2TB SATA SSD for NAS caching
This 2TB SATA III solid-state drive is built for network-attached storage appliances that need a fast cache tier. The 2.5-inch form factor fits standard drive bays in modern NAS enclosures. Sequential reads reach 560 MBps and writes reach 520 MBps over the 6 Gb/s link.
Suits caching and mixed workloads, not cold archive
The drive targets OLTP databases, multi-user file shares, photo rendering and 4K or 8K video editing where low latency matters. Its 2500 TBW endurance rating supports continuous 24/7 operation. Users who only need bulk archival storage on a tight budget should consider hard-disk alternatives.
2TB capacity with 2500 TBW headroom
At 2TB the drive holds a large working set for caching hot data and accelerating frequent reads and writes. The 87000 read IOPS and 83000 write IOPS handle heavy random traffic. Once the 2500 TBW threshold is reached the warranty endurance limit is exhausted and the drive should be replaced.

Perguntas sobre este artigo
What does my NAS need to use this 2.5" SATA III 6 Gb/s SSD as a cache drive?
A free 2.5" drive bay with SATA data and power connectors, plus a NAS OS that supports read/write caching on a SATA SSD.
Will this Red SA500 2TB drive work alongside my existing mechanical NAS drives?
Yes, it connects over the same SATA III 6 Gb/s interface and is built for mixed SSD/HDD NAS volumes and caching tiers.
How can I verify the drive is delivering its rated 560 MBps read and 520 MBps write after installation?
Run a sequential benchmark such as CrystalDiskMark or the NAS built-in storage test and compare results to the 560/520 MBps spec.
