The HP S700 And S700 Pro SSD Review
by Billy Tallis on September 7, 2017 9:00 AM ESTAnandTech Storage Bench - Light
Our Light storage test has relatively more sequential accesses and lower queue depths than The Destroyer or the Heavy test, and it's by far the shortest test overall. It's based largely on applications that aren't highly dependent on storage performance, so this is a test more of application launch times and file load times. This test can be seen as the sum of all the little delays in daily usage, but with the idle times trimmed to 25ms it takes less than half an hour to run. Details of the Light test can be found here. As with the ATSB Heavy test, this test is run with the drive both freshly erased and empty, and after filling the drive with sequential writes.
On our lightest ATSB test, the average data rate scores are not as widely variable and higher capacity doesn't always translate to a clearly higher score. The empty-drive performance of the HP S700 is slower than everything else regardless of capacity, but not by a huge margin. When the drives are full, the HP S700's performance drops precipitously, but the 512GB HP S700 Pro retains more performance than even Crucial's drives.
None of these drives has a problem with average latency when the Light test is run on an empty drive. The ADATA SU800, HP S700 and the smaller two capacities of the S700 Pro show much higher average latency when full, but on a test this light the worst scores are still in the low millisecond range. The 99th percentile latency scores paint a similar picture of all the drives being fine until they're full, and the 512GB S700 Pro handles being full quite well.
The 120GB S700 is the only drive in this bunch where average read latency exceeds 1ms when the test is run on a full drive. Average write latencies can climb to over 1ms for several drives, and the 120GB S700 breaks 5ms in the worst-case conditions for the Light test.
The 99th percentile read and write latencies are all in the low-millisecond range when the Light test is run on an empty drive. With the drives full, the worst case is again the 120GB S700, with thirty times higher 99th percentile write latency. But since this is still only 100ms, even this slowest drive doesn't produce noticeable pauses during ordinary use for light workloads.
All three HP S700s top the energy efficiency charts, and the S700 Pros aren't far behind. Energy efficiency is worse when the test is run on a full drive, but the result is that the S700 Pro ends up at the top instead of the S700. Before TLC NAND took over the mainstream SSD market, Silicon Motion's controllers were known for great efficiency. HP's drives show off Silicon Motion's efficiency much better than the ADATA SU800 did.

I understand that but where it'll lead us to? Most of things cost much more in the US compared to the same in China - from gasoline to food. A Chinese can cover his living expenses with just $1000/month while it takes at least twice that much for an American. Keep on rising the minimum wage will not solve the problem because we will be left with nothing to produce. Something's really messed up here.demMind - Monday, September 11, 2017 - link
sonny.. US Companies can afford to pay wages in the US. They just don't want to because executives love their year-over-year bonuses and dividends to grow. So no, prices haven't gone up because of cost of labor, they've gone up because each of us wants as much as we can get for as little extra effort as possible.Fujikoma - Thursday, September 14, 2017 - link
The price wouldn't be that much more. That extra labor savings is balanced by less efficient use of labor, material waste, shipping costs, increased counterfeit products, higher CEO pay and stock payouts if they exist (Apple is a good one for this). When companies moved to China, they did not lower their prices from cheaper labor. They lined their pockets with the extra cash. I worked for over a decade with a major electronics manufacturer invested heavily in China. Nothing but a headache for such a slim margin. That was with a 50X price margin on one of their highest volume products compared to a 12X price margin with the Mexican produced product (selling price relative to claimed materials + labor + storage + packaging + advertising + everything else involved). The higher margin is offset by shipping, defective/poorly made product, counterfeit product and material waste from poor manufacturing setup.As to the cheaper labor, that's because the U.S. allows product made from next to slave labor AND product made in environmentally damaging conditions to be imported into this country. Why do you think China has a pollution problem (aside from coal)... less regulation compared to Europe, Canada, Japan and the U.S.

Sonny, you realize Lenovo lost the crown 2 years ago? They held the #1 spot for 14 quarters. HP has held the #1 spot for 39 quarters since 2006 when they took it from Dell.Nobody is hurt...except the Fortune 500 companies that blindly bought into Lenovo based on price, only to have their IT dept advocate for change almost immediately. Which aligns perfectly with the 3 year corporate product cycle and the amount of time Lenovo held the #1 sales edge in North America.
I'm an IT director, I know first hand the outcry my community had over Lenovo, and not just in relation to superfish.

I don't stand any of these big players HP, Lenovo.... It's all rip off, Lenovo's licensing is too complicated (can't activate features you paid for on hardware that they consider obsolete) and then on HP side plenty of similar crap. You almost feel bad for asking for something you own/deserve/paid.... I love SunMicro, chenbro, clean LSI or Adaptec works with everything. What HP SSD, that one will be backed by warranty only if attached to their mobo, or whatever other stupidity...Flunk - Thursday, September 7, 2017 - link
Marketing terms are always meaningless without context. You always need to read the specs behind the glossy advertising to know what you're buying. I don't see that changing any time soon.MajGenRelativity - Thursday, September 7, 2017 - link

I'm shocked by the price. Dramless, with those specs, should be $70, top, for the 240GB.Why in the world would I spend no less than $116, when the EVO sells for $90?!?!?!

Just what I was thinking. Pricing on these are ridiculous. They have a bit more storage size, but so does the Crucial MX300 and it's also way cheaper and faster!Samus - Thursday, September 7, 2017 - link
The MX300 is pretty much the only economy drive to consider outside of an 850 EVO IMHO. Even if these sell for half the retail price, they aren't worth it. You can just pickup an old M500 on eBay (or even an OEM Intel 520/530) for half these prices and have similar performance.
