asked on USB3 portable fast backup disk required for server's backup - must be better than Adata's 100MB/s
Need to buy fast USB 3.0 or higher portable 2TB USB 2.5" disk based on either standard disk with rotating platters or the hybrid (SSHD). At the moment we are using Adata HD710 which are reaching 100 MB/s. This is fine but I am looking to check if I can get anything faster as we have lots of data. We like Adata as it is rugged and I have used about 20 of them with only one failure (replaced under warranty). The portable usb drive will be used as a backup disk overnight but will be carried off site by users in their purses (can't be too big, too heavy and needs to be shockproof).
I was looking at online reviews but there is always some bad review or the device has good performance on one site and worse on the other, hence I am asking for your experience. I was eve thinking about buying 2.5" internal SATA drive and putting it into rugged enclosure but then even rugged enclosures have bad reviews.
But I will be honest: performance is very important so getting speeds of over 130 Mb/s would be tempting to switch. We will use this on Windows Server machine.

Aha...budget..the only problem that Computer Science will never solve
What kind of ports do you have on the server? Do you have a USB v3.1 port? Do you have an eSATA port?
If USB3.0 is not a hard requirement, then you might be able to add one of these higher speed ports and a corresponding drive. You could also consider Thunderbolt connectivity. Of course, you'll eventually get to the point of pushing the HDD maximum limits, so perhaps the possible benefits are somewhat limited.

100MB/s if this is write my USB3 flash drive is faster!
I think you will find spinning rust too slow

Why not consider network backups to a NAS with removable disks!
maybe..instead of chasing higher hdd speeds you should focus on having backups of smaller size..like compressing them....a 40gb sql backup with compression(7zip,winrar) can shrink to 4gbs

We have lots of data and it is already compressed by Acronis backup software.
We definitely need 2.5" disks.
I saw performance tests of some 2.5@ internal 7200rpm SATA disks reaching 168 Mb/s. I thought I might use then with enclosure and take advantage of the USB 3.0.
Just wanted to check what others might be using as I would like to get tested and recommended device.

Well if you need 2.5 inch disks the fastest we're the WD Velociraptor 10,000 RPM
But spinning rust is coming to and end and ad 2.5 inch were used a lot in laptops that's now ended for SSD flash mSATA SSD so 2.5 spinning rust development is over coming to an end
You search maybe in vain!

We don't use USB backup or 2.5 inch disks
We use this new thing people call Cloud!

We have cloud backup too but with 900GB of data, it is faster to restore it from USB then download or wait for the disk from Cloud backup company.
Tom what about my post regarding 10K and 15K drives?
Are any 10K or 15K 2.5inch drives currently in production?

DeDuplucation!

Acronis backup software has built-in deduplicatipon.
I am not sure there are 2.5" 10k and 15k SATA internal drives.
I looked into it and found 2.5" WD Black series which are now called Performance with 7200rpm but that goes only up to 1TB. On the other hand, Seagate Pro 2.5" has performed not as good in some benchmarks.
I think keeping it as it is with 2TB or 3TB disks will still accomplish the task overnight while ticking most of the boxes, we will get more space with 3TB so more backups can be stored there for not so much and then once USB 3.1 gen2 (or better) disks with SSD become cheaper we will switch to them (there are not so many USB supporting the latest specification of USB 3.1 anyway.

why would you want 2.5 disks??
you never mentioned that

I guess he wants 2.5 hdds for best portability...a 2.5 external drive is much easier to carry... ...i guess the plan is to take backup just before the end of shift and carry all the data to home...the problem is that due the size of data it takes too long and tries to minimize the time of writing the data from the server to portable drive...

I did mention that in the question: "The portable usb drive will be used as a backup disk overnight but will be carried off site by users in their purses (can't be too big, too heavy and needs to be shockproof)."
i missed the overnight ...anyway portability is your main reason..
well although 3.5disks are heavier and bigger than their2.5 brothers, i can't see that as a real obstacle

This question was asked to explore options. Thank you for all your input. We will stick to current Adata USB 3.0 portable drives and wait for SSDs to become cheaper. To be honest, we also have cloud and Tape drive, but I was wondering if there is another way as we recently found out that we cannot use Acronis Recovery Disk with tapes.
I know that it may sound silly, but even improvement of 30% - 50% of speed would cut the backup time significantly and hopefully still be within our budget.
