ADATA Ultimate SU630 Drive Review: Trying 3D QLC

In mid-November, ADATA introduced a new line of SSDs, the Ultimate SU630, which uses 3D QLC flash memory with a 4-bit cell structure. Chips of a similar architecture have been used for some time for specific enterprise SSDs, but for the mass market this is still a curiosity. In the future, QLC memory will be actively used for affordable entry-level drives, as well as high-capacity SSDs, so we were already interested in evaluating the capabilities of such devices using the ADATA Ultimate SU630 480 GB as an example.

The ADATA Ultimate SU630 uses 64-layer 3D QLC flash memory chips and the new Maxio MAS0902A-B2C controller from Maxiotek. It is worth noting that ADATA is not afraid to experiment, mastering the original SSD platforms, without waiting for their mass adoption by other manufacturers. The market for solid-state drives is now very competitive, therefore, in order to stay afloat, you have to take certain risks.

Many people have probably already heard about the modest capabilities of QLC-based devices. What kind of performance does ADATA promise for the new SSDs? Depending on the capacity of the model, the read speed is declared at the level of 520 MB / s, linear write — 450 MB / s. In this regard, the performance is almost the same as that of mass-produced SSDs on TLC. As for the speed of working with 4K blocks, here the developers promise about 65,000 IOPS when writing, while the number of I / O operations when reading data depends on the capacity of the SSD: 40,000 IOPS for models on 480 and 960 GB and 30,000 IOPS for 240 GB drives. The indicators are quite modest, but generally acceptable for entry-level devices.

In the case of 3D QLC-based drives, the potential reliability of the new SSDs is of particular interest. The multilayer arrangement of flash memory chips comes in handy here. The increased distance between the elements allows to improve wear indicators, partly compensating for the theoretically smaller resource of rewriting cycles of microcircuits with 4-bit cells. As a result, guaranteed data write volumes (TBW) are not as bad as one might expect. ADATA claims 50TB for the 240GB, 100TB for the 480GB model, and 200TB for the SU630 960 GB. Indicators typical for devices with planar TLC of the first wave. With a typical use of an SSD, even as a system drive, it is unlikely that you will be able to go beyond the specified limits in 2-3 years. At the same time, the manufacturer has set a warranty period of 2 years, instead of the usual 3 years for entry-level drives.

The SU630 feature set includes support for S.M.A.R.T., TRIM and NCQ. Also announced is a hardware implementation of LDPC ECC error correction and SLC caching technology to speed up data writing.

ADATA Ultimate SU630 480 GB (ASU630SS-480GQ-R)

We tested the middle model of the new 480 GB line — ADATA Ultimate SU630 480 GB (ASU630SS-480GQ-R).

The drive comes in a compact blister pack with a cardboard base and a transparent top cover that allows you to easily view the drive.

The device has the usual dimensions for a 2.5-inch device. The 7mm thick metal case is very light. The declared weight of the drive is only 47.5 g. The wall thickness is small, which is typical for an entry-level SSD. On the top panel there is a large sticker with the manufacturer’s logo and the name of the series.

On the reverse side, a sticker of similar size indicates the model name, format, connection interface, and a mention that the drive is made in Taiwan.

The case of the drive is collapsible, but on one of the side faces there is a protective sticker with a warning about the loss of warranty in case of damage. However, we couldn’t resist looking under the lid. We are still dealing with a new platform.

Very compact circuit board takes up no more than a third of the drive. The PCB contains the Maxio MAS09 controller02A-B2C. The 480 GB model uses two flash memory chips. On the reverse side, there are a couple more sites that are filled in the 960 GB SSD version.

3D QLC ICs are ADATA relabeled, so we can’t tell for sure what their manufacturer is. With a high probability, chips from Intel / Micron are used here. As you can see, there is no additional DRAM chip on the board.

It is interesting to try out a drive based on 3D QLC. Before moving on to SSD performance measurements, we note that the manufacturer suggests using the proprietary SSD Toolbox application for basic device management. Here you can evaluate the status of the drive, check the temperature, find out the status of S.M.A.R.T. and the amount of data already recorded by the drive. There are also options for completely clearing the SSD and forcing TRIM to start.

Performance

The first performance measurements show that we are dealing with an entry-level drive.

