Need input on an external Hard Drive

post #1 of 7
Thread Starter 
I found this external HD and was wondering if it was a good deal.
http://www.zipzoomfly.com/jsp/Produc...tCode=10006963

or

Should I just buy and enclosure like: http://www.newegg.com/Product/Produc...82E16817145132
and just slap a WD 320 AAK into it.

I'm just trying to find the best way to spend my money on an external HD. I shouldn't need any more than 320gb of storage but 500gb for $100 seems like a good deal. Any suggestions on other externals are welcome. Thanks in advance for your input.

Do you have a esata port on your mobo?
If so that is the best way to go.

I had a WD external drive used with USB, and it was really really really slow.

I have seen on forum such as fatwallet or slickdeals that bestbuy is clearing out the Hitachi 1TB external drives for 127 or so, but always with Bestbuy clearnace it is YMMV.

I would recommend buying your own HD and a separate enclosure--because there's no way to know whether the physical drive in external HD's are of good quality, or bottom-of-the-bin (so to speak...). At least you'll have more control on the performance qualities of a HD you buy and put into your own enclosure. It's just that I bought two external HD's over the years, and both have had catastrophic hardware failure with relatively little use (as opposed to HD's constantly being used inside a computer), but any individual HD I buy and put into an enclosure has never had a problem (yet...). Just my suggestion. Don't worry about the price/GB, worry about the quality, especially if this is going to be your backup drive.

1st priority - interface. The speeds are:

eSATA (300 MB/s) > 1394b (40MB/s asynchrynous) > USB 2.0 (48MB/s synchronous) > 1394a (very slow) > USB 1.1 (unusable)

eSATA is obviously the fastest, as it lets the drive run as if it were an internal drive, and you can most likely even RAID two eSATA drives on the same controller.

Between firewire-B and USB 2.0, you'd think that USB is faster right? But thats not the case. When you use a USB drive, all commands have to be "acknowledged" by the device. Kind of like a "ok the packet was good". With firewire, the computer just floods information to the drive and only backtracks if the drive says "hold on I missed something". With the extremely low rate of errors (unless you have some wierd situation), firewire-B wins.

So pick the fastest interface you got.....and if its not eSATA, the specs of the drive don't even matter (other than size), as the interface will be your bottleneck. And for the record, I've heard of a lot of cases of those WD external drives overheating in their fanless cases, so get one with a fan.

I don't have any esata ports on my MB, but I've seen some inclosures come with esata brackets. Do these brackets just plug into a regular sata port giving you an esata port? Here is a link:http://www.newegg.com/Product/ShowIm...rnal+Enclosure

And for the record, I've heard of a lot of cases of those WD external drives overheating in their fanless cases, so get one with a fan.
Actually, I don't think the interface matters much for performance. This is because current drives only have sustained read/write speeds of maybe 60-70MB/s. And to correct, USB 2.0 has a constant transfer speed of 60MB/s (480Mb/s). So having a faster interface doesn't matter 'cause USB 2.0 is about as fast as a current HD needs to operate at it's normal read/write speeds, since no single drive can read/write at 300MB/s in the first place--even two RAID0 drives won't transfer that fast.

I'd suggest using what's most universal--in this case, USB. 'Cause if you wanted to transfer files to another computer or laptop (especially older computers), you might not have eSATA ports on those machines, whereas USB is fairly ubiquitous.
