and more stuff which i don't know if would be necessary to state here

Router: Netgear DGN 1000

already i have a topic proceeding in

to make a backup of my precious data, in case those malware tries to delete everything, i am planning to buy a portable storage device (external).


actually my problem involves 2 components: NETWORKING and STORAGE. since one cannot post the same question in 2 topics i decided to post here.
i am planning to buy a portable storage device (external). now that puts me into a huge number of "permutations/combinations" of various specifications like:
1. SSD (electronic flash) OR HDD (magnetic electro-mechanical)
2. port options like USB3.0, thunderbolt, e-SATA, SCSI, firewire, ethernet, wi-fi, and lots more (affects data transfer speed).
3. weight and dimensions - portable lightweight or just external bulky; 2.5 or 3.5 inches.
4. self-powered or external power-sourced.
5. heat dissipation, with / without cooling fan, outer aluminium case.
6. RAID configurations and daisy-chainable or not.
7. Noise.
8. Storage capacity.
9. Cost per GB.
10. Total cost.
11. Shock-proof and waterproof.
12. Reliability and Life of usage.
13. Warranty period.
14. Manufacturing company.
15. RPM of platters(5400, 7200, 10000, 15000) (affects data transfer speed).
16, cache size (affects data transfer speed).
17. Design aesthetics including shape, outer-case material grippability and colours.
18. compatibility with the file-systems of windows, mac, linux, etc.
19. bundled backup software with auto-backup functions.
20. bundled cloud storage.
21. Encrytion
plus any other stuff i am not aware of.

all said, my budget is upto INR 7000. specifications 9, 11, 12 are of prime importance. specification 13 should be atleast 3 - 5 years minimum. specification 14 should preferably be reliable and renowned. i am ok with external powered disks or not. capacity needed is 1TB or more. i dont need bundled cloud storage. i am somewhat contended with windows-compatibility, coz i dont possess any mac or linux products (except my android phone). i am not sure if SSD have higher life than magnetic HDD coz of absence of moving parts, all the same i am not sure if magnetic HDD have higher life than SSD coz of the low limit on the number of read-write-cycles of SSD; but since SSD are very expensive i think magnetic HDD would suffice. and i want a portable non-bulky HDD. specifications 5, 17, 19 and 21 would be added advantages though not mandatory. i dont know about specification 6, so i request your valuable suggestions. specification 7 is of no concern to me. specifications 15 and 16 should be reasonably as high as my budget can support.

your EXPERT suggestions would be welcome and valuable to me in finding the right one. any website that allows me to choose the right product based on my choice of specifications would be much appreciated. my laptop has only USB3.0 ports and not firewire, thunderbolt, e-SATA, SCSI, etc; any workarounds for this to achieve maximum transfer speed? BTW i want the HDD to be able to connect to a USB3.0 port on my laptop and also transmit/receive through WiFi. since those HDD with built-in wi-fi antennas are costly, i am ok with those HDD with ethernet ports/jacks (in addition to a USB3.0 male connector) so that i can use the HDD's ethernet male connector to plug into the female ethernet port of my modem/router (netgear DGN1000) which has wifi antenna, as a workaround; if this HDD is also costly, another workaround maybe to connect the HDD's USB3.0 male connector to a FEMALE USB3.0-TO-MALE RJ45 ETHERNET ADAPTER which plugs into the female ethernet port in my modem/router which has wifi antenna. quite confusing ! i dont know which method is cheaper and feasible for a fast data exchange.

please refer this
and more similar stuff.

