Basically a SSHD is nothing more than a hard drive with a very deep cache (SSD). The drives hardware manages what should be held in this deep cache depending on how often it is called. So as an example your OS files and maybe some app files. If you constantly reload a given file it too maybe cached.

SSHD's are a good half step as larger SSD's are still quite expensive! A 1TB SSD drive is still over $400 U.S.

Some systems can't support two internal drives (i.e. HD & SSD) so a SSHD is a good option. If your system can support two SATA drives then getting a small sized SSD in conjunction with a standard HD could offer still better performance either as a fused drive (Apple Fusion Drive) or discreetly.

The other option here is a dual drive like Western Digital's Black2 drive. This is really two drives (HD & SSD) in one device. So far they only offer a 2.5" drive and is not very large and is a SATA III (6.0 Gb/s).

Here is the IFIXIT guide to replace your current HD: iMac Intel 27" EMC 2309 and 2374 Hard Drive Replacement.

Update (09/21/2015)

If you are thinking of giving up your optical drive for a second drive this is the IFIXIT guide to follow: Installing iMac Intel 27" EMC 2309 and 2374 Dual Hard Drive and here is the IFIXIT drive carrier: 2.7 mm SATA Optical Bay SATA Hard Drive Enclosure.

Then you could go with a straight SSD in it and a standard HD to replace your current HD. I don't recommend going with a SSHD if you plan on using a SSD with it as most people want to create a Fusion drive set (combining the SSD with the HD as one virtual drive letting the OS manage the file placement). If you do plan on keeping the drives independent then there is no issues.

Update (09/21/2015)

Here is the Apple P/N's for the thermal sensor cables if you go with a different HD or install a SSHD.

  • 922-9223 - Hitachi
  • 922-9224 - Seagate
  • 922-9225 - Western Digital

One last issue is Yosemite had issues with 3rd party SSD's. With the latest update that problem is now resolved!

This answer was originally to another question.

You've got a iMac that is very upgradeable. I had one of these and looking for speed and reliability i wanted a SSD AND a traditional Hard drive. With these iMacs you can open it up and install BOTH the SSD and your 3.5in HDD with replacing the CD/DVD drive in your imac and installing a hard drive caddy. They allow you to keep a big storage type device like your Seagate drive and use a SSD at the same time. Im sure there is a guide here on iFixit but you can get the jist of it looking on youtube. Just something ive found to be very cool considering Apple products. Look into it. Dedicated SSD's are far better than the SSHD's.

This is the caddy: http://www.amazon.com/SATA-Drive-Caddy-A...

Hey there and thanks for ur comment . My question is really if I can add a hybrid sshd Seagate that I mentioned before as the main hdd. I've been reading in many places that for this model iMac I should get the same brand as the one that comes as factory set.... Which is a WD. So I was expecting someone here that really knows about it. I was considering changing the optical drive to a ssd or another hdd with high capacity. But not untill I know for sure what to do with my first problem. Pls help

@Carlostimon - No, you don't need to replace your current drive with the same brand drive. If you do switch it out you'll need to also switch out the drives thermal sensor cable to match the drive you put in. Sadly, WD doesn't offer a SATA II (3.0 Gb/s) SSHD drive. Here's what the do offer: WD Desktop SSHD. The Seagate SSHD drives has auto sense and will work in your system. Here is the Seagate specs: Seagate Desktop SSHD. Review the SATA speeds they support.

Hey Dan thanks for ur reply! Which do u think personally I should take, I'm looking for SSHD hybrid of 2gb or more.?

Storage space is always a difficult question. What is just fine for one person is not enough for the next. You also need to look at your pocketbook and the age of the system here. Older systems days are numbered so putting to much into them may not pay in the long run.
