Seagate FireCuda SSHD vs Standard SSHD

"@mayer - Not sure it's something I would go with.

It's limited to SATA 6.0 Gb/s systems. Unlike the older SSHD drives which auto set to the systems SATA port. So it's a bit limited on which systems it will play in.The NAND is small than the drive I've been putting in the MacBook Pro's (Seagate ST1000LX001) which has 32GB unlike the FireCUDA which only has 8 GB.

It does appear to have a denser platters and run faster which gives it a bit faster read/write times. It's the same as the older SSHD with 8 GB of Flash but twice as dense (1 TB Vs 2 TB). Looking at the power the idle load is less and of course the case is now 7 mm Vs 9.5 mm which would allow it to be a good choice for the older Mac Mini's (SATA III models).

So far we are still able to get the older drive but I'm sure it will be phased out (our needs have also diminished for HD's in system upgrades). In the meantime we've been moving forward with upgrading to SSD's so that just might push us a little sooner."

"The CUDAFIRE should work just fine as your macOS hard drive in a non-fusion drive Mac . The interface is basically a SATA 3. As with most new drives out there, the drive is capable of much higher transfer speeds than the Mac interface can't handle so it dumbs down. The increase speed rates of transfer are basically due to a migration of Seagate technology's.

I found a article that might be of interest: Seagate launches FireCuda SSHD: Up to 2 TB SMR, 8 gb of NAND"

I can't tell you about speed, but I know one thing for certain: According to the SATA III standard, SATA III is in all cases backward compatible with SATA I and II unless the device does not support the SATA III standard. I never have worried about SATA revision compatibility.

"If the drive has real Sata it is always backward compatible.

Have tried out different drives in different laptops or on motherboards. But of course a Sata III drive connected to a Sata I controller is really not worth it tried it out on a laptop."

"@mayer, no I have not tried that drive, but check out this sandisk: https://www.amazon.com/gp/aw/d/B01F9G43W...

MLC and turbo cache (or whatever they want to call it) for $77+free shipping​ is a great deal.

Those OCZs are also a good deal though."

"I built a Fusion drive to my mini2012 with sandiskX400 128GB & 2TB Firecuda.

I didn't know there might be problems with sshd in Fusion drive.

Has anybody digged any deeper, why there are these problems?

Any links to any discussions about sshd & fusion?

Now the system (10.12.6) went black because of Security update. I've also had some beach balls before and other hickupps, but I've thought that's because I have lots of pixels (30""+23"") connected to mini.

Now I'm thinking if there might be something wrong with Fusion drive (128GB+2TB). Could it be fooled by my sshd, acting so fast with its ssd-like cache? Is there any logs or data somewhere in the system how well it works?"
