33 This first one is like the one that doesn't work.  Of the three, two
34 didn't work correctly and the one that works without errors isn't that
35 fast either.  I wouldn't recommend this one unless something has changed
36 which makes it much faster in the case of the one that works and is
37 dependable in the case of the two who doesn't.
41 This next one is the one that works great.  It's fast, every bit as fast
42 as my internal drives.  I have not tried the USB port so I'm referring
43 to the eSATA port only.  Let's hope they haven't changed this since it
44 works great.  The display is hard to see on the main image but another
45 image shows it well.  I might add, the price has went up quite a bit
46 too.  o_O
50 One other note, neither of those are the vendor I bought from.  The
51 original vendor had sold out and either unlisted the item or no longer
52 had all the info. 
54 I'm sure there are others out there that work fine.  I'm just sharing
55 the ones I have that don't work right and one that does.  Just like hard
56 drives in general, I'm sure others will have different experiences.
