SanDisk’s SMART Storage Systems CloudSpeed 1000 and 1000E Server Grade SSD Review

ADVANCED WRITE TESTING

As we talked about in our Micron P400m SSD Review, SSDs have different performance states. Since the SMART CloudSpeed 1000E is an enterprise SSD, we will focus on steady state performance.

With the following tests, we stressed the drive using random 4KB write workloads across the entire span for at least 24 hours. This is more than enough to achieve steady state. The following graph is showing the latency and IOPS across an 11 hour span.

SMART_1000E-LAT_MIN

The above graph shows the 1 minute averages over 11 hours.  So far so good.  The 1000E delivers a very tight distribution of IOPS and latency.  You can see some periodic events happening (garbage collection, wear leveling, etc.), but they have very little impact on the overall performance.

SMART_1000E-LAT_IOPS

When we zoom into the last hour and look at the per second average, you can see that there really isn’t anything to worry about in terms of maximum latency.  Even a very short, 1 second average is enough to obscure the maximums. What that tells us, is that only a handful, if even that, of the 30K operations per second, are reaching the 60ms level.

We have always admired the performance consistency of SMART SSDs at steady state, the 1000E is no different.

Why is it that “Enterprise” SSDs do not have SAS interface?
Without SAS “Enterprise” devices should really be called “Prosumer”.

That’s a heck of a jump considering the large number of enterprise systems that utilize the SATA interface. I am not aware of many prosumer sales for a product such as this, however sales of the original 500 version would have justified the initial investment for development of the drives.

One step at a time…

At SNIA’s IOPS test, which QD did u used for the test? 4? 16? 32?? 128???

ki – We use a QD of 32, unless otherwise noted. I’ll make sure to call that out next time.

Very slowly recognition In Lenova T61, difficult to use it, Have you any idea about this problem ?

How did you do secure erase? I had one, but got failure message for secure erase. thanks. I can do secure erase for other drive including some Datacenter drives. thanks.

You need to put the computer to sleep and then wake it up, otherwise its stuck in freeze state.

But if frozen, I get the message that the drive is frozen. But this case, I just got : secure erase not completed successfully. I checked this drive by Intel RST, but not frozen status actually. Any advice will be great for me.
