Priced at $55 for 256GB, there’s also a 128GB version available for $30, both within an all-aluminium enclosure. It joins the ranks, of course, of the Raspberry Pi accessories such as the Raspberry Pi SD Cards, SSDs and USB 3 Hub.
Raspberry Pi Flash Drive
Helen Lynn, Director of Communications at Raspberry Pi, writes:
“We’ve brought our usual exacting standards and attention to detail to our new accessory. It can sustain a write speed of 75MB/s (128GB variant) or 150MB/s (256GB variant), and our thorough testing has made sure it can handle the demands of real life when it comes to sudden disconnection and power failure.”
“Its ergonomic all-aluminium enclosure is easy to grasp and almost impossible to break, although you’ll manage it if, like jdb of this parish, you go at it with a blowtorch. It has an attachment hole so you can keep it on a keyring or similar. The Raspberry Pi logo is etched with classy understatement onto its upper surface.”
Pseudo-SLC
Note that the drives employ a small reservation of pseudo-SLC cache to improve performance under burst-y write workloads. They also enable SSD-style SMART health reporting, giving insights into device lifespan. Additionally, they support TRIM operations (an Advanced Technology Attachment (ATA) command) for avoiding data blocks no longer in use, to help improve write performance.flash
Talking of which, the detailed access specs for the Raspberry Pi Flash Drive are as follows:
The 128GB version
- 16k IOPS2 (4kB random reads)
- 21k IOPS (4kB random writes)
- 75MB/s sequential write speed (sustained)
The 256GB version
- 18k IOPS (4kB random reads)
- 22k IOPS (4kB random writes)
- 150MB/s sequential write speed (sustained)
