Жутко тормозит MBA A1304 - похоже проблема в SSD
Имеется MacBook Air Mid-2009 (C2D 2,13, 2Gb, SSD 128 Gb). Система OS X Mavericks со всеми обновами. Последнее время замечено странное подтупливание практически на любом процессе. При этом Мониторинг системы показывает незначительную нагрузку на процессор (10-40%). Памяти так же свободной хватает. Возникло подозрение на SSD.
Решил промониторить скорость чтения/записи SSD. Использовал Blackmagic Disk Speed Test из AppStore. Результаты повергли в ступор....

DriveDx показывал, что SSD-шке жить еще более 60%.
Так что же ... SSD под замену или еще можно где-то покопать, может не в нем вся причина. Подскажите, пожалуйста.
