Western Digital 4TB WD Blue SN5000 NVMe Internal Solid State Drive SSD - PCIe Gen 4.0, M.2 2280, Up to 5,500 MB/s - WDS400T4B0E

I wanted a reliable, fast ssd for a thunderbolt 4/usb4 enclosure. After much research, I decided on this ssd. Yes, it's not the fastest ssd, and not the latest PCIe5. However, it delivers write/read speeds in excess of the bandwidth limitations. I'm getting write speeds of over 2775MB/s and read of over 2850MB/s. And, with the abundant hybrid cache, the sustained writes don't seem to recede. Super fast, with less temperature/power issues (than the top of the line, newer ssd cards). It delivers the same throughput as the newer, faster cards (which would max out at about the same level, due to the bandwidth limits). Saved some money, which is always a welcomed feature. In the near future, I'll spend the savings on a faster card (probably the WD SN850X) when I purchase a thunderbolt 5 enclosure.Very pleased with the specs and real world performance of this ssd. Five stars, definitely.

Honestly, it's a Western Digital product and I've never had any issues with these M.2 drives. Sturdy and well made and are very fast. Mine have been installed in heat sink environments and do not present any heat issues. Good value overall given the superb performance. Easy install.

Fast SSD storage. Performs better than the original internal drive. I am using it on an external enclosure with faster data read/write speeds.

Western Digital Blue SN580 NVMe SSD 1TB ReviewI have a 10-year-old computer running Windows 10. The system drive has been upgraded from a mechanical hard drive to a Crucial MX500 SATA SSD. This really increased the boot-up speed and functioning of the computer.For the computer I was installing the SN580 NVMe SSD into, I had to purchase a M.2 NVMe PCI-E adapter because my 10-year-old computer does not have a M.2 slot. It does have an available PCI Express x16 (Gen 2.0) slot. The adapter I bought is backward compatible to Gen2.0.The NVMe SSD can only be used as a secondary drive in the computer I was installing it in because the computer’s BIOS will not boot from PCI-E. If the computer’s BIOS could boot from PCI-E I would have cloned the SATA SSD and made the NVMe SSD the system drive.INSTALLATION1) After connecting the NVMe to your computer (remember, typically, the card is inserted into the slot at an angle and then gently pressed down and secured with a screw).2) Power on the computer and go to Disk Management (Click the Microsoft logo in the lower left of the screen and type “Disk Management”.)3) A dialog box will ask you to initialize the drive. Do so.4) Locate the new SSD in the disk drive section. In the Unallocated section, right click and format the drive. After it’s complete, close Disk Management window and you’re new SSD should be ready to use.RESULTSIn my situation, I connected the WD SN580 to the computer’s PCI-E X16 slot using an adapter. I was blown away at the read/write speeds compared to the Crucial MX500 SATA SSD (being used as the System drive).The NVMe SSD, using PCI-E adapter, had tremendous speed. For comparison, here are the CrystalDiskMark results for the two drives installed in the computer:Read WriteCrucial MX500 SATA SSD: 285.1. 267.6WD Blue SN580 NVMe: 3,533.3 3,395.5Although not exactly a fair comparison because the two drives use different technologies, upgrading to an NVMe SSD in my situation was the right choice.FINAL THOUGHTSInstallation was straightforward. The Western Digital SN580 NVMe 1TB SSD performed extremely well and has a very good price point. Also, Western Digital, at the company’s website, provides Acronis cloning software free of charge and no registration is required. I recommend this product.

Works exactly as promised. Fast data transfer. Easy to format and install. I used this to create a backup drive and a file transfer drive on my new Mac Mini using a matching hub that I purchased separately. I was easily able to format and partition it. No problems. It does get a bit warm when hard at work, but it didn’t overheat even when transferring about 500GB of data.

I recently purchased the Western Digital 1TB WD Blue SN5000 NVMe Internal Solid State Drive SSD (WDS100T4B0E) and overall, I'm quite satisfied with its performance. The SSD delivers impressive read and write speeds, and it has significantly improved the performance of my laptop.That being said, the product didn't come as pictured. It is supposed to have a blue sleeve on it. I researched this and learned that it just depends on the batch the product comes out of. It isn't a common issue. The missing sleeve isn't necessarily a defect in the product. The sleeve has two purposes, one is for aesthetics (looks) and one is for heat dissipation. The reduction of heat dissipation due to the missing sleeve isn't very noticeable as my left palm rests on top of where the SSD is installed. I sometimes notice a little warmth, but the system fan kicks on and takes care of that immediately.The purpose of this review is to inform both Amazon and the consumer. I'm trying to help both entities in trying to mitigate returns due to the product not being shipped as pictured. I hope to reduce or eliminate unnecessary returns on the product to save both Amazon and the consumer the headache of returning it.That being said, I detracted the one star because the product not coming as pictured and not due to a defect or the product not working.

Strong performance and speed. I was impresed with the heat transfer and reliability. Great design from WD.

They work and are very fast compared to older technology hard drives. They do not get hot in a HP Prodesk 400 mini PC.
