I recently purchased a maxed out iMac:
- NVIDIAGeForceGTX780M 4GB GDDR5
- 3.5GHz Quad-core Intel Core i7
- 8GB 1600MHz DDR3 SDRAM-2X4GB (upgrading to 32GB myself)
- 256GB Flash Storage
...and I'm questioning the last point above (I still have time to change my order). I know the iMac is limited to a single SATA III and a PCIe slot for storage, but I'm trying to balance performance with capacity with future expandability. I fear that my choice of the 256GB SSD is limiting me, since I won't be able to add a hard drive in the future. My questions are:
Which is faster, the 128GB PCIe SSD that comes in a
Fusion Drive
configuration, or the 256GB SSD I purchased?Is the PCIe connector compatible with the typical PCIe SSDs sold for PC use, or is it something proprietary like in the Retina MacBooks?
Is it worth sticking to the stock 1TB HDD and installing my own PCIe SSD to make a DIY Fusion Drive (I.e. Are there compatible PCIe SSDs for less than $180)?
