Price is in USD (US dollar, $). You can pay in a different currency, if you wish; convert it using xe.com currency converter and pay the new amount instead.
The brand used varies, but Minifree will use a quality brand such as Kingston or Samsung. Compared to a typical HDD (hard disk drive), an SSD (solid-state drive) offers low power consumption, faster read/write times and quiet operation. Your operating system and applications will load faster, and it will be more responsive.
Purchase this along with your laptop, and the laptop will come with an SSD. (without this upgrade, laptops have 250GiB HDD)
