Hi All,
I'm on the lookout for an empty two-bay eSATA RAID enclosure. I'm going to stripe two 10,000 rpm disks in it, and use it for photoshop scratch.
Can anyone point me to any hidden gems? (that I can purchase in the UK?).
I'm back on eSATA now with a NewerTech MAXPower eSATA card, suggested by mrh63061 during a contribution to this thread.
By the way, I bought the card at The BookYard (good service, I can highly recommend them) and I also got a NewerTech eSATA extender cable for my Mac Pro. Easy installation, and now I've got two extra eSATA ports :-).
Cheers!
Chas

Why would you stripe 2 SATA disks to get a fast scratch drive? Good SSDs will be a lot, lot faster in both, throughput and seek time, than a striped array of two 10k disks.
The latest generation of SSDs has a read/write throughput of 270~300 MB/s per disk.* If you have a boat load of cash, you can also get disks with a throughput in excess of 500 MB/s. Seeks times will be one or two orders of magnitude faster. Depending on your storage needs (not excessively large, I guess, since it's just a scratch drive), getting a single fast SSD gives you a faster solution for the same or even less money. 64 GB SSDs start at around 120-150 € here.
* note that on some models, write throughput is significantly slower than read (sometimes by a factor 2 or 3), so make sure to check that before buying.

I don't suffer from insanity, I enjoy every minute of it.

easy answer: because I've already got the two 10,000 rpm disks.
I bought them waaaay back when we were speaking in this thread.
I had an eSATA hiccup though. That thread was written when I was still using my desktop G5. When I updated to an Intel Mac Pro, the PCI-x eSATA card of course wouldn't move to the PCI-e Mac Pro. I then bought another Sonnet card (an E2P, two ports), but it turns out that it had a faulty chipset.
I got frustrated, and just ended up using an expresscard eSATA adaptor to connect my 5-bay RAID box to my Macbook pro, and just accessed those drives on my desktop machine through my network (a huge kludge). Since I couldn't use the two Raptor drives as scratch in that situation, I pulled and shelved them, and put two more JBODs into the RAID box.
Now that I'm back on eSATA on my desktop machine, I want to use those two Raptor drives again, thus my query about a 2-bay RAID box.
Long answer, but a complicated situation :-)
I really would like to go SSD, but it'd be redundant at the moment (and I'm far from having a boatload of cash). I'll wait until a Raptor fails.
Cheers!
Chas
