This review is from: Logitech 993-000439-01 Unifying USB Receiver for Mouse and Keyboard
Pros: I've had many of these and they always fail after a while. Who would have guessed that keeping a computer in mice could be so expensive?
Cons: Poor build qualityREAD FULL REVIEW
Pros: Light weight, touch screen
Other Thoughts: After trying out the Win8 ultrabook in the store, I was impressed that it seemed very usable and was truly ultra light with a great screen resolution. My previous Vaio notebook was only a couple years old, but I decided the higher screen resolution and light weight were worth the upgrade.
My first problem was dropping network connections frequently. After a long call with support, they confirmed that an update had been released to the wireless driver several weeks before my laptop had been shipped. I understand why they may not be able to update the image they use for the laptops, but not even notifying me of this known problem is terrible customer service. Unfortunately, that was only the first of many problems, and coincidentally the only one that was solvable.
Next thing I found was that the laptop was waking up. I do windows administration part time, so I understand the various reasons windows wakes up. On this laptop, even though the device settings are adjusted to prevent the laptop from waking up, it still wakes up. What's worse, on reboot the laptop loses the device manager settings which are supposed to prevent it from waking up. After months of troubleshooting, I have finally sent my computer in for repair.
The brighness adjustment stops working after a couple of wake/sleep cycles. If you think for a minute about the wide variety of lighting conditions in which you have to use a laptop, you quickly realize how frustrating this is. In a bright room, it gets stuck so low that you can't read the display. At night, it remains so bright it's blinding. It's a toss-up as to where the brightness gets stuck. The workaround? Reboot which makes it work for a short time.
Closing the lid often causes the computer to crash, losing work in progress.
Letting the computer sit idle, whether plugged in or on battery causes the computer to shut down, regardless of what the power settings are. Again--losing work in progress.
Screen does not always come back on after closing the lid, which means another forced restart losing any work in progress.
Since the 8.1 upgrade, copy/past keyboard shortcuts work intermittently. It now usually takes 2 or 3 attempts at control-c to make a copy.
This computer has never worked properly and I have never been able to use it. Sony's answer is to send the computer in for repair. I could understand that if at one point the computer worked, but IT NEVER HAS. I am so frustrated I have asked for a refund but they have refused. Sony asked that I send the computer in for repairs, which I did. They reimaged the hard drive and updated the BIOS and upon receiving the computer back I found that the sleep setting is still reset after reboot. They obviously did not even test the computer before sending it back to me. I am continuing to ask for a refund, but I am preparing for the worst (legal action against Sony based on computer lemon laws).
Pros: * Relatively compact for 5 drives
* Synology Hybrid Raid
* Light weight (without disks)
* Quick setup
* Very quiet
* Fast/responsive UI
Cons: * The drive bays are very light-weight/fragile plastic, although I hope that I hardly ever have to touch them.
Other Thoughts: Upgrading from a QNAP TS-409 Pro. I'm very impressed with the DSM firmware so far--very easy to use. I scanned the manual but really didn't need any instructions to do the setup and start building the SHR array. One factor in the choice of this unit was expandability with the optional external drive chassis, though there aren't a lot of reviews on how well that works...so here's hoping. The other reviews pretty well cover the pros, so I'll stop here and update if I have any other findings that would detract from the 5 egg review.
Installed 5 x ST4000DM000 4TB drives using SHR with 2 disk fault tolerance for a total capacity of 10.4 actual TB.
