наверное, не очень правильно поставил вопрос. итак, есть веб-сервер, где не очень много записи (база мускула все же и логи), но дофига чтений.
есть ли преимущества в замене именно сейчас достаточно свежего (чуть больше года) винта на какой-то SSD (хранилище все равно на винтах останется)? Или погодить еще годик? Дожить до момента, когда все екнется, не хотелось бы. Смарты пока гоняю...
