Introduction and Drive Details

Small and Medium Businesses, or SMB enterprises, are having a difficult time sourcing the SSDs they rely on for functionality - especially high-capacity models, those over 15.36TB. Due to its power and footprint efficiency, 30.72TB SSDs are one of the most sought-after capacity points by SMBs. For those enterprises where datasets involve a significant amount of writes or programming, QLC is not the best option, more endurant TLC-based solutions are better suited for the best ROI.

Enter Sabrent's Rocket Enterprise 30.72TB SSD. Sabrent's highest capacity SSD stands ready to deliver super-efficiency for your enterprise. Its endurance is massive, checking in at over 56 petabytes written over 5 years. And because it's TLC based, it not only offers massively superior latency over its QLC based competition, but it is also inherently more power efficient because programming 3-bit flash requires less power than does programming 4-bit flash.

As stated, currently, one of the most sought-after capacity points is 30.72TB, making this capacity point especially difficult to source from the usual enterprise storage giants. Long waits and over-the-top pricing have become commonplace, and as such, many SMB enterprises are looking for alternative sources. This is where Sabrent is stepping in to fill the demand with its new Rocket Enterprise SSDs, which are available now and in high quantities and high capacities.

Now, let's dive in and take a close look at what Sabrent's new Enterprise offering can do for you by the numbers.

Sabrent's Rocket Enterprise Series is available at capacity points ranging from 1.92TB -30.72TB in the 15mm 2.5-inch U.2 form factor. The drive we have in hand for this review is 30.72TB - Phison PS5020-E20 16-channel controlled and arrayed with Hynix 3D eTLC flash. These SSDs are compatible with major operating systems such as RHEL, SLES, CentOS, Ubuntu, Windows Server, and VMware ESXi.

Test System Specs & Enterprise Testing Methodology

Enterprise SSD Test System

Prior to the AI revolution, datacenter SSDs' normal operating range would typically never exceed QD32. With AI data pipeline storage being directed by GPU, high queue depth performance has become paramount. Queue depths in the thousands are now commonplace, which is why we've changed our test platform, methodology, and operating system. Our charted upper queue depth range has been revised from QD256 to QD4096 for random data and up to QD1024 for sequential testing.

Testing Methodology

TweakTown strictly adheres to industry-accepted Enterprise Solid State Storage testing procedures. Each test we perform repeats the same sequence of the following steps:

1. Secure Erase SSD
2. Write the entire capacity of SSD 2x (2 loops) with 128KB sequential write data, seamlessly transition to the next step (sequential testing skips step 3)
3. Precondition SSD by filling the drive twice with 4K or 8K random writes
4. Run test-specific workload with a 30-second ramp up for 5 minutes at each measured Queue Depth, and record average result

Benchmarks - Sequential

128K Sequential Write/Read

31

We precondition the drive using 100 percent sequential 128K writes at QD256 using 1-thread for 2-drive fills, receiving performance data every second. We plot this data to observe the test subject's descent into steady-state and to verify steady-state is in effect as we seamlessly transition into testing at queue depth. A steady-state is achieved after 1-drive fill. Average steady-state 128K sequential write performance at QD256 is approximately 6,200 MB/s.

31

31

Sabrent specs its Rocket Enterprise 30.72TB SSD as capable of delivering up to 6,200 MB/s 128K sequential write throughput. This is exactly what we are getting, so the factory spec seems to be right on the money. The performance curve here is among the best we've encountered coming from a PCIe Gen4 SSD. Notably, it's better across the board here than the ION 6500.

31

31

The drive is factory spec'd for up to 7,000 MB/s 128K sequential read throughput. We are hitting up to 7,520 MB/s, so factory spec here is on the conservative side. At lower queue depths the drive is running behind much of its competition, however, at queue depths of eight and higher, our contender leaps ahead of most of the drives featured on this chart. Its performance curve is identical to that of its 15.36TB sibling.

Benchmarks - Random

4K Random Write/Read

31

We precondition the drive using 100 percent random 4K writes at QD256 for 2-drive fills, receiving performance data every second. We plot this data to observe the test subject's descent into steady-state and to verify steady-state is in effect as we seamlessly transition into testing at queue depth. A steady-state is achieved after 1-drive fill. Average steady-state 4K random write performance at QD256 is approximately 230K IOPS. The pattern observed here is exactly what we love to see. Its tight and consistent pattern attests to its high QOS design.

31

31

Sabrent's 30.72TB contender is rated at up to 180K for 4K random write IOPS. We are seeing up to 230K, which is significantly better than the 15.36TB model. Additionally, we do appreciate how consistently the drive performs across all measured queue depths and the fact that it outperforms the P5520 across the board.

31

31

Factory spec here is up to 1,600K IOPS at QD256. We are getting 1,800K IOPS at QD256 with our configuration. This additional 200K IOPS over factory spec is great to see. The drive's performance curve here is among the best we've recorded with a flash-based PCIe Gen4 SSD. Impressive.

4K 7030

31

31

Here we find our test subject again outperforming the 15.36TB model as well as the P5520 across the board. Excellent.

4K 5050

31

31

Exactly what we witnessed at 4K 7030, we again find our test subject delivering more than its 15.36TB sibling. This time, however, it is running neck and neck with the P5520.

8K Random Write/Read

31

We precondition the drive using 100 percent random 8K writes at QD256 for 2-drive fills, receiving performance data every second. We plot this data to observe the test subject's descent into steady-state and to verify steady-state is in effect as we seamlessly transition into testing at queue depth. A steady-state is achieved after 1-drive fill. Average steady-state 8K random write performance at QD256 is approximately 118K IOPS. The pattern observed here again is exactly what we love to see. Its tight and consistent pattern attests to its high QOS design. Impressive.

31

31

We expect 8K random to track pretty much the same as 4K random here, just at a lower IOPS rate because it's moving twice the amount of data. Here we find our test subject delivering exactly half the IOPS it did at 4K. Again, it bests both its smaller-capacity sibling and the P5520.

31

31

At low to mid-range, Sabrent's new enterprise SSD is running in the middle of the pack, at the top end it's delivering as good as it gets for a PCIe Gen4 SSD. It's running identical with the 15.36TB model and that's outstanding.

8K 7030

31

31

8K 7030 is representative of a common database workload. At the low end of the queue depth ladder, our test subject delivers average to above average performance. At mid-range queue depths and beyond, performance is somewhat lackluster, but again better than the 15.36TB model.

8K 5050

31

31

Everything just stated about its performance curve at 8K 7030 applies here as well.

Final Thoughts

There is a lot to like about Sabrent's highest-capacity enterprise SSD. The drive is inherently super-efficient, being arrayed with 32TB of TLC flash. The drive offers exceptional consistency, which is a direct byproduct of its high QOS delivery, as demonstrated by our preconditioning charts. The drive excels when serving sequential data to the host, doing so as well as we've seen coming from a PCIe Gen4 SSD.

Best of all, Sabrent's 30.72TB high-capacity Rocket Enterprise SSD is readily available with little to no lead time involved, in fact, Sabrent is already shipping to its customers.

31

It's readily available, inherently efficient, exceptionally consistent, delivers plenty of performance, and is backed by a 56 PBW 5-year warranty. Sabrent's 30.72TB Rocket Enterprise SSD is TweakTown Recommended.
