There are RAM-SSD modules available. Plugs in via SATA 300 or PCI or
something IIRC...
That'd be awesome for anything that needs fast IO & sustained writing.
If I remember the company Ill post here, Cheers, -Harry

Rosea,
Thanks for the replies so far. Till now people seems
to be positive
about SSD for audio data. More and/ or different views on this?
What exactly should be the problem using SSDs for audio? SSDs are far
superior in comparison to discs in every way except the the number of
write cycles.
We use SSDs in audio production a lot, also for editing video. There are
PCIe cards on the market (OCZ e.g.) which offer way higher bandwidth and
IOPs than 3GBit/6GBit SATA drives. They allow for instantenious handling
of several uncompressed HD/2k streams while editing and create a very
comfortable workflow.
Of course we don't use SSDs as a storage solution, just for the 'hot'
data (=active projects).

You may counter write cycle problems by ALWAYS USING BACKUPS-no compromise!
I used SSDs for audio recording/editing, and when you use MLC or even
SSDs with Jmicron JMF602b
there ARE problems when you dont read sequentially(e.g. multitrack), try
SSD raid or a mixed SSD/HD setup, it'll boost things extremely....
THE BIG BUT is when your SSD has firmware bugs, Jmicron SSDs are famous
for that(shows as 4GB disk), you may reflash the device(ask if you need
flashers/drivers/links), but ALL YOUR BELOVED DATA are lost.
If you need high speed access(e.g. live transmission), become aware how
cheap ram is today, and try to use something like the following command:
"mount -o size=2000M -t tmpfs none /media/ram"
No SSD can beat that...(actually)
In the end, applied correctly SSDs may speed up your workflow,
but cheap or faulty SSDs may destroy your whole contractors data.
For the money of two cheap SSD(needed for solid performance)
you may buy an old server with wnough ram slots an redundant gigabit(min
2000MB/s) and you are just fine

But the SSD will retain its data when the machine crashes, or the power goes

It'd be extremely hard to find a server that runs quietly enough for a studio
environment. I have a nice tower that was designed to be as quiet as possible.
Putting SSDs in will allow me to make it even quieter than it is now.
I do agree that having 2 mirrored drives is more secure, though.

Fragmentation can be an issue, but I guess I don't see how 2 drives
alleviates that problem. If they're mirrored, you're still writing all data
to the drives in the order it comes in. You need at least 3 drives for parity
RAID like RAID5 (which is evil anyway), so I'm missing how having a pair of
SSDs decreases fragmentation. Even if I'm writing to multiple files at a
time (such as recording 16 tracks at once with Ardour), the written blocks are
not so spread out that fragmentation would be a major issue for playback, and
overdubs would tend to be even less fragmented since there are fewer tracks
written.
Hey, linux machines dont crash as long as your

They're computers. They're going to crash. Mine do so very infrequently,
but sometimes they do.

The drummer was wandering around on a break. I have no idea what made him
push that button. When I asked him why the holy hell he'd done that, he
shrugged and said "I dunno, I wanted to see what it did." My response was that
it just added $25 to his band's session because I had to reboot the systems
and fsck the drives. (I didn't *need* to, but 1) better safe than sorry and
2) consider it a stupidity tax.) He even had to reach down and under the
desk to push it.

What I'm seeing is a significant reduction in the amount of failures in SSDs
than I saw 2-3 years ago, where an EMC storage system that had been fitted with
32 SSDs (in addition to 100 or so magnetic drives) would lose 2-3 of them each
month. By the time I left, the drives had all been replaced with newer generation
SSDs and the failure rate went down significantly - I only had to have one
replaced in the last 4 months I worked there.
Throw as many MBTF numbers that you want around; the first gen SSDs did not
come close to those manufacturer estimates.

Sorry to hear that - I'm particularly careful with my data. I back up each of
my machines nightly to a central server, and the backup partition (which is on
a mirrored pair of drives) is then backed up to an external drive. I've never
lost any data, which would be extremely embarrassing, since I'm always preaching
about backups to my clients and employers! I assume all hardware is crap and
will break sooner ratehr than later! Or, plan for the worst and hope for the best.

