25GB? $50? Which one?25GB Samsung M2 SSD costs approx 50 USD , the 'recommended' PCI-E cards cost more than that
I am just looking to see if they are compatible ?
If you can get these SSD for $50, I will say that's a pretty good deal. But I really can't see why you need to go this route. The adaptor is expensive, and at the end, you won't get some extreme speed.Sorry I meant 256GB
Anyone of the following ?
No, those cheap adaptor is for PCIe SSD (AHCI or NVMe), NOT ( I say again, NOT) for m.2 SATA SSD.Because a regular SATA SSD in one of the drive bays would be limited to SATA 2 which would offer nearly half the transfer speeds
I am looking to go down this route because cheap M2 PCI Express adapter cards are only $5 and allow me to use SATA 3 speeds (approx 500/450 mb/s read&write)
NO. Those cheap card is NOT for your targeting SSD. They are cheap because there is no SATA controller onboard. You may able to get a relatively cheap PCIe SATA card, however, not necessary bootable. Also, they are relatively cheap because their speed is no way close to your 550MB/s targeting speed (may be around 350MB/s). If you don't want to bottleneck your SSD, you will need an expensive PCIe SATA card.No cheap M.2 PCI-E cards exist ?
It would be my OS drive with software installed. For a small outlay I don't see why I should bottleneck my system with Sata 2
Co-incidentally, I also use my Mac for photo editing and videos encoding.I appreciate what you are saying but you don't even know that I intend to photo edit and encode video.
There is no great expenditure for me over a SATA drive. Will a cheap M.2 PCIE adapter work or not?
