Скрипт вывода основных данных по использованию SSD

[rogoznik]

Немного youtube (240p, 320p).

Вот оно и пишет

[demonlibra]

Скоро как год пройдёт. Вспомнил про эту тему и повторил замеры.

[demonlibra]

Добавил расчет теоретического срока жизни диска с поправкой на свободное место.

[djsantehnik]

demonlibra, у меня так

[demonlibra]

У Вас параметр 241 имеет не адекватное значение и не меняется после записи тестовых данных.
Соответственно, сценарий не может определить объем записанный данных.

Покажите вывод команды:

sudo smartctl --all /dev/sda

241 Total_LBAs_Written 3085
Этот параметр должен содержать количество записанный блоков. Умножаем на размер блока (512) и получаем объем записанных данных.

3085 х 512 = 1 579 520
У меня нет идей, что под этой цифрой подразумевает производитель Вашего SSD.
При том, что Вы уже записали минимум 10 Гб и диск был в работе 439 часов (меньше месяца).

У Вас есть предположения?

Как вариант, понаблюдайте за изменением параметра 241, чтобы попытаться понять смысл этого параметра.

Судя по цифрам ситуация та же. Что-то в смарт пишется, только смысл этих значений видимо знает только китайский инженер, зовут которого "Кон Чен Ый".
Что такое 684, поди угадай )

А Kingston?

Так я про него и написал. У Вас на снимке параметр 241 равен 684.
Есть мысли, что эта цифра может означать?

SMART Error Log Version: 1
ATA Error Count: 12 (device log contains only the most recent five errors)
CR = Command Register [HEX]
FR = Features Register [HEX]
SC = Sector Count Register [HEX]
SN = Sector Number Register [HEX]
CL = Cylinder Low Register [HEX]
CH = Cylinder High Register [HEX]
DH = Device/Head Register [HEX]

Powered_Up_Time is measured from power on, and printed as
DDd+hh:mm:SS.sss where DD=days, hh=hours, mm=minutes,
SS=sec, and sss=millisec. It "wraps" after 49.710 days.

Error 12 occurred at disk power-on lifetime: 0 hours (0 days + 0 hours)
When the command that caused the error occurred, the device was active or idle.

After command completion occurred, registers were:

SMART Self-test log structure revision number 1
No self-tests have been logged. [To run self-tests, use: smartctl -t]

Selective Self-tests/Logging not supported

[demonlibra]

Прошу прощения. Не заметил.

Ваш вывод smart содержит "241 Total_LBAs_Written"
Откуда взялось "(ID 241) GB Written from Interface"?

[di_mok]

Действительно ... ХЗ

[demonlibra]

Вот с этим и проблема. У некоторых производителей своё видение.

Как вариант, если Вы не относитесь к своему SSD с особым трепетом, можно указать объем тестовой записи 1024 Мб.
Если значение параметра 241 изменится хотя бы на 1, то сценарий должен будет отработать нормально.

Добавил проверку, чтобы при нулевой разнице в параметре 241 после тестовой записи, отображалось сообщение и сценарий не вываливался в ошибку.

[di_mok]

Кстати, в качестве придирки... А не плохо было бы, если скрипт посмотрит есть ли smartctl, и в случае отсутствия предложит установить smartmontools

[demonlibra]

А не плохо было бы, если скрипт посмотрит есть ли smartctl

Ну чтобы чужой сценарий что-то устанавливал вряд ли многие одобрят. А вот проверку и вывод сообщения, пожалуйста.

Сделано.
