Intel SSD 750 PCIe SSD Review: NVMe for the Client
by Kristian Vättö on April 2, 2015 12:00 PM ESTAnandTech Storage Bench - Light
The Light trace is designed to be an accurate illustration of basic usage. It's basically a subset of the Heavy trace, but we've left out some workloads to reduce the writes and make it more read intensive in general.
| AnandTech Storage Bench - Light - Specs | ||||||||||||
| Reads | 372,630 | |||||||||||
| Writes | 459,709 | |||||||||||
| Total IO Operations | 832,339 | |||||||||||
| Total GB Read | 17.97 GB | |||||||||||
| Total GB Written | 23.25 GB | |||||||||||
| Average Queue Depth | ~4.6 | |||||||||||
| Focus | Basic, light IO usage | |||||||||||
The Light trace still has more writes than reads, but a very light workload would be even more read-centric (think web browsing, document editing, etc). It has about 23GB of writes, which would account for roughly two or three days of average usage (i.e. 7-11GB per day).
| AnandTech Storage Bench - Light - IO Breakdown | |||||||||||
| IO Size | <4KB | 4KB | 8KB | 16KB | 32KB | 64KB | 128KB | ||||
| % of Total | 6.2% | 27.6% | 2.4% | 8.0% | 6.5% | 4.8% | 26.4% | ||||
The IO distribution of the Light trace is very similar to the Heavy trace with slightly more IOs being 128KB. About 70% of the IOs are sequential, though, so that is a major difference compared to the Heavy trace.
| AnandTech Storage Bench - Light - QD Breakdown | ||||||||||||
| Queue Depth | 1 | 2 | 3 | 4-5 | 6-10 | 11-20 | 21-32 | >32 | ||||
| % of Total | 73.4% | 16.8% | 2.6% | 2.3% | 3.1% | 1.5% | 0.2% | 0.2% | ||||
Over 90% of the IOs have a queue depth of one or two, which further proves the importance of low queue depth performance.
The same trend continues in our Light trace where the SM951 is still the king of the hill. It's obvious that Intel didn't design the SSD 750 with such light workloads in mind as ultimately you need to have a relatively IO intensive workload to get the full benefit of PCIe and NVMe.

Insane performance, insane value. What else to say? Intel never loses a step and surprises at every turn.Peichen - Friday, April 3, 2015 - link
Sounds like there is going to be big form factor change coming to desktop computer in the next few years. Complete removal of 5.25 and 3.5" drives, M.2 and 2.5" drives taking over, CPU limted to <77W and video card to <250W.I should hold off replacing my still very good case until I am building a new computer in 3~4 years.

how would this drive compare with a 4 drive (samsung 850 pro 512), two card Sonnet tempo ssd pro plus arrangement? this set up is about $600 more, but 800GB larger and overall ~same $/GB @.82Freakie - Friday, April 3, 2015 - link
Maybe I'm just blind, but I don't see this 750 in Bench? Did someone forget to add it to Bench or is there a reason why it's not in there?boe - Saturday, April 4, 2015 - link
Those 10TB and 32TB SSDs can't come soon enough. I just hope they come down to an affordable price very soon as standard SSDs are still way to expensive per TB for any real storage needs.gattberserk - Saturday, April 4, 2015 - link
Can I ask why is the boot time so slow? For a drive this expensive this is not something that is tolerable.Is it possible to do a boot up timing with the fast boost function enabled? I wanna see how fast will it be as compared with other SATA drives using the same fast boot function.
The boot up time will be the last factor to decide if I wanna pull trigger on this one.

This drive is a beast and just raised the cost of my skylake-e build another 1000 dollars. Maybe an even better 2nd generation version will be out by then. Upgrading my gulftown to 8 core skylake-e flagship. 4.3ghz i7-980x will have lasted me 7 years by the time skylake-e comes out which is a pretty darn good service life. Convert the ole gulftown into a seedbox/personal cloud nas/htpc/living room gaming console. Kill all the oc's and undervolt cpu for the lowest voltage stable at stock and turn all the noctua fans down with ULN adapters into silence mode. It will be rough re buying a buncha parts I wouldn't of had to if I didn't keep the PC together but it's too good of a PC still to dismantle for parts. Will be nice having a beastly backup pc.My skylake-e build has really ballooned in price but this next upgrade should last a full decade with a couple gpu upgrades using the flagship skylake-e 8 core i7 + 1.2TB intel 750 boot drive + nvidia/amd flagship 16nm FF+ GPU. Basically like 3000 dollars just in 3 parts :(. Thats ok tho it brings too many features to the table pci-e 4.0 DMI 3.0 USB 3.1 built into chipset natively 10gbit ethernet natively up to 3x ultra m2 slots and the SFF connector used in this drive possibly thunderbolt 2 built in natively of course quad channel ddr4. Hopefully better overclocking with the heat producing FIVR removed guessing 4.7-5ghz will be possible on good water cooling to the 8 core.
Sorry got on a tangent. I'm just excited there are finally enough upgrades to make a new PC worth it. No applause for intel tho it took them 7 years to make a gulftown PC worth upgrading. I should see a nice IPC gain from i7-980x gulftown to skylake-e. I'll be happy with 50-60% IPC gain and 500 extra mhz on my 980x so 4.8ghz. I think 6x 140mm high static pressure noctuas in push/pull and a 420mm rad should provide enough cooling for 4.8ghz on 8 core skylake-e if the chip is capable. Goal is to push it to 5.0ghz tho and get 700mhz speed increase + additional 55% IPC gain.

Unfortunately Skylake e is not coming in another 2 years. There is no news of BW-E even, and that will be another year before Skylake will come in.By den, 750 would have been obsolette, esp with Samsung 3D NAND in NVMe PCIe SSD.

<$1/GB at 2400/1200 MBps R/W performance. What else you need !!Ethos Evoss - Saturday, April 4, 2015 - link
|I wud rather go for new Plextor which is 5 time cheaper and with same specs..
