4 10K drives cannot do the IOPS of any remotely decent SSD. We're talking what, 600-800 IOPS max on 4 spindles versus 20,000 IOPS at the low end for a modern SSD? (Like a $200 one.) As far as lifetime, a decent server-class SSD should be fine. Where you draw the line between junky consumer and server-grade is somewhat open to discussion, but at least at the FusionIO end, I don't think the lifetime should be a concern. Don't let cheap SSD vendors with crap firmware colour an entire class of technology. -Michael -----Original Message----- From: freeswitch-users-bounces@lists.freeswitch.org [mailto:freeswitch-users-bounces@lists.freeswitch.org] On Behalf Of Todd Bailey Sent: Thursday, July 12, 2012 2:03 PM To: FreeSWITCH Users Help Subject: Re: [Freeswitch-users] Anyone want my SSD tips on the FS Wiki? I'm using 4 SAS 2.5 73 gb 10K rpm drives raid 5 (205 gb formatted total) on a HP P600 controller The machine boots faster that a single 64gb ssd device used briefly for testing. Just as fast, quiet, cheap, reliable and long life. Best of both worlds. On Thu, 2012-07-12 at 16:29 +0000, Michael Giagnocavo wrote:
Just as a side note for those that have not heard: Once you go SSD on your work machine, you can never go back. My Windows 7 laptop boots faster than my Android phone.

Ok been working on it all day yesterday and should be done by Monday, will post a new subject when done.
MC - I did not put the SSD into my FS Mac mini, it was another Linux machine. I spent months learning beforehand because I was thinking about it then I got a free Intel 320 160G. I just thought some of the FS folks might like to see what I did and learned. I replaced a WDC Velociraptor and this is WAAYY FASTER!

Count me in! We are using SSD in an embedded system.

Depends on what brand the drive is. We are using a lot of SSDs in a huge enterprise environment and never faced issues. On average each SSD is giving us around 2000 IOPS with a combine output of around 32000 IOPS and we will be upgrading to 32 soon. Currently have 16.
For smaller scale, I am using one in my Macbook, and never had any issues. Reaches upto 5000 IOPS and data transfer rate of around 200+ MBps. Have been using a quite a few in the servers running for FS. They work very well and never deceived. Surely, the thread is a good one, if the OP posts the draft :)
Thanks.

Or 4 million micro seconds what ever comes first.
I tried using a 90 gb ssd on linux and being curious, ran phoronix-test-suite against the drive and with 15 minutes the drive
was
non operational, rma'd the device and tried again, same results.
returned for refund and never looked back...
SSD devices may be fast but in a server environment reliability is key. currently running raid 5 across the enterprise.

I would most definitely be interested in this. I have been using SSD's for a number of different applications and never had a problem. Am I missing something? And you talk about increasing its life? Most of the SSDs I have used are rated at about 4 Million Hours which is like 456 Years (which I don't believe).
Very interested to hear what you have to say.
Thanks,
-Chris

I recently spent a lot of time learning how to keep an SSD fast and increase its life. It took a ton of research and I combined a lot of info from several sources to install the SSD. Turns out, just installing an SSD and using it as an HDD without doing anything else is not a good idea. Although the topic is not specific to FreeSwitch I am wondering how many out there would like me to put together a FS wiki page fr tuning an SSD. It's a lot of work so I won't do it unless there are enough requests or the developers want it. Mario G
