Pros: I am using this as my primary genomic dataset decompression/analysis/recompression drive. It replaced the competitor’s highest-end consumer-grade performance hard drive, which also has a five year warranty. Sustained writes of 170MB/s are amongst the highest I’ve seen from a single (mechanical/platter-based) hard drive. For comparison, the drive it replaced topped out at 150MB/s according to my testing. This Seagate drive also has slightly lower latencies than the drive it replaced. At idle it pulls a few watts less than the drive it replaced. Finally, it is noticeably quieter (though in an enterprise setting this is irrelevant).
Cons: It runs a few degrees warmer than its predecessor (it’s in the same spot in the same case so I am confident in that assessment). The system also pulls 2-3 watts more under sustained use as measured from the wall controlling for the addition of the SAS controller card I installed.
Other Thoughts: Moving from a high-end consumer drive to this enterprise drive yielded minor performance increases given my usage scenario; I am most pleased that it is quieter than the drive it replaced though as alluded to most purchasers likely will not put this in an mATX case that’s sitting on a workstation desk. Of course, I unfortunately can’t yet comment on one important aspect of a hard drive, reliability.READ FULL REVIEW
This review is from: eFun Touch 8 XN800 Black USB 2.0 IR Wireless Touch Pen
Pros: The included instruction manual is clear and setup/installation of the device is a breeze (took less than a couple minutes). I tested this on two non-touch screen laptops and a desktop PC, all with Windows 8 installed. I have not noticed any input lag, and the included stylus and sensing device are accurate. It's supposed to work with laptop monitors up to 17", and it also works on my old school 19" 4:3 monitor. (It does not work with a 24" 16:9 monitor, but the manufacturer doesn't claim it will so obviously that's not worth docking an egg over - just providing information.) It's nice to be able to use a touch interface on Windows 8.
Cons: None, really. It works as advertised.
Other Thoughts: Even if you have a touch-enabled W8 device, if you're a bit compulsive about keeping your electronics extremely clean & tidy like me, you could use this and not get your screen dirty with fingerprints.
Note, this also works with Windows 7. I tested it on a W7 laptop and functionality was fine; it worked just as well as it did with W8. The manual indicates it will work with Windows XP but as I no longer have any XP devices, I can't verify that claim.
Pros: This card's performance is noticeably higher than the 7770 GHz Edition GPU that it replaced. It's not quite as impressive as the 7850 1GB I have in another machine, but its performance is closer to the 7850 than the 7770. Power draw (as measured with a Kill-a-Watt) is closer to the 7770 - in fact, the 7790 pulls only about 10W more than the 7770. The 7790 scores a 7.7 in Windows 7's Experience Index, and I can play Far Cry 3 passably at 1080p on Ultra Quality, though it's much smoother at 1080p on Med-High Quality. Crysis: Warhead manages about 40-50 frames per second at 1080p on Enthusiast/Good, and BF3 at 1080p is 50+ fps on Ultra Quality.
Other Thoughts: The performance is more like a 7850, the power draw is more like a 7770, with the game bundle the price is more like a 7770. If you're considering a 7770, then seriously consider springing a few more dollars on a 7790. The price:performance ratio for these 7790s is the best in AMD's GPU lineup right now, in my opinion.READ FULL REVIEW
