I would not go out of my way to make sure everything was USB 3 on a new setup until it becomes more common place and devices support it. I also do not plan on replacing every external hard drive on usb 2 I have right away, so I don't think it is worth the cost at the beginning. I guess it really depends if you are buyi... |
Whatever your decision, there will always be an expansion card available. |

SSD are already SATA2 (and SATA3) bandwidth limited when doing seq transfers – Pyrolistical Sep 28 '09 at 21:47 |
I knew we were getting close, but I haven't seen any benchmarks that showed a single drive hitting sata2 saturation. If you got a link, that would be cool to see. – Troggy Sep 28 '09 at 21:54 |
Pretty much all second gen SSD that hit 262 MB/s. That's the real world SATA2 limit: pcper.com/comments.php?nid=7527 – Pyrolistical Sep 28 '09 at 23:49 |
@Pyro: Well, SSD performance is just skyrocketing faster than I ever thought. Check out this new SSD coming soon with up to 355Mb's reads: micron.com/products/real_ssd/ssd/client/index – Troggy Dec 7 '09 at 16:11 |
Its all very well talking about SSD's but remember the e in eSata stands for "External". In 5 years from now the general public might be able to afford External SSD's, not at the moment. Another thing to consider is eSata is not host powered. While USB 3 is. – JL. Nov 9 '10 at 18:25 |

Well, I would go with Esata if you can, simply because it would be almost the same as directly plugging a hard drive straight into your machine as a normal hard drive. |
USB is universal by name, it is meant for pretty much any and every device you can imagine. Whilst I doubt there would be any big speed issues, there is no point in using it if you can support Esata. |
All of this is just based on my experience, can't really say anything for sure as the technology has not yet been released. |
The fact is, USB to ethernet adapters work, but a standard ethernet card is faster, usb keyboards work - but most of the time, ps/2 keyboards work more "natively". |
At the end of the day USB hard drive works, but you will be converting a perfectly good SATA signal to USB, when esata is basically just connecting a external hard drive directly to the motherboard in the same way as a internal hard drive. |

Very well said. To extend your answer - why share the USB bus with other devices when you can mainline directly into the sata connector? – JL. Nov 9 '10 at 18:23 |
According to wikipedia eSata standard is still limited to 3Gb/s speed. Do you know if this is still the case? USB 3 is 5Gb/s. If both these are true then surely USB 3 would still be higher throughput. – Matt H Jun 23 '11 at 2:04 |

I'm not quite sure what the dilemma is... |
Most motherboards come with at least on eSATA port and several USB 2.0 ports these days, so if you can get external devices that support eSATA you are better off. As USB 3.0 is adopted, motherboards will continue to offer eSATA ports alongside USB. So any kit you have now will be at least as capable then as it is now. ... |
NOTE: For the time being, eSATA is still faster than USB3.... |

usb 3 is 6gb vs esata 3gb |
usb 3 supports data+power vs esata requires a separate power adapter |
so unless esata starts supporting more bandwidth and power, its win for usb 3 |

A nice theoretical answer – JL. Nov 9 '10 at 18:28 |
Except that SATA is also available in 6Gb/s bandwidth (SATA III) and is usually combined with a USB connector to form eSATAp to provide power (and maybe USB data as well). – Mircea Chirea Jan 2 '11 at 20:21 |

not for hard drives. |
eSATA is isochronous, USB is not. Hard drives operate on SATA, thus SATA is always going to be fastest. USB2 had a 480Mbit transfer rate, but HDD's rarely exceeded 240Mbit. |

HDDs rarely exceeded 240Mbit? That's 30MB/s. HDDs are three times faster than that typically. – Mircea Chirea Jan 2 '11 at 20:24 |

The USB2 interface has a theoretical max of 480Mbit/s=60Mbyte/s (MB), and in practice rarely faster than 30MB/s, whilst the fast SSD harddrives has about 240MB/s transfer rate, NOT 240Mbit. |
I think the only thing actuall differing USB3 from eSATA in practice is power over the same cable, which was mentioned earlier, as this makes USB3 much easier to handle when using portable hardrives and such. Also, the fact that its backwards compatible with USB 2/1 which makes any usb3 unit usable on older systems asw... |

Beware you can't install and boot an operation system on USBx hard drive but you CAN install and boot any system on eSATA drive. With eSATA you can use single portable system (even Windows 7 licensing issues aside) in both office and at home without any speed or comfort sacrifice. |

You haven't heard of USB booting yet, have you? – Mircea Chirea Jan 2 '11 at 20:22 |

Only on older motherboards you cannot boot from USB, and I've indeed run an OS (FreeBSD) from USB memory stick. Possibly you need to enable boot from USB in the motherboard's BIOS. |

One factor to consider is access to SMART data. In all the HDDs I own, SMART data is not accessible over USB. HDD manufacturers will support SMART over USB3 in future. but if you want to check your HDD SMART data now I'd stick with e-SATA. |
For HDDs on the market today (April 2011), you can typically use two HDDs per e-SATA connection before maxing out the bandwidth. |

How Should I Be Taking Care Of My Skin In My 60s And Beyond, And What Kinds Of Issues Should I Be Thinking About? |
Question: How should I be taking care of my skin in my 60s and beyond, and what kinds of issues should I be thinking about? |
Answer: In your 60s and beyond you really begin to notice the ramifications of long term exposure to the elements for your skin. So the first thing is to continue using sunscreen everyday but also to be much more aware of anything on your skin that begins to change color or bleed or become irregular and see a dermatolo... |
You can also use for wrinkles and also sun damage, retinoic acid which helps treat sun damage. And there are things at the dermatologist that can be done, such as laser treatments, intense pulse light treatments, resurfacing treatments that help undo some of that damage. So your 60s are a good time to see your dermatol... |

My questions: |
1. Is users notified when an app has been updated on the App Store? |
2. If so, how this notification is displayed? |
3. How is this update performed on the phone? After user confirmation or automatically? |
I'm an Android user. When an application has been updated on the Android Market, a notification is automatically shown in the status bar. Then, the user can click on it to open the Android Market app and list his applications. Finally, he can click on the "Update" button to upgrade them. |

Isn't this kind off off-topic? – MrThys Aug 4 '11 at 14:46 |
Well, it clarifies what needs to be done (or doesn't) when releasing an update. – Evan Mulawski Aug 4 '11 at 14:47 |
Yes, that's it. I know my app will have to be upgraded periodically, so it's better to anticipate the update procedure. I'm sure it's a stupid question for an iPhone user but don't forget I'm an Android user, not iPhone! – Sly Aug 4 '11 at 15:05 |

On iTunes, a bubble with the number of updates available is displayed: iTunes sshot |
On the iPhone, update notifications are available on the App Store app: iPhone sshot |
The user must choose to update by taping on 'Update all' or by choosing individually which apps to update. |

1. Yes, via the App Store application and the iTunes desktop application. |
2. On the iOS devices, a red notification icon will appear over the App Store application icon with the number of applications ready to be updaed. In iTunes, a similar thing in the Apps sidebar. |
3. On the device, after user confirmation, the App Store app opens. In iTunes, the user is directed to the iTunes Store Updates page, where they can select Update All, or select individual applications to update. |

1. Yes, they are |
2. It displays as a red notice icon on the app store app |
3. The user must update the app manually through the app store. It happens after user confirmation. |
