The 1 TB-ish SSD: The Micron M500

Dave Farquhar Hardware, security , , , ,

Anandtech has a review of the Micron M500, which is the first 960 GB SSD to retail for less than $600. Micron had to make some decisions to get that combination of capacity and price, so it’s not truly a no-compromises SSD, but like the article states, it’s a not-quite-a-terabyte capacity at the price that the best 80 GB drive was selling for in 2008. That’s a long way to come in five years. At $599, the price is high, but it’s not out of reach. If you really need that much high-speed capacity, you can probably come up with that sum.

And the drive’s reception has been very good. It’s backordered everywhere I’ve looked. Read more

How to schedule scans with Avast (even the free version)

Dave Farquhar security , , ,

Scheduling scans with Avast is easy, as it turns out, if non-obvious. Launch Avast, then, non-intuitively, click Scan Now. Click Settings, then, buried on the left is an option called Scheduling.

I recommend doing a quick scan at least once a day and a full scan at least once a week. If you’re using Avast as a secondary scanner, be sure to have your primary scanner scheduled to perform scans too. Read more

SSDs and built-in encryption–and how to enable it

Update: This entry was based on preliminary information that turned out to be incorrect. Please see the following update.

One of the last knocks on SSD performance is that they don’t perform well with full-drive encryption. But on Sandforce 1200- and 2200-based drives, and the next-generation Intel 320 drives introduced today, that’s not an issue anymore. Encryption happens on the drive, in hardware, with no performance penalty.

The problem was that nobody talked about how it works. I found the details buried in Anandtech’s review of the Intel 320 drive. The takeaway is this: If you set your BIOS password, the drive will be unreadable if you remove it and put it in another system. Update: No it won’t. But you can add ATA password support, under some circumstances.
