Default should i upgrade ram? - 12-22-2010, 10:43 PM


should i upgrade ram?

under normal condition's i am using just under 500mb ram, 77mb of swap which seems to be just right.

i plan to use her to experiment with a usb raid 1 soon. performance in this role is uncertain so my first array will be using two 16gb usb sticks. if that works out i will scale up the raid as needed.

if there should happen to be race condition's on the bus under the raid would adding more memory help?

thank you.

~alonzo, mini 9, run by ubuntu 10.10 netbook remix, 1gb ram, 30gb ssd, 1.5gb swap space, web cam, Bluetooth ,,, it runs ~real~ good!

I like having plenty of RAM, so that I can manipulate files on a blazing fast RAM disk. I routinely have hundreds of MB of files in RAM But 1GB of RAM is sufficient for a basic machine that doesn't have crapware running.

As for using software RAID across multiple USB drives, it should be a good learning experience. You can play around with LVM, mdadm, or btrfs multiple drive configs without threatening "real" data. But it seems pointless aside from being practice.

Ram is cheap, and while you may not see some massive bump in performance you should see programs load faster and be more responsive. But yes reflex is right you will run rather happily with 1 gig. Note that your system will adjust to the amount of ram present and while right now 500 is being consumed after adding more ram this will increase.

So absolutely upgrade to 2 gig, unsure what the advantage will be in running raid 1 as the write speed onto the USB stick is probably going to be pretty slow. But for bragging rights it is probably worth having a go.
