Seagate Desktop SSHD 4TB Review - Big Hybrid, Little Cache

Subject: Storage
Manufacturer: Seagate
Tagged: sshd, Seagate, hybrid, 4TB



We've looked at many hybrid options over the past few years. First we checked out Intel's RST Caching solution, introduced on the Z68 chipset. Then we looked into Seagate's first few rounds of SSHD's, which were basically a standard HDD with an 8GB cache tacked on to the controller. Despite larger adoption of SSD's taking place, Seagate continues to push further into the hybrid market, with the addition of dual mode caching and other advancements. Today we take a look at their most recent push:

Yup, that's 4TB of hybrid goodness right there. No doubt this is a desktop class product, but how well can it handle desktop workloads?

Would be good to see the drive performance after the whole of the flash cache has died and to see how long the flash lasts.

Even though it is small, the cache will very likely outlast the mechanical portion of the drive.

Can i use Intel's SRT with a RAID array? One Samsung 840 pro for the OS and two WD RED in RAID 1 with a cheap 64GB SSD for caching for the array.

I haven't tested that specific config, but I believe you can use SRT caching on a RAIDed pair.

Just bought two 5TB drives for $189 each. Doesn't seem that the performance gain is worth the loss of capacity.

What 5TB drives did you get? and where did you purchase them? That price sounds really good, I'm looking to put in a couple bigger drives in my rig that I can run in Raid.

Just bought a third. 32TB and three bays left...

Amazon - STBV5000100. Get some guitar picks to open the external enclosure without scratching it, takes like 1-3 minutes, plug into computer, convert to GPT, format, done. I still don't know why the external hard drives are so much cheaper than the internal drives. Loss leader? Inferior components?

This seems like a cheap wholesome price for such components , i quer also where they came from , i,m trying to expand my storage to usage space internally...

I went from having a 150gb hard drive in my my main install position , after trouble with excorcising my routines i decided to install a 2tb sata in the same position , this catered for a lot of the process problems i seemed to be having with renders and games.I split the drive using windows to decompartmentalise my machine and joy of joys it worked , like having a finely tuned engine .I am now happy again although i would like to get some larger one drive spaces to advent my back ups.

It seems to me that these kinds of drives are best used as the drive for your OS and not used for games and files and such. I have one of the 750gb models and it used to be my only drive. When comparing bootup times between it and our other pc with a regular spindle drive, it was a good bitfaster.
But for games? Unless you play the same 2 or 3 games over and over again, the amount of flash memory on it just doesn't make a difference. I really think that with the prices of flash memory falling that seagate should have put more on these kinds of drives, at least doubled it to 16gb.

Is there any benefit in using this SSHD for a data drive, e.g. for storing home videos on a server rig for streaming over wired network?

Does the firmware erase(move out) data in the cache that is not used to much in order to make space available? Would this be useful in a dual boot scenario where one os is not used to often thereby freeing up cache space for the primary os?
