Adata SE730

£106 inc VAT (46p per GB) •

PC Advisor - - CONTENTS -

Adata’s SE730 is a brand-new por­ta­ble solid-state drive (SSD), which com­bines the best of all worlds: it’s one of the small­est we’ve seen, it’s wa­ter­proof and it has a blis­ter­ing speed that few of its ri­vals can com­pete.


The one snag is the price. How­ever, while it’s more ex­pen­sive than a lot of por­ta­ble SSDs, the ex­tra cost is worth it. As it’s so new, it’s not widely avail­able and we ex­pect the price to drop be­low £100 soon. At the time of writ­ing, it cost 46p per GB, mak­ing it more ex­pen­sive than the SanDisk Ex­treme 500 and Sam­sung T3.

Fea­tures and de­sign

Don’t con­fuse the new SE730 with the older drive of the same name: the new one has a com­pletely dif­fer­ent de­sign. It’s avail­able in only one ca­pac­ity – 250GB – but you do get a choice of gold or red. Be­hind one of the plas­tic end caps is a USB-C con­nec­tor, which sup­ports USB 3.1 Gen 2. This is the lat­est USB stan­dard, ca­pa­ble of up to 10Gb/s (1250MB/s). That’s the the­o­ret­i­cal speed, of course, and Adata claims up to 550MB/s from the SE730, which em­ploys MLC NAND flash – higher qual­ity than many drives which use TLC.

It has a three-year war­ranty (many drives come with only two years) and is IP68 cer­ti­fied. Un­less you hap­pen to know the IP rat­ings off by heart, this means it’s wa­ter-re­sis­tant up to 1.5m for one hour and is also dust proof. Adata says it’s shock proof to mil­i­tary stan­dards, so it will shrug off the odd drop onto con­crete.

You can use it with an An­droid phone that sup­ports OTG, though you’ll need a sep­a­rate USB-C to Mi­cro-USB cable as only a short full-size USB cable is pro­vided. There’s no en­cryp­tion, so if you need to store and carry sen­si­tive data, this isn’t the best choice.


All of these in­gre­di­ents add up to great per­for­mance, even if the fig­ures from Crys­talDiskMark were quite a bit short of Adata’s claims. We saw a se­quen­tial read speed of 381MB/s and a write speed, which al­most kept up at 278.5MB/s.

Ran­dom 4KB reads weren’t much bet­ter than cer­tain ri­vals at 20MB/s, but it’s when writ­ing them that the Adata shines: it man­aged 38.9MB/s, which is by far the fastest we’ve seen from a por­ta­ble drive. Most lan­guish around 1- to 4MB/s, in­clud­ing the SanDisk and Sam­sung SSDs. Ob­vi­ously, this is of lit­tle con­se­quence if you’ll mainly use the SE730 for stor­ing large files, but it’s great if you want to back up lots of lit­tle ones.


Typ­i­cally if you want a tiny, high-ca­pac­ity drive you have to sac­ri­fice per­for­mance, but not with the SE730. It re­ally is a pocket rocket, and well worth the price if you need speedy por­ta­ble stor­age. Jim Martin
