List Of Best SAS SSDs What You Can Buy For Your NAS, Servers & Data Centre

Report Data Collected On: 1/Nov/2018

In an article a little while, ago, we discussed the evolution of the SSD, starting from the 2.5-inch SATA version to the tiny little stick-of-gum-sized NVMe SSDs with the fastest data transfer speeds to date.




The SATA interface still provides the best value for money, but for best performance, NVMe is, as yet, undefeatable;

But there is something in the middle that tends to be glossed over by almost everyone (but not us) which is still worthy of consideration.

The SAS interface;

The SAS was sort of the middle-ground between the SATA and the NVMe, in that it can be used by both SSDs and HDDs, and was developed mid-way through the SSD dev cycle and immediately made near-obsolete by the NVMe drives that came along right after.

For this reason, they’re not as popular – among SSDs or HDDs;

But there’s one demographic which still has a high demand for these things, and is a major part of the reason why they haven’t disappeared completely: Servers and mainframes.

A lot of servers and network admins still prefer SAS SSDs, and you can’t blame them, because this thing was specifically designed for that.

The SATA is a general-purpose interface, which the SAS was never meant to replace, but built as a more expensive, more powerful and faster successor to be used in critical server applications. And, to be completely fair, it achieved all these goals, and does it jobs impeccably and without hassle.

Properly specced SAS SSDs will give you that precise and powerful response time without clogging up your server. Their performance on average will be on par with, or just above Enterprise HDDs of the same range, that we’ve discussed before.

As usual, let’s take a look at the top of these available in the market;



So, Let’s See How Many Best SAS SSDs Are Available For NAS/Servers:
