I want to upgrade the HDD in my aging laptop to a hybrid SSHD.
(Know any good 1TB or 2TB hybrid 2.5" drives, in the $100 neighborhood?
I'd like to hear recommendations.)
But that's not what this post is about.
See, while I was shopping around, I noticed some funny business from Seagate.
I was skeptical of their reliability because of the high failure rates reported by BackBlaze. So, I was really paying attention to the datasheets.
And I ran across a couple Seagate products with nonsense specs, involving "Multi-Tier Caching Technology (MTC)".
What, you ask, is "Multi-Tier Caching Technology (MTC)"?
Good question. Seagate helpfully describes it like this:
"Multi-Tier Caching Technology delivers snappy performance" ....
"By applying intelligent layers of NAND Flash, DRAM and media cache technologies, BarraCuda delivers improved read and write performance by optimizing data flow, allowing you to load apps and files faster than ever before."
And now you're supposed to be all like:
"Wow, 'media cache technologies'?! Those are my favorite kinds of cache technologies! Here, Seagate, shut up and take my money already!"
The quoted text is from the Overview of a 2TB 2.5" BarraCuda drive on NewEgg: ST2000LM015
It comes with a $99 price tag, and a 2 year manufacturer's warranty.
Similar text describes "MTC" on a 2TB 2.5" FireCuda drive, also on NewEgg: ST2000LX001
It comes with a $120 price tag, and a 5 year manufacturer's warranty.
First of all, is the reliability of the FireCuda drives really that much better than BarraCuda?
Or is the longer warranty just PR, to counteract the negative BackBlaze press?
And secondly, I have a challenge for anyone who actually stops to read this post:
Tell me exactly how much "NAND Flash" is in the "MTC" on these two drives.
I dare you.
It looks like Seagate is trying to see how close to deceptive marketing they can get without actually crossing the line.
What kind of crap is Seagate trying to pull here?
They're selling drives with undisclosed amounts of Flash on board. That number is literally what we're paying for when we buy hybrid drives, and they don't have the courtesy to tell us how much we're getting?
Well, Forum, over to you.
Thoughts? Opinions? Better, non-Seagate options?
PS: I did get actual numbers for quantities of flash on those two drives. But it took two rounds of email with Seagate to get a straight answer. I'll post their answer if anybody wants to see it.
