Re: Efficiency vs load analyzed for 20 PSUs

Wow, these charts are awesome and really help visualize the difference in efficiency between PSUs - in particular the low-power portion which is of particular interest to me. Nicely done!

The SS-350TGM really stands out in comparison to the rest at low power thanks to these charts.

Re: My house idles at 75W

Eventually, we'll be building a new Off Grid home and we're working to get our total demand down so a 1Kw PV array is large enough. Our current demand is over 44Kw per day according to our electric bill. That's what we really need to drop and I'm hoping to get down to below 5Kw per day. Not sure wh...

For a mini PC, yes, the picoPSU+brick is great. But for mATX or small ATX case, I'd take the G360 hands down. What you get for the price is unmatc...

Re: Seasonic G360W gold for $60 - Review & Giveaway!

Nice looking PSU - 360W is still overkill for my PCs. I'd love to see a 200W PSU with efficiency numbers pushed up to 90% at lower power outputs, especially in the 30-50W range where most PCs spend their time idling these days.

It needs to be a single partition, i.e. you do not place any other partitions on it, which you access and which totally kill the performance increase of the short stroke partition. It totally depends on your usage patterns. If for example, you take a common setup of putting your OS, programs on the...

so completing our large tasks faster still won't get us back to idle state for long. The primary benefit of short stroking a drive is to reduce seek times. For example, short stroking their 450GB 15k SAS drive to 45GB cut seek times from 6ms to 3.8ms. For the 250GB 7.2k SATA drive short stroking to...

It doesn't matter what OS you are using, you want to make sure that the filesystem data blocks are aligned to the data blocks on the SSD.

For anyone with one of the JMicron based SSDs, you can often significantly reduce the effects of stutter so that it's often not noticable by making sure the partition is aligned on the proper boundary. For example, Vista does this by default by aligning the partitions on 1MB offsets, but older versi...
