Unless the firmware differs in these v. the other siblings, these have a
64GB USB Stick
2TB USB Hard DRIVE
The aforementioned, Target item, 64GB Sandisk Ultra, seems to work good for recording and time shift.
I only recorded one HD thing to test, I can't remember if it was 720p or 1080i, but did record with no issues. I lost interest in the recording quickly, like 100% of Big 5 shows.
I 99% watch record the diginets, and this doesn't seem to be an issue. Actually the USB STICK seems to work faster than a 2TB Seagate USB 3.0 external USB drive. Could be differences in the units and/or firmware since I've got an AT300 (stick) and AT263(drive).
I'd love if these and their siblings worked with larger sticks, but they tend to get pricey quick! Especially probably for the level like the Ultras.[/QUOTE]
For the iView 3500STB, the only apparent limit is about 2.3 TB, probably for either HDD or flash drives (but you'd have to take out a second mortgage for a 2.3 TB flash drive). The limitation has to do with some special NTFS protocol firmware in the disk controller that allows virtually unlimited drive sizes, but the iView 3500 STB does not recognize it, so you are practically limited to the typical HDD size 2TB drive as the maximum.
You can use a 256GB SanDisk Ultra Flash Drive (SDCZ48-XXXX-256) in an iView 3500 STB. A couple weeks ago, you could have bought it on sale for $60 at Best Buy, they typically sell for $70 on Amazon. That's not a bad price considering how much more the SanDisk "Extreme" costs, or the fact that just a few years ago, that was the cost of same size HDD!
I DID run into a weird problem with my SanDisk Ultra drives, not sure what's going on. This doesn't have to do with the iView, but rather MOVING files from the drive to a PC, perhaps in conjunction with USB extension cables, maybe having something to do with having previously renamed the files using the PC.
In any event, I was moving files around, renaming them, and I noted that I could move about 20GB in less than two minutes, which is tantalizingly close to the package claim of being able to "transfer a full-length movie in less than 40 seconds*" (NOTE ASTERISK, TYPICAL PHONEY FLASH DRIVE PERFORMANCE CLAIM NONSENSE).
But then I just wanted to move (by cut and paste) about 20GB from the SanDisk to the PC, and IT TOOK LIKE TWO HOURS OR MORE!!! WTH!!! Then it happened again...
Same flash drive worked fine in the iView later, so I really don't know what happened. I do know that the SanDisk Ultra drives will typically pop up a message on the PC about "corrupt or missing device" when I plug it into the PC, but it typically doesn't make any difference for actual operations, everything seems to work fine...except occasional VERRRRRRRRRY slow transfer speeds...
Maybe because these drives have been formatted on the iView? I don't know, I hope it doesn't have to do with extension cables, I really NEED those for the Ultra...but more "fun" figuring it out...
