What's the speed on the 120Gb like?

I heard the SSD had horrendous speeds, and uses a 1.8" ZIF connector.

Is the 120Gb version using a SATA-to-1.8" ZIF? Or just a simple SATA to motherboard?

Is the 120Gb performing like a standard 5400rpm HDD when it comes to read/write?

 

i dearly hope it runs winxp better than the ssd

It appears to be a 2.5" SATA drive. If "macles" is correct, there are different drives used, but any one of them should be quite healthy in the speed department.

 

ill probably replace my hdd with a bigger one at some point

 

Sorry to necropost, but I'd rather put this in a current topic than a new one:

I'm looking to buy the Aspire One soon, but I'm struggling to choose between the HDD and the SSD versions. I'll likely be running Linux (probably a Debian based distro), but I'm wondering if there's any real advantage to the SSD version, aside from no moving parts and silent running, which don't bother me so much (remind me, who operates their laptop whilst moving anyway? ). Also, is performance impacted when using the SD expansion slot? I can get a 32GB SDHC card to expand the storage, but it makes me wonder if my system performance would drop like a brick as a result.

Also, If I want to upgrade the SSD later on, would it be as easy as upgrading the HDD? Is it possible to swap between the two versions?

Does anybody have some comparison tables rating performance of the different storage devices, with and without an SD expansion installed?

 

I installed a 320GB hard drive not too long ago. I like having huge amounts of storage space.

 

Yeah I did that, and then a week later 500GB drives start showing up! Ah well.

 

I quite often like to move my laptop without shutting it down first, I may even choose to use it as a frontend to my MythTV box and I might choose to carry it to the kitchen if I want a drink or snack rather than pause the program I'm watching. So, to answer your question, I do.

No, it doesn't impact performance, the internal SSD is quite slow, particularly with writes (I'm saying that with the faster Samsung SSD in my Aspire One), so as long as you buy a decent SD card you may well get better performance from the SD card than the SSD. If you plan on using the expansion slot to increase the storage, bear in mind that Acer do this in software on Linpus using Aufs so if you want this on another distro it may take a bit of work to set up.

The SSD version uses a 1.8" ZIF connecter and the HDD version uses a 2.5" SATA drive and has a slightly bigger case, so if you wanted to upgrade the SSD version you'll have to replace it with a 1.8" drive, but it can be done so long a you're comfortable dismantling the Aspire One to get at the drive, but you won't be able to put a 2.5" drive in without some difficulty.

 

Apparently 2.5" 500gb HDDs are taller than the smaller capacities and so it won't fit in the One, or any other notebook (and PS3) that uses what has, up to now, a standard bay size for 2.5" width drives.

 

I'm assuming that you can get a converter to replace the 2.5" SATA HDD with SSD storage if you wanted to though, right?

 

I'm sure you can, you can also buy SSDs in that form factor, though they aren't cheap but do they do have more space and are a lot faster than the AA1s SSD.

 

My 120 GB HDD on Acer One is very low speed by writing and reading 1,2 mb.I am runing a Windows XP SP 2.Some with similar problem and fix?

 

ive got the 120gb one, linpus based version, incredibly quick to me, its easily on par with my bigger home pc on speed (and its a dual core p4 2.8

 

If you're using Windows XP, make sure you're testing properly. Go to
http://www.hdtune.com
and download and install the free HDTune application.
Shut down as many of the background apps running on the toolbar near the clock and run the test. I get between about 53 and 58 megabytes a second read speed.

 

Yes im testing with hdtune,and speed is 1,2mb.

 

I have HD Tune Pro 3.00 and this is the speed of my hdd on aao.
