** TOOK THE PLEXTOR 256GB M2 PCI-E SSD FOR A SPIN!! **

Are there any issues with using these PCI SSDs as bootable/system/OS install drives?

Hopefully there shouldn't be but I'm no expert, can someone chip in? Would like to use the M2 slot on my MSI Gaming 5 mobo for something like the Plextor (in PCI-E mode) for a fast Windows boot drive... Isn't that what the M2 slot is designed for? Suppose could use it for large caching of big spinny hard drives but not sure that would be the best use of resources.

BTW I think the M2 socket SATA III/PCI-E dichotomy is a bit confusing for unsuspecting consumers.... :(

oh your not wrong there, they have made a complete balls-up of it. PERIOD!


As for bootable, they should be, with the possible exception of the Samsung XP941 which apparently is a tad different and isnt supported by all yet.

Also, the adaptors to fit the regular PCIe sockets....... these are what needs to be bootable, some are and some aren't so do your homework first.

I will probably be getting one of these (plextors) to go directly into an Asus Maximus VII Gene board, because i don't trust the samsung to work right in it.
 
Here are the figures when we tested it on that MSI Gaming 5 motherboard as a PCI-E adaptor card and then as a M.2 drive.

Here it is as the OS on the PCI-E card.

Here it is as the OS on the M.2 Slot.

As you can see the scores are pretty similar.

You do actually get a bit of a speed boost if you do not use it as the OS drive. but it is only a small amount.

Yes they could have made it easier on everyone and only had them run at PCI-E rather than some at SATA III which then causes issues as to which board has what slot. I am trying to get a lost of what board does what. but if in doubt ask us and we will find out for you.
 
Interesting stuff but for the same price or less you can buy a couple of 250gb Samsungs and RAID them. Faster performance and twice the storage.

As most pointed out in the other thread the green PCB makes this look like a bit 90's.

These would probably benefit older systems more than new ones. Would be interesting to see how this performs on a 775 mobo.

Thanks, great test! Surprised the 'naked' board was slightly slower. Would prefer it tho just for using the M2 slot - a bit tidier ;)

Also, as was pointed out, one has to pay twice as much vs a 'normal' drive for not a great deal of performance increase, bit difficult to justify unless a real speed freak (is SATA III vs PCI-E even noticeable in real-world usage?)....
