## Description

Boost your NAS system's performance and responsiveness with the WD Red SA500 NAS SATA SSD. Your NAS system is always on, making a reliable drive essential. Unlike standard SSDs, WD Red NAS SATA SSDs are specifically designed and tested for 24/7 usage. Their endurance and efficient caching makes them ideal for demanding applications.

Review: Early days, but so far, so good. - I'm using a number of WD Red SA500 4TB NAS drives in a ZFS pool consisting of 6 mirrored vdevs. Overall pool performance is great, though average single disk write speed observed during two resilvering operations is only around 200 MB/s. (I've never seen it go above 380 MB/s.) It's not clear to me whether that's the sustained write speed of this drive or if there's a bottleneck (or deliberate throttling) elsewhere. As mentioned in the headline, it's still early days - the pool has only been in operation for a few months. Within the last few days ZFS started showing checksum errors for one of the Samsung EVO 860s that are also in the pool. I replaced it with an SA500. I'll try to remember to update this review over time to note how the SA500s are faring. Update - 2020-09-17: I now have eight of these SSDs. No problems so far. Update - 2021-12-13: In May, 2021, my ZFS pool with eight of these drives (plus eight Samsung drives) faulted one of the SA500 SSDs due to write errors. I replaced it with another SA500. Earlier, back in July of 2020, one of the Samsung drives failed too; I replaced it with a SA500 (as it was cheaper at the time). So far, in that pool, I've had two drive failures; one 4TB Samsung 860 EVO and one 4TB WD SA500. I'm still running the pool with eight Samsung drives and eight WD drives, with no real preference aside from whichever is least expensive when I need a new one.
Review: Better performance for your NAS - They were an easy replacement for my 4TB Seagate QNAP NAS drives. I've had 4 of these SSD's running in my TVS-471 for 3 months and they are fast, reliable and silent! I know they are expensive compared with Hard Disks, but the additional speed and silent operation makes them worth it. Using MKV for movie transfers to my NAS are much faster and Plex is less likely to transcode to a lower resolution. 4K movies are delivered cleanly to my various Samsung and LG big screens. I also upgraded my QNAP from an i5 to an i7 and added two M.2 1Tb drives for caching.

## Features

- Storage optimized for caching in NAS systems to rapidly access your most frequently used files.
- Superior endurance can handle the heavy read and write loads demanded by NAS, giving you the reliability you need in a 24/7 environment.
- Purpose-built for NAS with proven Western Digital 3D NAND to deliver maximum SATA performance to both home and business users.
- Reduces latency and improves responsiveness for oltp databases, multi-user environments, photo rendering, 4K and 8K video editing, and more.
