4.0 out of 5 stars Amazing drive, but you MUST format it
By Zenon Sommers on November 10, 2018
The drive itself is amazing. It's tiny, light, and fast as hell, truly living up to the promised 550 MB/s.

That said, if you plan to use this drive for anything other than movies, music, and pictures, you need to format it before using it. This is especially true if you plan to use the drive to back up your phone or computer. Out of the box, the drive is formatted with exFAT and an allocation size of 1 MB. That means that any file less than 1 MB takes up 1 MB of space. 1 MB may not seem like much on a 250 GB-2 TB drive, but with the myriad of small files that show up on backups taking up 1,000x more space than normal, it adds up. See the attached pictures for a small text file taking up 2,700x more space than it actually is and a 177 GB backup taking up an extra 73 GB on the drive.

I mention this because it's an easy fix. According to the command line, the sector size on the drive is 512 bytes, meaning there is no reason to have an allocation size that large. All you need to do is format the drive as exFAT and select a smaller allocation size than 1 MB. Microsoft recommends 128 KB, but you could go as small as 4 KB or as large as 256 KB and still be far more efficient than the factory 1 MB allocation size.

1.0 out of 5 stars 5 years of travel photos loss
By Long on September 26, 2018
This drive is terrible. It was stable for the first month of use, but now, my Lightroom Profile won't load, can't transfer photos off of it.

Every action you do with the drive, whether it be transferring files on, transferring files off, it'll hang randomly. I bought the 1 TB Hard Drive and I can't transfer 5 GB without it hanging at 2-3 GB's and just freezes completely (see attached for error).

Can't open up Lightroom cause the Portfolio freezes before it fully opens. Every hard drive I have on my computer works, except for this one.

5 years of travel photos loss. I am never buying SanDisk again, sticking to Samsung SSDs from now on.

5.0 out of 5 stars The best USB SSD drive that you can buy! Don't look at anything else!
By Ronald Epstein on June 26, 2018
In short, I needed an SSD to back up my MacBook Pro. In the past, I used a spinning hard drive for backup using SuperDuper software and the process was painfully slow. Often, for about 500GB of data, the backup and restore took up to an hour.

With an internal SSD on my MacBook Pro it made perfect sense that the destination backup should also go on an SSD drive where transfer speeds would significantly increase. One more thing to consider: spinning hards drives have a much higher failure rate than SSD drives. I can't begin to tell you how many spinning backup drives I have purchased in the past that have ultimately failed.

SSD is the future and the fact that prices have dramatically decreased on these drives gives no-one an excuse for not buying them.

I did a lot of research on various SSD drives before selecting this SanDisk 1TB drive. My first choice was a Samsung in a colorized metal case. The reviews, however, led me to believe that there were some major issues with the Samsung drives as they included embedded software that was difficult to remove. This is not something anyone wants when buying an SSD drive.

Reading the reviews on this SanDisk Extreme, it was easy to see that this would fit perfectly for my needs. The reviews across the board were very positive. No embedded software. This particular SSD has been rated as one of the very fastest USB drives available on the market as of this date.

Upon arrival, I was astonished at how small this drive actually is. I mean, it's absolutely tiny. You can fit it into your jeans pocket and you would not feel it. We really have come a long way in external SSD drive portability.

I am not particularly happy with the covering on this drive. It's a dust magnet. The second I placed it on my table it had already collected airborne dog hair. However, on the plus side, this thing is so rugged that you can drop it from just about any height and it won't break. So, I guess that is more important than anything else.

It was nice to see that the drive includes a USB-C cord with USB-A adapter. The cord also securely fits the drive without any wiggle. The only thing negative I have to say about the cord is that it's too short.

I am including in my photos the result of a recent backup of my MacBook Pro via SuperDuper software. You can see that about 425GB of data was backed up in 30 minutes time. With a spinning drive, that would have taken 2-3 times longer. This drive is really super fast!

