Samsung starts mass producing super fast PCIe SSDs for ultrabooks

Samsung already makes one of the fastest and most reliable SATA-based solid-state drives for desktops and laptops. Now, the company is looking to bring even faster speeds while enabling thinner form factors with a new line of PCI Express (PCIe)...

The SSD revealed by iFixit looks nothing like the one shown here, and the performance is quite different. Maximum read speed in the new Macbook Air can reach 800MB/s, which is way slower than the 1400MB claimed by this component from Samsung.

This brings us to a conclusion that we are looking at two different products...

Possibly given them the slower model to say screw you Apple, or this could be a recently made model which is why they didn't have it. Either way it's nice to see something new helping the portable market, with it's terrible battery life situation. They tend to sacrifice a lot to add any sort of drive in, and also the speeds don't even compare to this.

I'm hoping it becomes more common in the general portable market, because then we might eventually see it trickle into possibly more useful situations. Just that's my general thoughts.

That's different. The PCIe device itself supports TRIM but Windows cannot issue TRIM to PCIe device.

Ok. I feel like I need to clear up some confusion. Some sites are reporting TRIM support and we're saying there is no TRIM support.

The RevoDrive 3 X2 has hardware support for TRIM through VCA 2.0. This much is true, but you can't use TRIM because of a software problem. As for why?

OCZ has a problem getting the TRIM command to the RevoDrive 3 X2, because it uses SCSI commands over PCIe, hence StorPort SCSI drivers. The TRIM command is out of the question because it's technically part of SATA. The only alternative is Unmap, which is to SCSI what TRIM is to SATA. Unfortunately, Windows does not support Unmap as part of its native driver stack. Furthermore, TRIM commands are only issued by Windows 7 when you empty the Recycle Bin, but you must have your SSD set to AHCI (part of SATA). Obviously this different from SCSI. So effectively no TRIM.

We have been in contact with the Windows driver team and OCZ, so we know that a fix is being explored. If it materializes, that's another matter....

(RevoDrive and RevoDrive X2 don't don't support TRIM at the hardware level, so the issue is moot for them.)

This is one example of why I'm asking - wonder if Samsung may be different to the OCZ Revodrive scenario.

Or Apple throttled it.
