SLC/QLC hybrids?

The MiDrive claims to use SLC for "hot" access, instead of a cache.

The QLC is assigned to storing less recently used files:

Perhaps AI technology could be applied to perfecting
such a hybrid combination.

"4x4" AICs offer lots of potential with PCIe 4.0

With the arrival of PCIe 4.0 chipsets, builders now have an opportunity to design very high-performance storage
using multiple "4x4" AICs, provided that the chipsets support bifurcation. Also, some of these "4x4" AICs
are described to work in multiple x16 Gen4 slots. The latter configuration should allow a RAID-0 array
to span multiple AICs, e.g. the ASRock Ultra Quad M.2 AIC. As such, picture two "4x4" AICs with a
total of 8 x Gen4 NVMe M.2 SSDs. The MiDrive (see above) should be objectively reviewed with
such an 8-drive config. p.s. Contrary to lots of sincere warnings we received before doing this,
we have standardized all of our workstations on a RAID-0 array for the Windows C: system partition:
64-to-100GB are formatted for C: and the remainder formatted as a dedicated data partition.
None of the "dooms" predicted by those warnings have ever occurred, over a period spanning
several years now. Looking back, I believe ONLY ONCE did we ever have to secure-erase some
older Intel 6G SSDs: even after secure-erasing all 4, the measured performance stayed the same!

And, with 20/20 hindsight, I now recall that we did a secure-erase of our older Intel SSDs
because we were trying to isolate a very serious, intermittent problem that was corrupting
our drive image files being written by an older, working version of Symantec GHOST.

I remember now the sequence: one experiment involved flashing the latest motherboard BIOS.
When we re-booted with the latest motherboard BIOS, a new default enabled the long DRAM test,
and during POST the counter STOPPED before reaching the DRAM total installed in that PC.

VOILA!

This proved that we had a failed DRAM stick, and the vendor mailed us a check for the
original retail amount (because that DDR2 was no longer being manufactured by that vendor).

We installed some new G.SKILL DDR2, and our problem was solved!

So, in the end, our older Intel SSDs really did NOT need to be secure-erased, after all.

I was frankly to blame for not considering a failed DRAM stick much earlier during trouble-shooting.

I've had 0 SSDs die. Even my first OCZ 128 was still alive when I tossed it.

I've had zero SSD drive failure while running in windows stripe/mobo raid, n I've been using it consistently at home for at least 5 years now. now @ 2x2tb660p & 4x1tb sammy 8x0 sata ssd, nvme is sys + installed, sata is everything else. I don't do anything valuable enough to warrant the need for proper redundancy. Keeping installers, docs, etc on the separate sata stripe at least provides some risk mitigation. I rarely have to re-install windows , which i believe is partly due to my using LTSC enterprise. I'll eventually grab one of those high speed wifi NAS units for proper backups now that I no longer have my X79 build

the inherent risk is still there, either way.... was my original point.

R.I.P. Zawarudo, may you OC angels' wings in heaven.

I might be wrong about this, but we have tried to purchase SSDs that are described as being capable of some internal error correction.

And, I believe the Samsung 840, 850 and 860 SSDs that we have assembled in RAID-0 arrays also do their own internal garbage collection.

As such, our setups do run the risk that the performance of these C: partitions on RAID-0 arrays of SSDs will slowly deteriorate, without doing periodic secure erasures and TRIMs.

Our Highpoint 2720SGL controllers do NOT support TRIM on RAID-0 arrays.

But, we haven't noticed any serious performance deteriorations with these RAID-0 arrays.