This drive does come formatted for Windows. If you buy it for your Mac, you need to go to DISK UTILITY (in your applications folder), select the SanDisk drive, then click on ERASE. You will want to format the drive in OSX Extended Journaled. The format takes seconds to do. You are then ready to transfer data to the drive.

By far, this is the best SSD drive I have ever owned. Do not hesitate to consider this above any other.

5.0 out of 5 stars Pratique, solide et performant
Reviewed in France on January 1, 2019
Voila maintenant 8 mois que j'utilise ce SSD portable et j'en suis pleinement satisfait. Alors certes, cela coute plus cher qu'un disque dur portable à capacité équivalente et c'est plus gros qu'une clé usb mais finalement cela réunit le meilleur des 2 mondes. Petite comparaison rapide :

avec un disque dur standard :
+ plus petit
+ beaucoup plus rapide
+ plus robuste à l'utilisation (n'oublions pas qu'un disque, c'est mécanique et qu'il faut donc éviter de le bouger lorsqu'il est notamment en cours d'utilisation)
- plus cher à capacité équivalente et capacité moins importante

avec une clé usb
+ beaucoup plus rapide (même en achetant les clefs usb les plus cheres et les plus rapide, ce genre de disque reste nettement plus rapide
+ capacité plus importante
- plus encombrant

PRESENTATION
------------------
Petit récapitulatif fait, parlons du produit en lui-même, le disque est enveloppé d'une coque au toucher "caoutchouteux", cela lui confère un côté anti-dérapant et surtout lui permet d'absorber les chocs en cas de chute. Seule la partie supérieure est surmontée d'une plaque en plastique. Il est équipé d'un "oeil" qui permet de l'accrocher à un porte-clé. Bref, très bonne sensation sur la qualité de fabrication, clairement un produit qu'on n'hésite pas à transporter partout !
Il dispose d'un port usb-c et est fourni avec un petit cable usb-c vers usb-c ainsi que d'un adaptateur usb-c vers usb traditionnel
Il est fourni avec des utilitaires afin de crypter les données (que je n'ai jamais utilisé)

PERFORMANCES
--------------------
Autant le dire tout de suite, ce SSD est très performant (comparativement à 99% des périphériques de stockage portable). Plutot que de sortir des débits théoriques, je préfère donner quelques chiffres concrets de cas d'utilisation
Sous windows (depuis un SSD)
- copie (écriture) de 1050 photos (1Go envion) -> 7 secondes (150Mo/s)
- copie (écriture) d'un fichier de 20Go -> 1min10 (300Mo/s)
Sur un macbook pro (possédant un SSD très performant)
- lecture d'un fichier de 20Go -> 40 secondes (500Mo/s)
- écriture d'un fichier de 20 Go -> 53 secondes (380Mo/s)

Comme vous pouvez le constater, les performances vont grandement dépendre du système sur lequel sera branché ce disque (interface usb, disque depuis ou sur lequel sont copiées les données, performances du système général) mais les performances du disque en lui-même sont excellentes.
Plus de craintes a avoir lorsque vous devez copier 50 Go de photos ou autre fichiers, cela ne prend pas 30min ou 1h mais seulement quelques minutes ce qui est fortement appréciable si vous devez régulièrement transférer des fichiers.

Pour conclure, il s'agit la d'un excellent disque portable (attention à la longeur du cable très courte, qui ne me dérange pour ma part absolument pas), très rapide et très robuste. A voir sur la fiabilité mais sur ce point j'ai rarement été déçu par SanDisk.

