According to many, USB standardized organizations have made many claims that USB 3.0 will come to smartphones and tablets this year. This is important to our industry and will make things a lot better. These units will have microUSB ports located on them that will allow this manner of connection which will fit all different size devices. The ports will allow faster data transfer between mobile devices and hosts such as PC’s, some of which will already have USB 3.0 ports located in them. Data transfer rates will be roughly between 800 to 1000 Mbps (MG per second). The current port connection is USB 2.0 and the upgrade to 3.0 will greatly improve speed. A data transfer with USB 2.0 that takes 15 minutes will be greatly reduces to 1 minute with USB 3.0, quite a difference. As a result tablets and smartphones will recharge much faster via USB 3.0.
External Data Storage Archiving Case Study – eSATA Attached Drive Usage Example | BVA IT Consulting Blog
Some months ago BVA was struggling to get more speed out of a client’s tape backup. We attempted updating firmware, drivers, and changing jobs but it did not yield the result we were expecting. During this time we were also running out of room on the main file share which slowed down the backups even more. One of our team members suggested to the client an archive process where we would move stale data to an external storage device. The client approved the process and we suggested that we could use this storage device to do backups to disk instead of tapes. Long story short, the BVA engineer went looking for a fast interface device with lots of storage that wouldn’t break the bank. An external eSATA device with 4 1TB drives for $600 was found.

The box comes with 4 drives, RAID controller, and an eSATA PCI-x card. We had to install the card on the server and just plug it in. The enclosure has its own RAID controller and the manufacturer sends it as RAID 5 so we got 3TB from it. Backups got faster. When other clients ran into a similar problem – low disk space/low budget/LOTS of Mac projects needing backups, I suggested this drive to them. This time however, the same drive was $450 (even cheaper).
I think the drive is a good external solution for non-critical data or data that doesn’t require the speed of Serial Attached SCSI. If everything runs as it should, the interface transfers data at 3Gbps which the same as an internal SATA drive.
