24 comparisonsSamsung T9 wins for professional video production workflows where 2,000 MB/s matters. SanDisk Extreme wins for everyday portable storage — $40 cheaper, longer warranty, better drop protection. For most buyers, 1,050 MB/s is more than fast enough and the SanDisk's value proposition is compelling.
The SanDisk Extreme PRO Portable SSD V2 is the faster drive: Tom's Hardware measured it near its 2,000 MB/s USB 3.2 Gen 2x2 rating, about double the 1,050 MB/s PCMag recorded on the T7 Shield. Samsung’s answer is toughness — IP65 plus a 3-meter drop rating that Wirecutter’s portable-SSD coverage treats as the reason to pick the Shield over slimmer metal sticks — plus a body that hits full speed on any 10 Gbps USB-C port. SanDisk’s 5-year warranty versus Samsung’s 3-year is the other hard gap; pick Extreme PRO V2 if you have a 20 Gbps port and move large files daily, T7 Shield if the drive lives in a bag or on a set.
Crucial T705 2TB leads in raw speed with 14500 MB/s reads versus 7450 MB/s on the 990 EVO Plus per manufacturer data sheets.

For users who prioritize raw speed for 4K video editing, the Samsung is the better pick; for budget‑constrained gamers, the Crucial offers sufficient performance at a lower cost.
The Samsung 990 Pro dominates raw performance, delivering up to 7.45 GB/s sequential reads (Tom's Hardware) and a 1,200 TBW endurance rating, making it ideal for demanding desktops. The T7 Shield, however, wins on portability and durability with an IP65 rating and AES‑256 encryption, offering 1.05 GB/s over USB 3.2 Gen 2x2 (Tom's Guide). Choose the 990 Pro for stationary high‑speed workloads; pick the T7 Shield if you need rugged, on‑the‑go storage.
The LaCie Rugged SSD Pro delivers roughly double the sequential throughput of the Samsung T7 Shield (2000 MB/s vs 1050 MB/s per Tom's Hardware and CNET) and a more robust IP55 rating, making it the clear choice for demanding field work. However, its $399 price is significantly higher, so budget‑focused users may prefer the T7 Shield, which still offers respectable 1 GB/s speeds, IP65 protection, and AES‑256 encryption at $199. Overall, LaCie wins on performance and durability, while Samsung wins on value.
The LaCie Rugged SSD Pro is the better choice for creative professionals who need high-speed data transfer, with speeds of up to 2800MB/s (per Tom's Hardware).

For the average user who wants some peace of mind about drops and spills, the T7 Shield at half the price is the sensible choice. For professional videographers, photographers on location, and anyone who genuinely needs maximum speed and serious physical protection, the LaCie Rugged SSD Pro earns its premium.
The SanDisk Extreme Pro V2 has a slight edge thanks to IP65 dust and water resistance and marginally faster sustained write speeds. The Samsung T9 is the better pick if you want Samsung's excellent software ecosystem and slightly better build quality feel.
The WD My Passport is the safer buy. WD's reliability track record at this capacity is slightly better, and the included WD Backup software is more capable than Seagate's. The Seagate is often $10–$20 cheaper and works fine for simple drag-and-drop backup.
The Seagate IronWolf Pro has a slight edge — better sustained throughput, a 300 TB/year workload rating vs WD's 180 TB/year, and free IronWolf Health Management software. For Synology NAS users specifically, IronWolf drives carry additional validation through Synology's compatibility program.
These products serve fundamentally different purposes: the Synology DS923+ is a 4-bay NAS server (per Synology specs) while the WD Black SN850X is a single PCIe 4.0 SSD (per WD datasheet). The DS923+ excels at shared network storage with RAID but trails on raw speed; the SN850X wins on throughput and endurance for internal use. Direct comparison is not meaningful.
These products serve fundamentally different purposes: the DS923+ is a complete 4-bay NAS for shared network storage while the SN850X is a single high-speed internal SSD.