N'hésitez pas à indiquer si vous avez trouvé ce retour utile

5.0 out of 5 stars Excellent small and fast SSD Hdd
Reviewed in the United Kingdom on February 3, 2019
I bought the 500GB version, it is veramenet small and very nice.
Obviously it is also very fast.
I bought it to make a backup system for photographs while traveling.
These are the components:
1 - OTG cable, to connect the smartphone to the HUB
2 - USB hub 3 with 4 ports, on a smartphone with powerful batteries there is no need for power supply. But on a smartphone with a low battery there is a need for the power supply
3 - memory card reader, I got one that reads both SD and CF
4 - HDD extreno with sufficient capacity to backup, I have used a 500 GB SSD
With this system from the smartphone I can see both the memory card and the HDD and you can copy the photos directly from the memory card to the HDD. I have done various tests and to copy 8/10 GB of photos takes about 8/12 minutes, depends on the speed of the memory card. So a copy speed of about 15/20 MB / sec.

5.0 out of 5 stars Premium external drive
Reviewed in the United Kingdom on April 13, 2018
Let’s get the elephant in the room addressed first; there is a previous version of this drive that had issues with the USB port; it had a tendency to break. [[ASIN:B01NB1IJ7J SanDisk 500 GB Extreme 500 Portable Solid State Drive]]

The drive under review here has a redesigned case that looks like it specifically fixes the issue.

The drive itself is a standard SSD motherboard (i.e. what you see when you open a standard 2.5 inch SSD case), attached to a USB interface board and encased in a sturdy housing (front face is plastic, edges and back are rubber so if you drop the drive it will most likely hit the ground on the rubber edges... or for the pedantic, the chance of it landing flat on its plastic front face is about 1 in 360 or you really have to be trying to break it!).

So knowing all this, the first question is 'what drive is it internally'? Rather than open the drive and potentially break it, there are sneakier ways; I used CrystalDiskInfo to see what the firmware revision was, and then Googled it to see what other products have the same revison. The firmware is 'X61110RL', and the product is Sandisk Ultra 3D SSD, and for my 500GB drive, the equivalent sized SSD is [[ASIN:B072R78B6Q SanDisk Ultra 3D SSD 500GB up to 560MB/s Read / up to 530MB/s Write]]
This tells us that the underlying SSD is not an old drive Sandisk are trying to sell off, but one of their latest models. It also tells us the underlying drive is capable of being faster than the stated specs for the portable drive package.

The drive is light and pocket sized as long as you unplug the supplied cable and pocket it separately. The cable is a type C on both ends, (looks like a microUSB but a little larger) with an adapter to give you a full USB on the computer end of the cable. They've done it this way so the same cable works on both PC and Macbooks that use the slimmer type C.

In use, read and write speeds vary (depending on hardware connected to). The highest I got was on my MSI gaming laptop which gave me 370Mb/s. This was a constant 370Mb/s and I think it is the cable or my computer rather than the drive itself that is the limiting factor. I will update the review when and if I get a better transfer rate, but this is still a very decent rate for an external drive! EDIT: Ive got up to 420MB/s since writing this review. I only get this high rate for large sequential files, but for more normal use cases, I see 250-350Mb/s which is in-line with internal SSDs.

I tested the drive by copying over my Lightroom library (about 200GB) and also some more onerous tasks (backing up a ReactJS project, which is about 200MB of small files, most less than 10k). I also tried to install and play a game from the drive, and it all worked well, so no problems! The only minor thing I noticed was that the drive does get warm for extended constant use. If you reformat the drive (which you may do if you follow my advice to reformat to NTFS) and do a full format, the drive gets very hot (50C), but that is probably an edge case.

I have a BlackMagic cinema camera that shoots cinemaRaw and high bitrate Prores, and I will be using this drive to back-up files out in the field (once the weather allows it!) and will report back if any issues.

Things liked about the drive;

It’s smaller than a standard SSD into a USB caddy (7.5x12.5cm vs 5x9.5cm), plus its much lighter.

Because the drive is solid state, you never need an external power supply, and you can leave it attached to a battery powered laptop without the drive being a drain. It is also better suited to taking knocks than a mechanical hard drive.

