SSHDs Debut On the Desktop With Mixed Results

crookedvulture writes "Seagate's solid-state hybrid drives have finally made it to the desktop. The latest generation of SSHDs debuted with a 2.5" notebook model that was ultimately hampered by its slow 5,400-RPM spindle speed. The Desktop SSHD has the same 8GB flash payload and Adaptive Memory caching scheme. However, it's equipped with 2TB of much faster 7,200-RPM mechanical storage. The onboard flash produces boot and load times only a little bit slower than those of full-blown SSDs. It also delivers quicker response times than traditional hard drives. That said, the relatively small cache is overwhelmed by some benchmarks, and its mechanical sidekick isn't as fast as the best traditional hard drives. The price premium is a little high, too: an extra $30 for the 1TB model and $40 for the 2TB variant, which is nearly enough to buy a separate 32GB SSD. Seagate's software-independent caching system works with any operating system and hardware platform, so it definitely has some appeal. But dual-drive setups are probably the better solution for most desktop users."

They seem to have forgotten a little defect. SSDs have a low failure rate, high speeds, okay prices, but everyone's scared of flash memory degradation after a number of writes. Some crappy one would get 1500 write cycles on a chip but OCZ ones get 9000 which, even at my high usage on a 128GB drive, is at least 8 years before it fries.
So Seagate decides to take the biggest pitfall and hated feature and put it into a hybrid drive. All data written to the gigantic drive is passed through that 8GB buffer first. Flash memory that can put up with that amount of writes over the long term doesn't exist. These drives would maybe last a year or two if you're lucky.

The article says,

the SLC zones store boot data and cache some incoming writes.

One of you is wrong.

I've had SSHd running on all mu computers for 15y+

I really do hate overloading acronyms. SSH / SSHD is pretty well known already. It's what most unix folks (and I really do hope that that is the majority of slashdot readership) use to log on to servers every single day.

C'mon.
