SSD Raid1 vs 15k Raid10

1TB isn't very much when it comes to bandwidth. There are lots of hosts offering 10TB and more. Can you work within the limits of your setup?

I use about 250gb a month on average

Just curious: What do they charge you for extra bandwidth? That's an area where a cheap hosting plan can become real expensive.

Actually I wouldn't have a clue...there are others here using WebNX so perhaps they know:

Label says:

Are we missing something with your setup?

Oops, my mistake...YES it is 10TB...will edit post #40

 

[Gene Steinberg]

Sounds like a good deal then. We have two servers: One is unlimited, the other 30TB, but they are more expensive, and way beyond what you'd need.

no such thing as an E5-1260 6 core server ? or do they mean E5-2620 ?

 

[ibaker]

Can't seem to get anything right today...sorry but it is an e5-1650...just checked the email notification

 

[p4guru]

ah nice E5-1650 - high clock frequency + 6 cpu core/12 threads

As much as I love SSDs for MySQL/Webhosting - there can sometimes be problems using them in a RAID setup as there aren't many RAID cards that can pass on TRIM commands to the drive. Software RAID shouldn't be a problem, but that has other drawbacks.

It's not that it won't work, but performance could degrade over time as the drive fills up. Some SSDs have decent OS-agnostic garbage collection, so shouldn't pose a problem. Just something to be aware of!

Just remember that if your uptime and data is really important, buy an adequate SSD.

The Intel 320 has a great price/performance mix, the new Intel S3700 are ultra reliable SSD's for not that much money (compared to SLC enterprise drivers)

When we buy new db servers they will probably include S3700 SSD's. Extra benefit is that they use way less power then a 5-disk 15K raid set (like we have now)

Oh, one other thing: RAM is getting cheaper by the day. Look at the size of your MySQL DB and buy at least that much RAM. In theory you can run your entire DB from RAM (which is the fastest memory BY FAR).

If your entire DB fits in your RAM, then there's no real need for expensive SSD's.
