I have avoided pestering readers of this page with announcements of the last couple of Photon-light sales. This one's quite nice, though.

For the duration of the US Fourth of July weekend, they've taken 15% off everything in the store, including a bunch of oddments that you might not expect people famous for high-quality key-ring flashlights. They sell excellent-quality Maha NiMH batteries and chargers, some Leatherman tools and, as they say, more.

Use the coupon code "FIREWORKS" at checkout to get your discount. And, as usual, I get a cut if you click my link to the site and then buy something.

Herewith, a product of considerable interest to Australians and virtually none to everyone else:

Noontec V-9T

The Noontec V9-T, a neat little networked dual-tuner PVR and media player of exactly the sort that big media companies want to sue you for owning.

(Note that this device is pointless for non-Australians because its TV tuners only work with our, unique, free-to-air digital TV system.)

Another Photon-light sale!

The US dollar's in pretty lousy shape at the moment, so this could be a good time for people outside the USA to buy some stuff from the Photon factory outlet.

The current "October Pre-Holiday Sale" takes 15% off all Photon lights, Maha batteries and chargers, and Leatherman multi-tools, which they now also sell for some reason.

The 15% discount also applies to their expensive but good variable-brightness "Photon Pro" one-AA-cell light, which has been upgraded with a significantly brighter high-power white LED, in addition to its little red LED for when you don't want to lose your night vision.

In the unlikely case that you have not yet bought quite enough Photon lights, they've got another sale running now. The list prices for various of their products have been reduced a bit now, and there's a "March Madness" sale running on top of that, until the end of the month

2Tb under $190!

(updated July 5th, 2010)

Samsung EcoGreen hard drive

Yes, the formatted capacity of a "2Tb" drive is, as I've discussed ad very great nauseam, actually only about 1860 gigabytes.

But prices continue to inch downwards; you can now pay only about $AU185 for one, including delivery anywhere in the country.

M'verygoodfriends at Aus PC Market currently sell a "2Tb" Hitachi DeskStar  3.5-inch, 7200RPM, 32Mb-cache SATA drive for $AU185.90 including delivery anywhere in Australia.

That's only about ten cents per real gigabyte (or "gibibyte", if you prefer).

Aussie shoppers who like the idea of that can click here to order one (or more!) of the DeskStars.

Aus PC Market also still list the "2Tb" Samsung EcoGreen, like the one I reviewed a while ago, only twice the size. That has a 5400RPM rotational speed for lower power draw and heat output, and is only $AU183.70 - or a little less, for regular customers. As I write this, though, the Samsung's stock status is "pre-order", suggesting that the local distributor has run out of stock, and/or a new mode's on the way.

They've got stock of the "1.5Gb" EcoGreen, though. That formats to about 1396 real gigabytes, and now costs only $AU130.90 delivered - so it costs only about 9.5 cents per real gigabyte.

This tiny value difference is, of course, of little importance. But if you only actually need 1400-odd gigabytes, or if money is just a bit tight, it's nice that you get about the same capacity per dollar whether you buy a 1.5Tb or 2.0Tb drive.

(There's not a lot of performance difference between 7200RPM and 5400RPM drives, by the way; the slower-spinning drive has proportionally higher rotational latency, but both have huge sustained transfer speeds, because of their immense data density. I'd go with 7200RPM for a computer's boot drive, but even then the difference isn't huge.)
