Western Digital WD10EZEX 1 TB PC Hard Drive - Blue, Mechanical Hard Disk

Product Information

WD seems to have gotten around this hurdle with the addition of a much smaller SRAM chip ("static" RAM to DRAM's "dynamic" RAM). SRAM chips are faster than DRAM, though they can be more expensive to implement. WD also found a workaround for this, including just a few megabytes of SRAM on the in-house Western Digital controller, rather than the larger SRAM caches that you might see on other drives that implement a similar technique. Based on read speed, unless otherwise specified. As used for transfer rate, megabyte per second (MB/s) = one million bytes per second. Performance will vary depending on your hardware and software components and configurations. Last up is a series of file and folder transfers done in the SSD benchmarking utility AS-SSD. This trio of tests involves copying large files or folders from one location on the test drive to another…

Western Digital Blue 1 TB SATA 2.5-Inch Hard Drive

TBW (terabytes written) values calculated using JEDEC client workload (JESD219) and vary by product capacity. A WD Blue SATA Internal SSD can last up to 1.75M hours MTTF 2 (mean time to failure), with up to 600 TBW 3 (terabytes written), and has built in technology to correct errors in real time. As used for storage capacity, 1GB=1,000,000,000 bytes and 1TB=1,000,000,000,000 bytes. Actual user capacity may be less depending on operating environment As used for storage capacity, 1GB = 1 billion bytes and 1TB = one trillion bytes. Actual user capacity may be less, depending on operating environment.

Thank you!

One of the main upgrades from the older SN500 model that we tested last year is the increase in PCI Express lane allocation, which directly affects peak throughput. The WD Blue has gone from two lanes (PCI Express x2) in the previous model, a decidedly budget move, to four (PCI Express x4) in the SN550. That helps boost the top sequential read and write speeds from the SN500's 1,700MBps and 1,450MBps, respectively, to the SN550's numbers cited above. In contrast, the utility's 4K (or "random read/write") tests simulate typical processes involved in program/game launching... Inspire creativity with a one-month membership to Adobe Creative Cloud offering access to some of the world’s best creative apps and services such as Adobe Photoshop, Illustrator, Lightroom, Premiere Pro and InDesign. 4 Here the drive finally starts to falter against some other drives we tested, but it actually exceeds (by a smidge) its WD-rated speeds in sequential reads and writes.

Here the drives are put through a very important test for creative types. As anyone who regularly works in programs like Adobe Premiere or Photoshop can tell you, oftentimes the most excruciating part of the whole experience is the time it takes for the program to launch. There are a lot of elements that creative applications need to load.

An Evolution of the Blue

Okay, off of PCMark 10 and onto a more traditional measure. The Crystal DiskMark 6.0 sequential tests simulate best-case, straight-line transfers of large files. Let's get into the drag races.

Because the data is moved around frequently, some SSDs use a smidge of DRAM—which is much faster to access and read than NAND flash—to "map out" the data, and provide a reference point for the drive so it knows where everything is.

PCMark 10 Overall Storage Test

Finally come the copy tests. While at first these numbers might look low compared to the straight sequential-throughput numbers achieved in benchmarks like Crystal DiskMark 6.0 and AS-SSD, that's due to the way this score is calculated. Keep your imagination flowing as you create faster while maintaining low power consumption. With read speeds up to 3,500 MB/s 3 (500GB – 2TB 1 models), your system can run up to 5X faster than our best SATA SSDs so you can stay in your creative moment.

Habe mich dann für die 1TB entschieden obwohl diese keinen DRAM-Cache hat sondern es mit HMB (Host Memory Buffer) versucht zu kompensieren. One-month Adobe Creative Cloud trial³. Enjoy the collection of creative desktop and mobile tools for your creative projects— photography, graphic design, video editing, UX design, social media, and more. Beim spielen in meinen Rechner ist mir letztens aufgefallen das meine Samsung SSD 970 EVO Plus eine Temperatur über 65 Grad hat, trotz SSD-Kühler. Ich war völlig überrascht wie schnell diese SSD ist, zu keiner Zeit habe ich den DRAM-Cache vermisst, HMB macht einen sehr guten Job. Beim Gaming/Kopieren und runterladen von Steam liegt die Temperatur nun bei 50 Grad, super.Here the drive is strong in 4K random write speeds, and competitive in random read.
