Silicon Motion SM2263XT HMB SSD Preview

[Guest]

Today we take an early look at a DRAM-less SSD that is faster than nearly all other SSDs shipping today. Yes, DRAM-less!

DRAM-less SSDs should have to advertise that in giant letters on their box so that consumers know to avoid them. Those mixed I/O numbers are pathetic.

Is it correct that a 1 TB SSD will have 1 GB of DRAM, or is that a typo, or did I read it wrong? Sounds like a pretty big lookup table.

The new gen HMB-capable DRAMless SSDs (with FCU or later) are good enough for most consumers. Also most PC users buy OEM boxes... I'd much rather see users offered a machine with HMB DRAMless SSDs than HDDs or non-HMB DRAMless SSDs.

Heck, for secondary storage (mechanical drive replacement, media storage) even QLC drives will be OK, so long as they're well-designed.

Newer hardware and operating systems allow PCIe devices to flag data headed directly to system memory. Even though the system memory and PCIe bus are on opposite sides of the CPU, the flagged data passes through the processor without adding parasitic load.

That answers the first question that came to mind. What are the requirements for direct-to-memory flag support? Is it only a question of PCIe version x.xx and OS + SSD support?

Whatever. I'll take a DRAMless SSD over a spinning hard-disk every time.
