AnandTech 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.

ATSB - Heavy (Data Rate)

The Intel SSD 545s shows substantial improvement over the 540s in average data rates for the Heavy test. The 545s is not quite able to compete against Samsung as was the case for The Destroyer, but it comes much closer than its predecessor.

The 545s also fares far better when the test is run on a full drive than the drives that use the previous generation 32L 3D TLC (ADATA's SU800 and Crucial's MX300). Both of those drives beat the 545s when the test is run on an empty drive, but suffer a huge performance loss when the drive is full.

ATSB - Heavy (Average Latency)

The latency measurements for the Intel 545s on the Heavy test tell a similar story to the average data rates. Intel is now in the same league as the other 3D NAND SSD, though still in last place. When the test is run on a full drive, the Crucial and ADATA drives fall apart and average latency spikes to the 2–4ms range while the latency of the Intel 545s is unaffected and remains well below 1ms.

ATSB - Heavy (Average Read Latency)ATSB - Heavy (Average Write Latency)

The read latency of the older Intel 540s is not too far behind the 3D NAND drives and it handles being full with no trouble, but its write latency in either case is almost twice as high as the 3D NAND drives. The biggest improvement of the Intel 545s comes from cutting that write latency. The read latency also improved enough to surpass the Crucial MX300.

ATSB - Heavy (Power)

The energy usage of the Intel 545s during the Heavy test has it essentially tied for second place with the Samsung 850 EVO, while the Crucial MX300 has the clear lead when the test is run on an empty drive. The MX300's advantage disappears when the test is run on a full drive and the SU800's energy usage almost doubles.

    Thanks for the details.

    Guess with this launch, we'll soon have confirmation that they are using string stacking.

    Seen this?

    So you had the Toshiba NVMe 64layer drive first but bumped it from your testing so you could announce Intel was first to market?

    Great to see some competition for the 850 Evo. Kind of ironic that it should come from Intel, who aren't usually known as the underdogs that provide much needed competition...

    "On some tests, the Intel 545s appears to be the first serious challenger to the Samsung 850 EVO's combination of high performance and good power efficiency in a TLC SATA SSD."

    Well now I'm interested. Fingers crossed for decent pricing.

    Definitely, if it can come under the 850 Evo, I'll have my eye on this drive.

    Oh Intel, how far have you fallen. You used to be the innovator, the forerunner.
    Now you're playing catch up and barely managing at that.
    What happened?

    They realised it was more profitable to sell tiny dual and quad core CPUs for hundreds of dollars, add a pin to the socket every few years to sell a new chipset, and add 100MHz to the top end model and sell it for an extra thousand dollars.

    And add four extra cores for more than twice the price of the original. The X series of CPUs and chipsets were completely scams, up until Ryzen happened.

    Any idea, at all, on what form factors the m.2 versions will be available in, at launch, or the possible capacities that will be available for those form factors?
