Spec Comparison
TL;DR: The WD Green SN350 1TB delivers 3,200 MB/s reads, low‑power operation and a three‑year warranty at a budget‑friendly price, making it a solid entry‑level NVMe upgrade.
This drive’s standout spec is its 3,200 MB/s sequential read speed and 2,800 MB/s sequential write speed, powered by an 8 Gb/s PCIe Gen3 x4 interface. Random performance reaches 300,000 IOPS reads and 400,000 IOPS writes at 4 KB. The drive uses 3D QLC NAND and Western Digital’s Intelligent SLC Caching to keep latency low while keeping costs down.
Physically, the SN350 comes in a trim package: at 2.38 mm tall, 80 mm long and 22 mm wide, it is considerably slimmer and shorter than the WD Green 1TB, which measures 7.1 mm in height and 100.6 mm in length. It also weighs just 7.5 g, far lighter than the 32.7 g of that sibling model. Compared with the SN730 256 GB, the SN350 shares a similar height (2.54 mm vs 2.38 mm) but offers four times the capacity. It is also lighter than the WD Blue SN5000 500 GB, which tips the scales at 5.7 g, and it fits the same M.2 2280 single‑sided form factor as all the other drives in this roundup.
Everyday users rave about the noticeable boost in boot times and application launches, praising the “fast boot and app loading” they experience after swapping an old HDD for this SSD. Professional reviewers note the clear performance jump over SATA SSDs and highlight the inclusion of the WD SSD Dashboard for health monitoring. Some users report that write speeds feel capped at the 2,800 MB/s ceiling during large file transfers, and the QLC NAND’s 100 TBW endurance is lower than TLC‑based alternatives, which can be a concern for heavy write workloads.
Beyond speed, the drive draws only 110 mW in active use and tops out at 5 W, helping laptops stay cool. It includes low‑density parity check (LDPC) error correction and comes with a three‑year limited warranty, offering peace of mind for budget‑focused builds.
Pros
Cons
Best for: Budget-conscious buyers seeking a reliable entry-level option
Avoid if: You want the best value‑per‑dollar in its price range
“dramatically improved system performance, with boot times dropping from over 2 minutes to under 30 seconds”
“drive disconnection issues, requiring reseating”
TL;DR: The WD Blue SN5000 500 GB delivers up to 5,000 MB/s read speed in a tiny, single‑sided PCIe 4.0 package, making it a solid mid‑range upgrade for everyday PCs.
The standout spec is its sequential read speed of 5,000 MB/s, which sits at the top of the budget Gen4 tier. Paired with a 4,000 MB/s write rate and a DRAM‑less 4‑channel controller, the drive offers fast boot‑up and app load times while keeping power draw low at 6.3 W peak.
Compared with the other six WD SSDs in this roundup, the SN5000 reads faster than the WD Green SN350’s 3,200 MB/s and the SN730’s 3,150 MB/s, and its random write performance of 770,000 IOPS eclipses the SN730’s 280,000 IOPS. Capacity-wise it sits at 500 GB, smaller than the 1‑TB and 2‑TB models but larger than the SN730’s 256 GB. At 5.7 g (0.012566348934 lb) it’s lighter than most peers, though the WD Red 1TB is marginally lighter.
Users consistently praise the drive for snappy system starts and the peace of mind from a five‑year warranty. Professional reviewers note the jump in performance over the older SN580 and commend the use of 112‑layer TLC BiCS 5 NAND for better endurance. Some buyers have reported occasional heat buildup near the 60 °C idle limit and have run into fulfillment mix‑ups or slow seller support, so keep those considerations in mind if you’re sensitive to temperature or service response.
Additional technical highlights include a thin graphene heatspreader that removes the need for an external heatsink, single‑sided M.2 2280 form factor for slim laptops, TCG Pyrite 2.01 encryption, and bundled Acronis True Image software. The drive’s endurance rating of 0.33 DWPD and 300 TBW provides a reliable lifespan for typical desktop workloads.
Pros
Cons
Best for: Home and office users seeking a balance of features and value

“drive disconnection issues, requiring reseating”
TL;DR: The WD Green 1TB SSD offers a budget‑friendly 1 TB capacity, SATA III speeds up to 545 MB/s, and ultra‑low power draw, making it a solid upgrade for everyday laptops and desktops.
This drive packs a full 1 TB (1000 GB) of 3D TLC NAND in a 2.5‑inch / 7 mm form factor, delivering sequential reads up to 545 MB/s and writes up to 525 MB/s. Its active power consumption is only 80 mW, and it weighs just 0.072 pounds (32.7 g), which helps keep laptops cool and extends battery life.
Compared with the WD Green SN350 1TB, the Green is heavier (32.7 g vs 7.5 g) and slower in sequential reads (545 MB/s vs 3200 MB/s), but it still undercuts many larger SATA drives in price. The WD Blue 1TB weighs a similar 0.076 pounds, so the Green isn’t noticeably bulkier, and both share the same 7 mm height.
Reviewers praise the ultra‑low power draw and the bundled WD SSD Dashboard plus Acronis True Image for painless cloning. However, the absence of a DRAM cache and the limited SLC caching lead to slower random performance once the cache fills, a point that everyday users often mention in their feedback.
Technical highlights include a mean time to failure of 1,000,000 hours, 400 TBW endurance, and a shock resistance rating of 1,500 G. The drive operates safely between –55 °C and 70 °C, and its error‑correction uses LDPC to maintain data integrity.

“dramatically improved system performance, with boot times dropping from over 2 minutes to under 30 seconds”
“drive disconnection issues, requiring reseating”
TL;DR: The Western Digital SN730 256 GB delivers 3,150 MB/s sequential reads and 280,000 IOPS random performance at a $55 price, but its 256 GB size and lack of DRAM limit heavy workloads.
The SN730’s headline spec is its 3,150 MB/s sequential read speed, backed by 280,000 IOPS random reads and 280,000 IOPS random writes. At just 9 g and a slim 2.54 mm profile, it fits easily into ultrabooks and compact desktops. Power use is modest, with only 30 mW idle and 3.5 mW in extreme sleep, making it friendly to battery‑run machines.
Compared with the other six Western Digital drives in this roundup, the SN730 is far faster than the SATA‑based WD Green 1TB (545 MB/s read) and WD Blue 1TB (560 MB/s read). Its read speed is on par with the high‑end WD Green SN350 1TB (3,200 MB/s) but its write speed of 2,100 MB/s trails the SN350’s 2,800 MB/s. In size, it matches the WD Blue SN5000 500 GB at 2.54 mm height, yet it is a bit heavier than the SN350’s 7.5 g. The drive’s endurance of 200 TBW and MTBF of 1.75 million hours sits between the lower‑end Green models (400 TBW, 1 million‑hour MTBF) and the higher‑end Red 1TB (600 TBW, 2 million‑hour MTBF).
Users praise the SN730 for lightning‑quick boot times and the peace of mind a five‑year limited warranty gives. Everyday reviewers note the drive feels reliable in laptops and small‑form‑factor PCs. The most common complaints focus on the modest 256 GB capacity, which can fill up fast for modern game libraries, and occasional slower write speeds during large file transfers—issues tied to the drive’s DRAM‑less design.
