Mixed Random Read/Write Performance

The mixed random I/O benchmark starts with a pure read test and gradually increases the proportion of writes, finishing with pure writes. The queue depth is 3 for the entire test and each subtest lasts for 3 minutes, for a total test duration of 18 minutes. As with the pure random write test, this test is restricted to a 16GB span of the drive, which is empty save for the 16GB test file.

Iometer - Mixed 4KB Random Read/Write

On the mixed random I/O test the Intel 540s has a stark advantage over almost all other planar TLC drives, and is close to the low-end MLC drives and SanDisk X400.

Iometer - Mixed 4KB Random Read/Write (Power)

Power consumption is middle of the road, so the Intel 540s comes out at ahead of most of the TLC drives in terms of efficiency, though the SP550 is not far behind.

The performance of the Intel 540s never dropped as the proportion of writes in the workload increased, but it also didn't show the common big jump in performance during the final pure-write phase of the test.

Mixed Sequential Read/Write Performance

The mixed sequential access test covers the entire span of the drive and uses a queue depth of one. It starts with a pure read test and gradually increases the proportion of writes, finishing with pure writes. Each subtest lasts for 3 minutes, for a total test duration of 18 minutes. The drive is filled before the test starts.

Iometer - Mixed 128KB Sequential Read/Write

The mixed sequential I/O performance of the Intel 540s is significantly improved over the SM2256 drives, but that still only brings it up to par for planar TLC.

Iometer - Mixed 128KB Sequential Read/Write (Power)

The power usage of the Intel 540s is relatively high, so it doesn't have great efficiency even by TLC standards.

The Intel 540s is both faster and more power hungry than the SP550 at every point during this test. Performance still doesn't bounce back appreciably with the pure writes phase of the test, which keeps the average down despite the good read performance at the beginning.

    I am ... Amazed that Intel would dirty their brand name like this. Truly a terrible controller, terrible flash, and a terrible idea.

    Intel has a brand name that generally speaks to quality parts. They should never have dabbled in the arena of TLC.

    Reveals optane, releases mediocrity... come on.

    I actually worked on this for a short time last year, and I can say - working with SMI definitely is not as easy (at least for Intel) and was certainly more frustrating than developing in house.

    Any reason they didn't label a drive with this level of performance a 300 series drive?
  • Drumsticks - Friday, June 24, 2016 - link

    No idea, honestly. I think everything is just a 5xx SSD now (at least the SATA stuff). I think it's priced well above what I was expecting it to be priced at though, tbh.

    300 series had 3y warranty.

    HERE COMES THE SSD MEMES!

    >Muh MLC!
    >Muh endurance!
    >Muh data retention!
    >Muh reliability!
    >Muh random I/O!
    >Muh this drive isn't exactly what I want in my PC, so instead of using PC Part Picker to find a suitable drive for my incredibly critical tastes, I'm going to post a comment on a news article expressing how disgusted I am by how this drive isn't up to _MY_ standards.

    FUN FACT: Did you know that companies design products for people besides yourself?
  • b4bblefish - Thursday, June 23, 2016 - link

    Meh... it's not that they make products for people besides us. It's that for the price it's a horrible deal. You can buy better more reliable drives for a lot cheaper especially if it's targeting the entry level consumer market. So why bother entering this segment and offer something without any value?
  • JoeyJoJo123 - Thursday, June 23, 2016 - link

    Because these drives are likely aimed at bulk government/corporate purchases, not really for consumers as the price/performance ratio is terrible. Government/corporate entities will end up buying bulk, even when the price isn't the best available, from what the business analysts approve as reputable companies; not because it's a wise purchase from an IT perspective.

    I guarantee you this: It's got an Intel sticker, so it'll be bought in droves by people who don't know, even if it sucks. See: Pentium 4.

    And secondly, nobody should ever care for brand image. Every brand releases crap products from time to time. Some brands do this more often than others. Always evaluate products on an individual level, not because they happen to come from some "reputable" brand.

    I agree with most of your post. However, you went off the rails with regard to brand image. Yes, you shouldn't buy based on brand image alone. However, all things being equal, brand reputation does come into play. Companies earn a reputation, for better or worse, based on the quality of the product they produce. Completely disregarding that history isn't very good advice.
