Although I'm not really sure what you mean by `via ISCSI' (a scsi transport?) iSCSI is kinda like ATA over ethernet, it allows you to "attach" a disk to a system, over the network, but have it appear like a local disk. For example, I have a windows 2003 domain controller that doesn't have much space for storing roaming profiles etc. So I attached a disk to it via iSCSI (in fact it is only a ZFS dataset, not a whole disk), windows sees it as a local SCSI disk and lets me format it with NTFS and use it for local storage. try http://en.wikipedia.org/wiki/ISCSI Your list email address looks like it might be a phony (I didn't try it) but mine isn't so if you don't mind the personal contact please let me know and I'll write direct.

No, of course not, and what's more it denies you the fun of getting another gizmo working, but for simplicity it's hard to beat. For my purposes, anyway. -- Rgds Peter

Have you timed any thing like write speeds across the network to this box? Is it connected into 10/100 or 1000 (gigabit) setup? I meant to say in my last message that IIRC you're never going to actually achieve "gigabit" speeds. If your motherboard lacks an onboard gigabit card then you're limited by the PCI bus, and I don't know that most drives can even write as fast as gigabit. AFAICT one tends to use gigabit at present because it's "faster than 100 Mbit/s" - one would probably be happy with 400 Mbit/s or so, but if you've never used NAS or network storage before then in general old 100 Mbit/s ethernet is plenty fast enough for most people. Copying 700mb across old 100 Mbit/s ethernet only takes 2 minutes (I should add this is from a slow old PIII 700mhz "NAS" to my dual-proc G5 Mac with 3gig RAM & SATA; copying the same file to the same disk on the G5 was less than 50% faster). Stroller.

I only tried a few tests and they weren't done rigorously like someone benchmarking would have to do. I made no attempt to control what else might be running, other than not purposely starting anything. I tried copying 950MB of graphic files across gigabit lan (winXP to the Book) ... it took 3 min 40 seconds. (about 4mb sec) Whereas copying the same data from one machine to another (windowsXP) took 40 seconds. (Incidently.. that appears to be a bit faster than what you report at 23mb sec) Might have something to do with the fact that it is identical filesystem to identical filesystem (ntfs) Copying the same data from a winXP to my gentoo box across 10/100 lan took 1 min 10 seconds. (A little less than what you see at 13mb sec) So even in a case where the measurement should have been skewed in favor of the Book, it was over 300% slower. And in the case that should have been comparable it was over 500% slower. Unless I've made some horrible error in the math, which is not unlikely, I think my test shows 4mb per second. (I just divided the MB by the seconds), that is so far under what you see, that alone tells me to return this dog and spend the money ($229) building up my own.

NFS read is about 30-34MB/s, writing is considerably slower with 15MB/s. So writing is a bit slow. But as i do not need fast storage i did not investigate. And it must be mentioned, that the whole data is in AES. I use this share like a local harddisk. There is nothing like "Oh, this is on remote storage, i will do differently." I do everything i do on a local disk, and i did not find anything that would not work due to lack of performance. Admitted i do not do much performancecritical stuff.
