2) Forgive me if I'm wrong, but you can't use a PCIe drive as a boot drive...
Think of it as a raid controller with 2 drives attached.
If it has a boot ROM then yes you should be able to boot from it. I would imagine it would have a boot ROM as all the other PCI-E SSDs we've tested had one.
correct TRIM is not supported in raid. So it either has to have hard war trim or you are left dry. At overclockrs.co.uk thy say something about "garbage collection" but what that mean I do not know for sure.
Garbage collection is the old solution to performance degradation, before TRIM was finalised. IIRC, it is essentially a manual TRIM command, as it takes data from blocks that are not full and copies them to full blocks. This way, as many blocks as possible are filled, meaning new data being written doesn't have to go through the performance destroying read-copy-write cycle that plagues used SSDs.
For more info, see this.
And it can in fact be booted from. Don't ask me how they do it, but it has been confirmed.
It uses a fairly ancient SiIicon Image RAID controller (the 3124) which is bootable.
Box suggests it has trim.
More interesting, is that thing in the middle, it kinda reminds me of the ribbon connector on the dual GPU cards that join 2 PCBs together. Maybe some kind of 2 card raid thing ?
I'm saving for a PCIe SSD, been saving for a while and still nowhere near the cost of the one I want.
finally a good use for that little socket.
Those are grate pics.
Now I'm thinking of getting 1 for boot drive.....
Pretty curious, if this turns out to be as fast as claimed, I might get one of these :3 (Which will result in an empty wallet-)
Perhaps I'm getting the wrong general idea about this, but isn't it essentially the same idea as a FusionIO card? http://www.fusionio.com/products/iodrive/
It seems to be priced a little bit cheaper to penetrate the hardcore consumer market, but it looks like the same, which I hope is the case. Any competition for FusionIO would be great as it means prices will be driven down faster.
^ last I heard the fusionIO was not bootable unless they have fixed that......OCZ's drive is bootable....so big advantage
You can boot from PCI RAID cards though. Surely the BIOS would just see this as one of those?
A common BIOS boot option is 'Bootable Add-in Cards' after all.
Nice! but why does it have to cost so much? They got to get the prices down. Or at least have them come with Windows 7 64 bit already installed on them.
Hmmm. I guess that answers the letter I emailed in.
I expect we'll see more PCIe SSD's in the future as drives get too fast for SATA.
God Damn it!
I want it so much and I already have 2 OCZ Vertex's in RAID 0 ;D
this is SWEET, i'd love to get one
"a good job of keeping the price down with the 120GB RevoDrive costing £335"
when was the last time you ventured outside your room full of free test hardware and looked at the price of a loaf of bread?
£335 for 120GB? For £335 you could have 6TB of traditional storage... FIFTY times more space, and if you RAIDed them you could probably get close to SSD performance.