Downsides;

Cost. Its more expensive than a standard SSD in a USB caddy. The cost also means that you would not use this drive for occasional archiving; you are more likely to use it to back up data often and quickly. Typical use cases might be wedding photography or on-location videography. In both cases, the user is performing content creation where the subject will not wait, so I guess that is the main target use case.
Just backing up your documents folder every month does not have the same urgency because 'the subject will wait'.
An additional use case I have found is 'when you have lots of small files'. Mechanical hard drives are VERY slow here. SSDs are also slower than their reported maximum but more bearable because the speed will still be decent (tens of MB/s rather than down to hundreds of kb/s). If you are programmer (and especially if you are a web or game developer) this drive might be useful.

The cable has two parts to it if you are on PC (Mac users get to use the cable without the adapter bit so it isn't an issue for them), making it a bit clunky. Like me, you might elect to buy a better one-piece cable.

The drive comes formatted as exFAT, which is fine unless you have lots of small files. I tried to backup 14GB of JS projects and the space on the disk was more than 200GB with the default exFAT settings. A reformat to NTFS got it down to about 14.2GB. If you are using this drive in this way or to install/run applications from you may want a reformat. Not really a downside though as all external drives have the issue as exFAT is the most compatible.

There's no power or data indication on the body.

Who would buy this?

Photographers, videograpers and anyone else who needs backup storage that is quick enough to not slow you down, and also needs low power requirements and ruggedness. Videographers with models that can output streams via USB will find this drive particularly compelling. It's also useful if you are videographer who uses something like Premiere on a laptop in the field, but renders the footage out on a desktop. Keep your project on the SSD and edit from it, and you get both portability and speed!

Programmers (especially ones like me who don’t totally trust svn/git when your project contains lots of graphics!).

Anyone who wants to play films or other media on a projector/tablet or other device that accepts data through USB; the advantage of this drive is that it wont require its own power supply and won't drain the player's battery.

Anyone who wants to run applications or games from an external drive.

Anyone who relies on USB drives and wants something faster or with more capacity. This is essentially the fastest USB drive you can get; just as robust as a USB drive (albeit a fair bit bigger) but much faster because its really an SSD!

And of course finally, anyone who just wants the best! If you have shelled out on an expensive laptop or desktop and don't want any bottlenecks, then this is a pretty sweet peripheral to throw some cash at!

Overall, I really like this drive. I’d give it 4.5 stars if I could (the cable loses half a mark) but I’ll go for the full 5 as I’ve just searched on the cost of a better, high bandwidth braided data cable and its peanuts!

EDIT: I've included a photo showing relative size of the Sandisk drive vs a standard portable 2.5 inch hard drive. I've also tried to be clever by using a clear hard drive caddy so you can also see the size of the standard hard drive itself.

EDIT: The Additional 'cheap' cable I ordered turned out to be cheap because its not USB3! The one I ended up buying is not cheap but is perfect; [[ASIN:B0756WJPZQ USB Type C Cable, USB C to USB 3.0 Cable, TecMad Type C 3.0 Short high speed Data Sync Cable 0.2M [0.65FT] Durable Nylon Braided Cable Fast Sync&Data Cable for Apple new MacBook, Huawei P9/P10 Honor 8 Pro, Galaxy s8 + note 8 ,Wileyfox Swift 2/2 Plus/2X,Nintendo Switch- Gray]]
Buy the shorter ones as they will have the least effect on transfer rate.

(but still pretty fast).

I was wondering if the SSD was living up to SanDisk's promise of Read Speeds of up to 550MB/s and attached it to my Macbook Pro with Thunderbolt 3 port. I used BlackMagicDesign's Disk Speed Test. I first tested the internal Apple SSD and got 1329 MB/s write and 2209 MB/s read speed (see first picture).

I then switched drives and tested my SanDisk 1TB SSD (see second picture). Write speed was about 411MB/s and Read speeds around 506MB/s. That is about 90% of advertised max read speed. I would have expected 100%, especially at this price point and having tested it on a computer, which certainly checks all the requirements.
