Word of warning - it does not include the necessary mounting screw, so unless you're replacing an existing drive, you'll need to run to your local hardware store for a CM2x3-3.3 screw to mount it.
Reviews indicate it has an OK buffer size, with SamSung and even HP a little better.
However, the price is stellar, and it's still faster at any of its speeds than my prior device.
I was a little worried because of some claims that their new device was mislabeld.
The package I received had the safety tape cut already. I was worried.
I inspected closely, and everything was correct. No fingerprints, no damage.
When I installed the device, it said power cycles 2, power-on hours 0.
Hardware ID is Intel SSDPEKNW020T8, and size is 2 TiB.
Now that my concerns were assuaged, I used Macrium to clone.
Cloning from my old drive pushed 430GBytes in 45 minutes. Macrium claimed 1.3GB/sec.
Swapped the device, and re-enabled BitLocker, reinstalled Steam, etc.
So far, performance is great. It's been 3 days, and backups are fast, games load fast, etc.
I was on NVMe before, so I didn't expect to notice any difference.
I do. It's not as much as the difference from HDD to SSD, but it is like the difference between SATA and NVMe.
So, as a reminder, every few years, check performance for the next generation of SSDs.
If your system supports it, and you run any demanding workloads (VirtualBox/VMWare, gaming, etc),
then consider an upgrade.
UPDATE 2020-02-07: the performance is still about the same. 7300-7900 read iops and 9-15k write iops. Bumping up the queue depth brings that into the 30-90k range. Throughput is int eh 1300-1500 range on read, and 790-1700 range on sequential writes.
The main concern I had with this drive was that it was using QLC flash, which is pretty poor when it comes to write endurance. 200TB TBW for a 1TB drive is really low, but then I had to consider if I would ever reach that limit. I've been using a Crucial MX300 for the past two years with a very similar endurance rating (220TB) and I've only used 2% of that in those two years. Unless you have a really write intensive work load (like writing 100+GB every day for five years), then I highly doubt you'll ever come close to hitting that limit.
Once I realized that my fears of QLC were kind of irrational, I came to the realization that this drive is fantastic for what you pay. Any other 1TB NVMe drive is going to go for anywhere for 2-4x the price, while not providing a lot else in terms of features, speed, or capacity. The only thing you may get by paying more is a higher write endurance (from using TLC or even MLC flash) which I didn't find necessary, and slightly higher read and write speeds (which I also didn't think was important given how fast this drive already is).
Overall I'd highly recommend this drive to anyone who has a normal workload and wants to experience a significant bump in speed (and probably capacity) without spending a ton.
All that aside, if this is your first time installing an M.2 drive, you'll want to do your homework before you purchase one, as for example, I have an EVGA Z170 motherboard, and in order to activate the M.2 key M socket, it has to be done from BIOS, and doing so will disable SATA ports 4 and 5.
Anyway, it's all good and it's working well. I did have to purchase the Lenovo caddy adpater and cable because my T480 came with an older SATA HDD drive. I did this on purpose when configuring the laptop, planning on doing this upgrade myself, but I didn't realize that I would need to purchase the adapters (which added an extra $50 to the upgrade).
Anyway, if you're a little concerned about the length as I was, rest assured that it is 80mm and not 81mm.
Top international reviews
- Lowest cost per Gigabyte among all M.2 NVMe drives (May 2019)
- Very fast (mine goes up to 1.9 Gpbs in both read and write without using any kind of cooler), and the very fast (SLC) cache is a lot larger than the competition (from 280 GB to 24 GB depending on how full the drive is, versus the typical 20-40 GB on the competition)
- Reliable brand, easy to install
- If the drive is more than 75% full or you have (temporarily) filled-up the SLC cache, the drive can a bit slow (like a regular hard drive) while the SLC cache is getting restored to full speed (this is done automatically when the SSD is idle, and can be done manually using Intel's utility software). In my case this is not a problem since I purposely choose the larger (2 TB) version to ensure that I have plenty of free space and a large SLC cache.
- The drive's idle temperature for me (depends on many factors like airflow, ambient temperature, etc.) is around 35 degrees Celsius, but under heavy load (4 hours of data migration) it went up to 65 degrees Celsius. It is supposed to be fine operating at up to 70 degrees Celsius and I didn't see any performance slowdown (throttling), but I am planning to buy a small heat sink for the drive to keep it at a lower temperature during heavy loads (update: I did add a $10 heatsink and now, even under full load it doesn't go above 43 degrees C)
- A lot of people are complaining about the lower longevity of QLC versus TLC, but for the average user this drive will become obsolete long before the total lifetime writes have been exceeded. If however you do write more than 50 GB per day everyday (for video production or similar data heavy workflows), then this drive is probably not for you.
