Taobao product recommendation – Orico Dual Bay Hard Drive Dock

These days, with everything going digital, everyone needs some kind of digital backup storage (to store photos, videos, documents etc.). It can be in the form of an external harddisk, thumbdrives, cloud storage (Dropbox, Google drive etc.) or the now-probably-obsolete optical disks (DVD, Bluray). In terms of safety, probably nothing can beat cloud storage, since it is managed (someone guarantees the safety) and it is offsite (you’re fine even if your house is burnt down). To store a large amount of data (in the Gigabyte range), though, it is probably not practical to use cloud storage, since it will be expensive and considerably slow even with the high-speed internet we have today. I’m a cheapo when it comes to.. well, everything, and my choice of a digital backup storage is a hard drive dock.

Prior to this, i used DVD-Rs to backup photos. Although cheap, it is quite a chore to burn the DVDs, plus, if you missed out some files, you may not be able to add to the already burned DVD. The size of DVDs at 3.7GB is usually not enough to contain all your photos, so your photo back up will span a few DVDs, and it is again a chore to load and eject DVDs if you wished to view the photos. The next lowest cost storage available is the hard disk. A hard disk overcomes all the shortcomings of a DVD, except it may not outlast a DVD. Hard disks have a typical life span of 2 to 8 years, with the added risk that they may fail abruptly at any time. The way to tackle this problem is to have redundancy – do the back up onto two or more hard disks. The likelihood of both hard disks failing at the same time is small enough to make this solution workable. In fact, the practice of having redundancy of hard disks has become standard to the point that a standard is actually devised, called RAID 1. For the average consumer, to be able to take advantage of RAID 1 simply means buying a hard disk enclosure or a Network Attached Storage (NAS) that supports RAID 1. The price point of such an enclosure is around US$70 at present (this excludes the price of the hard disks). The advantage of using RAID 1 is that you need only to do the back up once and it will be automatically duplicated onto the hard disks. If, at any point in time, one of the hard disks fails, you can simply replace the failed hard disk and all the back up data will be duplicated onto the new hard disk automatically. The disadvantage of RAID 1 is, well, the price. You do have to pay a premium for having this facility.

The alternative to RAID 1 is to duplicate the back up data onto each of the hard disks manually. This simply means you need to back up the data more than once (usually twice, since two hard disks is normally sufficient redundancy). I have chosen this as my back up solution, because the hard disk enclosure/dock without RAID 1 is far cheaper. I managed to get one from Taobao at 126 Yuan (S$28) – Orico dual bay hard drive dock (USB 3). Orico is a well known Chinese brand that’s sold on Amazon as well. At this price point you can forgive the slogan ‘Easy your PC’ (a literal translation from Chinese that’s supposed to mean making PC usage convenient) and the past tense of back up being spelt ‘backuped’.

You can plug either 2.5 or 3.5 inch hard disks into the dock. Obviously, a 3.5 inch hard disk is cheaper, so you’ll go for that. I got Toshiba 1TB drives since they are the cheapest available (S$61) and they cost only marginally more than the 500GB one. With only 2 years warranty, these probably will not last much longer than 2 years, if it will last 2 years at all, but redundancy takes care of that anyway. At any point in time, if one of the hard disks fail, you’ll get a replacement and copy all the data into the replacement hard disk, and you’re safe again. And the beauty is, neither brand/model nor the capacity matters. You can just get any harddisk that has at least the same capacity, or more.

First test run of 10GB back up took 4 minutes to be copied into both hard disks, not bad. To make it easier to copy files to both hard disks simultaneously, i used the utility n2ncopy. My 4 years old laptop didn’t have USB 3, but thankfully it came with an ExpressCard expansion slot. I got hold of a USB 3 ExpressCard from Taobao for 38 Yuan (S$8.50), which is dirt cheap. So, for a grand total of S$166 (inclusive of shipping cost), i managed to put together a 1TB redundancy back up solution with decent data transfer speed.