That's all true... Ramdisk is something to use if you're on a machine
with a UPS, a stable kernel, no xruns, etc. And you have to remember to
save your work. Still...imagine the bandwidth! Woo!

Hi,
So if you go for the SSD drives, don't go for a cheap one and backup
properly.
Do you install you Linux basesystem and home partition on a SSD drive?
Or should I only use a SSD for (hot) audio projects?
About the backups. Is a backup via network to a server good enough? It's
nice to have a fast and silent drive, but this effect fades away when
you need a other backup hdd next to it.
I was also thinking to use a SSD in my laptop, which I also use as
soundmodule e.g. playing piano with it for instance, and backup via
network. Good idea?

I just installed 2 SATA drives in my studio system to replace the 3 ATA
drives in there now: an 80 GB for the current projects and a 500 GB 2.5"
mag drive for the OS and all the non-live projects. This then all gets
backed up over the network. I'm going to pull the power to the ATA drives
today and see how much it changes the noise generated.

Certainly not a bad one, I'll be trying that myself before long even
though I don't use the laptop for music.

Which size SSD is recommended for a Desktop pc?
Do you install you Linux basesystem and home
partition on a SSD drive?
Or should I only use a SSD for (hot) audio projects?
I just installed 2 SATA drives in my studio system to replace the 3 ATA
drives in there now: an 80 GB for the current projects and a 500 GB 2.5"
mag drive for the OS and all the non-live projects. This then all gets
backed up over the network. I'm going to pull the power to the ATA drives
today and see how much it changes the noise generated.
I was also thinking to use a SSD in my laptop,
which I also use as
soundmodule e.g. playing piano with it for instance, and backup via
network. Good idea?
Certainly not a bad one, I'll be trying that myself before long even
though I don't use the laptop for music.

In my experiences, SSDs run much cooler than magnetic hard drives.
The operating temperatures for SSDs tend to match MHDs. If anything,
a system with SSDs will run a bit cooler than one with MHDs.

This is exactly how I've just upgraded my studio machine. I replaced 3 IDE HDDs
with a total of ~300GB of storage with 2 SATA drives - a 500GB 2.5" Seagate
Constellation and an 80GB Intel X25-M drive.
The 500GB drive has 3 bootable partitions so I can muck around with various
Linux distros and versions without messing up my real studio environment, and
a big partition for general storage. Working sessions are in the /tape partiton
on the 80GB drive.
I've had three sessions in the studio since the upgrade and it's been working
flawlessly, even though it's just got a 3GHz Pentium 4 as the CPU.
A side note: since these were overdub sessions, I really didn't want to be around
the corner from where the musicians were set up, since I figured that'd hamper
communications. X11VNC and my laptop to the rescue! I displayed the studio's
desktop over to the wireless laptop, and was able to sit right in the performing
area and control the transport remotely. Folks were very impressed.

I don't know whether this has been mentioned yet, but you could get a
CompactFlash card and an adapter to mimic solid state storage. You
have to look out for good performance cards, though. They're much,
much cheaper (inclusive of the cost of the adapter) than a full SSD,
and not so far away in speed.

There are some optimizations for SSD drives, and you can enable them

enabled if Btrfs is able to detect non-rotating storage. SSD is going

If you want to use all features - yes:
- You are restricted to ext4 and btrfs for the moment as they are the
only file systems that can issue the TRIM command
- you have to run the SATA controller in AHCI mode to be able to support
TRIM (and NCQ etc.)
- you should align your partitions to the block size of the SSD and
- tell your FS that it is running on a SSD ('ssd' mount option for
btrfs, don't know about ext4).
Of course you use your SSD as you would do with a HDD, but the
performance will degrade.

I use a SSD in my laptop with both ext3 and ext4, and additional mount
options: noatime,nodiratime. This is not absolutely necessary, but it
reduces the number of write cycles.
It is also wise to discourage swapping, and if you are using a
journalling system (such as ext3, ext4) _and_ everything is stable, you
can increase the commit interval.

The SSD will work fine without any of this, but it may work longer if
you add some extra options.
