Hello all, I read your post with interest Mta. I was quite astonished by the disc image backup speeds you were achieving.
My machine is quite old now, but serviceable. I thought I would do an experiment to hopefully add something to the debate.
I downloaded the Macrium Reflect product (free) from their website. I had just performed a backup using Paragon Backup and Recovery Free version that I generally use.
I did two Image Backups using Macrium to an external USB 2.0 IDE disc. The first was with the default medium compressed data, and the other with the maximum compressed data.
The comparison with Paragon is not entirely fair as the Paragon image backup was performed with the same source disc, a little earlier granted, but to an internal SATA drive. This backup one would have expected to be much quicker given this advantage. This was necessary because of the availability of backup space. The results however speak for themselves. The backup I took with Paragon was with their maximum compressed data configuration.
After a disappointing start with Macrium, largely caused by user error:
(I forgot to remove the backup drive from the list of drives to be imaged. This immediately resulted in the error: “MFT corrupt - Error code = 6. Please run 'chkdsk /r'” from Macrium. Sadly this resulted in me running chkdsk on both drives to no avail, a pretty long winded process, and a reformat of the backup drive. It was after all this I realised what I had done wrong. In minor mitigation, the error is somewhat misleading. However, having said that, I throw up my hands and exclaim “it’s a fair cop!” to the deities overlooking data backup. )
System Data:
Intel Pentium D 930 dual processor clocked at 3.45GHz.
4 GB installed RAM (clocked at 235MHz). ASRock Motherboard with RS400 Chipset.
Source Disc IDE Drive system disk ATA UDMA (mode 6)
Destination disc for Macrium test: 320 GB USB 2.0
Destination Disc for Paragon test: internal 500 GB SATA ULi M1573 SATA Controller.

So, it looks like Macrium Reflect is much quicker, but produces a marginally larger disc image. The differences in speed are just not comparable. Macrium is the best part of twice as fast.
The Macrium interface is less cluttered. Things are more obvious, although it did catch me out as indicated above.
I don’t have figures for a Paragon backup uncompressed, or indeed their version of medium compression.
A Few questions:
I cannot yet find a way to restore individual files or folders/subfolders from a disc image. Is this not available in the Free version of Macrium? It is in the free Paragon product. [Edit2: yes you can! see p200 of the pdf user manual]
One of my hard drives has a red bar indicated in Macrium I think indicating how much data is on the disc. I had a look at the manual but didn’t find the information. The fact that it is marked in red concerned me slightly, or does this just mean that the disc is near capacity (425/465.78GB)?
My firefox browsing history was no longer available after the Macrium backup, have others had this problem or is it just a coincidence?
[edit1: i found the file places.sqlite.corrupt in my firefox profile file alongside places.sqlite. I replaced the latter with the former and my history returned ( at least to last night). This .corrupt file was timestamped at the time the backup was running. Perhaps this was as a result of the backup going on at the same time. I just had a quick web-browse during the backup!]
I hope this information proves useful.
