Frequently Asked Questions

What is SAS 24Gb/s and how does it differ from SAS 12Gb/s?

SAS 24Gb/s doubles the per-lane bandwidth of SAS 12Gb/s — providing up to 4,200 MB/s sequential read on the PM1655 vs approximately 1,000 MB/s on typical SAS 12Gb/s SSDs. Requires SAS 24Gb/s HBA or RAID controller.

Is the PM1655 backward compatible with SAS 12Gb/s?

Yes — the PM1655 operates in SAS 12Gb/s controllers at reduced speed. Full SAS 24Gb/s performance requires a SAS 24Gb/s HBA or RAID controller.

What DWPD endurance does the PM1655 Mixed Use offer?

The Samsung PM1655 Mixed Use is rated at approximately 3 DWPD (Drive Writes Per Day) — suitable for balanced read/write workloads in database, virtualization, and analytics environments.
