Acer Aspire One D250

The Acer Aspire One D250 is a decent netbook and was sold usually with Windows XP Home or Windows 7 Starter, 1 GB of RAM, a 160 GB hard drive and a 1.6 GHz Intel Atom processor. While the best thing to do to improve performance is to install more RAM (the maximum being 2 GB), the next best thing to do to eke out more performance from these cheap netbooks is to either replace the existing hard drive with a faster model or to replace it with a SSD (Solid State Drive).

Why Replace The Acer Aspire One D250 Hard Drive


One reason to replace the original drive is to boost performance. The original hard drive rotates at a speed of 5400 RPM. This is relatively slow, even by modern standards. One option is to replace it with a drive that rotates at 7200 RPM. This will mean lower seek times (how long it takes the drive to retrieve data) and can improve boot and application launch times. Of course, this also comes at the expense of reduced battery life and an increase in the amount of heat produced by the netbook.

The solution to this, if all one cares about is fast boot and application launch times, is to replace the original hard drive with a SSD. SSDs are faster than traditional hard drive as they have no moving parts. This also means that they consume less energy and produce less heat. The drawback of SSDs is that they currently carry a higher price tag and offer less storage than cheaper hard drives.

Of course, you may just need extra storage space. You don’t have to opt for a faster hard drive in this case. Currently, 2.5” hard drives are available in capacities up to 1 TB, which is more than six times as much storage as the original 160 GB hard drive that came with your netbook.

How To Replace The Hard Drive In An Acer Aspire One D250 Netbook


It’s fairly simple to replace the hard drive in an Acer Aspire One netbook. Simply shut it down, remove the power cord and remove the large panel that has two screws locking it in place. Now, we must remove the caddy that the current drive is installed in. It is held in place with a single screw. Remove the screw and slide the caddy towards you or towards the front of the netbook. Lift it out of the netbook.

Now, the hard drive itself must be removed from the caddy. It is held in place with four screws, two on each side of the drive. Remove those and lift the caddy off. Now, you can attach the caddy to the new hard drive or SSD. With the drive face up (the label, logo and drive information are on this side), place the caddy on top with the section that is screwed into the netbook on the right. Reinsert all four screws and tighten them.

Gently insert the caddy with the new drive into the netbook. Slide it in the opposite direction to connect the drive to the SATA power and data connections. Screw in the caddy to lock it in place and reinstall the plate along with its screws.

Complete The Installation


Power your netbook on and make sure that it is recognized in the BIOS. Now you are ready to reinstall Windows or your OS of choice, unless you have already cloned the original hard drive to the new one.

About Using mSATA SSD's With The Aspire One D250

The Aspire One D250 has a mini PCIe slot on the motherboard. However, mSATA SSDs won't work in this slot as the slot itself is not wired to pass SATA signals for the BIOS to read it as a storage device. The mini PCIe and mSATA connectors just look the same. So, don't buy an mSATA hard drive or you'll be sorely disappointed. Your best option is buying a 2.5" SSD in a large size capacity that supports the SATA III standard (up to 6 Gb/second/600 MB/second). That way, you'll have an SSD that you can install in another laptop or desktop computer if your Aspire One D250 breaks or fails.
