Any advice would be greatly appreciated.
The 1012 is fanless. My 1012 with an SSD is every bit as quiet as my Mini 9.

The 1012 is uglier than the 9, though. The 1012 looks good when you're using it, but it's not pretty from the side and back (the battery bulge and while bottom plastic look awkward). The upcoming 1018 (a slight 1012 refresh) looks alot better with it's dark bottom plastic... in pics at least.

Default Utility to reset ssd on Mini 9? - 08-24-2010, 02:59 PM

Thanks Reflex for your prompt reply and thoughts. I don't think the butt-ugly appearance would bother me too much- the beautiful sound of silence will drown it out!

I just read a few of your posts about restoring a bogged down SSD by running a sequential write across the entire disc- have you tried this with success?

Do you know if the 1012 or 1018 supports TRIM?

Trying to learn the best way to keep an SSD running like at least close to new- would love to see a comparison of TRIM vs. other utilities...

...But especially would like to just find a completely silent netbook that will allow me to restore/reset/TRIM/whatever the SSD when it slows down before its time...again, I wouldn't mind yanking it out and restoring it in another computer if that's the only choice (but I don't know if this is a) possible and b) how).

How do you like the mini 9 vs 1012 re keyboard?

I wouldn't call the 1012 "butt-ugly" From the user's perspective (screen and keyboard visible), I think it's attractive. But I think the two-tone color scheme and battery bulge look awkward. I think Mini 9 looks good from all angles.

As for SSDs... My Mini 9's performance seemed to be slowing down (seemed like common "SSD stutter" on random writes). So, I performed a complete wipe of the SSD. I benchmarked before and after, but it wasn't conclusively better or worse. And I haven't used it enough since to give a human opinion.

I think the 1012/1018 should support TRIM, but I don't think my cheap SuperTalent SSD does. I've performed tweaks I hope improve performance, including "short stroking" the 16GB ST SSD (~4GB unpartitioned space). I hope that the unused extra space will keep performance degradation at bay.

If the 1012/1018 doesn't support TRIM, and SSD performance deteriorates, pulling the drive and wiping it in another computer will be easy, its 2.5" SATA drive will plug right into a laptop or desktop.

And about the keyboard, the 1012 keyboard is far superior. The Mini 9's works well for A-Z, but it has missing and moved keys that annoy me greatly, particularly the apostrophe/quote key. I also dislike the tiny right shift key. The 1012 is quite normal in comparison, but I still miss true PgUp/Down, Home and End keys, which require you to do a Fn+arrow key on both.

There is a different keyboard for the Mini 9, US-International, which is more normal, but it's keys are smaller, too. You can probably find it on the forums or eBay.

As far as I know, all of the Minis are fanless. if you want an SSD in a model such as the 1012, simply buy a 2.5" SSD for it. The performance will typically be better than even the best RunCore SSD for the Mini 9.

Default Solution for mini 9 Trim support: get a 1012? - 09-14-2010, 08:34 PM

Thanks for your replies reflex and holmes- especially the details about the keyboards- I see Best Buy sells 1012s now, so I'll go check it out. It sounds like the 1012 is the perfect solution for me- completely silent with an SSD- and the ability to put a regular 2.5" SSD in there that can be restored to nearly new performance when it starts to lag (newegg has a OCZ vertex 2 60gb for $124- seems like a good deal?)

thanks again for all your advice

I can confirm that TRIM is working in linux on a Dell Mini 9.
I am running ubuntu 10.10 which stock has the 2.6.35 kernel and put the discard option for my ext4 partition (in /etc/ftab file). I tested hdparm: created a file, read its location, read the bits of it, removed it, waited 2 mins and read its bits and all 0's! I dont think this means anything for Windows 7 as mini 9's bios do not support a certain HDD mode....

You need a ext4 or BTRFS (not stable yet) partition, kernel 2.6.33 or greater, and to add the discard option in /etc/fstab to ext4 partitions you want to automatically trim. Ohh and an SSD that supports trim, can be checked with hdparm i believe.

I don't think your test means anything either. As far as I know, the only way to really test TRIM is to test performance after cycles of filling up the SSD and deleting the files. See the articles at anandtech.com for examples.

Id rather not fill up my ssd over and over lol, anyway I'll read up on it more and test to see if I can mimic the same results without the trim parameter (discard) in /etc/fstab.

As best as I understand it, what TRIM does is return a deleted block to the free pool. This is below the level of the OS and there's nothing about zeroing the block.

I'd expect that reading a TRIM'ed sector should normally return zeroes (it seems like the easiest response). Although, the controller is free to do whatever it wants.

So, I think josh4trunks test does suggest TRIM is working, but ideally you'd want to test with raw device IO on an unmounted partition to ensure that the filesystem or OS isn't interfering. Maybe the ext4 filesystem driver is lazily zeroing out the sectors itself.
