8 より 53477376 block × 8 = 427819008 sector と指定したセクタ数となっているのが確認できる。
パーティションの縮小は、コマンドラインでの入力に不安がある場合は、gparted のGUIを使うほうが簡単かもしれない。(ただし、セクタ単位での指定が出来ず、縮小後のパーティションサイズをちゃんと計算して「204G」と指定するのがコツ)

あまり意味ないかもしれないが、念の為、未フォーマットの新しいSSDにGPTパーティションテーブルでの初期化を掛けておく。

Ubuntu 18.04でのSSDとしての設定
ドライブがSSDとして認識されているか確認
$ cat /sys/block/sda/queue/rotational 0
IOスケジューラが 最も推奨される none となっていることを確認 ([ ... ] で囲まれているモードが有効)。
選択肢としては「Deadline」「CFQ」「Noop(何もしない)」と、それぞれをマルチスレッドに対応させた「MQ Deadline」「BFQ」がある。
$ cat /sys/block/sda/queue/scheduler
[mq-deadline] none
残念ながら、HDDの時の標準設定のMQ Deadlineのままだが、
"It is worth noting that there is little difference in throughput between the mq-deadline/none/bfq I/O schedulers when using fast multi-queue SSD configurations or fast NVME devices. In these cases it may be preferable to use the 'none' I/O scheduler to reduce CPU overhead. " (Ubuntu wiki : IOSchedulers)
ということなので、わざわざ変更する必要もないか...
次に、TRIMコマンドが自動的に実行されるかの確認をする
fstrim.timer サービスが有効であることを確認 (赤で着色した部分が enable)
$ sudo systemctl list-unit-files | grep trim
fstrim.service static
fstrim.timer enabled
タイマーの間隔を確認 (赤で着色した部分で、1週間毎にタイマーが起動される設定。タイマーの残存時間は、SSDの交換日が2日前だったので、タイマー5日残りは正常に動いている証拠)
$ sudo systemctl status fstrim ● fstrim.service - Discard unused blocks Loaded: loaded (/lib/systemd/system/fstrim.service; static; vendor preset: enabled) Active: inactive (dead) $ sudo systemctl status fstrim.timer ● fstrim.timer - Discard unused blocks once a week Loaded: loaded (/lib/systemd/system/fstrim.timer; enabled; vendor preset: enabled) Active: active (waiting) since Tue 2019-12-31 12:33:40 JST; 33min ago Trigger: Mon 2020-01-06 00:00:00 JST; 5 days left Docs: man:fstrim 12月 31 12:33:40 M720q-Ubuntu1804 systemd[1]: Started Discard unused blocks once a week.
また、この1週間の設定がされている設定ファイルは

実行されたログの確認は、次のコマンドで出るのだが...
$ sudo journalctl -u fstrim -- Logs begin at Tue 2019-12-31 12:33:38 JST, end at Tue 2019-12-31 13:17:57 JST. -- -- No entries --
/var/tmp と /tmp を ramdisk (tmpfs)に置いているので、仮に記録がそこに残るとすれば設定を見直さなければ... (1週間待って様子を確認する)
1週間後の確認 (/var/log/syslogをチェック)
