Buying a 6TB disk in the UK

7 posts in this topic

I'm looking for a 6TB disk to fit in a small home server, it's not a RAID configuration. I use it as a development database server, so it works hard. Performance is fairly important, but moderate power consumption also desirable.

Availability of 6TB disks in the UK is currently limited. I'd prefer to avoid buying from overseas. The only one offered by my usual supplier (Amazon.co.uk) is the Western Digital Red 6TB. This disk is designed for use in home/small office RAID arrays and NAS systems, but are there any reasons it would not be suitable for my use ?

Alternatively, would anyone like to guess when the other 6TB disks available in the US will become available in the UK ?

It's not a performance drive is your main concern. I'd guess the HGST He drives are available there, but the high price is a problem...then again, you get more performance.

I think you're right that the Red might not be fast enough. I'm currently using a 4TB 7200rpm Hitachi drive, and a get annoyed waiting for that to complete database operations. I guess I will have to wait for some consumer-priced 7200rpm 6TB disks to arrive here.

There's always flash for some of the smaller but more used DBs...or caching.

I second that an automatic flash cache of your current hot data in the database is probably the way to go. Any 7.2k rpm HDD will still feel very slow in comparison. There are some dedicated Cache SSDs, or if your mainboard allows you might be able to use Intel SRT. Or maybe the database software itself offers caching.. that could be really smart, but they might charge an arm and a leg for it.

If you're already feeling slow with a 4TB 7200rpm disk... yeah, it sounds like you're going to need something faster. A two-disk RAID1 might help with reads, but it's not going to help with writes. I assume going SSD or at least SSD for cache is not realistic?

Try and hold off a few months, there should be better availability of bigger drives.

But, as others have said, you really want to be using a SSD for the DB stuff and just use a spinner for your big 'slow' data.
