We’ve been running on a rented root server. Now we want to roll our own hardware and can therefore choose the ideal components for running AS with a very write-heavy application. Ofc we know everything that has been said in the docs about the matter. However, we haven’t really understood yet what specs we should watch out for when it comes to IOPS.
So a general question: What is the most significant metric when selecting a model? Sustained 128kb (=write block size) write IOPS // 128kb random write bw or even 128kb sequential write bw ? (a.k.a. “What is the bottleneck with writes with AS”)
And a particular one: Does anybody have experience with running on the 845DC PRO? It’s specs are kinda promising:
- Enterprise/data center drive (10 DWPD for 5 years)
- 50,000 4kb write operations sustained - not sure if 4k perf is important with AS
- SATA3 (easy scale-out; pack more than 2 in a node)
- Latency seems to be ok too (avg 0.5ms, max 13ms, source: TheSSDReview.com)
- it became very cheap in Europe (~560 USD for the 800gb model)
It seems to be similiar or even better (33% more write IOPS) than the Intel S3700, but comes at half the price tag of such a drive.
Because our budget is limited, we would like to know in advance if there is any issue with this device before spending 600$ on atleast 1 drive to run ACT on.
Ofc we will run and publish ACT results once we purchased something.
