I bought a Plumax PM-525C2-PPS V4 Silver Combo USB 2.0 & Firewire 1394 External Enclosure for 5.25 / 3.5 Inch HDD/Device, w/ Ball Bearing Fan & EMI Shield from DealSonic about 6 months ago, and promised a review when finished. I see that they are still selling it as well (Part#:DSPMX525C2PPS) I have a laptop and bought the NEC 3520A for it. My P3 1.0ghz laptop only had a USB1.0 port, so I have used it almost exclusively through firewire.
Quick summary: flawless operation. I’ve burned/copied/shrunk countless video DVD’s, regularly use DVD-RW’s for backups, burned audio and data CD’s with absolutely no failures outside a few stupid errors on my end (like accidently unplugging it while it was writing) - not one unexpected coaster. It burns in all modes without any unexpected buffer runouts. I’ve burned data and audio CD’s up to 48x without a hickup (didn’t have faster media). I’ve done variety of DVD video copies - both raw, via dvd decrypt, and dvd shrink. Burned DVD videos, burned DVD ISO’s, at 8x and 16x without a problem. I’ve copied a number of dual-layer video and data DVD’s (2.4x), and regularly use DVD-RW’s (8x) for my backup purposes. I think I’ve used all the different modes and speeds possible on this drive - all without a hitch.
Physically, the case has held up very well. The plastic hasn’t scratch or cracked that I can see. You can tell this isn’t the kind of case that will take a beating or dropping, but with the drive in it; it is very solid and the fan - while not silent - is very tolerable but really does a great job of keeping things cool. It’s got just enough design not to look plain, but not so much as to look tackey.
Overall I have been extremely happy with this case - it works so flawlessly that it’s transparent. I just plug it in and go for any operation. Absolutely great performance and no unusual behavior. My performance characteristics are as good as any of the internal/desktop installations.
In short, if you want a great USB/Firewire external case for an excellent price ($29.99!), go no further than this guy - you can’t go wrong.
Hope this helps. I’m returning the favor for those who helped me pick a case. Post here if there is something specific you think I should try (I probably have but just forgot to put it up
