Score: 80/100Rankings
The SanDisk Extreme Portable SSD 1TB delivers high-performance NVMe speeds of up to 1,050 MB/s read and 1,000 MB/s write while offering IP65 water and dust resistance in a lightweight 52 g package. Its capacity is limited to 1 TB and it lacks the ultra-fast 2,000 MB/s class of newer models. Ideal for creators and mobile professionals needing fast, rugged portable storage.
The WD_BLACK SN770 2TB is a DRAM-less PCIe Gen4 SSD delivering up to 5150 MB/s reads and 4850 MB/s writes with a robust 1200 TBW endurance. Its budget-friendly price and low power draw come at the cost of no onboard DRAM and no included heatsink, which can limit sustained performance under heavy loads. Ideal for gamers and mainstream builders seeking fast sequential performance without the premium price.
