Ответ: Выбираем комп для ла2
Вполне оправдано все. С чего бы это один терабайтный винчестер стал быстрей работать чем пара дисков в рейд массиве?, правда, все же следовало бы помимо двух мелких дисков под рейд (где будет только клиент лодвы) поставить еще один побольше для всего остального.
а с чего это 2 древних винта будут работать пусть и в рейде быстрей чем одноблиновая 500-ка соло?