BTW is a FEMALE USB3.0 TO MALE RJ45 ETHERNET ADAPTER practically possible? i found lots of these on e-bay ranging from 1 to 60 USD. are these working for real, or just cheats? if yes, what is the maximum transfer speed achievable by this setup?
2. also is a FEMALE USB3.0 TO wi-fi ADAPTER practically possible? i found lots of these on e-bay. are these working for real, or just cheats? if yes, what is the maximum transfer speed achievable by this setup?

i was referring to stuff like these:





but, http://www.makeuseof.com/answers/usbtoethernet-adapter-network-external-hard-drive/

says it wont practically work and suggests





UPDATE 1: thanks to

for sending me this wonderful link:


UPDATE 2: since it is time-consuming for anyone to go through all this and suggest something, i have narrowed down my choices and made it easy for you; which one of these is the best? :


which is advertised to possess military-grade shockproof and waterproof


any of the 1TB USB3.0 portable HDD from seagate or western digital [which are leaders in this business for decades, though they do not have military-grade shockproof and waterproof HDD :( ]

is ADATA DashDrive™ Durable HD710 fully manufactured using ADATA parts or ADATA only manufactures the encapsulation used to cover the hard drives outsourced from other companies like seagate, western-digital, toshiba, hitachi, and sells the finished product under ADATA brand, as mentioned in some websites?

timely, expert suggestions ASAP are appreciated and welcome. thanking you in advance :)

IMO nothing short of an SSD will take harsh a use, unfortunately for the time being they are way to pricy most are 4-5 times more than a spinner.

Honesty & Integrity Above All!

IMO...you are making a simple purchase activity...more complex than it has to be :).


The reason for purchasing either an external or internal hard drive...is simply additional storage space for files. 


To try to insure anything other than that...upgrades the task beyond ihe necessary parameters, IMO.


Every hard drive is subject to mechanical failure, due to basic design/construction.  They fail...you replace, it's that simple.  And...the odds of a hard drive failing are more significant than any other component of a computer system.  Most of us have learned to live with these things and expect failure at some time.  That's one of the basic principles behind backing up routinely.


There are only a couple of hard drive manufacturers these days...Western Digital and Seagate...I believe that all of the other drive "manufacturers" now belong to one of those two companies, but information confirming or refuting that can be found using Google.


There is no evidence that anyone can provide...that will say that either Western Digital makes better drives or Seagate makes better drives.  There is advertising and there are empty opinions...but there is no evidence :).


One thing you should realize about any external hard drive...is that by adding the USB connection and enclosure, you have added two points of possibly failure that would not exist if you purchased an internal drive.  I don't believe in external drives for that reason, preferring to have multiple internal drives and extra drives for backups I routinely make.


Finally...just select the drive that you want to select and realize that there is no guarantee of anything when it comes to hard drives...the intelligent thing to do is to be prepared for drive failure of some sort, be it an internal drive or an external drive.


Buy the drive which you think is best for you :), it's really that simple.  And...read the warranties before you decide.

thank you OldPhil, hamluis for your valuable time.

@ hamluis, yeah, i admit that i am a bit overcautious about this; 1. just to make sure my valuable data is not lost (it is not feasible to duplicate ~650GB of data in DVDs; blu-ray discs are not affordable in India.); 2. to be careful not to put my money into something which doesn't deserve it; i prefer something that is worth every buck; 3. MOST IMPORTANTLY, i am basically of this type (background study, evaluation, etc.) when it comes to buying anything, and i know that i am overdoing it a bit - as you said, "more complex than it has to be" :P
BTW, coming to what you have suggested, portability is the most important need for me. so internal or desktop drives won't fit in.

anyways, i just have 2 questions to anyone reading this:
1. do those adapters (converters) work for real - to convert one port to another?
2. of what brands are the main internal parts like internal hard disk, controller etc., used by ADATA to manufacture a 'DashDrive™ Durable HD710' portable hard disk and your opinion about the life of those parts based on the brands.


URLs that answer these questions are also welcome here or in my inbox (if permissible by the BC forum rules). timely, expert suggestions ASAP are appreciated and welcome. thanking all in advance :)

to answer my own question (since there was not lots of suggestions), i settled down with ADATA DashDrive™ Durable HD710 1TB. though it may not satisfy all my requirements i had posted above, i think it is ok for me. to help people with queries about 'SSD vs HDD', a good place to start with simple explanation is




i will share more such stuff related to this thread as and when i come across.
