That's simply the maximum burst throughput range of SATA2 (original SATA was 1.5gbps). There is no way that a single disk can deliver that throughput.
My testing (YMMV) is that eSATA will give you about 1.5x the speed of USB2 Cheers Ken -----Original Message----- From: Eldridge, Dave [mailto:[email protected]] Sent: Thursday, 17 September 2009 12:32 AM To: NT System Admin Issues Subject: RE: Disk based backup You would think esata throughput would be much better. I am looking at a promise tx4302 pci card that specs 3gb/sec for esata. This is for both the internal connectors and external. -----Original Message----- From: Erik Goldoff [mailto:[email protected]] Sent: Wednesday, September 16, 2009 8:20 AM To: NT System Admin Issues Subject: RE: Disk based backup But now wouldn't eSATA be a good alternative ? I haven't benchmarked throughput but *should* be as good as internal, right ?

LTO4 alone should get you 5x-6x the speed of a USB connected drive (YMMV) Cheers Ken -----Original Message----- From: Benjamin Zachary - Lists [mailto:[email protected]] Sent: Wednesday, 16 September 2009 9:14 AM To: NT System Admin Issues Subject: RE: Disk based backup Why not just take some external drives and mount them in whatever you use (BEX/UB etc) and rotate the drives. At 79 bucks for a 1TB SATA, or 89 for a USB version, you could do a 5 day rotation for 2 weeks for 900 dollars if you can get the data on 1tb. If you want to be more involved do the backups with deltas so you only do changes throughout the week and should be good. With the drives being so fast restoring through 3-4 usb drives isn't really a big deal, not like waiting 30 mins for cataloging a tape.. ~ Finally, powerful endpoint security that ISN'T a resource hog! ~ ~ <http://www.sunbeltsoftware.com/Business/VIPRE-Enterprise/> ~
