- Phison X200Z writes the whole drive every 24 minutes nonstop
- Provides record-sized endurance and performance with 60 DWPD capacity
- Tweactown calls it the most powerful flash-based SSD ever tested
Tweattown Has delivered his first practical look at Phison Pascari X200Z 3.2TB Enterprise SSD, and-spoiler alarm-it was blown away.
Built with SLC flash and ran over a PCIe Gen5 X4 interface, the X200Z boasts a writing endurance classification of 60 drive writing per day. Day (DWPD) that translates into an amazingly fully driven write every 24 minutes.
As Jon Coulter of Tweattown Puts it, “Phison’s Pascari X200Z 3.2TB SLC Cache SSD is also the highest capacity, lowest latency and most endurant flash-based SSD of its kind we’ve ever encountered.”
The best ever seen
The X200Z is built for extreme durability in demanding cache roles, especially in front of QLC -ARRAYS.
It buffer randomly Write workloads, converting them into sequential data and leading them to slower, more fragile QLC layers, improves speed, reliability and overall life of the storage system.
Coulter notes, “The 3.2TB model we have in the hand is rated at 60 DWPD or a mind-inflating 350 petabytes of endurance. Incredible.”
The drive also shines on performance. When testing it exceeded its factory specifications everywhere. Sequential read flow hit 15,026 MB/s – Breaking Tweattown Lab Records – while writing characteristics came at over 10,200 MB/s.
In random workloads, the X200Z hit up to 2800K IOPS and showed strong consistency across all fleshingbuds.
Coulter was impressed with the performance curve: “Its depth performance here is amazing.”
He adds, “We knew it would be good, but we didn’t expect the drive’s mixed workload performance to be so amazing. By far the best we’ve ever seen.”
Phison positions his Pascari line as a business degree and offers flexibility in U.2 and E3.s Form factors and support for double portion configurations. The Pascari X200 series already has design gains across data centers, video platforms and HPC workload.
Coulter concludes: “Phissons Pascari X200Z 3.2TB SSD is easily the most powerful flash-based SSD we’ve ever tested.”