CrystalDiskMark is unexpectedly optimistic in terms of read/write linear speeds, but the performance with 4K blocks puts everything in its place.

Serial transfers in the AS SSD utility also exceed the advertised specifications. When working with small blocks, performance slows down, but in general, the performance is close to the announced. In multi-threaded mode, when reading, we get about 31,500 IOPS, and when writing, it has more than 75,000 IOPS. However, a slightly increased access time for write operations provides a relatively low final result — 724 points.

The data transfer rate for reading and writing does not depend on the degree of their compression.

In Anvil’s Storage test, the ADATA Ultimate SU630 480 GB received a good overall score. The utility registers good linear transfers and up to 75,000 IOPS on read / write 4K block operations.

However, the situation changes drastically as the amount of test data increases. Obviously, when you go beyond the SLC buffer, the write speed is significantly reduced. We have seen this while testing devices on TLC, but in the case of QLC, the situation is even more so. To appreciate this with a visual example, we ran some experiments in AIDA64.

Let’s start with a graph of reading speed. It’s practically a straight line at 510 MB/s. Quite good.

But with the recording, everything is much more interesting. The drive starts to save data very confidently at a speed of about 470-480 MB / s, but after about 30 GB of writing, the rate drops to 50-60 MB / s. The SLC buffer mode used allows the SSD to keep at a good level, but if the incoming data stream exceeds the cache size, then the data begins to be directly written at the speed available to chips with QLC cells. As you can see, during the process, the drive periodically tries to speed up the write, but since the test involves the transfer of a continuous stream of information, the SLC cache does not have time to clear, and therefore the speed drops again to the flash memory that is physically accessible to the chips. And in the case of QLC, it is quite low. It took more than an hour of real time to write even half of the 480-gigabyte drive.

To make the test even more practical, we tried to copy several video files with a total volume of about 39 GB from the system drive (Kingston A1000) to the ADATA Ultimate SU630. Here the situation turned out to be actually similar to what we observed in the AIDA64 test. When copying about 30 GB of data, we observed a write speed of 470 MB / s. Then the speed decreased by an order of magnitude — up to 40-50 MB / s. If in the case of TLC drives, we observed a decrease in write speed to 80–150 MB / s, then in the case of QLC, the decrease is even more noticeable. On the other hand, continuous writing of large amounts of data is generally not a typical model for using SSDs in a desktop system, so you may not even encounter such nuances.

To test the capabilities of the ADATA Ultimate SU630 under realistic conditions, we used a PCMark 8 drive test with load patterns across a range of applications.

The results obtained here once again confirm that the SSD in question belongs to the basic class of SATA drives with performance similar to those of starter devices based on TLC flash memory.

As regards the storage tank heating, there are no special remarks here. In rest mode, the temperature of the controller is 27-30C, after a long recording session, the chip warmed up to 55C — within the normal range.

Price and competition

With QLC flash drives, price remains the biggest concern. It is clear that these are entry-level devices, but their cost should be attractive enough to make the devices look competitive against the background of the base models already presented at TLC.

According to the manufacturer, ADATA Ultimate SU630 will appear in Ukraine approximately at the end of January. There are no final recommended prices yet. For the 480 GB model, the cost is tentatively indicated as “below UAH 2000”, but without specifics there is nothing to talk about here.

In general, the cost of SSDs has been systematically decreasing lately, and this trend is likely to continue in 2019. Already, budget SATA drives with a capacity of 480/500 GB based on TLC memory can be bought for less than 2000 UAH (~$72). This should be taken into account by manufacturers who rely on the success of their QLC models. There are a lot of competitors here. The same models of the SU650 series based on Silicon Motion SM2258 and 3D TLC can be distinguished from the ADATA range. Judging by the popularity rating on Hotline, among inexpensive devices from manufacturers, extremely cheap Patriot Burst, as well as Kingston A400, TEAM L5 Lite 3D, Crucial BX500 and GOODRAM CL100 are in high demand. All these models are already offered for less than 2000 UAH, so it will not be easy for new products to break into QLC. Even if the cost of such drives turns out to be lower by an impressive 20–30%, then, given the low prices of SSDs, in absolute terms this is a rather modest difference of $14–20 for a 480 GB model.
