that's not really what makes it an AV drive.

An AV drive is designed to IGNORE data errors, whereas a 'normal' hard drive will attempt to re-read/re-write problem sectors for a set period (up to 15 seconds, depending on the drive) until the internal checksums shows the data is consistent. For a desktop drive this is what you what - it makes sure the drive stores and recalls the correct information. However as the drive is unresponsive for the retry period, it could cause a blip in the video if used to record an AV stream. As a result AV drives ignore any errors and just keep going - a small artifact in a video is preferable to a break in the stream. Such an error could have a huge impact to system stability if it occurs in an OS file though, or it could corrupt a photo or other document and render it useless.

Now you will probably never see these issues, at least while the drive is new. But they are not designed for use in desktop (or 'normal' RAID) systems as they can corrupt data. This is the reason why manufacturers make enterprise disks and video disks - the drive may be the same, but the error-handling firmware is different.

It will be fine, it is designed to have data constantly written so it should last a long time in a PC

Showing as 'Out of Stock'

Temp out of stock.. Cracking price though.

Good price but it's an AV drive. Not designed for your typical desktop storage although it may well be fine.

seagate :disappointed:

I don't get why they have a version specifically for surveillance, what would be the downsides in using this as a NAS drive?

Useful in a server (or NAS) setup - cracking price (if it actually ships).

Great spot. Don't think I've ever seen 5Tb at that price. Heat and ordered!

EDIT: Actually after reading lilbeastie's comment I may cancel as I was planning to upgrade my desktop HDD. Will think about it -
can always cancel before it ships I guess.

Totally agree. This is not suitable for 'normal' use.

£201 now

Great info. With this in mind, would this make this suitable to store and replay video in a server using Plex (OS is on SSD)

Thank you that's helpful got an order in was expecting a cancellation notice now will have to think about as was planned for a data drive to back up videos, music and photos. Not operating system or apps in a server. Plex really. Not needed yet but the price was really good have a data drive with no recent backup so balancing that risk. Problems of growing data. But thank you OP.

Yo Frank!! Welcome back buddy.

Thanks for the PM Frank :smiley: Got mine for £73.40 using your code

define "suitable" - it will do it, but it's not really the right tool for the job. In practice you're unlikely to ever see any issue if you just use the disk to store video files for playback though. It'd probably be fine for ripped discs or similar that you can re-obtain relatively painlessly, but I wouldn't use it to store your wedding videos unless you have another decent backup or two elsewhere.

Now backups is a whole different story too... :smiley:

So no good for storage for movies and music?

Expired now; no longer able to buy from Amazon.

Fortunately I am after a dedicated surveillance drive as I am using an old sata2 samsung for now and that isn't really suitable.
Thanks for the info.
