The ADATA Ultimate SU750 1TB SSD Review: Realtek Does Storage, Part 1
by Billy Tallis on December 6, 2019 8:00 AM ESTAnandTech Storage Bench - Heavy
Our Heavy storage benchmark is proportionally more write-heavy than The Destroyer, but much shorter overall. The total writes in the Heavy test aren't enough to fill the drive, so performance never drops down to steady state. This test is far more representative of a power user's day to day usage, and is heavily influenced by the drive's peak performance. The Heavy workload test details can be found here. This test is run twice, once on a freshly erased drive and once after filling the drive with sequential writes.
The empty-drive performance of the ADATA Ultimate SU750 on the Heavy test approaches that of the mainstream SATA SSDs, but when the test is run on a full drive its performance drops down to be on par with the other entry-level drives: the Toshiba TR200 DRAMless TLC SSD, and the Samsung 860 QVO with QLC NAND.
The average and 99th percentile latency scores repeat the same story: the SU750 handles the Heavy test well when run on an empty drive, but when full it struggles like other entry-level drives.
The average write latency for the SU750 on the Heavy test shows a much larger full-drive performance penalty than the average read latency scores, but in either case it comes out well ahead of the other two entry-level SATA drives.
The 99th percentile read and write latencies from the SU750 are both competitive with mainstream SATA drives when the test is run on a full drive. When full, the 99th percentile read latency on the SU750 takes a hit that makes it slightly slower than the Toshiba TR200. For writes, the SU750's QoS is hurt quite a bit more, but the TR200 shows just how bad things could have been.
Power consumption is again pretty high for the SU750, especially for the full-drive test run. The two NVMe drives somewhat obscure the big gap that separates the SU750 and 860 QVO from the rest of the SATA SSDs.

I didn't even want to bring up Killer XDdeil - Monday, December 9, 2019 - link
Well ONLY cards where I lost sound due to broken drivers is realteck. AND coincidentally ONLY network adapter that was supposed to do full gigabit, and stopped negotiation at 10 mbps was also realteck.they can do decent hardware, but soft from them is crappiest as possible.

My 1st hand experience with Realtek dates back to Pentium 4 era. And it was so bad then I am still avoiding anything done by them in almost panic mode. Maybe they improved since then, but I am still not in state of mind to spend few $ to try.Gigaplex - Saturday, December 7, 2019 - link
Intel was terrible in the Pentium 4 era. Do you also avoid Intel in the same way?HollyDOL - Saturday, December 7, 2019 - link
Intel never had problems with functionality or output quality. For many scenarios you had better perf/$ on Athlons, but you didn't have problems having multiple computers on same network with Intel NIC having same MAC, lousy sound quality infested with noise or very low NIC performance.So no, I am not avoiding Intel same way since I never had remotely similar problems with them.

They weren't that bad. After building a neighborhood network (100Mbps and constantly saturated with Direct Connect P2P transfers) with thousands of clients (perhaps in the 5 figures or close to), 99.9% being Realtek network chipsets I'd say many of the issues are a bit overstated. Sure Intel was (is?) better but other than crappy support in Linux at that time, there was nothing out of the ordinary bad with Realtek. Not one MAC issue, not very low performance.I'm sure those thousands are not representative of all Realtek sales but I think there must also be some bias in there where the multitude of reports on forums makes you think it's an absolute rule that they were crap. Sound cards... dunno, had them on many PCs but rarely cared about the sound back in the day.

Terrible performance maybe. But Intel has always been fairly reliable. They've had a few minor chipset recalls, and the embarrassing, but very limited Pentium III recall, but on the whole they have traditionally had less errata than AMD and quite frankly their chipsets were always the gold-standard of PC's. Their network controllers are among the best in the world.PeachNCream - Friday, December 6, 2019 - link
ADATA has gotta get out of this town, out of this town and out of L.A. - with those prices. TRIM them to around $80 for 1TB and they will have a Solid pricing State to Drive sustained sales.bananaforscale - Friday, December 6, 2019 - link
Realtek does Dallas Semi?Lord of the Bored - Friday, December 6, 2019 - link
No, Maxim did Dallas Semiconduotor.
