Hello,
I already have a SSD Samsung 860 EVO 256GB and old HDD Hitachi 500GB. I want to replace the HDD. I'm thinking of buying a SSHD Seagate Firecude 2 TB but I read many not good reviews about SSHD. So I'm thinking of buying a HDD Seagate Barracuda 2TB + SSD WD Blue 500GB.
Currently the SSD use Ubuntu and I want to try and install some virtualizations (virtualbox) on the new disk like Windows and Mac OSX. I have 48GB DDR4 RAM So I think it'd be no problem for the virtualization. For this, Is it better and enough to use just single SSHD or use SSD + HDD? it'd be price vs performance compromise. also not sure the virtualizations would be used very often. But I really need big storage to store and backup my data.
Any answer would be appreciated.
 
Solution
There really is no significant advantage to SSHDs, it seemed like a good idea but really never worked out to be that useful. Go with an SSD and HDD.

edit: and be careful buying HDDs right now -- make sure that you do not get an SMR drive, many manufacturers are sneaking them into their line up and not making it apparent.

The only value of a HDD is the lower cost per gb of storage.
It seems to me that you might as well go all ssd.
If your motherboard has a m.2 pcie slot, a 1tb intel 660P is $120.
Or, a 1tb samsung 860 QVO is about the same.
2tb drives cost about 2x as expected.

For backup, a HDD is excellent. But a good backup needs to be EXTERNAL.
A usb connected HDD for backup would be good.

Thanks for the warning. anything to know how to find out the SMR drive? is it from part number or serial number?. I have a plan to buy HDD Seagate Barracuda 2TB from the official store. it says 2 year warranty for it.

Thanks. Yeah. I read the SSHD Seagate Firecuda 2TB specs. it seems like a combination of HDD 2TB and SSD 8 GB. With similar price I can get HDD 2TB + SSD 250 GB. Even a combination HDD 2TB + SSD 500 GB only a bit more expensive than the SSHD. With a limited budget, I'll go to the HDD and SSD combination.
 
If you need big storage, then get big HDD. 2TB is not that much.
I think 2 TB is more than enough for me. I need it as a backup and to store my old files that sometime I need to open them. Actually I have an external hdd as well. but the internal disk is more comfortable without have to plug/unplug it 😀
 
Yes, some 2TB are SMR -- reaad THIS article.
Thanks for the link. I did a bit research about SMR. it says not good for hard disk reliability. I found WD blue 2TB WD20EZAZ is a SMR drive as well (https://forums.overclockers.com.au/...mr-in-some-wd-toshiba-seagate-drives.1281846/) but WD20EZRZ is not. It seems the EZAZ model is 4 years newer than the EZRZ and has better specs. Do you think I should choose the EZRZ model for personal use (store files, photos, movies, backup, etc)? is it reliability-wise better?
I asked a WD official store in my country and only EZAZ model is still available.

I would buy an older PMR drive over a comparable SMR -- the writes after the first one to a sector will be quite slow with SMR, and reliability for other than archive use is an open question.
