The answer would normally be to use ExFat, but 10.5 is probably too old to support that.
You could instead try something like Mac drive…
Also, if you don’t need any sort of performance, then there are free FUSE based solutions for Mac that allow you to read and write NTFS, but that can be slow.
Also you could probably just use FAT, which will probably work on both already. However, this has all sorts of limitations and would not be my choice.
Another approach would be to purchase a NAS of some kind. The you’ll have shared storage that can be accessed from all of your systems without these sorts of complications 😉

So what you’re really describing is a shared storage server, not direct attached storage…
Unless you’ve done this before you’re unlikely to get the kind of performance you need over the network.
To actually answer the question, the LSI 9361 is an excellent card, I work with them all the time. They perform very well, but MegaRAID Storage Manager is atrocious – hate it with a passion. Areca have better management software in my book, but the performance isn’t really all that different between products at that level.
NB: As above, the 9341 is probably not for you.

I was going to reply to this a while ago, then got sidetracked.
Hopefully you used drives from the Areca HCL.
No idea how big your volumes are, but maybe try making two smaller file systems on top of the array and see if you get the same slowdown when they start to get full. Sorry but thats the only thing I could think of trying, other than returning the card for a replacement… FWIW Its not beyond the realm of possibility that the card is faulty, although I’d assume you’ll have some logging somewhere (just not sure where this card puts is on Windows).

The ANT2 looks like a 4x drive Supermicro/Ablecom chassis. We have used them at indiestor, but generally supply 8x minimum.
You’re welcome to drop us a email if you’re based around London. We’re a small shared storage specialist based in Kent.
Our own server solution runs a conveniently simple user/workspace management software (indie-pro), which is really easy to get to grips with. While we mostly deal with rack servers, you can also have a super quiet tower version of our 8x drive.
I can probably hook you up with a demo box in the new year, if that i of any interest. Everything we do is 10G equipped as standard. We have heaps of customers in and around the UK (Attaboy, Knickerbocker, TheFinishLine etc)…

Then in my opinion Evo, Pro or similar will be fine. You’re unlikely to kill them as a single user. If they slow down secure erase and start over.
Generally the more expensive (pro/enterprise) drives have better IOPS figures, which is less important if you’re just doing sequential reads/writes… maybe more so as a cache drive for lots of little bitty files.
Pretty sure there aren’t RAID specific SSDs (would love to see a link if there are). HDDs yes – TLER and such + designed for density/vibration sensors etc etc… SSDs though I’m not convinced other than the logic that enterprise class drives are probably going to have a better MTFB rating.
Actually I don’t think you can screw this up.
As above, the weakest link will be how you implement the RAID. OS X + Windows have crap offerings OTB, unless you use a hardware based controller from LSI/Areca/Adaptec etc.

My question to you would be how you handle the RAID side of things?
I don’t know of many (RAID aware) filesystems or hardware RAID implementations that can properly TRIM SSDs… Normally you have to rely on built in garbage collection. Happy to be wrong, but fairly sure I’m right.
NB: ZFS on BSD can issue the command to the underlying devices. Don’t think ZOL can do it (yet).
Things to think about:
* In the real world we found that SSD based ZFS (ZOL) pools don’t really slow down when writing large files. Point in case, we have compact 1U indiestor servers on a fleet of OB trucks. As yet there has been no real need to secure erase.
* I don’t know of (m)any SSD’s that are built with striping in mind. There are however enterprise grade SSDs that are SLC based (not MLC). They usually have caps for retaining data in the case of an unclean power down (makes them suitable for cache devices in certain types of storage pool). These products tend to have a greater endurance rating too.
* FWIW my experience has been that the endurance of even lower end MLC type SSDs (Samsung Pro etc) seems to be remarkable.
To conclude, I’m not sure how much this helps, but ostensibly it seems that no – I don’t there is no such thing as an SSD that it setup for striping, per se.
IMO just get one big/better quality/higher IOPS SSD and back it up.
Thats my view.

Finally! This is a good move. I hope they test it thoroughly and get the bugs out though.

They have a rich feature set, but IMO this is probably just another one of those special clubs for people in the know.
F*ck Cisco for shared storage, frankly.
Like everybody else here I’m basically smitten with the Netgear XS range.
Oh and my best kept secret is the DLINK 1510-20, its a champ if you need 10G uplink, but only gigabit to the desktop. Of course you could just go direct, depends what you are doing. For 170GBP you can buy one for an experiment and its not going to cause any heartache.

Pretty certain GB don’t have an option for native AVID sharing.

Of the three I’d go with DDP.
They build products are actually designed for video storage.
Bob will be along to tell you more about this in a moment, but trust me – you need to get in bed with a storage company that understands the ins and outs of what you’re doing.
Short answer – but probably the right one.
