SSDs make a huge difference for end-users on desktops and laptops. They make that same impact on servers. That's really all there is to it.

Like whom? We use SSD and won't place more than 10 accounts per CPU core. That's no more than 240 accounts per server, I don't class that as overselling by any means .

I'm curious as to which shared providers that utilise SSD you know of that oversell. If a shared provider is using SSD, it's obvious that generally speaking they are going the extra mile and focus on performance. They wouldn't ruin that by overselling.

A lot of providers oversell with SATA/SAS, no different with SSD. Just because they're using SSD doesn't automatically mean they're not overselling.

I don't think so. I think the type of provider who cares enough to put SSDs in their shared hosting are less prone to oversell than those who have your average SATA or SAS RAID setup.

The same could have been said about some providers who switched from SATA to SAS (because SAS was the new cool thing) and they started overselling with SAS. Why wouldn't they do the same with SSD?

Anyway, I'm not saying SSD isn't better. I'm just saying a host using SSD doesn't automatically mean you're going to get better performance from them for various other reasons.

HostXNow,

Sorry but your claims are unwarranted. You cannot compare the transition from SATA to SAS to the transition from SAS (or any mechanical drive) to SSD. A 15k RPM SAS drive is about twice as fast as a 7.2k RPM SATA drive, but an SSD is hundreds of times faster in terms of IOPS. Are you saying the providers are going to hundreds of times the accounts per server? Of course not, they'd run out of CPU well before then. And that's the point, by using SSDs you generally eliminate I/O bottlenecks. End-users will definitely see a benefit.

Not to mention, if relying purely on SSD based storage you'll have a higher cost per GB and lower capacity which means there is less room on the server to oversell and place more accounts.

I think you misunderstood what I was getting at. I'll try again...

I have a clients site loading faster on our SAS setup than it did at their old provider who are using SSD drives. While the other provider uses SSD, and we use SAS, something else let the other provider down (overloaded CPU/bad network, who knows).

AGAIN, I'm not saying SSD isn#t better. All good having SSD, but other things can let the setup down.

Isn't it a given that if you have a crappy CPU or bad network, service is going to be bad?

Pretty much.

Grr, I may have gone a little off topic.

Sorry guys.

Thanks

To answer the original post: it helps if whatever you're serving would push the limits of your HDD config. It's also a big selling point in some markets regardless of the actual performance value.

If I were focusing on general shared hosting, though, I would stick with HDDs in most cases. Get some 15k RPM drives if you want capacity and speed.

SATA II with Raid-1 / Raid-10 are still really good and perform still just as good as a SAS15k but overall times are changing and we are all hopping on the bandwagon.

Personally tried SSD no real issues, are they heavily reliable, beg to differ at the moment but overall if anything I would stay on the SAS15k track.

Not sure what you mean. SATA II does not perform as well SAS 15K unless you're doing an unfair comparison of more than double SATA II drives vs the same amount of SAS.

In our fairly extensive testing we've seen no problems with reliability on the Intel drives. The newest Samsung drives seem promising too. SSD failures are often predictable and can result in a read-only state which means the data is still accessible, compared to a complete data loss on other drives. You can also use 'over-provisioning' to improve reliability (increased write tolerance) and performance of the drive.

If you do the proper research and set things up properly, SSDs are great.

Not sure why you aim to state that SSD is super awesome all the time, I think it has been established that it's surely better overall than previous disks such as SATA II and SAS15k's, I am not stipulating that SSD's are bad, we have used them and do use them within our setup as well - so we understand the aspects of it.

I am simply saying that even if you are still using SATA II or SAS15k's today you will still find sturdy performance and reliability, in our time we never had issues with SATA II ever, nor did we encounter anything bad with SAS15k - we did encounter issues with SSD's once or twice and hence why I was stating that they may have a higher failure rate but that is based on our experience.

I know you will come back with something classic to try and prove me wrong, but I am only stating from our own experiences.

thanks for this

I switch over to an SSD vps because my load usually came from mysql. I see a big change in performance (I run a vbulletin board).

If you're going to go with an SSD host, backups backups backups. Even if you're in a RAIN environment, SSDs are prone to failure.
