As an anniversary gift I received a nMP with 256 SSD which is way too small for my needs.

I read that OWC is coming out with SSD upgrades for the nMP later this year. Is there an SSD upgrade for the nMP that's available now? Can it use an SSD designed for the MacBook Pro Retina?


Why not get the LaCie TB2 1TB external SSD?
It's supposedly faster and would make an excellent boot drive.
It runs 2 500GB SSDs in RAID0.
 
...
Why would it not be the same speed. The only way to obtain those drives would be from an actual late 2013 mac and therefore they would have the 750 read, 650 write speeds.

I think you missed the MBP in what I outlined. People have been selling the much easier to get their hands on MBP blades as MP blades upgrades. It is doubtful that many real MP 2013 blades are floating free. Apple isn't selling them. There are no 3rd parties to upgrade to and sell the old. Apple service vendors selling of rogue spare parts... not sure how that wouldn't set off alarms at Apple for when almost every deployed Mac Pro is practically brand new.


A x2 lane PCIe v2 SSD isn't going to match a x4 lane SSD v2 even if the socket, flash controller and flash are identical. Likewise there can be firmware and cache differences even if plug into the same socket.


The marketing page for Mac Pro ( http://www.apple.com/mac-pro/ ) has a "Storage section". Max SSD transfer time 1200MB/s . A different value than 750 and 650 MB/s. The MBP doesn't really have x4 PCie v2 lanes of bandwidth to completely dedicate to a SSD so there is little reason to put a 1200MB/s SSD in one. The Mac Pro 2013 has substantially more PCIe bandwidth so it does make sense there.
 
Just to clarify:

late retina Macbook Pro uses 2-lane PCIe SSD
late 2013 new Mac Pro uses 4-lane PCIe SSD

The 4-lane PCIe SSD has twice the bandwidth available for I/O
 
1 tb ssd

I have a 1 TB SSD in my nMP which gives me plenty of headroom. My medical imaging and video production software tend to take up a lot of space. I have several Parallels VMs on it which work extremely fast. Over 400 GB on the internal SSD already. All my media, backup and personal files are on a Pegasus2 TB2 enclosure. I have experienced significant slowdowns on my old MP with other SSDs (OWC and Samsung) once you fill the drive more than 50-60% capacity. A big SSD was a good investment for me.

Oops... I meant to say a 1Tb SSD as they use x4 PCIe and get nearer to 1000 read/write.