- Before buying, check your motherboard to ensure than it can actually take NVMe drives (and this particular size, which is 2280) as it can be confusing since they use the same M.2 form factor and connection with the SATA M.2 drives. Also check if using the M.2 on your motherboard disables some regular SATA ports that could be used by other hard drives/SSDs/DVD drives. Lastly, even if you have a free M.2 port that can take your new NVMe drive, you might want to check if you have the little screws needed to secure it down to the motherboard
4bitマルチセルのQLCタイプのIM Flash Technologies製64層3D NANDが採用されていますが、3bitマルチセルのTLC型SSDと同様の特徴が大容量書き込み時にでており、1TBモデルでは120GB程度のSLCキャッシュを超える書き込みアクセスでは理想値1800MB/sから100MB/sまで書き込み速度が大幅に急落しました。
Intel SSD 660pのSLCキャッシュ容量は総容量の10％なので512GBでは50GB(実効60GB)、1TBGBでは100GB(実効120GB)、2TBでは200GB(実効240GB)となるため、一般ユースで超過することがないであろうSLCキャッシュを備えた1TBモデルか2TBモデルがおすすめです。
My previous disk was 512gb but the restore from time machine has take-over nearly 900gb on the new drive! bizzare, but presume I had a lot on icloud that can now fit on!
The lane width via system report showed as 1. Therefore speeds were half the speed of original drive at 370MBs for read and 380 for write. The whole laptop was sluggish and unresponsive.
After nearly a week of trying to get firmware updates I gave up (Instructions from Intel website don't work on Mojave) . So I prepped Amazon for a return of the drive.
Just in case I reseated the drive and it failed completely coming up with ? in a box. I tried several other reseats with the same result and was convinced I had killed the MacBook!
I put the original disk in and all ok and booted! I could get by! The old ssd showed width of 4 and I had a working laptop. I then did a final full reseat of the new drive including reseat in adaptor, ensuring all the way in until it clicked in the long sintech adaptor (had to be brutal btw).
I rebooted and It went black for a about 3 minutes and I made a coffee. It eventually started to boot.
Was it my imagination or was it fast again?
System Report showed a width of x4. I ran speed checks. Read 1400MBs and Write 1200MBs. Very responsive!
Eats slightly more battery than before, but very marginally as the battery is rather old and worn out showing as poor anyway.
No sleep issues and performed several reboots without issue.
I am now very very happy.
Es handelt sich um QLC speicher mit 1800mb/s mit 1024GB für 130€
Das damit dauerhaft 1800mb/s erreicht werden sollte jedem klar sein. Das wird man bei keinem Hersteller erreichen da ausnahmslos alle Hersteller die Spitzenwerte unter Perfekte Bedingungen angeben.
Ich habe die 1TB Variante gekauft um Daten darauf zu speichern die nicht Ständig gelöscht und neu geschrieben werden.
Genau dafür ist der QLC speicher Perfekt geeignet.
Die 1800mb/s reichen auch vollkommen, bei Spielen merkt man eh keinen unterschied ob die Daten auf einer Sata SSD oder einer PCI Express SSD liegen.
Bei großen Datein komme ich (laut Windows) auf über 1700MB/s.
Bei vielen kleinen Daten (50-200MB) ist man immer noch bei 1000MB/s +-
Wenn der Cache voll ist (beim Schreiben von ca 200GB+) geht die Transferrate auf 100mb/s runter.
Das reicht allemal da es eh kaum Anwendungen oder Spiele gibt die so eine menge an Daten Lesen muss.
Wer darauf Daten für Kunden speichert (die sich beschweren das die Bandbreite einbricht) sollte sich sowieso überlegen ob er nicht den Beruf verfehlt hat, nachdem er so eine SSD in einem Server oder Workstation verbaut hat !!!
Warum zwei? Ich betreibe die zwei SSDs im Raid0 Verbund und komme so auf 3225 MB/s Lesen und 2797MB/s Schreiben. Zum Vergleich, meine Samsung EVO 860 schafft 543MB/s. Das kann sich sehen lassen.
Jedoch ist diese SSD definitiv nicht für Leute die sehr viel Daten Traffic auf der Platte verursachen, da die Garantie bereits bei 200TB bei der 1TB Platte erlischt. Daher verwende ich diese ausschließlich für Games. Die hat man länger drauf und muss überwiegend nur Lesen und das zügig.
Das Laden der Games ist unglaublich schnell!!
Preis/Leistung ist Top! Jedoch ist die Platte nicht für Jeden geeignet. Für Games hingegen ist sie Perfekt, am besten in einem Raid0 Verbund.
