Ask HN: Cheapest way to store 6TB online?
What is the cheapest way to store 6TB of key-value data online?
The data is accessed via random lookups and needs to maintain <0.5s service times per lookup and can expect around 200 concurrent accesses at any time.
It's currently hosted in a small Cassandra cluster and that gives lookup times of 15ms-20ms, well within acceptable limits. However there's no reason it couldn't be moved to another indexing system (it could even be moved to a suitably tuned filesystem with little effort).
- NarwhalAttacks 14y agoIf you are near a larger city, I would look into colocation hosting. Buy the hardware up front, and get some big disks. RAID or ZFS for redundancy.
- e-dard 14y agoI haven't checked, but I would think Amazon Glacier, assuming you only need to long-term archive the data.
- mattbillenstein 14y agoPerhaps you missed the "< 500ms request time and 200 concurrent req/s" part of it??
- bockris 14y agoDid you even read his post? This is a key-value DB that he needs 1/2 sec response time to. Glacier is primarily a 'vault' type service where your access time is measured in hours.
- e-dard 14y agoNo! This crappy iOS app has a glitch and only showed the “cheapest way to store 6TB online” part! That’s amused me somewhat chuckles
- mattbillenstein 14y agoHow big are your objects? 6TB in AWS S3 is about $720/month ...
- cmer 14y agoSeems like Hetzner might be a great fit for you: http://www.hetzner.de/en/hosting/produkte_rootserver/ex4s http://www.hetzner.de/en/hosting/produkte_rootserver/ex4s 60 euros buys you 2x3tb of storage. It's raid 1 but I guess you could ask to have it raid 0.
- NarwhalAttacks 14y agoRaid 0 on 6TB is a terrifying prospect.
- 3amOpsGuy 14y agoThanks all for the leads. Hetzner are seriously low priced, impressive. In the end we've gone for co-location, we tried to avoid this due to the hassles we've had in the past around physical access. I guess this workload isn't a great fit for the cloud just yet. Maybe some day!
