Seagate's involvement in solid-state storage market shifted into high gear today as the company unveiled four new drives: the Seagate 600 SSD, the Seagate 600 Pro SSD, the Seagate 1200 SSD, and the Seagate X8 Accelerator.

Among these new drives, the Seagate 600 SSD is the first from the storage vendor that's designed for general consumers; the rest are geared toward enterprise use.

The Seagate 600 SSD comes in both 7-millimeter and, for the first time among SSDs, 5-millimeter thicknesses. The drive retains the 2.5-inch laptop design, supports SATA 3 (6Gbps), and offers up to 80,000 … Read more

If the Samsung Galaxy S4 follows in the same path as the S3, we should see two variants of the Android phone with different internals.

Like the S3, the international version of the S4 will likely carry Samsung silicon, while an LTE version in the U.S. opts for a Qualcomm processor.

While we won't know until Thursday what's inside precisely (and we may initially only know the precise specs of the international version), there are two candidates based on reports, including one from J.P. Morgan.

Whatever the case, there's no doubt the S4's high-resolution … Read more

LAS VEGAS--Lexus showed off a prototype version of its safety-focused research vehicle today at CES, and it's designed to be more aware of what's going on around on the road.

That translates to a car that's been equipped with a bevy of sensors and other technological goodies, including a roof-mounted Light Detection and Ranging (LIDAR) laser that can detect objects from 70 feet away.

Other additions include a trio of hi-def cameras that look out for nearby vehicles; a sensor that detects the car's speed and angle; and a GPS antenna that Lexus says can figure out which way your car is pointed even when the car isn't moving. … Read more

If you read my "What is refresh rate?" post, you'll know that plasma TV manufacturers (Panasonic, Samsung, and LG) make a point in claiming a "600Hz" refresh rate on their TVs. As we discussed in that article, it's not exactly comparable to LCD's 120 and 240Hz refresh.

So what is 600Hz, and how does it work?… Read more

With 120Hz, 240Hz, and even 600Hz, refresh rate gets a lot of attention in the marketing of new HDTVs.

What it is and how it works is interesting, but why it exists is even more so. And it can have a profound effect on the picture quality of your HDTV.

Curious?

With the Photokina show in Germany producing so many new high-end cameras, it's evidently been a busy season for Adobe Systems' Lightroom team.

That team just released Lightroom 4.2, which supports 22 new cameras, 43 new lenses, and lets people shoot with 11 new cameras tethered to a computer. It takes work to figure out how to decode each camera's proprietary raw format.

Here's the full list of new cameras supported, but note that the Nikon D600 support is "preliminary and there is a minor risk that the appearance of your images may change when … Read more

Not too long ago, a budget laptop was, by default, a big, ugly plastic box. It may have gotten the job done in terms of school or office work, but it wasn't going to turn any heads at the coffee shop, or fit comfortably onto an airline tray (with the exception of too-small Netbooks, which had their own list of problems).

We'll look back on 2012 as the first year when budget laptops really got a fair shake, with many models looking and acting much more like their expensive cousins than ever before.

Even at the very low end of budget -- laptops that are $600 or under -- you can get a slick-looking HP Envy Sleekbook, or a powerful Acer Aspire V5.

Here are a handful of recent favorites, from 11-inch ultraportables to 17-inch desktop replacements, each of which costs about half as much as a 13-inch MacBook Air.… Read more

Generally, for network storage needs, I would recommend getting a dedicated NAS server, such as the Synology DiskStation DS1511+. However, if your needs are limited to casual usage, such as sharing documents and streaming music and photos, then a router with built-in network storage capability -- one that comes with internal storage or can host an external storage device and shares that with the rest of the network -- fits the bill better.

While much inferior to a NAS server in terms of features and especially performance, some routers actually have more to offer, in terms of storage, than one might expect and may just be what you need. In any case, getting a router of this type plus an external hard drive is a lot cheaper than a dedicated NAS server.

Following is a list of five top routers with built-in support for network storage that I've reviewed in recent years. … Read more

N600 routers are the first true dual-band routers on the market, capable of delivering 300Mbps Wi-Fi speed -- based on the dual-stream (or 2-by-2) setup of the 802.11n Wi-Fi standard -- simultaneously on its two frequency bands, 2.4GHz and 5GHz. The marketing term "N600" basically means "Wireless-N standard with a combined bandwidth of 600Mbps."

In layman's terms, an N600 router comes with two built-in Wireless-N access points. Wireless clients connected to one of these access points (a client can only connect to one access point at a time) will have a ceiling speed of up to 300Mbps. In reality, the real-world sustained speeds of wireless routers vary a great deal, depending on the environment, distances between router and clients, and the frequency band.

In my experience, N600 routers generally offer about 60Mbps on the 2.4GHz band and about 140Mbps on the 5GHz band, within 75 feet or less. And while these seem much lower than the 300Mbps ceiling speed, they are more than fast enough for most applications, including high-definition media streaming. In fact, 140Mbps is about 50 percent faster than a wired Ethernet connection. Farther out, from 150 feet or more, a Wi-Fi connection is generally only good for accessing the Internet and mild networking needs. You can find out more about the basics of home networking here.

Since the dual stream is currently the most popular standard of Wi-Fi used in clients, getting an N600 router is probably the best value for your money. This is because the speed of a network connection is determined by the slowest speed of any party involved, so if you get a faster Wi-Fi router (such as an N900 router), you might not see any benefits at all if none of your clients support the higher tiers of Wi-Fi speeds.

Below are the top five N600 routers among those I have reviewed in recent years.… Read more
