This review is from: Seagate Expansion 3TB USB 3.0 3.5" Desktop External Hard Drive
Pros: - Reliable
Cons: - Bulky
- Needs AC Adapter
Other Thoughts: I purchased this drive in September 2012. It's now May 2014 and the drive is still working great. I'm a mobile DJ and I use this to carry my music collection to gigs. I have a streamlined "emergency" library on my laptop's internal HDD, but this drive contains my entire library.
The drive sees some minor-moderate abuse being transported frequently and occasionally bumped into, and has had zero issues. (I've never dropped it from a significant height or anything).
This review is from: Lenovo IdeaPad U310 43752CU 13.3" Ultrabook
Pros: - Looks nice. Basic but sleek metallic design, resembles a macbook actually (especially black keyboard keys on silver inside)
- 2x USB 3.0 ports with good transfer speeds (SuperTalent 32GB gets ~109MBps on multi-gigabyte file copies)
- i3-based laptop under $500 (as of this review)
Cons: - Wifi is useless. See other thoughts.
- Trackpad is mediocre, as stated in other reviews. Make the buttons a separate piece of plastic from the actual touchpad and it wouldn't be so bad... silly Lenovo. And no, this isn't like a Macbook where the whole pad pushes in; you're literally bending the edge of the plastic pad to click the left and right mouse buttons.
Other Thoughts: There is a 68-page thread on Lenovo's official forum regarding the Wifi issue. They refuse to publicly release their fix, which is hardware-based; they insist on having customers send it in. Even then, many customers who sent it in for service report no improvement in wifi when they get their unit back. I believe the problem is the antenna design, possibly related to the metal case... it can't be the Wifi card itself, since Intel, Broadcom AND Atheros cards were used and all exhibit poor range and speed issues.
My old Lenovo Y550P gets great speed with my Asus RT-AC66U router... however the best this U310 has done is to connect at a link rate of 48Mbps. Bottlenecks my Comcast blast 50Mbps download speeds to 13Mbps... if I'm right next to the router. 8Mbps in the next room.
Note the lowercase "b" i'm using... mega-BITS per second. Not mega-bytes. 13Mbps = 1.63MBps.
If you're buying an ultrabook, you likely want to have something you can carry with you and hop on wifi hotspots, etc. Therefore, bad wifi is kind of a dealbreaker :( Even at the sub-$500 price I got this for, I'm going to return it. Disappointing, because aside from Wifi this is a nice little machine. If you're willing to plug a $20 3rd-party dongle in one of the USB ports and do it that way, then go for it. Thi
Pros: - External antenna base is great, every desktop PCI/PCIe wireless adapter should come with one
- Full 3x3:3 802.11ac capability
- Pretty red heatsink
Cons: - Not outpacing my 802.11n 2x2:2 adapter in network speeds, see other thoughts
- Passmark Performance test graph shows a very unstable connection despite -37dBm signal level. Smallnetbuilder.com was able to get much better results in their "across-house" setup which is 'geographically' similar to mine...
Other Thoughts: I was really excited about this adapter. I set up auto-notify and ordered as soon as it came back in stock. However, it's been kind of a let down for me.
I have this paired with my Asus RT-AC66U router, latest .266 stock firmware. The best I've been able to achieve is 25MBps, or 200mbps. My 2x2 Rosewill USB 2.0 Wifi-N adapter was easily getting that, and even a bit higher at times, with the same antenna location. Pingtest.net (part of speedtest.net) shows a slightly higher ping (~22ms) and more jitter when I use this adapter vs. when I use the Rosewill (~14ms).
The Asus utility that comes with the card has typically indicated a link speed around 250Mbps, occasionally jumping to 575Mpbs (but not often, and for no apparent reason). For a few seconds after initially connecting, it shows 1300Mbps, but that quickly goes away.
I'm getting -37dBm on the 5GHz band, which should be plenty of signal strength to achieve full speeds.
I even have a PCI slot cooling fan mounted in the slot right below the adapter's heatsink to exhaust hot air away from the adapter.
I hope that with time I'm able to find an issue and unleash the full performance here, but so far I've been stuck with $20 adapter performance after paying a $100 price :/
