Toshiba PX04S Enterprise SSD Review Discussion

7 posts in this topic

The Toshiba PX04S are 2.5” enterprise SAS SSDs that provide massive performance and enough different models to suit most use cases. The mid-endurance model we tested showed chart-topping performance throughout, setting a new watermark for SAS SSDs.

Very impressive.

We're talking PCI-E SSD like speeds here on this monster. Do you think they will release a variant for U.2 as well?

We can't comment on roadmap as we've actually seen this one pretty far out. I do think it's logical though that Toshiba sees what others see, and that SAS and SATA is not the only interface that will have significant marketshare in the enterprise. Question really is how big are the others and where/when does it make sense to offer and support products in those markets.

Why aren't SATA SSD manufacturers upping their clock speeds to 12 Gb/s too?

Even though SATA SSDs are necessariliy single-ported (as compared to SAS double-porting),

an 8G clock is already a standard feature of the PCIe 3.0 specification, and

12 Gb/s RAID controllers are now available from a number of reputable vendors

e.g. Areca, LSI, Adaptec, ATTO, Intel etc.

Moreover, SAS backplanes are designed to work with SATA drives.

What am I missing here, please?

What we hear is that SATA isn't worth investing in and most vendors see it going away entirely in the client space first, within the next year or two. NVMe will be the clear leader in all new client systems going forward. This includes to a lesser extent IoT devices as well. On the enterprise side, we'll probably see the same thing on a slightly slower cadence.

How does this Toshiba compares to new NVME drives, e.g. : Samsung SSD 960 PRO 2TB, M.2 (MZ-V6P2T0BW) 

We don't typically run the same set of benchmarks on client drives, not sure anyone is cross shipping an expensive SAS drive with the 960 Pro for instance.
