linux má na blaclistu pouze queued TRIM a původní Trim funguje??
Jsou na to dva různé flagy, záleží tedy model od modelu.
Trim je zcela vypnutý pouze jednou:
{ "SuperSSpeed S238*", NULL, ATA_HORKAGE_NOTRIM, },
Queued TRIM:
{ "Micron_M500_*", NULL, ATA_HORKAGE_NO_NCQ_TRIM | ATA_HORKAGE_ZERO_AFTER_TRIM, },
{ "Crucial_CT*M500*", NULL, ATA_HORKAGE_NO_NCQ_TRIM | ATA_HORKAGE_ZERO_AFTER_TRIM, },
{ "Micron_M5[15]0_*", "MU01", ATA_HORKAGE_NO_NCQ_TRIM | ATA_HORKAGE_ZERO_AFTER_TRIM, },
{ "Crucial_CT*M550*", "MU01", ATA_HORKAGE_NO_NCQ_TRIM | ATA_HORKAGE_ZERO_AFTER_TRIM, },
{ "Crucial_CT*MX100*", "MU01", ATA_HORKAGE_NO_NCQ_TRIM | ATA_HORKAGE_ZERO_AFTER_TRIM, },
{ "Samsung SSD 8*", NULL, ATA_HORKAGE_NO_NCQ_TRIM | ATA_HORKAGE_ZERO_AFTER_TRIM, },
{ "FCCT*M500*", NULL, ATA_HORKAGE_NO_NCQ_TRIM | ATA_HORKAGE_ZERO_AFTER_TRIM, },
Pro zajímanost jsem to sem hodil všechno, nechtěl bych to programovat
