Actually with my Accelsior the boot time increased significantly from booting off a single SSD in a standard drive sled. It must have something to do with it being in a PCI slot.
Hah!!! Where have you been - I've been wondering for ages why I couldn't get the darn AJA test to run on my RAID0 boot drive.

Boot time with Solo x2
I have submitted this problem to the technical support from Apricorn and they do not have the solution.
It is regrettable that boot time with Solo x2 is more slower than the native SATA II, about 10 second more slower with Solo x2. My boot disk is however well selected through system preferences.

I've seen the same, and it seems to be the added time the mac takes to scan the PCI bus - see the bootable SATA controller and then whatever time the X2 takes to scan/check the drives before the booting starts. (if you boot this thing up in windows, you can see the bios-boot info that the X2 throws up displaying attached drives, etc.)
I don't think there IS any real way around this with the X2, although boot times were not something I felt like I needed improvement on so its not bothering me.

That's great you finally got this sorted... and respectable performance.
Q: (for anyone) has there been any issues or delays resuming from sleep?
It's more of just a curiosity for me. I leave my Mac running 24/7, so it doesn't really matter much to me.
I let mine put the monitors and the drives to sleep but I don't let it put the pro itself in sleep mode - I haven't had any trouble but I'm assuming that's what you're really asking about.
I put my MP to sleep when I'm not using it... I just wonder if the machine has trouble waking from sleep when the system drive is on one of these cards.
Ok with the Intel 520 240GB SSD as boot drive on the x2 only got:
write 451 MB/s
read 467MB/s
Speed limit of the Solo x2 in current use
While this Solo x2 card announces transfer rates up to 550MB/s in both read and write, I doubt a single SSD SATA III will ever reach 500MB/s in sequential read with this card.
However, a Crucial M4 128GB can easily reach, since the firmware update build 0009, the 500MB/s in sequential read with incompressible data.

I have not seen a case on this thread, a single SSD approaching the 500MB/s in sequential read, specially with incompressible data.
In fact, I'd be curious to know how fast this Solo x2 saturated with sequential read and write with incompressible data. I doubt it will ever reach 500MB/s and 400MB/s in read and write.

Depends on the options and test settings and how full the drive is. My OWC 6G which is slower just got 503 Read, 483 Write. The speed of the 520 is much more about the balanced firmware and iOPS and response and fast 4K writes. You wont notice 467MB/s vs 500MB/s anyway really.
The nature of the data (incompressible or not) will not impact Read speeds on SSD's. That will only affect write performance and only on SandForce-based SSD's.
Almost all current gen SSD's can achieve 500MB/s Reads on SATA3 (M4, 830, 520, Vertex 4, etc.) so we would expect them to perform to that level with this card. However, as you point out, many are not, so it's possible there is some bottleneck on the card, the PCIe bus, or the way Intel handles it in the ICH. And the bottleneck is even more apparent when you connect two drives in RAID0 to this card.
So far the way to ultimate performance seems to be to buy two of these cards, use a single SSD on each, and RAID0 the pair. Member allYcad was able to achieve 1GB/s Read's this way

En effet, tu as parfaitement raison. Le traitement des données incompressibles affectent celles en écriture et non celles en lecture. Quant aux SSD les plus touchés par les données incompressibles, ce sont ceux qui sont dotés d'un contrôleur SandForce, comme tu l'as si bien souligné.The nature of the data (incompressible or not) will not impact Read speeds on SSD's.

Cela dit, je doute fort qu'un seul SSD via la Solo X2 puisse jamais atteindre les 500MB/s en lecture. C'est une bonne carte mais elle ne remplacera jamais le SATA III natif, comme chacun sait.

C'est ce que je pensais aussi, mais allYcad a posté ses repères montrant une paire de Vertex3 atteindre 1000+ MB/s en RAID0
Allright you guys, I got TWO of the Velocity Solo X2's and configured them with TWO 120GB Vertex3's, RAID0.
I then used DiskTester 2.4.0 64-bit and ran the sequential-suite test.
I've attached the full report.

Et ton OWC Mercury Accelsior PCI Express SSD 480GB, quelle vitesse réussit-il à atteindre en lecture et en écriture avec l'application Blackmagic Disk Speed Test? Je pose la question parce que j'aimerais savoir comment il assure avec les données incompressibles.

Can you do an AJA test on that? I'de like to compare it to the performance of my Accelsior, but I don't want to buy Disktester to do it. I suspect that many of those numbers you got will be much higher than the AJA test.
I'm from the US, of course not. We are terrible historians and only teach our children that everyone else is inferior
But I do now. Thanks.
My comment was more Quebec vs. Ontario vs. BC. Which socially is still very much an issue. It was also very tongue in cheek.

Several posters in this thread have mentioned that the Velocity Solo X2 will not boot in a 2008 Mac Pro 3,1 computer. Checking the Apricorn web page for this produce seems to indicate that it does boot on a 2008 Mac Pro.
Is this something that has recently been upgraded?
http://www.apricorn.com/products/desktop-ssd-hdd-upgrade-kits/vel-solox2.html
MAC PRO
The Velocity Solo x2 will function in all Mac Pro models, but will only boot in EFI64 machines which are the last 3 models known as Mac Pro 3,1 4,1 and 5,1 Your Mac model can be found by doing an "About This Mac", and then "More Info". The first two models known as Mac Pro1,1 and 2,1 are EFI32 so won't boot from the Velocity Solo x2, but will function as high performance storage.

I just did a bit of searching and it could be that the comment Iv'e seen on several product pages "The 2008 Mac Pro 3,1 is EFI64 but does not boot reliably, and therefore is not supported" might be in reference to the Solo X1, even though I've seen that on pages selling the X2. I guess some brave soul will have to give it a shot.

I have seen that too ... it is even on the Amazon description for the Solo X2 (unavailable). I even thought I had seen it on the Apricorn web site recently, but it sure indicates that the 2008 Mac Pro is compatible now. I think I may try one...
