SanDisk NAS 600 SATA SSD 4TB · 2.5-inch 7mm NAS Internal Solid State Drive · 24/7 Rated · 2,500 TBW · Up to 560MB/s

The SanDisk NAS 600 SATA SSD 4TB (SDSNS2400TAB-000G0) is a 2.5-inch, 7mm SATA III solid state drive designed for continuous operation in 24/7 NAS systems, with up to 560MB/s read, 520MB/s write and an endurance rating of 2,500 TB written — aimed at small offices and creators who want a quieter, faster, all-flash or SSD-cached NAS.

Unlike a desktop SSD, it is specified for multi-drive and RAID configurations and for the shock and vibration of a chassis full of drives running around the clock.

• 1 × SanDisk NAS 600 SATA SSD 4TB, 2.5-inch 7mm
• No mounting screws, 3.5-inch adapter bracket or cables are listed in the box by SanDisk

• 2,500 TBW means the drive is rated to absorb roughly 2,500 terabytes of writes over its warranty — plenty for file sharing, backups and SSD caching in a small-office NAS.
• In a 1GbE or 2.5GbE NAS the network, not the SSD, is usually the bottleneck; the gain you feel is in random access — many users opening files at once, VMs, photo catalogues.
• An SSD array is silent and cool compared with spinning NAS drives, which matters when the NAS sits in an office.
• Use drives of the same model and capacity in one RAID group for predictable performance.

• It will not speed up transfers beyond what your network link allows — on 1GbE expect about 110MB/s regardless of the drive.
• M.2-only NAS slots cannot take it; this is a 2.5-inch SATA drive.
• It is not a replacement for a backup: RAID protects against a drive failure, not against deletion or ransomware.
