Limited 5-years or 300TBW. 2. Limited warranty based on 5 years or 300TBW, whichever comes first. (*TBW is evaluated by JEDEC workload standard. ) *TBW (Terabyte Written): Terabytes Written is the total amount of data that can be written into a SSD before it is likely to fail. 3. When the usage of an NVME SSD as indicated by the 'Percentage Used' (SMART ID: 05) in SMART page of 'GIGABYTE SSD toolbox' reaches 100 means out of warranty. (A new unused product will show the number of 0) Note • Test system configuration: configuration may vary by models, we will choose the latest platform for verification. • Performance may vary based on SSD's firmware version and system hardware & configuration. Sequential performance measurements based on CrystalDiskMark and IOmeter 1.1.0. • Speeds based on internal testing. Actual performance may vary. • 1GB = 1 billion bytes. Actual useable capacity may vary.
