Data recovery and disk repair questions and discussions related to old-fashioned SATA, SAS, SCSI, IDE, MFM hard drives - any type of storage device that has moving parts

If I understood it correctly, the difference between PC3000 Express and PC3000 UDMA is Speed and the number of HDDs that each solutions can attend simultaneously. Is there anything else that I should know of ?
Is there any other tool that has the same functionalities and availability of manuals, but without te furstrating Wait time that Acelab is imposing on its customers ?
Thanks for any info

and pc3000 express works on 64bit systems I think.
UDMA doesn't.

UDMA is now becoming obsolete.
Ace imposes all clients to upgrade to UDMA-E.
As far as I know, support for UDMA will end in 2015 or so.

as northwind said, go for pci express,
becouse UDMA has got still 2 years of updates, than will be obsolete, but still working of course.
pci express and udma has got same functionality, only speed is 2x faster and os support to 64 bit.

The main difference:
Eхpress - 4-channel PCI-E and 4-port SATA (or 2 SATA + 2 PATA)
Tasks for each port is not dependent.
UDMA-E - 1-chennel. but 2-port SATA (or 1 SATA + 1 PATA)
dependent tasks.

UDMA suport is schedule to end in January 2016.
But I suspect that with MRT competition it may end sooner.
Right now prices on the Express are high, hopefully the will drop a little in the future.

-BR-,
Hardly the price drops.
Actually Excpress replaces 2-4 Udma-E.
So buy it more profitable than a few udma-E

einstein9,
To each his own.
Saves space, do not need a lot of computers.
Tasks for each channel are independent.
If one hangs, others work.
In contrast to the PC3k-PCI, where hung all tasks.
DE runs and regular discs connected not only with the controller.
Simultaneity can run many tasks as there are free ports on the PC.
For one master Express is very convenient.
