یک نمونه NAS
همانند کامپیوترهای خانگی، نوت بوک ها و دیگر تجهیزات محاسباتی، تجهیزات NAS نیز پردازنده و حافظه دارند و هرچه پردازنده قوی تر و سریع تر باشد و حافظه RAM بیشتری در اختیار داشته باشد، کارایی NAS بهتر است. عمده تجهیزات NAS قدرتمند SMB بازار از پردازنده Atom شرکت اینتل استفاده می کنند. یکی از پر قدرت ترین تجهیزات NAS بازار، مدل QNAP TS-659 Pro- 6 Drive Turbo است که از پردازنده ی Dual Core Atom D510 استفاده می کند (شکل 9- 42).
تجهیز NAS مجهز به پردازنده ی Atom گران قیمت هستند و به همین در مدل های NAS خانگی از پردازنده های ARM مانند تراشه های شرکت Marvell استفاده می شود. یک قطعه ی سخت افزاری مهم دیگر در NAS فن یا خنک کننده هاست. هر NAS حداقل دارای یک فن است، اما مدل های پیشرفته تر دو یا سه فن بزرگ را نیز در خود جای داده اند. اهمیت سیستم خنک کننده تا حدی است که در انواع ارزان قیمت NAS که امکان تعبیه فن های قدرتمند وجود ندارد، قابلیت های نیازمند پردازش سنگین (نظیر ویژگی تحمل خطا یا و بازیابی) نیز که باعث افزایش دمای پردازنده و تجهیز می شوند، حذف شده است.
