newegg sent the wrong item, but was quickly corrected. Correct item was shipped even before they recieved the returned item. Using the drive in a usb enclosure for system backup. Works fast

The WD BLACK SN850X 4TB w Heatsink drive is excellent as a fast (6960 MB/s R, 6560 MB/s Wr, in my system) PC boot drive as well as for an additional DDR4 storage drive. My PC boot time is now ~15 seconds faster than the original slug SSD. Snappy general use too.

The specs that are listed are spot on!

All the flowers you can give it

-Easy setup (partitioning and clean) -5 Year Warranty -No RGB -No heatsink -Fast and meets expectations -Micron made

speed test read speeds up to 14k MB/sec, and stable

Fast shipping. Working just fine.

-Super Fast, just as fast as advertised -backs up the WD reputation

- Preinstalled heatsink - Transfer rates up to 7,100 Mb/s, 4.0 x4 - Price per Gb - Crucial name and warranty (5yrs) - Free cloning and optimization software for download from Crucial website - Heatsink low enough to fit under adjacent video card


Got 14k reads like it was promised in a bench test

The drive installed easily and seems to be working properly.

-Fast boot time -Fast data transfer speeds

I replaced my sshd. With this one in my 2018 Asus FX504, and what a difference!!!! Very happy so far!!!

Super easy to physically install. Drives like this on fit in 1 possible way; they're notched for dummies. Massive performance increase over usb external hard disk drive.

-Quick and boot up games faster than normally. Product itself works like a charm -Got here faster than expected.

- speed - reliability - ease of setup - doesn't require Samsung Magician to run. The software does have great features though

Have two of SP UD 90 m.2s, got 1T from another online store months ago and its surprised how well it was running. So, got another one , 2T from newegg recently as storage. Both run around 4900/4500, per CrystalDiskMark, and able to transfer large 50-70 Gig folders without much up/ downs.

Really good quality/speed for the price. Good temp. No driver issue.

Works good it's in my current setup
