Linkstation Quad LS-Q6.0TL/R5

Question about replacing a failed HDD...

Have been using a 4 x 1.5TB Linksation Quad (LS-Q6.0TL/R5) for 3/4 years now. In the main, pretty satisfied with my Buffalo product, which is used to stream lossless music content on my Sonos system. Until last week, where my Disc 4 is flashing red on the unit. I'm, getting the warning:
E13: Error has occurred at RAID array 1.
E23: Disk 4 is removed from RAID array due to errors
Information
I1.2 The RAID array works under degrade mode.

I guess it's terminal for Disc 4 and I am resigned to having to buy a fresh disc. No real problem with that, its served me well and well used tech things don't last forever!! Data appears fine for now and accessible etc, but obviously no RAID array means that I need to replace ASAP.

My problem is that I am finding difficulty in sourcing a replacement disc. According to stuff I can see online, I should be sourcing a OP-HD1.5T (according to http://www.buffalotech.com/pop-comparison-chart/replacement-hard-drives).

But I just can't find an online retailer that supplies that drive. Where should I be looking or is there an alternate Buffalo drive I should be replacing the goosed Disc 4 with?

....or have I bought a Pig-In-A-Poke product as a NAS Drive....

BTW, I'm based in the UK if that makes any difference.

Pretty much when buying a disc you can hunt down the same model of the disk that died or get another hard disk around the same specs and size. No point in  buying a 3TB disk if you dont have all the disk at 3TB.

Thanks joma90, so I don't *need* to get a Buffalo branded, OP-HD1.5T disc, I just need to get one that has the same spec as a OP-HD1.5T drive? And generally fits what the Linkstation Quad is looking for?

If I can't get a 1.5 TB, then I guess I have to upscale to a 2TB (albeit that the additional ~500GB may be under-utilised). If I drop down to a 1TB, then I will be compromising data and/or the RAID structure.

Sorry for all the questions, but a bit of a noob when it comes to this. The product has done me well since I installed it and this is the first bit of serious mainteance/replacement I have had to carry out.

Cheers

Correct. It has be at least be the same or greater. Going lower will slow down the performance. :D

Correct you cant go below 1.5TB because your raid is with 1.5TB drives. You need 1.5TB or 2TB. If you get a 2TB. You wont use 500GB of it. Since the raid was not build with 2TBs.
