What fit-PC Slim version to use?

Post by admin »

As I got some requests which fit-PC Slim version might be the right one, some thoughts on this...

From my point of view diskless version is the appropriate one. I had problems in getting the so called "Barebone" version booted from USB drive during install. Looks like barebone has older Bios. I am in contact with compulab to fix this, but this is still in work. So go with the "diskless" version.

From my experience can't recommend to use a 2.5" hard drive. I tested with one and it got very very hot. With a 4 GB SSD from Transcend temperature stays low and operation is extremly robust. 4 GB SSD costs here in Germany about 45 Euro (i.e. TS4GIFD25), so not that much more than a classical HD. 4GB is completely fine for collecting data for many many years. As fit-PC can just hold one drive, operation of more than one drive is physically impossible.

you´ve mentioned in your early statement about the new platforms, that the power consumption of the new devices will be <10W.

According to the specs of the eBox-4300 / 4310 the power consumption is 15W,
meaning that the new platforms would consume almost double the power of an NSLU2.
Is this correct?
* Fanless
* Support VESA mounting hole
* Compact Flash Slot
* 2 x RS-232 (Optional)
* On-board 10/100Mbps LAN
* PXE diskless boot
* Wireless LAN (optional)
* 2.5” Hard Disk installation
* Ultra Low Power (15 Watts)

Power consumption of eboxes is given under the assumption that you put a 2.5" hard disk into it.

We don't do that. When operating with CF card only the power consumption is below 10 watts, even with RF adding a watt or two.

On their Forum there are several messages about heat, including one where they mention
about 45 deg C in room temperature... tested in ambient temperature of 85 deg C and worked perfectly

Was your very very hot, hotter than that?

They seem to argue that the case gets hot because heat loss from case itself is the means of cooling!

I was testing it with a 80GB 3 years old Hitachi 2.5" drive (HTS721080G9AT00). This unit made the total case that hot, that it was unpleasant to touch. If you keep it firm in your hands you want to put it away after about 5 seconds (don't know what temperature that might come close).

I think this heat won't be a problem for the fit-PC Slim, but I doubt that a drive does like that, especially when in non-stop operation. My drive failed after a week. My guess is that heat killed it. But I cannot say for sure, may be it was just bad luck. Modern drives might be less power demanding and might not add that much to the total temperature bill... I don't know.

What I can say for sure, that with the SSDs the whole case stays away from getting hot... and you don't have to worry about live span of laptop drives.

Sounds pretty hot. I guess you could always stick a CPU passive heatsink on the case to increase the surface area! LOL

Indeed, though AIUI Flash based SSD has a limited read/write cycle lifetime too.
I guess everything is going to fail some time (but only week would be very disappointing!)...

Just a follow up on this. I was already "in the market" for a low power 24/7 platform for WD. I had in mind the Asus eeeBox, however I've decided to try a Fit-PC with Xp instead (lower 'power' than the eeeBox in both senses of the word!).

If the Fti-PC proves not to be suitable for WD either because of lack of processor power or because of other factors such as heat I'll get an SSD and the Fit-PC will become a Meteohub server (I could find alternative use for the 2.5" hard drive too).
If the Fit-PC is up to the WD job, I'll then need decide on whether to continue with my experiments in getting Meteohub onto an Asus eeePC, or go for new hardware such as another Fit-PC...
