(SD) MicroSD benchmarks!

[Streetwise]

Hello

Sorry for the confusion, well, the truth is I haven't heard of any being certified of being uhs-I, but it doesn't mean that they cannot support the speeds.

Also note that mobile devices mainly utilize random speeds more over the main bus speed (which is the one used for recording constant larger streams)

Now, the only catch here is that I have not used a mobile device to run the review because of:
1) Each device has its own characteristics (I'm looking at Samsung here) when it comes to the cards support
2) Software plays a part in the device
3) The way the differential os handles the file structure etc

The 4K needing 30mb/s is just a benchmark set by the industry, but, it may or may not even require that bandwidth (realistically) as it again, depends on the bitrate of the recording.

Nonetheless, we would not know if the various devices will support the higher performance or trottle it, unless we test them (both card and devices) one by one, or they say they support the ultra high speed bus standard.

Thank u for the clarification, got it . Believe u understand where I'm coming from; looking to see what is the minimun card speed req'd to shoot 4k video on a mobile device.....in this case, a Samsung Note 4 .

Well, if I'm not wrong, at full res, it records at 48mbps which using a normal samsung evo or sandisk ultra won't be able to hit the mark.

As far as I understand, if the card doesn't meet the mark, most systems will still try to record and then buffer the backlog into the system and slowly record it.

Thanks for the information. Well, to play safe, I went ahead to purchase a Samsung Pro 64Gb. Tried recording a 1 min video and all seems fine with no buffering.

Cool!

Glad to see you enjoying

Dont forget to keep the receipt and packaging to mantain warranty!

Thanks. It's good to see reviews with more details and how the various speed tests relate to product usage.

got one today for $17.95 32GB Class 10 at ntuc xtra

tested with SD Tools
write speed 7~10mb/s
read 18mb/s

Sounds like the card is either bad or the test got something wrong

 

[cannotliao]

i tested with SD tools

write
1st test 7.4mb/s
2nd test 9.6mb/s
3rd test 8.5mb/s
4th test 9.1mb/s
5th test 9.4mb/s

read always able to get 18+mb/s

Might be the phone.

Fake SanDisk Ultra UHS-I (8GB Listed As 64GB) [Including Fake Samsung Evo Sample]

In recent years, counterfeit products have been growing in its availability and many popular brands are among those hit hard. SanDisk, Samsung are just a few larger and more popular victims for memory cards. Today, we have managed to grab a sample of a fake SanDisk MicroSD card that we purchased from a merchant in Qoo10 Singapore.

Today’s sample is a typical sample from a seller on Qoo10 Singapore, however, the merchant has since removed the fake SanDisk and Samsung memory card listings.

Like most of the pirated SanDisk cards that we have encountered, they come in pretty convincing retail packages, like the one shown above. The consolation is that at this point of time, it seems to be limited to Ultra (OLD SERIES) style of packaging, and the Extreme variant with wrong speeds printed on the packaging. However, this may change as the counterfeiters get smarter.

Reviewed: SanDisk Standard Class 4 microSD (32GB)

For comparative purpose, we have decided to include a original SanDisk Standard microSDHC card, of their highest capacity – 32GB, in the speedtest. At class 4, do we expect to see anything spectacular? Well, I don’t think so, but let us take a look at this now!

my average/ending write speed with various Kingston class 4 microsds for transferring large video files are similar - 4.7-4.8 MByte/s

is there a difference in the transfer speed of different microsd usb adapters ? I just use those cheap $1 generic items.

microSD to USB direct? Oh yes it will make a difference, though mainly on the higher end cards and well, considered relative negligible on the lower end cards. (Mainly when the cards are touting USB3/UHS-I/UHS-II as the main speed boosters)

UHS-II microSD will be coming this or next month [as we are told]

Winners For Our microSD Giveaway!

It took quite a while for us to complete this whole microSD testing campaign, but now that it is over, its time to giveaway the prizes! Back in September last year, we mentioned we have one microSD (64GB) to give but over this period, it has multiplied to five, (comprising of 1 x SanDisk Extreme, 1 x Samsung Evo, 1 x Kingston UltimateX, 2 x SanDisk Ultra)! Find out if you are one of the lucky winners!

benchmark like this is useful, i buy only with better marks

in Qoo10, there is a SLS 6th floor shop selling the SAMSUNG EVO microSD 64GB at $35 + 1 free 8GB Sandisk Cruzer Blade (limited). factor in the discount coupons and if you sell the 8GB Sandisk for $4, the 64GB card is around $28, it seems like a good buy.

Reviewed: Sandisk Ultra MicroSDXC [128gb]

After we took a look at all the microSD’s from the 64GB, the next consumer category that is up and rising is the 128GB category. Right now, it is limited to mainly this 3 brands: Lexar, SanDisk and Samsung. SanDisk was the pioneer in this category, being the first to release their line of 128GB microSD card offering (and more recently, 200GB). Released under the Ultra series, which is their lower end of the microSD offering for microSDXC cards, the card itself costs over $100 and is more than 3x the cost of a 64GB SandDisk Ultra microSD card on street value, how worthwhile is this card in terms of performance?


Summary:

The read speed is pretty close to its claim and its predecessor (64GB), but the write speed however, is without doubt, slow. It is the slowest amongst the 3 x 128GB microSD cards and thus, nothing spectacular either with the standard 10 year warranty. If you are in dire need for memory space just like me, this card could be considered although there are better alternatives. However, if your budget is a little constrained, this would be a better replacement over that of Lexar for the price or Samsung for the ease of warranty.

Reviewed: Lexar High-Performance UHS-I 633x microSDXC [128GB]

After we took a look at all the microSD’s from the 64GB, the next consumer category that is up and rising is the 128GB category. Right now, it is limited to mainly this 3 brands: Lexar, SanDisk and Samsung. After SanDisk released their 128GB, they had close to no competition until Lexar joined in the fun. Slotted into their highest end series, its a stark contrast to the competitors who put it into their lowest end series.

Summary:

As we can see in the results, the performance, whilst exceeding its rating and certificated results, is still, however, a far cry from its predecessor of 64GB in performance. In terms of 128GB performance, however, this card still holds the crown but overall, the performance like the other 128GB microSD cards, are a disappointment. If Lexar had branded this as the 300x variant instead, this card could have saved quite a bit of reprieve. However, with the price tag on the street close to that of the SanDisk and Samsung, and the fact that this is a MLC based card, and a powerful lifetime warranty for the card (1 year for the card reader), there is no reason to shun this card, considering its superiority all round.

Right now, it is limited to mainly this 3 brands: Lexar, SanDisk and Samsung. Samsung is the last of the 3 big brands to put their offerings onto the market, and they have released this under their Samsung EVO line, which is their mid-range or rather, lowest end offering for the microSDXC series.

Summary:

Overall, the speed here is pretty much similar and consistent with the 64GB counterpart, less the random speed performance for some unknown reason. In fact, this is the card that showed the closest performance to cards in the same series. This card seems pretty cool compared to the SanDisk variant but it clearly loses out to the higher end Lexar card. However, there are reports of this card melting after a prolonged data transfer although we have not actually faced this issue.

That said, backed with a 10 year warranty, similar to that of SanDisk, having a slightly faster speed than SanDisk and priced similarly to SanDisk, it is worthwhile to consider this baby, although the street price for the Lexar has made it similar to them all. As such, we recommend you to take a look at Lexar‘s offering first before considering this.

If there is demand, I will go get the Samsung Essentials for the review as well this week... Please do sound out!
