Traditionally, PC storage is split between the fast and expensive SSD and the super slow but very affordable HDD complete with magnetic tape and needle. The latter is fairly ancient technology nowadays when it comes to PCs and with SSDs continually getting cheaper it’s easier than ever to ignore the big old magnetic drives.
But, there are still places for such technology. Mostly when it comes to mass storage because they offer much better value per GB. But there’s also a third way: The SSHD, also known as a hybrid drive. This combines a small amount of NAND flash storage, such as you’d find in a regular SSD, with the regular HDD style magnetic tape.
The idea is fairly simple: combine the speed benefits of SSDs with the mass volume of HDDs. The controller in the drive will decide what lives where, caching your most used data on the NAND, but ultimately a hybrid will be faster than a standard HDD.
So I grabbed a Seagate Firecuda 1TB SSHD to see what it’s all about.
Seagate Firecuda SSHD hardware and performance
Firstly, some quick specs.
|Capacity||500GB, 1TB, 2TB|
|Sequential read||Up to 140MB/s|
|Sequential write||Up to 140MB/s|
|Avg power consumption||1.8W|
|Durability||600,000 load/reload cycles|
It’s also important to note that Seagate employs Multi-tier Caching Technology (MTC) to utilize NAND flash, DRAM and media caching technologies to further squeeze the most from the drive.
One of the target audiences the Firecuda is pushed at is gamers, folks who want faster loading times than their huge HDDs but without sacrificing capacity. Gamers are also the type of user that will transfer large files once then leave them there, which is an ideal condition for best performance from an SSHD.
General file transfers to the mass storage on the drive still chug along the same as they would on a regular HDD. But in benchmarks, it’s a little clearer to see some of that performance gain.
