The Intel SSD 600p (512GB) Review
by Billy Tallis on November 22, 2016 10:30 AM ESTMixed 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.
The 600p was slower than the Crucial MX300 on random writes but faster at random reads. On the mixed random I/O test, they average out to a tie.
Despite performing the same overall, the 600p used more than twice the power of the MX300. The SM2260 controller simply imposes far too much power overhead than is appropriate when paired with slow TLC NAND.

The 600p performs better as more writes are added in to the mix, but it doesn't spike in performance for the final all-writes phase of the test. This means its performance is much more balanced than many other drives that simply run up the score at the end.
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.
The faster-than-SATA read speeds of the 600p aren't enough to compensate for the poor write speeds, so it ends up scoring only slightly ahead of the budget SATA SSDs.
There is a clear separation in power consumption between the SATA and PCIe SSDs. For once, the 600p is the lowest power PCIe SSD, but it is still the least efficient due to its low performance.

As expected, adding writes to the mix drags down performance, though there aren't enough writes in the 80/20 phase to have much of an impact yet. It is a hallmark of low-end SSDs to see performance stay low through the end of the test, while high-performance SSDs typically have a U-shaped performance curve here.

They're in Bench now.Flying Aardvark - Friday, November 25, 2016 - link
I have the 1TB 600P and love it. I bought it knowing full well it wasn't a benchmark king. Don't care, low QD performance has hardly improved for quite some time. But at the price, for a 5-year warranty with 0.3% failure rate per year was a no brainer over the 960 EVO for me.I can't get it to slow down or stutter in my case and if you can, you should probably step all the way up to the Intel 750, heatsink intact and all.

I'm not sure now to formulate this correctly so as not to hurt the reputation of the product, but there's been a report of a 600p burning a motherboard's traces when installed via a DeLonghi adapter card. Anandtech, what could you comment on that issue? Came across it in a review for the 600p at a respectable decent online shop.crazyowl - Sunday, November 27, 2016 - link
Sorry, it was DeLock, not DeLonghi. The latter seems to be a houseware brand.Billy Tallis - Sunday, November 27, 2016 - link
Our testing showed the 600p to be relatively power hungry by the standards of M.2 PCIe SSDs, but it most certainly wasn't drawing enough current to be a danger to any equipment that is capable of safely powering other M.2 PCIe SSDs. Whatever you read about was likely the result of either a manufacturing defect in the board that was supplying power to the M.2 drive, or the result of improper installation leading to a short circuit. I've killed a motherboard through the latter means, but it was only due to the modifications I've made to facilitate measuring PCIe card power consumption.Xajel - Monday, November 28, 2016 - link
I would love to have an NVMe SSD, sadly my system is old (ASUS P8Z77 ) so, it's not able to boot from NVMe.. although nothing is wrong with the chipset it can do it, but ASUS never released any BIOS update, there's some unofficial mod's which can enable this but there's no guarantee it will work or it will brick.el-loc0 - Monday, November 28, 2016 - link
@Anandtec: what equipment do you use to measure power consumption?Billy Tallis - Tuesday, November 29, 2016 - link
For PCIe SSDs, I use a riser card from Adex Electronics with current sense resistors on the 3.3V and 12V supply lines. For SATA SSDs, I use a multimeter spliced into the power cable to measure current directly.el-loc0 - Tuesday, November 29, 2016 - link
Thanks for quick reply, Billy. Do PCIe SSD Draw Power from both lines, 3.3 V and 12 V? Do you use a current clamp or how do you measure on the riser card? Which multimeter do you use?SanX - Thursday, December 1, 2016 - link
Did Intel pay for this BS review?
